[android] How do I make a splash screen?

I wanted to make my app look more professional, so I decided that I wanted to make a splash screen.

How would I create it and then implement it?

Though there are good answers, I will show the google recommended way:

1)First create a Theme for splash screen: you have a theme called splashscreenTheme, your launcher theme would be:

<style name="splashscreenTheme">
  <item name="android:windowBackground">@drawable/launch_screen</item>
</style>

Note:

android:windowBackground already sets your splashscreen image no
need to do this in UI again.

you can also use color here instead of a drawable.

2)Set the theme to manifest of splashscreenActivity

   <activity
            android:name=".activity.splashscreenActivity"
            android:screenOrientation="portrait"
            android:theme="@style/splashscreenTheme">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

3)make sure you launch_screen drawable is not in drawable folder if your image is not small.

It will result in faster launch screen start and save you from the black screen

It also avoids extra overdraw

This is the best post I've seen on splash screens: http://saulmm.github.io/avoding-android-cold-starts

Saúl Molinero goes into two different options for splash screens: Taking advantage of the window background to animate into your initial screen and displaying placeholder UI (which is a popular choice that Google uses for most of their apps these days).

I refer to this post every time I need to consider cold start time and avoiding user dropoff due to long startup times.

Hope this helps!

In Kotlin write this code:-

 Handler().postDelayed({
            val mainIntent = Intent(this@SplashActivity, LoginActivity::class.java)
            startActivity(mainIntent)
            finish()
        }, 500)

Hope this will help you.Thanks........

Splash screen is a little unusable object in Android: it can not be loaded as soon as possible for hiding the delay of main activity starting. There are two reasons to use it: advertising and network operations.

Implementation as dialog makes jump without delay from splash screen to main UI of activity.

public class SplashDialog extends Dialog {
    ImageView splashscreen;
    SplashLoader loader;
    int splashTime = 4000;

    public SplashDialog(Context context, int theme) {
        super(context, theme);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash);
        setCancelable(false);

        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                cancel();
            }
        }, splashTime);

    }
}

Layout:

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@color/white">

    <ImageView
        android:id="@+id/splashscreen"
        android:layout_width="190dp"
        android:layout_height="190dp"
        android:background="@drawable/whistle"
        android:layout_centerInParent="true" />

</RelativeLayout>

And start:

public class MyActivity extends ActionBarActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        if (getIntent().getCategories() != null &&  getIntent().getCategories().contains("android.intent.category.LAUNCHER")) {
            showSplashScreen();
        }
    }

    protected Dialog splashDialog;
    protected void showSplashScreen() {
        splashDialog = new SplashDialog(this, R.style.SplashScreen);
        splashDialog.show();
    }

    ...
}

Simple Code, it works:) Simple splash

int secondsDelayed = 1;
    new Handler().postDelayed(new Runnable() {
        public void run() {
            startActivity(new Intent(LoginSuccessFull.this, LoginActivity.class));
            finish();
        }
    }, secondsDelayed * 1500);

Its really simple in android we just use handler concept to implement the splash screen

In your SplashScreenActivity java file paste this code.

In your SplashScreenActivity xml file put any picture using imageview.

public void LoadScreen() {
        final Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {                 
                Intent i = new Intent(SplashScreenActivity.this, AgilanbuGameOptionsActivity.class);
                startActivity(i);
            }
        }, 2000);
    }

Note this solution will not let the user wait more: the delay of the splash screen depends on the start up time of the application.

When you open any android app you will get by default a some what black screen with the title and icon of the app on top, you can change that by using a style/theme.

First, create a style.xml in values folder and add a style to it.

<style name="splashScreenTheme" parent="@android:style/Theme.DeviceDefault.Light.NoActionBar">
    <item name="android:windowBackground">@drawable/splash_screen</item>
</style>

Instead of using @android:style/Theme.DeviceDefault.Light.NoActionBar you can use any other theme as a parent.

Second, in your app Manifest.xml add android:theme="@style/splashScreenTheme" to your main activity.

<activity
        android:name="MainActivity"
        android:label="@string/app_name"
        android:theme="@style/splashScreenTheme" >

Third, Update your theme in your onCreate() launch activity.

protected void onCreate(Bundle savedInstanceState) {
    // Make sure this is before calling super.onCreate
    setTheme(R.style.mainAppTheme);
    super.onCreate(savedInstanceState);
}

UPDATE Check out this post.

Thanks to @mat1h and @adelriosantiago

you will not use a layout file. Instead, specify your splash screen’s background as the activity’s theme background. To do this, first create an XML drawable in res/drawable.

Note: all code below is available GitHub Link

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:drawable="@color/gray"/>

    <item>
        <bitmap
            android:gravity="center"
            android:src="@mipmap/ic_launcher"/>
    </item>

</layer-list>

Here, I’ve set up a background color and an image.

Next, you will set this as your splash activity’s background in the theme. Navigate to your styles.xml file and add a new theme for your splash activity:

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
    </style>

    <style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
        <item name="android:windowBackground">@drawable/background_splash</item>
    </style>

</resources>

In your new SplashTheme, set the window background attribute to your XML drawable. Configure this as your splash activity’s theme in your AndroidManifest.xml:

<activity
    android:name=".SplashActivity"
    android:theme="@style/SplashTheme">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

Finally, your SplashActivity class should just forward you along to your main activity:

public class SplashActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Intent intent = new Intent(this, MainActivity.class);
        startActivity(intent);
        finish();
    }
}

Notice that you don’t even set up a view for this SplashActivity. The view comes from the theme. When you set up the UI for your splash activity in the theme, it is available immediately.

If you did have a layout file for your splash activity, that layout file would be visible to the user only after your app has been fully initialized, which is too late. You want the splash to be displayed only in that small amount of time before the app is initialized.

Really easy & gr8 approach :

• First create your splash with the following website :

  https://www.norio.be/android-feature-graphic-generator/

  Choose your logo and slogan, choose your beautiful background. resize it to 4096x4096.

• Now download that picture and uplodate it to :

  https://apetools.webprofusion.com/app/#/tools/imagegorilla

  And generate all the splash screens needed, all devices, all platforms.

Enjoy!

There are enough answers here that will help with the implementation. this post was meant to help others with the first step of creating the splash screen!

Sometime user open the SplashActivity and quit immediately but the app still go to MainActivity after SPLASH_SCREEN_DISPLAY_LENGTH.

For prevent it: In SplashActivity you should check the SplashActivity is finishing or not before move to MainActivity

public class SplashActivity extends Activity {

    private final int SPLASH_SCREEN_DISPLAY_LENGTH = 2000;

    @Override
    public void onCreate(Bundle icicle) {
        ...
        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {

                if (!isFinishing()) {//isFinishing(): If the activity is finishing, returns true; else returns false.
                    startActivity(new Intent(SplashActivity.this, MainActivity.class));
                    finish();
                }

            }, SPLASH_SCREEN_DISPLAY_LENGTH);
        }                             
   }                                
}

Hope this help

This is the full code here

SplashActivity.java

public class SplashActivity extends AppCompatActivity {

private final int SPLASH_DISPLAY_DURATION = 1000;

@Override
public void onCreate(Bundle bundle) {
    super.onCreate(bundle);


    new Handler().postDelayed(new Runnable(){
        @Override
        public void run() {

            Intent mainIntent = new Intent(SplashActivity.this,MainActivity.class);
            SplashActivity.this.startActivity(mainIntent);
            SplashActivity.this.finish();
        }
    }, SPLASH_DISPLAY_DURATION);
}}

In drawables create this bg_splash.xml

<?xml version="1.0" encoding="utf-8"?><layer-list xmlns:android="http://schemas.android.com/apk/res/android">

<item
    android:drawable="@color/app_color"/>

<item>
    <bitmap
        android:gravity="center"
        android:src="@drawable/ic_in_app_logo_big"/>
</item></layer-list>

In styles.xml create a custom theme

<style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
    <item name="android:windowBackground">@drawable/bg_splash</item>
</style>

and finally in AndroidManifest.xml specify the theme to your activity

<activity
        android:name=".activities.SplashActivity"
        android:label="@string/app_name"
        android:screenOrientation="portrait"
        android:theme="@style/SplashTheme">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

Cheers.

A Splash Screnn, by default, does not automatically make your Application look more professional. A professionally designed Splash Screen has a possibility of making your Application look more professional, but if you do not know how to write one then how professional will the rest of your Application actually be.

About the only reason (excuse) to have a Splash Screen is because you are doing a massive amount of Calculations or are waiting for GPS/WiFi to startup because your Application relies on that prior to it starting. Without the result of those Calculations or access to GPS/WiFi (etc.) your Application is dead in the water, thus you feel you need a Splash Screen, and MUST block the view of the Screen for any other running Programs (including the Background).

Such a Splash Screen ought to look like your Full Screen Application to give the impression that it has already initialized, then after the lengthy calculations are completed the final details could be filled in (the Image tweaked). The chance of that being the case or that it is the only way the Program could be designed is mighty small.

It would be better to allow the User (and the rest of the OS) to do something else while they wait rather than design your Program to be dependant on something that will take a while (when the duration of the wait is uncertain).

There are Icons on your Phone already that say that GPS/WiFi is starting. The time or space taken up by the Splash Screen could be spent loading pre-calculations or actually doing the Calculations. See the first Link below for the problems you create and what must be considered.

If you absolutely must wait for these Calculations or GPS/WiFi it would be best to simply let the Application start and have a pop-up that says that it is necessary to wait for the Calculations (a TEXTUAL "Initializing" Message is fine). The wait for GPS/WiFi is expected (if they were not enabled in another Program already) so announcing their wait times are unnecessary.

Remember that when the Splash Screen starts your Program IS actually running already, all you are doing is delaying the use of your Program and hogging the CPU/GPU to do something that most do not feel is necessary.

We had better really want to wait and see your Splash Screen every time we start your Program or WE will not feel it is very professionally written. Making the Splash Screen FULL Screen and a duplicate of the actual Program's Screen (so we think it is initialized when in fact it has not) MIGHT accomplish your goal (of making your Program look more professional) but I would not bet much on that.

Why not to do it: http://cyrilmottier.com/2012/05/03/splash-screens-are-evil-dont-use-them/

How to do it: https://encrypted.google.com/search?q=Android+splash+screen+source

So there is a good reason not to do it but IF you are certain that somehow your situation falls outside those examples then the means to do it is given above. Be certain that it really does make your Application look more professional or you have defeated the only reason you gave for doing this.

It is like a YouTube Channel that starts every Video with a lengthy Graphic Intro (and Outro) or feels the need to tell a Joke or explain what happened during the past week (when it is not a Comedy or LifeStyles Channel). Just show the show ! (Just run the Program).

Above all answers are really very good. But there are encounter problem of memory leakage. This issue is often known in the Android community as "Leaking an Activity". Now what exactly does that mean?

When configuration change occurs, such as orientation change, Android destroys the Activity and recreates it. Normally, the Garbage Collector will just clear the allocated memory of the old Activity instance and we're all good.

"Leaking an Activity" refers to the situation where the Garbage Collector cannot clear the allocated memory of the old Activity instance since it's being (strong) referenced from an object that out lived the Activity instance. Every Android app has a specific amount of memory allocated for it. When Garbage Collector cannot free up unused memory, the app's performance will decrease gradually and eventually crash with OutOfMemory error.

How to determine whether the app leaks memory or not? The fastest way is to open the Memory tab in Android Studio and pay attention to allocated memory as you change the orientation. If the allocated memory keeps on increasing and never decreases then you have a memory leak.

1.Memory leak when user change the orientation.

First you need to define the splash screen in your layout resource splashscreen.xml file

Sample Code for splash screen activity.

public class Splash extends Activity {
 // 1. Create a static nested class that extends Runnable to start the main Activity
    private static class StartMainActivityRunnable implements Runnable {
        // 2. Make sure we keep the source Activity as a WeakReference (more on that later)
        private WeakReference mActivity;

        private StartMainActivityRunnable(Activity activity) {
         mActivity = new WeakReference(activity);
        }

        @Override
        public void run() {
         // 3. Check that the reference is valid and execute the code
            if (mActivity.get() != null) {
             Activity activity = mActivity.get();
             Intent mainIntent = new Intent(activity, MainActivity.class);
             activity.startActivity(mainIntent);
             activity.finish();
            }
        }
    }

    /** Duration of wait **/
    private final int SPLASH_DISPLAY_LENGTH = 1000;

    // 4. Declare the Handler as a member variable
    private Handler mHandler = new Handler();

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(icicle);
        setContentView(R.layout.splashscreen);

        // 5. Pass a new instance of StartMainActivityRunnable with reference to 'this'.
        mHandler.postDelayed(new StartMainActivityRunnable(this), SPLASH_DISPLAY_LENGTH);
    }

    // 6. Override onDestroy()
    @Override
    public void onDestroy() {
     // 7. Remove any delayed Runnable(s) and prevent them from executing.
     mHandler.removeCallbacksAndMessages(null);

     // 8. Eagerly clear mHandler allocated memory
     mHandler = null;
    }
}

After Android Marshmallow, other Productive use of Splash screen I come to think of is requesting necessary Android Permissions in your app's splash screen.

it seems like most apps handle permission request this way.

• Dialogs make bad UIX and they break the main flow and make you decide on runtime and truth is most users might not even care if your app want to write something on SD card. Some of them might not even understand what we are trying to convey until we translate it in plain english.

• Requesting permissions at one time make less number of "if else" before every operation and make your code looks clutter free.

This is a example of how you can ask for permissions in your splash activity for device running Android OS 23+ .

If all permissions are granted OR already granted OR app is running on Pre Marshmallow THEN just go and display main contents with little delay of half second so that user can appreciate effort we had put in reading this question and trying to give our best.

                .setPositiveButton("OK", okListener)
                .setNegativeButton("Cancel", null)
                .create()
                .show();
    }

    @TargetApi(Build.VERSION_CODES.M)
    private boolean addPermission(List<String> permissionsList, String permission) {

        if (checkSelfPermission(permission) != PackageManager.PERMISSION_GRANTED) {
            permissionsList.add(permission);
            // Check for Rationale Option
            if (!shouldShowRequestPermissionRationale(permission))
                return false;
        }
        return true;
    }

    /**
     * Display main content with little delay just so that user can see
     * efforts I put to make this page

    private void displaySplashScreen() {
        new Handler().postDelayed(new Runnable() {

        /*
         * Showing splash screen with a timer. This will be useful when you
         * want to show case your app logo / company
         */

            @Override
            public void run() {
                startActivity(new Intent(SplashActivity.this, AudioPlayerActivity.class));
                finish();
            }
        }, 500);
    }


}

Splash screen example :

public class MainActivity extends Activity {
    private ImageView splashImageView;
    boolean splashloading = false;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        splashImageView = new ImageView(this);
        splashImageView.setScaleType(ScaleType.FIT_XY);
        splashImageView.setImageResource(R.drawable.ic_launcher);
        setContentView(splashImageView);
        splashloading = true;
        Handler h = new Handler();
        h.postDelayed(new Runnable() {
            public void run() {
                splashloading = false;
                setContentView(R.layout.activity_main);
            }

        }, 3000);

    }

}

One way is by creating a FullScreenActivity/EmptyActivity (say SplashScreenActivity) and set it as the first Activity that shows up when you open your app. Add the following to your Activity in the AndroidManifest.xml

 <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

You can then set a handler to dismiss this activity after a few seconds.

new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                Intent i= new Intent(SplashScreenActivity.this,MainActivity.class);
                startActivity(i); //start new activity 
                finish();
            }
        }, 3000); //time in milliseconds

Secondly, if you don't wish to create a separate activity, you can inflate a layout over your MainActivity and set the layout visibility to GONE or inflate the main layout over the existing splash screen layout after a few milliseconds.

     - Add in SplashActivity 

   public class SplashActivity extends Activity {

       private ProgressBar progressBar;
       int i=0;
       Context context;
       private GoogleApiClient googleApiClient;

       @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_splash);
           context = this;

           new Handler().postDelayed(new Runnable() {
               @Override
               public void run() {
                   startActivity(new Intent(Splash.this, LoginActivity.class));
                   finish();
               }
           }, 2000);

       }

   }

  - Add in activity_splash.xml

   <RelativeLayout
   xmlns:android="http://schemas.android.com/apk/res/android"
       xmlns:tools="http://schemas.android.com/tools"
       xmlns:custom="http://schemas.android.com/apk/res-auto"
       android:background="@color/colorAccent"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       tools:context=".Splash">

       <ImageView
           android:id="@+id/ivLogo"
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           android:src="@mipmap/icon_splash"
           android:layout_centerHorizontal="true"
           android:layout_centerVertical="true"/>


       <ProgressBar
           android:id="@+id/circle_progress"
           style="?android:attr/progressBarStyleHorizontal"
           android:layout_width="fill_parent"
           android:layout_height="wrap_content"
           android:layout_alignParentBottom="true"
           android:layout_marginBottom="5dp"
           android:max="100"
           android:progressTint="@color/green"
           android:visibility="visible" />

   </RelativeLayout>

  - Add in AndroidManifest.xml

    <activity android:name="ex.com.SplashActivity">
               <intent-filter>
                   <action android:name="android.intent.action.MAIN" />

                   <category android:name="android.intent.category.LAUNCHER" />
               </intent-filter>
           </activity>

The answers above is very good, but I would like to add something else. I am new to Android, I met these problem during my development. hope this can help someone like me.

1. The Splash screen is the entry point of my app, so add the following lines in AndroidManifest.xml.

       <activity
           android:name=".SplashActivity"
           android:theme="@android:style/Theme.DeviceDefault.Light.NoActionBar">
           <intent-filter>
               <action android:name="android.intent.action.MAIN" />
               <category android:name="android.intent.category.LAUNCHER" />
           </intent-filter>
       </activity>
   

2. The splash screen should only show once in the app life cycle, I use a boolean variable to record the state of the splash screen, and only show it on the first time.

   public class SplashActivity extends Activity {
       private static boolean splashLoaded = false;
   
       @Override
       public void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
   
           if (!splashLoaded) {
               setContentView(R.layout.activity_splash);
               int secondsDelayed = 1;
               new Handler().postDelayed(new Runnable() {
                   public void run() {
                       startActivity(new Intent(SplashActivity.this, MainActivity.class));
                       finish();
                   }
               }, secondsDelayed * 500);
   
               splashLoaded = true;
           }
           else {
               Intent goToMainActivity = new Intent(SplashActivity.this, MainActivity.class);
               goToMainActivity.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
               startActivity(goToMainActivity);
               finish();
           }
       }
   }
   

happy coding!

In my case I didn't want to create a new Activity only to show a image for 2 seconds. When starting my MainAvtivity, images gets loaded into holders using picasso, I know that this takes about 1 second to load so I decided to do the following inside my MainActivity OnCreate:

splashImage = (ImageView) findViewById(R.id.spllll);

    this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

    int secondsDelayed = 1;
    new Handler().postDelayed(new Runnable() {
        public void run() {
            getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
            splashImage.setVisibility(View.GONE);

        }
    }, secondsDelayed * 2000);

When starting the application the first thing that happens is the ImageView gets displayed and the statusBar is removed by setting the window flags to full screen. Then I used a Handler to run for 2 seconds, after the 2 seconds I clear the full screen flags and set the visibility of the ImageView to GONE. Easy, simple, effective.

Here is a simple one!

Another approach is achieved by using CountDownTimer

@Override
public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.splashscreen);

 new CountDownTimer(5000, 1000) { //5 seconds
      public void onTick(long millisUntilFinished) {
          mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
      }

     public void onFinish() {
          startActivity(new Intent(SplashActivity.this, MainActivity.class));
          finish();
     }

  }.start();
}

public class SplashActivity extends Activity {

  Context ctx;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      ctx = this;
      setContentView(R.layout.activity_splash);

      Thread thread = new Thread(){
          public void run(){
              try {
                  sleep(3000);
              } catch (InterruptedException e) {
                  e.printStackTrace();
              }

              Intent in = new Intent(ctx,MainActivity.class);
              startActivity(in);
              finish();
          }
      };
      thread.start();
  }
}

The Stopping on the Splash screen for 4's 5's unnecessarily doesn't make much sense. It's Ok if you loading something in background else follow this approach to implement splash screen:- Implementing a splash screen the right way is a little different than you might imagine. The splash view that you see has to be ready immediately, even before you can inflate a layout file in your splash activity.

So you will not use a layout file. Instead, specify your splash screen’s background as the activity’s theme background. To do this, first, create an XML drawable in res/drawable.

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:drawable="@color/gray"/>

    <item>
        <bitmap
            android:gravity="center"
            android:src="@mipmap/ic_launcher"/>
    </item>

</layer-list>

Here, I’ve set up a background color and an image.

Next, you will set this as your splash activity’s background in the theme. Navigate to your styles.xml file and add a new theme for your splash activity:

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
    </style>

    <style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
        <item name="android:windowBackground">@drawable/background_splash</item>
    </style>

</resources>

In your new SplashTheme, set the window background attribute to your XML drawable. Configure this as your splash activity’s theme in your AndroidManifest.xml:

<activity
    android:name=".SplashActivity"
    android:theme="@style/SplashTheme">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

Finally, SplashActivity class should just forward you along to your main activity:

     public class SplashActivity extends AppCompatActivity {

             @Override
             protected void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);

               Intent intent = new Intent(this, MainActivity.class);
               startActivity(intent);
               finish();
    }
}

More Details read this: 1.https://www.bignerdranch.com/blog/splash-screens-the-right-way/ 2.http://blog.goodbarber.com/3-tips-to-create-a-great-splash-screen-for-your-mobile-app_a287.html

Splash screens should not be loaded from a layout file, there might still be some lag when loading it.

The best way is to create a Theme just for your SplashScreenActivity and set the android:windowBackground to a drawable ressource.

https://www.bignerdranch.com/blog/splash-screens-the-right-way/

In a nutshell:

Declare your SplashScreenActivity in the manifest:

<activity
        android:name=".activities.SplashScreenActivity"
        android:theme="@style/SplashTheme"
        android:screenOrientation="portrait">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

In your SplashScreenActivity.java:

@Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    Intent intent = new Intent(this, MainActivity_.class);
    startActivity(intent);
    finish();

}

Next create the ressource for the background window of your theme:

<style name="SplashTheme" parent="Theme.Bumpfie.Base">
    <item name="android:windowBackground">@drawable/splash</item>
</style>

Drawable file splash.xml:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@android:color/white"/>
    <item>
        <bitmap
            android:gravity="center"
            android:src="@drawable/app_logo"/>
    </item>
</layer-list>

Create a Activity, let us Activity named 'A', then create a xml file called myscreen.xml, in that set a the splash screen image as background, and then use count down timer to navigate from one Activtity to another. To know how to use Count Down timer see my answer in this question TimerTask in Android?

Abdullah's answer is great. But i want to add some more details to it with my answer.

Implementing a Splash Screen

Implementing a splash screen the right way is a little different than you might imagine. The splash view that you see has to be ready immediately, even before you can inflate a layout file in your splash activity.

So you will not use a layout file. Instead, specify your splash screen’s background as the activity’s theme background. To do this, first create an XML drawable in res/drawable.

background_splash.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:drawable="@color/gray"/>

    <item>
        <bitmap
            android:gravity="center"
            android:src="@mipmap/ic_launcher"/>
    </item>

</layer-list>

It just a layerlist with logo in center background color with it.

Now open styles.xml and add this style

<style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
        <item name="android:windowBackground">@drawable/background_splash</item>
</style>

This theme will have to actionbar and with background that we just created above.

And in manifest you need to set SplashTheme to activity that you want to use as splash.

<activity
android:name=".SplashActivity"
android:theme="@style/SplashTheme">
<intent-filter>
    <action android:name="android.intent.action.MAIN" />

    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

Then inside your activity code navigate user to the specific screen after splash using intent.

public class SplashActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Intent intent = new Intent(this, MainActivity.class);
        startActivity(intent);
        finish();
    }
}

That's the right way to do. I used these references for answer.

1. https://material.google.com/patterns/launch-screens.html
2. https://www.bignerdranch.com/blog/splash-screens-the-right-way/ Thanks to these guys for pushing me into right direction. I want to help others because accepted answer isn't a recommended to do splash screen.

• Create an activity: Splash
• Create a layout XML file: splash.xml
• Put UI components in the splash.xml layout so it looks how you want

• your Splash.java may look like this:

  public class Splash extends Activity {
      @Override
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.splash);
  
          int secondsDelayed = 1;
          new Handler().postDelayed(new Runnable() {
                  public void run() {
                          startActivity(new Intent(Splash.this, ActivityB.class));
                          finish();
                  }
          }, secondsDelayed * 1000);
      }
  }
  

• change ActivityB.class to whichever activity you want to start after the splash screen

• check your manifest file and it should look like

        <activity
            android:name=".HomeScreen"
            android:label="@string/app_name">     
        </activity>

        <activity
            android:name=".Splash"
            android:label="@string/title_activity_splash_screen">     
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

I used threads to make the Flash Screen in android.

    import android.content.Intent;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;

public class HomeScreen extends AppCompatActivity{
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.screen_home);

        Thread thread = new Thread(){
            public void run(){
                try {
                    Thread.sleep(3 * 1000);
                    Intent i = new Intent(HomeScreen.this, MainActivity.class);
                    startActivity(i);
                } catch (InterruptedException e) {
                }
            }
        };
        thread.start();
    }
}

1. Create an Activity SplashScreen.java

   public class SplashScreen extends Activity {
   protected boolean _active = true;
   protected int _splashTime = 3000; // time to display the splash screen in ms
   
   
   
   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.splashscreen);
   
       Thread splashTread = new Thread() {
           @Override
           public void run() {
               try {
                   int waited = 0;
                   while (_active && (waited < _splashTime)) {
                       sleep(100);
                       if (_active) {
                           waited += 100;
                       }
                   }
               } catch (Exception e) {
   
               } finally {
   
                   startActivity(new Intent(SplashScreen.this,
                           MainActivity.class));
                   finish();
               }
           };
                };
       splashTread.start();
   }
    }
   

2. splashscreen.xml will be like this

   <?xml version="1.0" encoding="utf-8"?>
   <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="600px" android:layout_height="1024px"
     android:background="#FF0000">
   </RelativeLayout> 
   

You can add this in your onCreate Method

new Handler().postDelayed(new Runnable() {
                @Override
                public void run() {
                    // going to next activity
                    Intent i=new Intent(SplashScreenActivity.this,MainActivity.class);
                    startActivity(i);
                    finish();
                }
            },time);

And initialize your time value in milliseconds as yo want...

private  static int time=5000;

How about a super-flexible launch screen that can use the same code and is defined in the AndroidManifest.xml, so the code will never need to change. I generally develop libraries of code and do not like customizing code because it is sloppy.

<activity
        android:name=".SplashActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        <meta-data android:name="launch_class" android:value="com.mypackage.MyFirstActivity" />
        <meta-data android:name="duration" android:value="5000" />
</activity>

Then the SpashActivity itself looks up the meta-data for "launch_class" to then make the Intent itself. The meta data "duration" defines how long the splash screen stays up.

public class SplashActivity extends Activity {

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.activity_splash);

    ComponentName componentName = new ComponentName(this, this.getClass());

    try {
        Bundle bundle = null;
        bundle = getPackageManager().getActivityInfo(componentName, PackageManager.GET_META_DATA).metaData;
        String launch_class = bundle.getString("launch_class");
        //default of 2 seconds, otherwise defined in manifest
        int duration = bundle.getInt("duration", 2000);

        if(launch_class != null) {
            try {
                final Class<?> c = Class.forName(launch_class);

                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        Intent intent = new Intent(SplashActivity.this, c);
                        startActivity(intent);
                        finish();
                    }
                }, duration);

            } catch (ClassNotFoundException e) {
                e.printStackTrace();
            }
        }
    } catch (PackageManager.NameNotFoundException e) {
        e.printStackTrace();
    }
  }
}

public class MainActivity extends Activity {

@Override

public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Thread t=new Thread()
    {

        public void run()
        {   

            try {

                sleep(2000);
                finish();
                Intent cv=new Intent(MainActivity.this,HomeScreen.class/*otherclass*/);
                startActivity(cv);
            } 

            catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    };
    t.start();
}
