Android making a fullscreen application

Question

What is the simplest change that I can make to a new Blank Activity  as created by the latest version of Android Studio  to get the app to appear fullscreen   I want to create a fullscreen Android application  I m working with Android Studio  This post suggests that I add a line such as      android theme   android style Theme Holo Light NoActionBar Fullscreen       to the AndroidManifest xml file  as shown below        lt  xml version  1 0  encoding  utf-8   gt       lt manifest xmlns android  http   schemas android com apk res android              package  com lexogram james blackslate   gt                lt application                     android allowBackup  true                      android icon   drawable ic launcher                      android label   string app name                      android theme   style AppTheme   gt                       lt activity                             android name  com lexogram james blackslate MainActivity                              android label   string app name                              android theme   android style Theme Holo Light NoActionBar Fullscreen  gt                               lt intent-filter gt                                       lt action android name  android intent action MAIN    gt                                        lt category android name  android intent category LAUNCHER    gt                               lt  intent-filter gt                       lt  activity gt               lt  application gt        lt  manifest gt    When I do this  the app compiles but it crashes on launch  If I remove the line  the app runs fine  but with the action bar and a title bar  as also noted by other users   This is my first attempt at creating an Android app  so my app is hardly altered from the original Hello World example   EDIT  I created a new project  and made just this one change to it  Here is an extract from the error log   FATAL EXCEPTION  main     java lang RuntimeException  Unable to start activity ComponentInfo com lexogram james test com lexogram james test MainActivity   java lang IllegalStateException  You need to use a Theme AppCompat theme  or descendant  with this activity          at android app ActivityThread performLaunchActivity ActivityThread java 2669       NOTE  I am testing on a old Samsung SGH-T499Y  running Android 2 2  Froyo

You can use the following codes to have a full page in android

Step 1 : Make theme in styles.xml section

<style name="AppTheme.Fullscreen" parent="AppTheme">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

Step 2 : Add theme on AndroidManifest.xml

<activity
android:name=“.Activity”
android:theme="@style/AppTheme.Fullscreen"/>

Step 3 : Java codes section

For example you can added following codes in to the onCreate() method.

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

Simply declare in styles xml     lt style name  AppTheme Fullscreen  parent  AppTheme  gt       lt item name  windowActionBar  gt false lt  item gt       lt item name  windowNoTitle  gt true lt  item gt       lt item name  android windowFullscreen  gt true lt  item gt     lt  style gt    Then use in menifest xml       lt activity         android name   activities Splash          android theme   style AppTheme Fullscreen  gt           lt intent-filter gt               lt action android name  android intent action MAIN    gt                lt category android name  android intent category LAUNCHER    gt           lt  intent-filter gt       lt  activity gt    Chill Pill

I recently had the exact same issue and benefitted from the following post as well  in addition to Rohit5k2 s solution above    https   bsgconsultancy wordpress com 2015 09 13 convert-any-website-into-android-application-by-using-android-studio   In Step 3  MainActivity extends Activity instead of ActionBarActivity  as Rohit5k2 mentioned   Putting the NoTitleBar and Fullscreen theme elements into the correct places in the AndroidManifest xml file is also very important  take a look at Step 4

in my case all works fine  See in logcat   Maybe logcat show something that can help you to resolve your problem   Anyway you can try do it programmatically    public class ActivityName extends Activity            Override         public void onCreate Bundle savedInstanceState                super onCreate savedInstanceState                  remove title             requestWindowFeature Window FEATURE NO TITLE               getWindow   setFlags WindowManager LayoutParams FLAG FULLSCREEN              WindowManager LayoutParams FLAG FULLSCREEN               setContentView R layout main

Update Answer I added android windowIsTranslucent in case you have white screen in start of activity    just create new Style in values styles xml   lt  xml version  1 0  encoding  utf-8   gt   lt resources gt        lt style name  AppTheme  parent  Theme AppCompat NoActionBar  gt       lt  -- to hide white screen in start of window -- gt       lt item name  android windowIsTranslucent  gt true lt  item gt       lt  style gt    lt  resources gt    from your AndroidManifest xml add style to your activity   android theme   style AppTheme   to be like this   lt activity android name   Splash              android theme   style AppTheme  gt               lt intent-filter gt                   lt action android name  android intent action MAIN    gt                   lt category android name  android intent category LAUNCHER    gt               lt  intent-filter gt           lt  activity gt

You are getting this problem because the activity you are trying to apply the android theme   android style Theme Holo Light NoActionBar Fullscreen  gt  to is extending ActionBarActivity which requires the AppCompat theme to be applied   Extend your activity from Activity rather than from ActionBarActivity  You might have to change your Java class accordingly little bit   If you want to remove status bar too then use this before setContentView layout  in onCreateView method          getWindow   setFlags WindowManager LayoutParams FLAG FULLSCREEN          WindowManager LayoutParams FLAG FULLSCREEN

If you Checkout the current Android Studio  You could create a New Activity with the Full-screen template  If you Create such an Activity  You could look into the basic code that Android Studio uses to switch between full-screen and normal mode     This is the code I found in there  With some minor tweaks I m sure you ll get what you need   public class FullscreenActivity extends AppCompatActivity       private static final boolean AUTO HIDE   true      private static final int AUTO HIDE DELAY MILLIS   3000      private static final int UI ANIMATION DELAY   300      private

 public void run                    Delayed removal of status and navigation bar                 Note that some of these constants are new as of API 16  Jelly Bean                 and API 19  KitKat   It is safe to use them  as they are inlined                at compile-time and do nothing on earlier devices              mContentView setSystemUiVisibility View SYSTEM UI FLAG LOW PROFILE                       View SYSTEM UI FLAG FULLSCREEN                       View SYSTEM UI FLAG LAYOUT STABLE                       View SYSTEM UI FLAG IMMERSIVE STICKY                       View SYSTEM UI FLAG

     Override         public void run                    Delayed display of UI elements             ActionBar actionBar   getSupportActionBar                if  actionBar    null                    actionBar show                              mControlsView setVisibility View VISIBLE                        private boolean mVisible      private final Runnable mHideRunnable   new Runnable              Override         public void run                 hide                         private final View OnTouchListener mDelayHideTouchListener   new View OnTouchListener              Override         public boolean onTouch View view  MotionEvent motionEvent                if  AUTO HIDE                    delayedHide AUTO HIDE DELAY MILLIS                             return false                        Override     protected void onCreate Bundle savedInstanceState            super onCreate savedInstanceState            setContentView R layout activity fullscreen            mVisible   true          mControlsView   findViewById R id fullscreen content controls           mContentView   findViewById R id fullscreen content                Set up the user interaction to manually show or hide the

          Upon interacting with UI controls  delay any scheduled hide              operations to prevent the jarring behavior of controls going away            while interacting with the UI          findViewById R id dummy button  setOnTouchListener mDelayHideTouchListener              Override     protected void onPostCreate Bundle savedInstanceState            super onPostCreate savedInstanceState               Trigger the initial hide   shortly after the activity has been            created  to briefly hint to the user that UI controls            are available          delayedHide 100             private void toggle             if  mVisible                hide              else               show                        private void hide                Hide UI first         ActionBar actionBar   getSupportActionBar            if  actionBar    null                actionBar hide                      mControlsView setVisibility View GONE           mVisible   false              Schedule a runnable to remove the status and navigation bar after a delay         mHideHandler removeCallbacks mShowPart2Runnable           mHideHandler postDelayed mHidePart2Runnable  UI ANIMATION DELAY              SuppressLint  InlinedApi       private void show                Show the system bar         mContentView setSystemUiVisibility View SYSTEM UI FLAG LAYOUT FULLSCREEN

         mHideHandler postDelayed mHideRunnable  delayMillis             Now I went further to checkout how this could be done in a more simple fashion  Making changes to the AppTheme style in your styles xml file would be most helpful  This changes all your activities to a Full Screen view    lt item name  windowActionBar  gt false lt  item gt   lt item name  windowNoTitle  gt true lt  item gt   lt item name  android windowFullscreen  gt true lt  item gt    If you want only some activities to look Full Screen  you could create a new AppTheme that extends your current app theme and include the above code in that new style that you created  This way  you just have to set style yournewapptheme in the manifest of whichever activity you want to go Full Screen
