[android] How to check programmatically if an application is installed or not in Android?

We have installed applications programmatically.

  1. If the application is already installed in the device the application is open automatically.
  2. Otherwise install the particular application.

Guide Me. I have no idea. Thanks.

This question is related to android apk

The answer is


Try with this:

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

        // Add respective layout
        setContentView(R.layout.main_activity);

        // Use package name which we want to check
        boolean isAppInstalled = appInstalledOrNot("com.check.application");  

        if(isAppInstalled) {
            //This intent will help you to launch if the package is already installed
            Intent LaunchIntent = getPackageManager()
                .getLaunchIntentForPackage("com.check.application");
            startActivity(LaunchIntent);

            Log.i("Application is already installed.");       
        } else {
            // Do whatever we want to do if application not installed
            // For example, Redirect to play store

            Log.i("Application is not currently installed.");
        }
    }

    private boolean appInstalledOrNot(String uri) {
        PackageManager pm = getPackageManager();
        try {
            pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
            return true;
        } catch (PackageManager.NameNotFoundException e) {
        }

        return false;
    }

}

Check App is installed or not in Android by using kotlin.

Creating kotlin extension.

fun PackageManager.isAppInstalled(packageName: String): Boolean = try {
        getApplicationInfo(packageName, PackageManager.GET_META_DATA)
        true
    } catch (e: Exception) {
        false
    }

Now, can check if app is install or not

if (packageManager.isAppInstalled("AppPackageName")) {
    // App is installed
}else{
    // App is not installed
}

If you know the package name, then this works without using a try-catch block or iterating through a bunch of packages:

public static boolean isPackageInstalled(Context context, String packageName) {
    final PackageManager packageManager = context.getPackageManager();
    Intent intent = packageManager.getLaunchIntentForPackage(packageName);
    if (intent == null) {
        return false;
    }
    List<ResolveInfo> list = packageManager.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
    return !list.isEmpty();
}

A cool answer to other problems. If you do not want to differentiate "com.myapp.debug" and "com.myapp.release" for example !

public static boolean isAppInstalled(final Context context, final String packageName) {
    final List<ApplicationInfo> appsInfo = context.getPackageManager().getInstalledApplications(0);
    for (final ApplicationInfo appInfo : appsInfo) {
        if (appInfo.packageName.contains(packageName)) return true;
    }
    return false;
}

Try this

This code is used to check weather your application with package name is installed or not if not then it will open playstore link of your app otherwise your installed app

String your_apppackagename="com.app.testing";
    PackageManager packageManager = getPackageManager();
    ApplicationInfo applicationInfo = null;
    try {
        applicationInfo = packageManager.getApplicationInfo(your_apppackagename, 0);
    } catch (PackageManager.NameNotFoundException e) {
        e.printStackTrace();
    }
    if (applicationInfo == null) {
        // not installed it will open your app directly on playstore
        startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=" + your_apppackagename)));
    } else {
        // Installed
        Intent LaunchIntent = packageManager.getLaunchIntentForPackage(your_apppackagename);
        startActivity( LaunchIntent );
    }

Cleaner solution (without try-catch) than the accepted answer (based on AndroidRate Library):

public static boolean isPackageExists(@NonNull final Context context, @NonNull final String targetPackage) {
    List<ApplicationInfo> packages = context.getPackageManager().getInstalledApplications(0);
    for (ApplicationInfo packageInfo : packages) {
        if (targetPackage.equals(packageInfo.packageName)) {
            return true;
        }
    }
    return false;
}

You can do it using Kotlin extensions :

fun Context.getInstalledPackages(): List<String> {
    val packagesList = mutableListOf<String>()
    packageManager.getInstalledPackages(0).forEach {
        if ( it.applicationInfo.sourceDir.startsWith("/data/app/") && it.versionName != null)
            packagesList.add(it.packageName)
    }
    return packagesList
}

fun Context.isInDevice(packageName: String): Boolean {
    return getInstalledPackages().contains(packageName)
}

@Egemen Hamutçu s answer in kotlin B-)

    private fun isAppInstalled(context: Context, uri: String): Boolean {
        val packageInfoList = context.packageManager.getInstalledPackages(PackageManager.GET_ACTIVITIES)
        return packageInfoList.asSequence().filter { it?.packageName == uri }.any()
    }

This code checks to make sure the app is installed, but also checks to make sure it's enabled.

private boolean isAppInstalled(String packageName) {
    PackageManager pm = getPackageManager();
    try {
        pm.getPackageInfo(packageName, PackageManager.GET_ACTIVITIES);
        return pm.getApplicationInfo(packageName, 0).enabled;
    }
    catch (PackageManager.NameNotFoundException e) {
        e.printStackTrace();
        return false;
    }
}

The above code didn't work for me. The following approach worked.

Create an Intent object with appropriate info and then check if the Intent is callable or not using the following function:

private boolean isCallable(Intent intent) {  
        List<ResolveInfo> list = getPackageManager().queryIntentActivities(intent,   
        PackageManager.MATCH_DEFAULT_ONLY);  
        return list.size() > 0;  
}

I think using try/catch pattern is not very well for performance. I advice to use this:

public static boolean appInstalledOrNot(Context context, String uri) {
    PackageManager pm = context.getPackageManager();
    List<PackageInfo> packageInfoList = pm.getInstalledPackages(PackageManager.GET_ACTIVITIES);
    if (packageInfoList != null) {
        for (PackageInfo packageInfo : packageInfoList) {
            String packageName = packageInfo.packageName;
            if (packageName != null && packageName.equals(uri)) {
                return true;
            }
        }
    }
    return false;
}

A simpler implementation using Kotlin

fun PackageManager.isAppInstalled(packageName: String): Boolean =
        getInstalledApplications(PackageManager.GET_META_DATA)
                .firstOrNull { it.packageName == packageName } != null

And call it like this (seeking for Spotify app):

packageManager.isAppInstalled("com.spotify.music")

Somewhat cleaner solution than the accepted answer (based on this question):

public static boolean isAppInstalled(Context context, String packageName) {
    try {
        context.getPackageManager().getApplicationInfo(packageName, 0);
        return true;
    }
    catch (PackageManager.NameNotFoundException e) {
        return false;
    }
}

I chose to put it in a helper class as a static utility. Usage example:

boolean whatsappFound = AndroidUtils.isAppInstalled(context, "com.whatsapp");

This answer shows how to get the app from the Play Store if the app is missing, though care needs to be taken on devices that don't have the Play Store.


All the answers only check certain app is installed or not. But, as we all know an app can be installed but disabled by the user, unusable.

Therefore, this solution checks for both. i.e, installed AND enabled apps.

public static boolean isPackageInstalled(String packageName, PackageManager packageManager) {
     try {
          return packageManager.getApplicationInfo(packageName, 0).enabled;
     }
     catch (PackageManager.NameNotFoundException e) {
          return false;
     }
}

Call the method isPackageInstalled():

boolean isAppInstalled = isPackageInstalled("com.android.app" , this.getPackageManager());

Now, use the boolean variable isAppInstalled and do whatever you want.

if(isAppInstalled ) {
    /* do whatever you want */
}

So nicer with Kotlin suger:

  private fun isSomePackageInstalled(context: Context, packageName: String): Boolean {

    val packageManager = context.packageManager

    return runCatching { packageManager.getPackageInfo(packageName, 0) }.isSuccess
  }
