here is my

public class Receiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    // Check if the application is install or uninstall and display the message accordingly
    if (intent.getAction().equals("android.intent.action.PACKAGE_ADDED")) {
        // Application Install
        Log.e("Package Added:-", intent.getData().toString());

    } else if (intent.getAction().equals("android.intent.action.PACKAGE_REMOVED")) {

        Log.e("Package Removed:-", intent.getData().toString());

Register the broadcast in onResume of your wanted activity, unregister it in onPause of the same activity. See the official doc for more info — An-droid, Apr 22 '16 at 09:39

For example :

@Override
protected void onPause () {

    // Unregister since the activity is not visible
    LocalBroadcastManager.getInstance(this).unregisterReceiver(mReceiver);
    super.onPause();
}

@Override
protected void onResume () {
    super.onResume();

    // Register mMessageReceiver to receive messages.
    LocalBroadcastManager.getInstance(this).registerReceiver(mReceiver,
                                                             new IntentFilter(
                                                                     YourBroadcastReceiver.class
                                                                             .getSimpleName()));
}
