Receiving package install and uninstall events

Question

I am trying to detect when a new App is being installed but only if my app is running. I managed to detect the installation of the app by making a BroadcastReceiver and activating it inside the AndroidManifest file but this will detect even if my app is closed. So that is why I need to manually activate and deactivate the broadcastreveiver. To do this I have this code:

br = new BroadcastReceiver() {      @Override     public void onReceive(Context context, Intent intent) {         // TODO Auto-generated method stub         Log.i("Enter", "Enters here");         Toast.makeText(context, "App Installed!!!!.", Toast.LENGTH_LONG).show();     } }; IntentFilter intentFilter = new IntentFilter(); intentFilter.addAction(Intent.ACTION_PACKAGE_ADDED); intentFilter.addAction(Intent.ACTION_PACKAGE_INSTALL); registerReceiver(br, intentFilter); 

This should make a toast when a new app is installed. But sadly it does not. It does not enter in the onReceive method. Any help is appreciated.

I tried to register the BroadcastReceiver in either manifest file or java code. But both of these two methods failed to trigger the onReceive() method. After googling this problem, I found a solution for both methods from another Thread in SO: Android Notification App

In the manifest file (this approach no longer applies since API 26 (Android 8), it was causing performance issues on earlier Android versions):

<receiver android:name=".YourReceiver">     <intent-filter>         <action android:name="android.intent.action.PACKAGE_INSTALL" />         <action android:name="android.intent.action.PACKAGE_ADDED" />         <data android:scheme="package"/>     </intent-filter> </receiver> 

In java code:

IntentFilter intentFilter = new IntentFilter(); intentFilter.addAction(Intent.ACTION_PACKAGE_ADDED); intentFilter.addAction(Intent.ACTION_PACKAGE_INSTALL); intentFilter.addDataScheme("package"); registerReceiver(br, intentFilter); 

This should work for you.
