Copy below code in Menifest.xml file

  <receiver
    android:name="com.example.extraApp.InstallReceiver"
    android:exported="true">
    <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>

Creat new java class copy below code in it

public class InstallReceiver extends BroadcastReceiver{    
@Override
public void onReceive(Context context, Intent intent) {
    try {
        Intent new_intent = context.getPackageManager().getLaunchIntentForPackage("com.example.updaterjschtest");
        context.startActivity(new_intent);
    } catch (Exception e) {
        e.printStackTrace();
    }   
}

}
