GCM How do I detect if app is open and if so pop up an alert box, instead of normal notification flow?

Question

I have an app where I want to build 2 different flow\'s in:

• 1.a App is open on any activity

• 1.b App show\'s an alertbox where user can choose to go to

Answer 1

I'd just write another BroadcastReceiver like this:

public class MainActivityBroadcastReceiver extends BroadcastReceiver {

    public MainActivityBroadcastReceiver(Activity mainActivity) {

    }

    @Override
    public void onReceive(Context context, Intent intent) {
        Toast toast = Toast.makeText(context, "hola", Toast.LENGTH_LONG);
        toast.show();   
        abortBroadcast();
    }

}

and then in the MainActivity I'd override the methods and then I don't receive the notification so I intercept the `Intent~ and abort the other broadcast:

@Override
protected void onPause() {
    unregisterReceiver(mainActivityBroadcastReceiver);
    super.onPause();
}

@Override
public void onResume() {
    IntentFilter filter = new IntentFilter("com.google.android.c2dm.intent.RECEIVE");
    filter.setPriority(1);
    registerReceiver(mainActivityBroadcastReceiver, filter);

    super.onResume();
}
