Android keep BroadcastReceiver in background

Question

I created a BroadcastReceiver and it runs only when my app shown in recent apps menu. If I remove my app from the recent apps the BroadcastReceiver will stop working. How ca

Answer 1

Use a service with it. Services can survive when the app dies if they have the right flag example:

public class MyService extends Service {
    public int onStartCommand(Intent intent, int flags, int startId) {
        return START_STICKY; //this defines this service to stay alive
    }
@Override
public void onCreate() {
    super.onCreate();

    appStatus = APPISUP;

    //This is a thread that stays alive for as long as you need
    new CheckActivityStatus().execute();
    //Not needed but in case you wish to lauch other apps from it
}

private class CheckActivityStatus extends AsyncTask {
 @Override
    protected String doInBackground(String... params) {
        while(true) {
        ... //add something that breaks eventually
        }
    }
 }

To lauch the service you have to lauch it from an activity like so:

Intent service = new Intent(getBaseContext(), MyService.class);
    startService(service);

With the service the BroadcastReceiver still functions receiving whatever you want. Note that the service sometimes stops and comes back. I haven't found out why but I'm betting on priorities of other apps that may ask the system to halt the service
