Arranging for Android service to start again after phone restarts

Question

i need a service in my app that starts first time and runs forever, even if user restart his phone, my service starts automatically without running my app. i write this code but when user restart his phone, my service doesn't start again!!

public class notifService extends Service {
    @Override
    public IBinder onBind(Intent arg0) {
        return null;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        super.onStart(intent, startId);
        return Service.START_STICKY;
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
    }
}

and in the main activity i start service like this:

// start service
Intent service = new Intent(MainActivity.this, notifService.class);
MainActivity.this.startService(service);

thanks for you help.

Answer 1

Listen for android.intent.action.BOOT_COMPLETED in BroadcastReceiver and start your service.

For example

public class YourDefinedBootReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Intent service = new Intent(context, notifService.class);
    context.startService(service);
    }
}

Also, you must hold the permission:

• RECEIVE_BOOT_COMPLETED
