Broadcast receiver continue after application leave

Question

I have a problem I can not solve, the broadcast receiver of my application continues to run when I leave my application. I have to forcibly stop the application manually, whereas I are closed; Thank you for your help. Here is my manifest, and my receiver:

<?xml version="1.0" encoding="utf-8"?>

and myreceiver :

public int lock = 0;

@Override

    Bundle extra = intent.getExtras();

        if (messages.length > -1) {

            }
        }
    }
  }

Answer 1

You have MyReceiver registered in the manifest. Therefore, it is set up to receive broadcasts all the time.

If you want to only receive broadcasts some of the time, either:

• Use registerReceiver() and unregisterReceiver() on some Context, eliminating your <receiver> element from the manifest, or

• Use PackageManager and setComponentEnabledSetting() to enable or disable the <receiver> as appropriate

As an example of the former, this sample app has a fragment that registers for ACTION_BATTERY_CHANGED in onResume() and unregisters in onPause():

    super.onPause();
  }

  BroadcastReceiver onBattery=new BroadcastReceiver() {
    public void onReceive(Context context, Intent intent) {
      int pct=
          100 * intent.getIntExtra(BatteryManager.EXTRA_LEVEL, 1)
              / intent.getIntExtra(BatteryManager.EXTRA_SCALE, 1);

      bar.setProgress(pct);
      level.setText(String.valueOf(pct));

      switch (intent.getIntExtra(BatteryManager.EXTRA_STATUS, -1)) {
        case BatteryManager.BATTERY_STATUS_CHARGING:
          status.setImageResource(R.drawable.charging);
          break;

        case BatteryManager.BATTERY_STATUS_FULL:
          int plugged=
              intent.getIntExtra(BatteryManager.EXTRA_PLUGGED, -1);

          if (plugged == BatteryManager.BATTERY_PLUGGED_AC
              || plugged == BatteryManager.BATTERY_PLUGGED_USB) {
            status.setImageResource(R.drawable.full);
          }
          else {
            status.setImageResource(R.drawable.unplugged);
          }
          break;

        default:
          status.setImageResource(R.drawable.unplugged);
          break;
      }
    }
  };
}

As a result, it will only receive that broadcast while the fragment is in the foreground from an input standpoint.

Answer 2

check this and register/unregister at right place.
