Change device status to offline right away when app is put to background

Currently it takes some time (~+30 seconds) before Status of the Android device changes from Online to Offline in DS Device Manager, when app is put to background on the device.

During that time, user can try to run the project on the device. Eventually sending is stopped and device status is offline, as expected.

It would be nice if the status of the device would change right away to offline when app is put to background, just like it does when app is completely closed on the device.
