Hi, I am looking for Delphi examples on waking up an application when an Android device is in sleep mode. Setting an alarm with the AlarmManager TAndroidHelper.AlarmManager.&set(TJAlarmManager.JavaClass.RTC_WAKEUP,...) fires MyAppEvent on time, it writes a message in the Memo, but the app does NOT wake up. function TfrMain.MyAppEvent(aAppEvent: TApplicationEvent; AContext: TObject): Boolean; begin result := False; case aAppEvent of TApplicationEvent.BecameActive: memo1.Lines.Add('BecameActive'); ... Only when I manually wake up the device, I see the app appear on screen. How can wake up the device when MyAppEvent notifies the event of becoming active? Even more, the app should become on the front of other running applications in the case the device is not asleep. I've searched already on the possibilities of the AlarmManager and the PowerManager, but found nothing to wake up while being asleep. Any example would be appreciated!
