Ruslan 5 Posted May 20 (edited) I need to open application periodically every minute. For testing I have a simple application with just this code that should open the application: function getTimeAfterInSecs(Seconds: Integer): Int64; var Calendar: JCalendar; begin Calendar := TJCalendar.JavaClass.getInstance; Calendar.add(TJCalendar.JavaClass.SECOND, Seconds); Result := Calendar.getTimeInMillis; end; procedure TForm2.Button1Click(Sender: TObject); var Intent: JIntent; PendingIntent: JPendingIntent; LFlags: Integer; begin Intent := TJIntent.Create; Intent.setClassName(TAndroidHelper.Context, StringToJString('com.embarcadero.firemonkey.FMXNativeActivity')); LFlags := TJPendingIntent.JavaClass.FLAG_UPDATE_CURRENT or TJPendingIntent.JavaClass.FLAG_IMMUTABLE; PendingIntent := TJPendingIntent.JavaClass.getActivity(TAndroidHelper.Context, 1, Intent, LFlags); TAndroidHelper.AlarmManager.&set(TJAlarmManager.JavaClass.RTC_WAKEUP, getTimeAfterInSecs(60), PendingIntent); end; procedure TForm2.Button2Click(Sender: TObject); var Intent: JIntent; PendingIntent: JPendingIntent; LFlags: Integer; AlarmManager: JAlarmManager; begin Intent := TJIntent.Create; Intent.setClassName(TAndroidHelper.Context, StringToJString('com.embarcadero.firemonkey.FMXNativeActivity')); LFlags := TJPendingIntent.JavaClass.FLAG_UPDATE_CURRENT or TJPendingIntent.JavaClass.FLAG_IMMUTABLE; PendingIntent := TJPendingIntent.JavaClass.getActivity(TAndroidHelper.Context, 0, Intent, LFlags); AlarmManager := TJAlarmManager.Wrap(TAndroidHelper.Context.getSystemService(TJContext.JavaClass.ALARM_SERVICE)); AlarmManager.setExactAndAllowWhileIdle(TJAlarmManager.JavaClass.RTC_WAKEUP, getTimeAfterInSecs(60), PendingIntent); end; Unfortunately the application does not open. What am I doing wrong? Edited May 20 by Ruslan Share this post Link to post

It could be this: https://developer.android.com/about/versions/14/changes/schedule-exact-alarms ..and/or it could be this: https://developer.android.com/guide/components/activities/background-starts Using a logcat viewer to check what messages are emitted by the system would help diagnose the problem.
