如何在使用onStop（）关闭应用程序后运行任务？

Question

I am currently experimenting with Android I was wondering how i can make postDelayed run after I hit the home button?

Using handler I am able to make the postDelayed run every minute so that a integer is increased by one, but I want the integer to keep increasing even after I leave the app by pressing the home button.

Is there solution to my problem?

You can use AlarmManeger to start your Service in a specific time. Here is an example with NotificationService :

Log.i(TAG, "Setting intent");
Intent intent = new Intent(context, NotificationService.class);

Log.i(TAG, "Setting pendingIntent");
PendingIntent pendingIntent = PendingIntent.getService(context, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);

Log.i(TAG, "Setting alarm");
alarmManager.set(AlarmManager.RTC_WAKEUP, time.getMillis(), pendingIntent);
