在指定的时间段后返回活动

Question

I would like to return to specified Activity from each other Activity after specified period of idle time. What should I use: Service , AlarmManager or maybe something else?

Answer 1

If you just want this to work only for your activities (not from background etc.) just use TimerTask in every activity of yours (well, in a superclass to avoid duplication). There's no point in putting up a Service for that.

Answer 2

使用Pending Intent，请参阅此链接... http://developer.android.com/reference/android/app/PendingIntent.html

Answer 3

Instead of using a service, or alarmmanager, you can use timertask, or i would suggest handler. Handler.postdelayed. Its a better option.
