stop the widget from running in the background, on delete()

问题

Hey, Anyone knows how to kill widget on delete(). When i delete the widget its stays running in the background,it never dies unless i foreclose the whole app. My app consists of 4 activities and the widget is not the main activity and im using thread instead of service for the appwidget.

All what i need is stop the widget from running in the background when i delete it. i've tried using system.exit(0). It didn't work, all what it does is clear all the data in the widget. Or if i can kill the app ondelete();

Any ideas? I'd really appreciated.

That is the normal behavior. The process is kept around in case the app needs to run again. This saves work, since it can probably just be re-used the next time the widget needs to update or the user launches the app.
