That should not happen for the foreground process.

Use AlarmManager with a getActivity() PendingIntent. Or, make your activity be the home screen. I haven't tried creating a home screen that crashed, so I presume that Android relaunches a fresh copy, though I do not know for certain. > Either solution would > make the Android-device-as-electric-sign concept much more viable, as > the device needs to "just work" for months at a time without any hand- > holding from a user.
