About
This application is only usable for rooted android phones.
It is used to shut down the phone. The phone may be shut down when the widget is
pressed or when the charger is disconnected. Before shutdown a timer can be used
to delay the shutdown.
License
The program is distributed with the terms of the GNU General Public
License (GPL) version 3. As such its source might be useful as a starting
point or for taking example code snippets for other open source
applications.

Settings
The settings application can be used to control the behavior of the HaltTimer
widget.
Usage
A widget must be placed on the home screen for the application to be usable. The
main purpose of the widget is to shut down the phone a selected time after the
phone has stopped charging in projects like this
GPS tracker
Depending on your settings a timer will count down to shutdown after the widget
has been pressed or the charger has been disconnected.
Other things to consider
Unfortunately the shutdown is done in a rather brute way by doing a "reboot -p" as
root to shutdown Linux. It would be better to let all other Android applications
know about the shutdown, but unfortunately the DEVICE_POWER permission is for
system applications only and not available for ordinary applications. IMHO this
is a design flaw in Android.

To-Do
As the application works fine for my
GPS tracker project I have no plans
to add any more features.
