Sometimes I look at the Devices window in Eclipse.
Then I select my app. And, I press the stop sign button to kill it.
Then, for some reason, it starts up again on its own a second later.
Anyone know exactly what causes this strange restarting?

Yep, it's an override :)
Note that you can't do a 'startActivity*ForResult*' on a regular Context.
For that, you need an Activity.
