The default behavior of the back key is to exit your activity by calling finish() (which should pop to the next activity in the activity stack of the task your activity was in, or to another task if your activity was at the bottom of its task). You can override that.
The behavior of the home key is to switch to the home application, but your activity doesn't exit.
