Service Receiving Touch Events from all Activities on Phone?
<p>I've seen applications that if you touch a certain part of the screen (i.e. very top left) they will launch an application. This can be done from the home screen, or any application on my screen. The best I can figure how they can do this is by having a service that receives all touch events, and then tests whether or not they are in the specified area? How would you do this? Can anyone point me in the right direction?</p>
