Getting touch event in any view (Android)

I need to make a service that capture all touch events, not in a specific view or when an specific activity is open. This service is started when the boot is completed (and I have an app to stop/play this service when I want it). So it write something (in a Toast) when the user touch any place in the screen.

Can I do this? Or only in specifics things (with OnTouchListener and adding specifics views, for e开发者_运维知识库xample)?

Sorry for my bad english. thanks

If you override the View itself and build your own ROM, you will be able to have these kind of things. So, straight answer will be just no. Sorry.
