[android-developers] How to detect the task initiated by touching a button in the kernel?

Hi all,

As we know, in a application, when we click a button, a corresponding
task will be initialized in the kernel. I guess the mechanism is that:
when we click button, a GUI event will be generated and a message will
be sent to the application and the corresponding task will be
initialized. Can someone has some ideas about how to detect this kind
of interactive task in the kernel? Thank you very much.

Best regards,
Lason
