A few days ago, I came to know about apps such as Tasker and Locale. Today, I have purchased the Tasker app from Google Play. I have spent around more than an hour, going around and exploring the app.
I didn't find any option that would reconfigure/reprogram the volume-up and down buttons (whereas camera button can be). Instead of having various different gestures and shakes to trigger/change/alter/start something, it would be lot more easeir to just press the volume up and down buttons (or may be even different binary combinations of these two buttons).
My question is: Does Android Api has any provision for this at all? If Yes, which app implements this option? If No, why not?
