Q1: Why we don't have task killer feature?

A1: Since we know about how android device works, and we even investigate the way of task killer work before, we can't add this feature because it violate our policy. When killing a service using task killer, android system would always automatically restart that service, then task killer will try to terminate that service again, just like a never-ending cat mouse game. Also, restart a service in most case will use more battery than leaving it run in the background, the only way to safely stop a service is using the android built in Force Stop feature.
