I have a question with android apps.

"How to kill an android app from task manager?". I have tried `System.exit(0)`, `android.os.Process.killProcess(android.os.Process.myPid());` and `finish()` but they only stop app and don't kill app from task manager. Please tell me how to do that.

**UPDATED:**
I used `finishAffinity()` to clear app from task manager and `System.exit(0)` to stop activity, it looks like fine for my problem.
