Start and Stop an external app from my own app in Android

Question

My app starts others apps (upon user request) using this simple code:

Intent LaunchApp = getPackageManager().getLaunchIntentForPackage("the.external.app.package");                 
startActivity( LaunchApp );

Is there a way to finish or close that app?

I have tried with ActivityManager.killBackgroundProcesses() and with android.os.Process.sendSignal(pid, android.os.Process.SIGNAL_KILL) but no success.

The idea is to do something like this: If the app connects to the car bluetooth then it starts the music player automatically. Once the bluetooth is disconnected it should close the music player.

Thanks

Did you add the permissions to kill to your manifest? – Gabe Sechan Mar 28 '14 at 07:42 — Gabe Sechan, Mar 28 '14 at 07:42
Yes, I did "android.permission.KILL_BACKGROUND_PROCESSES" – Ton Mar 28 '14 at 07:47 — Ton, Mar 28 '14 at 07:47

You can close activity without killing process.

Use startActivityForResult() instead startActivity()

startActivityForResult( LaunchApp, 100 );// reques code = 100

Close activity by request code when you need that
```
finishActivity( 100 );
```
