Android Question stop dialing

[mash4aa]

How to stop dialing after 3 seconds when I use
StartActivity(pc.Call("xxxxxxxxx"))

simulation does not work
keyg.keygenerator(KeyCodes.KEYCODE_ENDCALL)

When executing StartActivity you´ll leave your app and starting another app which does to call. Your app is sleeping.
You dont have control over the android.phone app and you cannot send any keycodes to it; reminder: your app is sleeping.

and if it is otherwise, other than the command to dialing
StartActivity (pc.Call ("xxxxxxxxx"))
