Initiate a private phone call for both side in Android app

According to the platform source-code there is NO WAY to place a call without the knowledge of the user. The best thing you can do is to make the call automatically but the user will see a dialog saying: “Calling XXXXXXXX” and he will have the chance to cancel it.

Even if you make your own dialer application you will have to sign it with the system key and place it in the system/apps folder in order to get the required permissions for that kind of things.

As for the call log, I don’t know if you can make the call not to appear in it in the first place but I think (not sure though) that you can find it and deleted afterwards. Android informs other applications of call actions via Intents so it is relative easy to detect when a call ended and then query the call log.

Hope this helps…
