How to Programatically Dial a Phone number in the Android SDK?

How do you programatically do this in the Android SDK:

1. Dial a pho开发者_开发技巧ne number
2. Bypass the keypad screen
3. Send additional DTMF after the number is dialed
4. Bypass the send DTMF tone prompt

I have managed to do 1 till 3 by dialing +555-1212w1234 but I am wondering if anyone knows how to bypass the send DTMF tone prompt.

You cannot inject DTMF codes into the call audio stream at this time. There are some proposals being discussed now for adding this capability to Android.

Sorry!

Your #4 is not doable. The best you can do is 1 to 3. I use comma (,) for 2 second pause, and add more commas if needed.
