Play audio into a phone call on Android in 2.3+
Is it possible to play audio into a phone call on Android in 2.3+? For instance, I'd like to play an MP3 into a call that was placed from the device (not record the audio).
I've seen people ask about earlier vers开发者_C百科ions of Android and the responses are generally along the lines of "when the hardware supports it, the software will".
So, do the newer Android devices/SDKs support this sort of audio routing?
It's not possible, sorry. As far as I know the only way to do that is to output the audio via speaker so it would be caught by microphone.
