play an audio file on a voice call
<p>I have a rather tricky question this time.<br>
I want to know how to Inject audio to microphone source during a call.<br>
I know I have read dozens of topics here and there that states "it's not possible", "don't bother" etc..<br>
But there are many things made impossible for us dev's by Android staff and we always managed to come up with a work-around-it.<br>
For example, this time the easiest solution would be to play the audio via speaker with max volume, do a noise cancellation and hope for the best. ;)</p>
