Answer 1

i think you have to set the

recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);

i've a problem with playing the recorded sound on Windows. On my Android Smartphone i can load the recorded file und play them.

Could you jagdish play the recorded sound on Windows?

Answer 2

I have the same problem, my application writes some files and I try a web portal where it is possible to listen to these audios, for this to work I changed the enconder to AudioEncoder. AAC and it worked well for me, but the file size is much larger, if you have no problem with the file size, maybe it will work for you, too.
