MediaRecorder IOException: prepare failed

Question

I want to use MediaRecorder to record voice, my code is:

 public void record(View v) {
       Log.d(TAG, \"record\");

    this.mediaRecorder.setAudioChannel         


        

Answer 1

First at all you code looks fine. Have you added the required permissions to your manifest file?

If yes, then try replacing:

this.mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);

by

this.mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);

Don't forget to check if the path of your video file is correct.
