Android Media Recorder start failed exception

Question

I am having problem with media recorder in android. I am recording an audio which works well with LG P500 but the same code is not working on Samsung GT - S5360. I am getting error as start failed -22.

This is the code I am using:

final MediaRecorder recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.VOICE_CALL‌​);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GP‌​P);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(path);
try {
    recorder.prepare();
    recorder.start();
} catch (Exception e) { Log.d(TAG, "Exception : " + e); }

When debugging got cause as null in logcat.

Please suggest me some solution.

Answer 1

I had the same issue, and I tried installing a voice recorder from the play store to check. It didn't allow me to record VOICE_CALL too. From that I realised some device manufacturers don't support this. So record with the MIC if the device doesn't support VOICE_CALL.

Answer 2

The permission suggested by the op did not work for me, probably because it does not exist:)

If you are getting this error check the way you are setting up the media recorder. In my case it only failed in some devices as well. I was doing this for all devices running Os version > API 10:

mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.AMR_WB);       
mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_WB);

Turns out that the faulting device was running JB but didn't support wideband, so changing it to raw/narrowband worked:

mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.RAW_AMR);      
mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);

Answer 3

Based on the comment of the actual poster... he suggested his answer in the comment. Putting this into an actual answer, hoping that it helps others:

The OP added the following permission and his code worked well for him:

<uses-permission android:name="android.permission.STORAGE" />
