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

For devices targeting version >= 10+ , you need to use MediaStore api, in my case file could not be found because the file is out of my app's scoped storage.
