use runOnUiThread for mediaRecorder prepare.

private boolean prepareMediaRecorder() {

    mediaRecorder = new MediaRecorder();

    runOnUiThread(new Runnable() {
        @Override
        public void run() {

            mediaRecorder.reset();
            mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);

            mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.AMR_NB);

            mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);

            mediaRecorder.setOutputFile(filePath);

            try {
                mediaRecorder.prepare();
            } catch (IOException e) {
                mediaRecorder = null;
                return;
            }
            mediaRecorder.start();
            recording = true;
        }
    });

    return true;
}
