The app crashed everytime, I don't know exacty where is the probelm.

startRecord.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            ContentValues values1 = new ContentValues();
            values1.put(MediaStore.Audio.Media.DISPLAY_NAME, "My Song.mp3");
            ContentResolver resolver = getApplicationContext().getContentResolver();
            Uri uri = resolver.insert(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, values1);
        }
    });

this is the error
