ContentValues values = new ContentValues();
values.put(MediaStore.Audio.Media.MIME_TYPE, "audio/mp3");
Uri newUri = mContext.getContentResolver().insert(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, values);

 

이렇게 하면 타입이 mp3인 파일만 검색해서 uri를 가져오는게 아닌가요?

Uri newUri = mContext.getContentResolver().insert(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, values);

이 부분에서 에러가 나네요, 도와주세요~~~
