MediaPlayer Source 선택

res/raw 폴더의 music.mp3 파일을

MainActivity 에서 사용한다면

mMediaPlayer = MediaPlayer.create(MainActivity.this, r.raw.music);

File Chooser 를 통해 얻은 경로에 있는 파일을 

MainActivity 에서 사용한다면

mMediaPlayer = new MediaPlayer();

try {

mMediaPlayer.setDataSource(mFilePath);

} catch (Exception e) {
