안녕하세요.
미디어 플레이어로 기존 폰에서 가지고 있는 mp3 재생 샘플을 만들고 있는데 setDataSource()에서 IOException이 떨어져서 문의 드립니다.
http://developer.android.com/guide/topics/media/mediaplayer.html 를 참고해서 작성중입니다.
미디어 목록은 아래와 같은 형태로 불러오구요.
ContentResolver contentResolver = getContentResolver();
Uri uri = android.provider.MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
Cursor cursor = contentResolver.query(uri, null, null, null, null);
if (cursor == null){//
query failed, handle error.}
else if (!cursor.moveToFirst()) { // no media on the device}
lse {
int titleColumn = cursor.getColumnIndex(android.provider.MediaStore.Audio.Media.TITLE);
int idColumn = cursor.getColumnIndex(android.provider.MediaStore.Audio.Media._ID);
do {
long thisId = cursor.getLong(idColumn);
String thisTitle = cursor.getString(titleColumn);// ...process entry...
} while (cursor.moveToNext());
}
Uri contentUri = ContentUris.withAppendedId(android.provider.MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, id);
mMediaPlayer = new MediaPlayer();
mMediaPlayer.reset();
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mMediaPlayer.setDataSource(getApplicationContext(), contentUri);
그런데 setDataSource()에서 자꾸 IOException이 떨어집니다.
uri.toString()을 해보면 아래와 같이
content://media/external/audio/media/숫자 형태로 나오는걸로 보면 URI는 정상적으로 되어 있는것 같은데 말이죠..
도움좀 부탁 드려요 ㅠㅠ
