Question

我拥有一部没有任何SD卡插槽的手机，但它有64GB的内部存储空间。问题是每当我使用我的自定义媒体播放器加载歌曲时，它只加载.ogg个文件（根本没有MP3文件），这发生在uri = MediaStore.Audio.Media.INTERNAL_CONTENT_URI;时。但是当uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;崩溃应用程序时，因为没有要搜索的SD卡槽。

这是我的代码，

    private void loadSongs() {
    Uri uri = MediaStore.Audio.Media.INTERNAL_CONTENT_URI;
    //Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;

    String selection = MediaStore.Audio.Media.IS_MUSIC + "!=0";
    Cursor cursor = getContentResolver().query(uri, null, selection, null, null);
    if (cursor != null) {
        if (cursor.moveToFirst()) {
            do {
                String name = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DISPLAY_NAME));
                String artist = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.ARTIST));
                String url = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DATA));

                Log.i("DATA111", url);

                mediaMetadataRetrieve = new MediaMetadataRetriever();
                mediaMetadataRetrieve.setDataSource(url);

                art = mediaMetadataRetrieve.getEmbeddedPicture();

                if (art != null) {
                    songImage = BitmapFactory.decodeByteArray(art, 0, art.length);
                }

                SongInfo s = new SongInfo(name, artist, url, songImage);
                _songs.add(s);

            } while (cursor.moveToNext());
        }

        cursor.close();
        songAdapter = new SongAdapter(MainActivity.this, _songs);

    }
}

有人能找到我解决这个问题的方法吗？

Logcats结果：

运行结果：

这是Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;：

当它是Uri uri = MediaStore.Audio.Media.INTERNAL_CONTENT_URI;时，它会显示I/DATA111: /system/media/audio/ui/Effect_Tick.ogg E/MediaMetadataRetrieverJNI: getEmbeddedPicture: Call to getEmbeddedPicture failed.和许多其他.ogg文件。
