RuntimeException：setDataSource失败：setDataSource（）中的status = 0xFFFFFFEA

Question

这是我的代码：

    //query external audio
    ContentResolver musicResolver = getContentResolver();

    Cursor musicCursor = musicResolver.query(musicUri, null, null, null, null);
    //iterate over results if valid
    if (musicCursor != null && musicCursor.moveToFirst()) {
        //get columns
        int titleColumn = musicCursor.getColumnIndex
                (android.provider.MediaStore.Audio.Media.TITLE);
        int idColumn = musicCursor.getColumnIndex
                (android.provider.MediaStore.Audio.Media._ID);
        int artistColumn = musicCursor.getColumnIndex
                (android.provider.MediaStore.Audio.Media.ARTIST);
        int file = musicCursor.getColumnIndex(MediaStore.Audio.Media.DATA);
        int durationTime = musicCursor.getColumnIndex(MediaStore.Audio.Media.DURATION);


        //add songs to list
        do {
            long thisId = musicCursor.getLong(idColumn);
            String thisTitle = musicCursor.getString(titleColumn);
            String thisArtist = musicCursor.getString(artistColumn);
            String thisPath = musicCursor.getString(file);
            String thisDuration = musicCursor.getString(durationTime);

            thisDuration = getTime(Long.valueOf(thisDuration));

            if (thisPath != null) {
                mmr.setDataSource(thisPath);
            }

            if (mmr.getEmbeddedPicture() != null) {
                byte[] art = mmr.getEmbeddedPicture();
                bitmap = null;
                if (art != null) {
                    bitmap = BitmapFactory.decodeByteArray(art, 0, art.length);
                } else {
                    bitmap = BitmapFactory.decodeFile(thisPath);
                }
            }


            songList.add(new Song(thisId, thisTitle, thisArtist, thisPath, thisDuration, bitmap));

        }
        while (musicCursor.moveToNext());
    }

  

引起：java.lang.RuntimeException：setDataSource failed：status =   0xFFFFFFEA               在android.media.MediaMetadataRetriever.setDataSource（本机方法）               在android.media.MediaMetadataRetriever.setDataSource（MediaMetadataRetriever.java:66）

和Uri musicUri = EXTERNAL_CONTENT_URI;
