查询MediaStore.Video.Media.EXTERNAL_CONTENT_URI仅返回视频/sdcard/DCIM/100MEDIA

但我想在我的/sdcard/Android/data/mypackage/files文件夹中获取视频缩略图.可能吗 ？

这是我的代码的一部分:

        ContentResolver cr = getContentResolver();
    String[] proj = {
                    BaseColumns._ID
    };

    Cursor c = cr.query(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, proj, null, null, null);
    if (c.moveToFirst()) {
        do
        {
            int id = c.getInt(0);
            Bitmap b = MediaStore.Video.Thumbnails.getThumbnail(cr, id, MediaStore.Video.Thumbnails.MINI_KIND, null);
            Log.d("*****My Thumbnail*****", "onCreate bitmap " + b);
            ImageView iv = (ImageView) findViewById(R.id.img_thumbnail);
            iv.setImageBitmap(b);
        }
        while( c.moveToNext() );
    }         
    c.close();
