Question

I m trying to include the Album Art out of a mp3 file into my application, but it says: Call to getEmbeddedPicture failed.

在我的Song类中,我确定了每一歌的艺术作品:

metaDataRetriver = new MediaMetadataRetriever();
metaDataRetriver.setDataSource(path);
//path = /mnt/sdcard/chan_mp3/Titel.mp3
byte[] artwork = metaDataRetriver.getEmbeddedPicture();

在我的习俗Adapter中,我试图展示:

// This code works perfectly fine: for each song I get artist and title
textView.setText(values.get(position).getArtist() + " - " + values.get(position).getTitle());

// This code doesn t work at all
byte[] artwork = values.get(position).getArtwork();
Bitmap bMap = BitmapFactory.decodeByteArray(artwork, 0, artwork.length);
imageView.setImageBitmap(bMap);

问题在于我失踪了什么? 艺术品变数不是正确的,还是我的要求是错误的?

或者,是否采取了更好的办法来获取图书封面和音乐信息?

我找到了另一种方式来做到这一点。我将拯救每一首歌的每个编目,然后,我可以用以下代码打饰艺术:

          Uri sArtworkUri = Uri.parse("content://media/external/audio/albumart");
          Uri uri = ContentUris.withAppendedId(sArtworkUri, Integer.valueOf(albumId));
          ContentResolver res = context.getContentResolver();
          InputStream in;
          try {
              in = res.openInputStream(uri);
              artwork = BitmapFactory.decodeStream(in);
              } catch (FileNotFoundException e) {
                  e.printStackTrace();
              }
