Albüm Adı İle Albüm Alınan Albüm Olun Android

Question

Albüm adı ile albüm resmini liste görünümünde görüntülemek istiyorum. Ama albüm sanatını görüntülemenin yolunu bulamıyorum. cover art on android'dan denedim.

İşte benim Kod geçerli:

Cursor cursor = managedQuery(MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI, null, null, null, null); 
      if (cursor == null) 
      { 
       //Query Failed , Handle error. 
      } 
      else if (!cursor.moveToFirst()) 
      { 
      //No media on the device. 
      } 
      else 
      { 
       int titleColumn = cursor.getColumnIndex(android.provider.MediaStore.Audio.Albums.ALBUM_ART); 
       int id = cursor.getColumnIndex(android.provider.MediaStore.Audio.Albums.ALBUM_ID); //here value i m getting -1 . 

       for(int i=0;i<cursor.getCount();i++) 
       { 
        if(id<0) 
        { 
         Long album =Long.parseLong(cursor.getString(id)); 
         String coverPath = cursor.getString(titleColumn); 

         Context context = null; 
         ContentResolver res = context.getContentResolver(); 
         Uri uri = ContentUris.withAppendedId(sArtworkUri, album); 
         if (uri != null) 
         { 
          InputStream in = null; 
          try 
          { 
           in = res.openInputStream(uri); 
           Bitmap b = BitmapFactory.decodeStream(in, null, sBitmapOptions); 
           ImageView coverAlbum=(ImageView)findViewById(R.id.thumbnail); 
           coverAlbum.setImageBitmap(b); 

          } catch (FileNotFoundException ex) 
          { 

          } 

         } 

        } 
         //code to insert in listview 
        cursor.moveToNext(); 
       } 
      } 
      cursor.close(); 
} 

Ama Album_ID alıyorum -1. Bu yüzden albüm için album_id alamıyorum ama sdcard'ımda albüm şarkısı yaşıyorum. Ve sdcard bazı dosyalar içeren albümleri gibi klasörlere sahip. Yani albüm adı ve sanat almak için bana bir çözüm verin. Önceden Thanx. Şarkı bilgilerle albüm kapağı almak için Code Below

Bu benim hata günlüğü olduğunu. şarkı listesi yerine sadece albüm adlarını görüntülemek için hafifçe değiştirebilirsiniz.
