RemoteControlClient とやり取りする音楽プレーヤー アプリがあります。ロック画面のウィジェットに表示するには、アルバム カバーの画像を読み込む必要があります。これを実現するためにピカソを使用しようとしています。私は次のコードを書きました：
private final Target artworkTarget = new Target() {
@Override
public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom loadedFrom) {
remoteControlClient.editMetadata(false).putBitmap(RemoteControlClientCompat.MetadataEditorCompat.METADATA_KEY_ARTWORK,
bitmap).apply();
}
@Override
public void onBitmapFailed(Drawable drawable) {
Log.e(Constants.LOG_TAG, "Artwork loading failed");
}
@Override
public void onPrepareLoad(Drawable drawable) {
}
};
...
private void playNextSong(int songPosition) {
...
String artworkUrl = Constants.Urls.BASE_ARTWORK_URL + currentSong.getArtworkId();
Picasso.with(this).load(artworkUrl).skipMemoryCache().into(artworkTarget);
// Update the remote controls
remoteControlClient.editMetadata(true)
.putString(MediaMetadataRetriever.METADATA_KEY_ARTIST, currentSong.getArtist().getName())
.putString(MediaMetadataRetriever.METADATA_KEY_ALBUM, currentSong.getAlbum().getName())
.putString(MediaMetadataRetriever.METADATA_KEY_TITLE, currentSong.getName())
.apply();
...
}
しかし、時々例外が発生します:

私のコードの何が問題なのか誰にもわかりませんか?
前もって感謝します。
