Picasso出现“无法绘制回收位图”异常

我有一个音乐播放器应用程序，它与RemoteControlClient交互。我需要加载专辑封面图像以在锁定屏幕小部件中显示。我尝试使用Piccasso来实现这一点。我编写了以下代码：

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();

   ...
   }

但有时我会遇到异常：

我曾经尝试将加载的位图引用保存在我的服务中，但这并没有帮助。
有人知道我的代码有什么问题吗？
提前致谢。

我遇到了完全相同的问题。但是我不明白你所说的复制是什么意思。我有一个使用Picasso加载的图像列表视图，当我转到新活动并按返回键时，我的应用程序会崩溃并显示上述错误。 - Sriram
通过复制，我指的是Bitmap destBitmap = srcBitmap.copy(srcBitmap.config, false);并将destBitmap用作RemoteControlClient的参数。 - David Burström

我认为在这种情况下相关的部分是使用一个硬引用指向目标，而不是匿名实例。他正在使用一个硬引用，所以也许像你说的那样，他只需要取消请求来防止GC。不确定。 - Martin Marconcini

对我来说，解决方案是为现有的RemoteControlClient调用unregisterRemoteControlClient，并在每次播放新歌曲时创建一个新的RemoteControlClient。问题是当用户尝试播放两次相同的歌曲时产生的，当然使用相同的封面图片。
解决问题的代码片段如下：
if(mRemoteControlClientCompat!=null){
    RemoteControlHelper.unregisterRemoteControlClient(mAudioManager, mRemoteControlClientCompat);
}

Intent intent = new Intent(Intent.ACTION_MEDIA_BUTTON);
intent.setComponent(mMediaButtonReceiverComponent);
mRemoteControlClientCompat = new RemoteControlClientCompat(PendingIntent.getBroadcast(PlayerService.this, 0, intent, 0));
RemoteControlHelper.registerRemoteControlClient(mAudioManager, mRemoteControlClientCompat);

尝试在单独的线程中运行您的代码，它就可以工作了。

 new Handler().post(new Runnable() {
                          @Override
                          public void run() {
                             /// here is your code
                              bitmap_user=transform(bitmap);
                              imageButton.setImageBitmap(bitmap_user);

                          }
                      });
