android - Android主屏幕小部件：无法更改ImageButton图像资源

Question

我正在尝试通过广播消息从服务应用程序更改“AppWidgetProvider”的 ImageButton 图像源。从服务“updateAppWidget”方法被正确调用，但“R.id.widget_play_stop_btn”图像资源没有改变。

private static void updateAppWidget(Context context, AppWidgetManager appWidgetManager,
                                    int appWidgetId) {
    if (AppConstants.selectedAudioModel == null) {
        Log.e(TAG, "TODO");
        return;
    }
    RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.music_player_widget);
    remoteViews.setTextViewText(R.id.widget_audio_title, AppConstants.selectedAudioModel.getTitle());
    remoteViews.setTextViewText(R.id.widget_audio_artist, AppConstants.selectedAudioModel.getArtist());
    int playStopButtonDrawableId =  AppConstants.isPlayingMusic ? R.drawable.stop : R.drawable.play;

     Log.e(TAG, "updateAppWidget:"+playStopButtonDrawableId+" "+AppConstants.isPlayingMusic);

    remoteViews.setImageViewResource(R.id.widget_play_stop_btn, playStopButtonDrawableId);
    AppWidgetManager manager = AppWidgetManager.getInstance(context);
    manager.updateAppWidget(appWidgetId, remoteViews);
}

奇怪的信息：当我运行调试并逐行执行代码时，图像资源正确更改。我正在Android 10中进行测试。有人可以帮忙吗？

已编辑：这是调用更新小部件的方式。并且在调用updateMusicPlayerIWidget之前，AppConstants.isPlayingMusic被正确修改

 private void updateMusicPlayerWidget() {
        Intent intent = new Intent(getApplicationContext(), MusicPlayerWidget.class);
        intent.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
        int ids[] = AppWidgetManager.getInstance(getApplication()).
                getAppWidgetIds(new ComponentName(getApplication(), MusicPlayerWidget.class));
        intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS,ids);
        sendBroadcast(intent);
    }

这是 ImageButton 描述：

<ImageButton
        android:id="@+id/widget_play_stop_btn"
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:clickable="true"
        android:src="@drawable/play"
        android:adjustViewBounds="true"
        android:scaleType="fitCenter"/>

这是示例 Logcat：
