将Parcelable数组从AppWidgetProvider传递到RemoteViewsService

Question

我正在尝试将一些可分隔的数组传递给RemoteViewsFactory到RemoteViewsService。在我的自定义AppWidgetProvider内，我有如下情况：

Intent appWidgetIntent = new Intent(context, ReportRemoteViewsService.class);
appWidgetIntent.putParcelableArrayListExtra("list", list);
appWidgetIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetIds[i]);

RemoteViews rv = new RemoteViews(context.getPackageName(), R.layout.appwidget_report_layout);
rv.setRemoteAdapter(R.id.appwidget_report_listview, appWidgetIntent);
//dumpIntent(appWidgetIntent);
appWidgetManager.updateAppWidget(appWidgetIds[i], rv);

list是ArrayList<CustomObject>其中CustomObject implements Parcelable（writeToParcel和静态CREATOR）。我正在打印额外内容，并且列表和ID都有，但是当我在Intent内打印RemoteViewsFactory时，只有appWidgetId ...

public class ReportRemoteViewsService extends RemoteViewsService {

    @Override
    public RemoteViewsFactory onGetViewFactory(Intent intent{
        //dumpIntent(intent);
        return new ReportRemoteViewsFactory(this.getApplicationContext(), intent);
    }
}

当我尝试传递单个parcelable（不是数组）时的情况相同。为什么？！
