我正在进行小部件点击。 它的工作在背景中应用完美。 关闭应用程序后，它返回ERROR。 如果有任何解决方案，请告诉我。

现在我已将我的代码附加到widgetprovider类
中private RemoteViews updateWidgetListView(Context context, int appWidgetId) {
// which layout to show on widget
RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
R.layout.task_list_widget);
// RemoteViews Service needed to provide adapter for ListView
Intent svcIntent = new Intent(context, WidgetService.class);
// passing app widget id to that RemoteViews Service
svcIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
// setting a unique Uri to the intent
// don't know its purpose to me right now
svcIntent.setData(Uri.parse(svcIntent.toUri(Intent.URI_INTENT_SCHEME)));
// setting adapter to listview of the widget
remoteViews.setRemoteAdapter(appWidgetId, R.id.widget_list, svcIntent);
// setting an empty view in case of no data
remoteViews.setEmptyView(R.id.widget_list, R.id.txt_no_data);
Intent startActivityIntent = new Intent(context, getClass());
// startActivityIntent.putExtra("from", "widget");
startActivityIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivityIntent.setAction("list");
PendingIntent startActivityPendingIntent = PendingIntent.getActivity(context, 0, startActivityIntent, PendingIntent.FLAG_UPDATE_CURRENT);
remoteViews.setPendingIntentTemplate(R.id.widget_list, startActivityPendingIntent);
// remoteViews.setOnClickPendingIntent(R.id.btn_widget_sos, startActivityPendingIntent);
// Intent intent = new Intent(context, Home.class);
// PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
// // Get the layout for the App Widget and attach an on-click listener to the button
// remoteViews.setOnClickPendingIntent(R.id.widget_list, pendingIntent);
return remoteViews;
