Android AppWidget的按钮点击事件在家庭启动器强制停止后未收到

Question

我有一个应用程序小部件，点击事件可以在我的提供程序中以onUpdate()接收。
但是，当我尝试强制关闭主启动器时，单击事件丢失了。
我什至在所有onEnabled()中都放置了断点，onReceived()...等：连接似乎丢失了。

因此，如何"重新连接"按钮事件？

WidgetProvider 扩展AppWidgetProvider：

@Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        Log.d(TAG, "onUpdate()");
        Log.d(TAG, "isLoading: " + CONSTANT.isLoading);
        // update each of the widgets with the remote adapter from updateService
        // Get all ids
        ComponentName thisWidget = new ComponentName(context, ScoreWidgetProvider.class);
        int[] allWidgetIds = appWidgetManager.getAppWidgetIds(thisWidget);
        // Build the intent to call the service
        Intent intent = new Intent(context.getApplicationContext(), UpdateWidgetService.class);
        intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, allWidgetIds);
        // Update the widgets via the service
        context.startService(intent);
//      super.onUpdate(context, appWidgetManager, appWidgetIds);
    }  

UpdateWidgetService 扩展Service：

@Override
        public void onStart(Intent intent, int startId) {
            Log.i(TAG, "Called");
            AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(getApplicationContext());
            int[] appWidgetIds = intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS);
            for (int i = 0; i < appWidgetIds.length; ++i) {
                // Here we setup the intent which points to the StackViewService which will
                // provide the views for this collection.
                Intent remoteViewsIntent = new Intent(this.getApplicationContext(), ScoreWidgetRemoteViewsService.class);
                remoteViewsIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetIds[i]);
                // When intents are compared, the extras are ignored, so we need to embed the extras
                // into the data so that the extras will not be ignored.
                remoteViewsIntent.setData(Uri.parse(remoteViewsIntent.toUri(Intent.URI_INTENT_SCHEME)));
                RemoteViews rv = new RemoteViews(this.getApplicationContext().getPackageName(), R.layout.widget_layout);
                rv.setRemoteAdapter(appWidgetIds[i], R.id.score_list, remoteViewsIntent);
                // Set the empty view to be displayed if the collection is empty.  It must be a sibling
                // view of the collection view.
                rv.setEmptyView(R.id.score_list, R.id.empty_view);
                // Bind the click intent for the refresh button on the widget
                final Intent refreshIntent = new Intent(this.getApplicationContext(), ScoreWidgetProvider.class);
                refreshIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                refreshIntent.setAction(ScoreWidgetProvider.REFRESH_ACTION);
                final PendingIntent refreshPendingIntent = PendingIntent
                        .getBroadcast(this.getApplicationContext(), 0, refreshIntent, PendingIntent.FLAG_UPDATE_CURRENT);
                rv.setOnClickPendingIntent(R.id.btn_refresh, refreshPendingIntent);
                appWidgetManager.updateAppWidget(appWidgetIds[i], rv);
            }
    //        stopSelf();
            super.onStart(intent, startId);
        }

确保在onStart函数中使用正确的上下文。 签出 getApplicationContext 在代码的onStart部分中，传入错误类型的上下文可能会导致错误。以下是更多信息的链接：上下文。
