重新启动后，按钮单击时，小组件onUpdate未设置pendingIntent

Question

我正在创建一个测试小部件，通过单击其按钮显示随机数。一切都在我的onUpdate独立的Provider内，包括pendingIntent。它工作正常，但重新启动后手机views.setOnClickPendingIntent不工作虽然RemoteViews重新创建没有问题，但按钮变得反应迟钝。

public class TestWidget extends AppWidgetProvider {
    static HashMap<Integer, BroadcastReceiver> br = new HashMap<>();

    static void updateAppWidget(Context context, final AppWidgetManager appWidgetManager,
                                final int appWidgetId) {
        context = context.getApplicationContext();
        final RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.test_widget);

        BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                views.setTextViewText(R.id.appwidget_text, Math.random() + "");
                appWidgetManager.updateAppWidget(appWidgetId, views);
            }
        };
        br.put(appWidgetId, broadcastReceiver);//to unregister later

        Intent intent = new Intent("action");
        IntentFilter intentFilter = new IntentFilter("action");

        context.registerReceiver(broadcastReceiver, intentFilter);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 123, intent, PendingIntent.FLAG_UPDATE_CURRENT);
        views.setOnClickPendingIntent(R.id.appwidget_button, pendingIntent);

        appWidgetManager.updateAppWidget(appWidgetId, views);
    }

    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        for (int appWidgetId : appWidgetIds) {
            updateAppWidget(context, appWidgetManager, appWidgetId);
        }
    }

    @Override
    public void onDeleted(Context context, int[] appWidgetIds) {
        for (int appWidgetId : appWidgetIds) {
            context.unregisterReceiver(br.get(appWidgetId));
        }
    }
}
