系统重新启动我的进程后，AppWidget单击丢失。

public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
    for (int wid : appWidgetIds) {
        Log.i(TAG, \"onUpdate widget #\" + wid);

        Intent intent = new Intent(context, MyClass.class);
        intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, wid);

        PendingIntent clickIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

        RemoteViews widget = new RemoteViews(context.getPackageName(), R.layout.widget);
        widget.setOnClickPendingIntent(R.id.widget_layout, clickIntent);

        appWidgetManager.updateAppWidget(wid, widget);
    }

    super.onUpdate(context, appWidgetManager, appWidgetIds);
}
