我通过AppWidgetManager.updateAppWidget手动更新我的小部件时遇到了问题.平台是Android 2.2.

这是代码:
我在Manifest中另外声明了一个现有的Activity:

<receiver android:name=".Widget" android:label="@string/app_name">
        <intent-filter>

public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
    int use_static_ip;
    RemoteViews remoteViews;

    try {
        use_static_ip = Settings.System.getInt(context.getContentResolver(), Settings.System.WIFI_USE_STATIC_IP);
        if (use_static_ip == 0) { //DHCP
            remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_dhcp);
        } else { //static IP
            remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_static);
        }
        Intent call_activity = new Intent(context, StaticIPToggle.class);
        PendingIntent pending_call_activity = PendingIntent.getActivity(context, 0, call_activity, 0);
        remoteViews.setOnClickPendingIntent(R.id.widget_icon, …
