我正在尝试用启动时钟应用程序制作一个小部件

为什么这段代码在真实设备上不起作用

我做错了什么

@Override
public void onReceive(Context context, Intent intent)
{
    String action = intent.getAction();
    PendingIntent pendingIntent;
    if (AppWidgetManager.ACTION_APPWIDGET_UPDATE.equals(action))

        RemoteViews views = new RemoteViews(context.getPackageName(),
                R.layout.clock_appwidget);

        pendingIntent = PendingIntent.getActivity(context, 0,getAlarmPackage(context), 0);
        views.setOnClickPendingIntent(R.id.imageView1, pendingIntent);

        AppWidgetManager.getInstance(context).updateAppWidget(
                        intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS),
                        views);
    }
}


public Intent getAlarmPackage(Context context)
{
    PackageManager packageManager = context.getPackageManager();
            Intent AlarmClockIntent = new Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_LAUNCHER);

    String clockImpls[][] = {

        try
        {
        ComponentName cn = new ComponentName(packageName, className);
        packageManager.getActivityInfo(cn,PackageManager.GET_META_DATA);
            AlarmClockIntent.setComponent(cn);

我在emulator上运行应用程序,然后单击小部件-这项工作。在安卓4.0.3、2.2上测试可能会发现,您的新设备具有新的时钟实现,但不在clockImpls列表中。例如,如果您有新的Xperia Z时钟,则可以将其添加到列表中:

{ "Sony Ericsson Xperia Z", "com.sonyericsson.organizer", "com.sonyericsson.organizer.Organizer_WorldClock" }   

在某处创建完整的列表是个好主意。

您必须放置更多日志语句,并检查它被阻止的位置。此接收器类别的目的过滤器是什么?或者它是AppWidgetProvider类?
