Android:来自BroadcastReceiver的通知

Question

我有一个启动广播接收器的报警管理器.这是我的广播接收器:

public class AlarmBrodcastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent arg1) {
        showNotification(context);
    }

    private void showNotification(Context context) {
        PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
                new Intent(context, MyActivity.class), 0);

        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(context)
                .setSmallIcon(0)
                .setContentTitle("My notification")
                .setContentText("Hello World!");
        mBuilder.setContentIntent(contentIntent);
        mBuilder.setDefaults(Notification.DEFAULT_SOUND);
        mBuilder.setAutoCancel(true);
        NotificationManager mNotificationManager =
            (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        mNotificationManager.notify(1, mBuilder.build());

    }  
}

广播开始及时,但没有通知,只有声音.文字在哪里？怎么了？是因为我使用API​​ 10和支持库吗？

哦,我发现了问题.问题是在.setSmallIcon(0)...当我设置一些真实资源时,它的确定,通知出现...
