待定意图未启动

Question

我有一个创建通知的活动。当我使用和 AVD 模拟器（针对 Android 2.1 更新 1）时，通知将很好地启动 PendingIntent，但在实际设备（运行 Android 2.2.1）上根本不会启动。有什么我缺少的基本内容吗？

您尚未发布任何代码。所以我分享了对我有用的代码：

public static void notifyIcon(Context context){

NotificationManager notifier = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.your_app_notification, "", System.currentTimeMillis());

/**
*Setting these flags will stop clearing your icon
*from the status bar if the user does clear all 
*notifications.
*/
    notification.flags |= Notification.FLAG_NO_CLEAR | Notification.FLAG_ONGOING_EVENT;
    RemoteViews contentView = new RemoteViews(context.getPackageName(), R.layout.custom_notification_layout);
    notification.contentView = contentView;

//If you want to open any activity on the click of the icon.

    Intent notificationIntent = new Intent(context, YourActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
    notification.contentIntent = contentIntent;

    notification.setLatestEventInfo(context, "title", null, contentIntent);
    notifier.notify(1, notification);

//To cancel the icon ...
    notifier.cancel(1);

}

这里是 custom_notification_layout.xml

<?xml version = "1.0" encoding = "utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="3dp" >

</LinearLayout>

注意：如果您设置了上述标志，请不要忘记在适当的时候清除您的应用图标。
