当设备关闭时，Android 设备中不会收到在 Worklight 中实现的推送通知

Question

Android 设备在关机时不会收到在 Worklight 中实现的推送通知。当我打开设备时，通知栏中永远不会收到设备关闭时发送的推送通知。

CASE OF FAILURE TEST STEPS（设备关机时发送推送通知）：

1. 关闭设备

2. 在设备关闭时向设备发送推送通知

3. 打开设备电源

4. 此 LogCat 显示，因此推送通知似乎正在到达设备。但是推送通知永远不会显示在通知栏中，也不会显示在应用程序中

LogCat：

05-14 14:39:12.250: V/GCMBaseIntentService(4829): Releasing wakelock

5. 在服务器端（websphere），日志每两分钟显示一次此消息：

    [5/14/15 8:36:26:581 EDT] 000002de BinaryDownloa E   FWLSE3002E: The resource is not found.
    com.ibm.worklight.admin.common.util.exceptions.NotFoundException: FWLSE3034E: The application "ParkUP" was not found in project "ParkingApp".
   

设备似乎正在接收来自服务器的推送通知，但通知未显示在通知栏上。

CASE OF SUCCESS CASE（设备开机且应用处于后台时发送推送通知）：

1. 将应用设置为后台

2. 向设备发送推送通知

3. 推送通知完美显示在通知栏上。此 logCat 显示。

LogCat：

05-14 15:05:54.620: W/ResourceType(1157): CREATING STRING CACHE OF 44 bytes

在这种情况下，除了调用 GCMIntentService.onUnhandled 之外，LogCat 与失败情况完全相同。

另外我想补充一点，如果我在设备无法访问互联网时测试发送推送通知，然后我让设备访问互联网，它也可以正常工作。

我已经测试了 worklight 教程中提供的示例，并且发生了同样的问题，但是在这种情况下，我没有使用 websphere 服务器进行测试，我正在使用本地 worklight 服务器进行测试，所以我没有请参阅服务器日志不适用于这种情况。

有没有人遇到过这个问题并找到了解决方案？

提前非常感谢您。

将其写为答案，因为评论有字符限制...这不是您所遇到问题的完整答案

• 当应用程序在前台时，通知栏不会显示消息，因为它会被应用程序使用。否则消息会转到通知栏。

• 当设备断电或不在网络中时，在设备连接网络时发送消息。如果应用程序不在前台，它会传递到通知栏。

据我了解，“应用程序已关闭”一词是指应用程序已关闭或即使在后台也没有运行……对吗？

从我对示例所做的测试中，我看到通知确实被传递到通知栏。此外，我没有在推送通知示例中看到“FWLSE3002E：找不到资源”。为了能够更好地帮助您，您能否描述一下您使用推送通知示例解决此问题所遵循的步骤。
