Question

我正在尝试Android手机和平板电脑的推送通知，我们正在使用IBM Worklight（see blog post）提供的示例代码。

我们已在Google GCM注册并获得了项目ID和API密钥;这些代码适用于平板电脑，但是当我用手机运行同样的时候，订阅会返回false，任何人都可以请测试这里给出的代码，让我们知道我们做错了什么是因为它无法在多个设备上运行。

我们已从示例代码中删除了禁用，这样我们就可以检查平板电脑2是否已订阅，以下日志清楚地显示设备未订阅。

Answer 1

请检查您的互联网连接，因为您在第二台设备的日志中看到的错误是：

01-01 10:27:23.340: V/GCMBaseIntentService(9400): Intent service name: GCMIntentService-804999789155-7
01-01 10:27:23.340: D/GCMBaseIntentService(9400): handleRegistration: registrationId = null, error = SERVICE_NOT_AVAILABLE, unregistered = null
01-01 10:27:23.340: D/GCMBaseIntentService(9400): Registration error: SERVICE_NOT_AVAILABLE

这意味着您的应用无法注册GCM服务以获取令牌，因为GCM服务似乎不可用，因此错误SERVICE_NOT_AVAILABLE可能是因为您的互联网连接问题或GCM可能在您尝试时无法使用这个。所以再试几次。

另请注意，现在您正在另一台设备上运行您的应用程序，这意味着您需要再次进行订阅，即使您以同一用户身份登录（如在第一台设备上）。所以isSubscribed（）正确返回false 。

订阅呼叫本质上意味着将此特定设备上的登录用户订阅到给定的事件源。由于您尚未订阅此第二个设备（即使在第一个设备上订阅了相同的用户），isSubscribed（）返回false。
