Question

您好我已经创建了一个Android应用程序，我想要GCM注册ID。

但是我在获取GCM的注册ID时遇到错误。

我得到的错误就像 -

resetting backoff for idev.android.rchat

我已将以下代码添加到我的主要活动的onCreate中：

    GCMRegistrar.checkDevice(this);
    GCMRegistrar.checkManifest(this);
    final String regId = GCMRegistrar.getRegistrationId(this);
    if (regId.equals("")) 
    {          
        GCMRegistrar.register(this, SENDER_ID);
    }

    Log.v("REG ID:",""+regId);

清单文件是 -

Answer 1

我认为您将获得注册ID为null。我遇到同样的问题我通过以下本教程程序解决了这个问题，它将被解决。

并再记下一点 .GcmIntentservices 必须在应用程序的根软件包中，您必须将其放在idev.android.rchat上，然后才能正常工作。

Android GCM不起作用
