Question

我正在使用WSO2 EMM version 1.1.0

我正在关注enable GCM指南，但在配置完所有内容后，我在服务器端收到空引用异常

拉每X seconds consumes lots of battery，所以GCM是必须的。这会被修复还是有任何解决方法？

谢谢！

以下是我在设置为GCM时尝试连接服务器时的日志：

您是否在GCM API key配置文件中添加了WSO2 EMM server和发件人ID，您可以在EMM_HOME/repository/deployment/server/jaggeryapps/emm/config/config.json.?找到配置文件。配置如下：

"ANDROID": {
            "NOTIFIER_INTERVAL" : "30000",
            "NOTIFIER" : "GCM",
            "APIKEY" : "YOUR-KEY",
            "SENDERID" : "YOUR-SENDER-ID"
        },

WSO2 EMM GCM无法正常工作
