应用程序引擎（蚀）：无法从Android模拟器注册设备端点 [英] app engine(eclipse): can't register device from android emulator to endpoint
问题描述
我刚开始探索与Android App Engine和我跟着一个链接，教我如何建立AAPP引擎连接的Android项目。
https://developers.google.com/eclipse/docs/endpoints-androidconnected-gae
I am just started exploring app engine with android and I followed a link to teach me how to create aApp Engine Connected Android Project. https://developers.google.com/eclipse/docs/endpoints-androidconnected-gae
我跟着正是写于链接，
1）连接创建一个新的应用程序引擎的Android项目
1) Created a new app engine connected android project
2）获取从 HTTPS的项目数量和API密钥：// code.google.com /的API /控制台/＃项目
3）在谷歌API的控制台使谷歌云通讯
3) enable Google Cloud Messaging in the Google APIs Console
4）LOCAL_ANDROID_RUN设置为true CloudEndpoints类
4) set the LOCAL_ANDROID_RUN to true in CloudEndpoints class
5）使用仿真器与谷歌API（V17）
5) used a emulator with google api(v17)
6）安装了Android SDK中经理的android云消息库
6) installed the android cloud messaging library from android sdk manager
7）我使用的Eclipse靛蓝
7) I am using eclipse indigo
我开始本地主机：8888和它的作品在网络上完全正常
但是当我运行模拟器和我pssed注册按钮$ P $，它会立即停下来，检查我的logcat，它显示这个错误，我不就是我应该做的。
I started the localhost:8888 and it's work perfectly fine on the web but when I run the emulator and I pressed on the register button , it stopped immediately and I check my logcat, It display this error which I don't what I should do about it

AP preciate如果有人能帮助我解决，我有我的问题。谢谢
appreciate if anyone can help me solve my issue that I am having. Thanks
推荐答案
看着这个狭义的，它很可能是existingInfo为null。
Looking at this narrowly, it is likely that existingInfo is null.
更广泛地说，它出现在你onRegistered功能执行的端点。对于初学者来说，调用一个端点是同步操作，因此不应该在onRegistered完成。
More broadly, it appears that in your onRegistered function you execute an endpoint. For starters, invoking an endpoint is a synchronous operation so it shouldn't be done in onRegistered.
如果我理解你的code正确，你应该改变这种状况。我建议你应该脱钩从终端code您的GCM code。
If I am understanding your code correctly, you should change that. I would suggest you should 'de-couple' your GCM code from your endpoints code.
另外，我建议你检讨实施GCM的说明：结果

Also, I suggest you review the instructions for implementing GCM:
