【问题描述】：
我想将 Google Cloud Messaging 后端添加到我的 android 应用程序（只是可用示例之一）。为此，我关注了官方documentation。我正在我的手机上部署（Android 5.0.2 的三星 A5）
在我添加后端之前，应用可以正常部署了。
添加后端后，后端可以正常部署在谷歌AppEngine开发服务器上，在浏览器中可以看到。
但是，当我尝试在我的设备上部署应用程序时，我最终得到了错误。
这和我的 Java 版本 (1.8) 有关吗？
我注意到堆栈跟踪中提到了 dex，所以它可能与 method number limit 有关？我没想到，因为它是一个非常小的示例应用程序，我认为我可能没有超过 64K 方法。
最后，我找到了一个类似的question，但没有帮助。
