我正在构建一个消息传递应用程序，并使用sinch和解析消息传递客户端。我们按照https://www.sinch.com/tutorials/android-messaging-tutorial-using-sinch-and-parse/中的sinch教程构建了一个简单的信使。
完成此操作后，我按照以下步骤添加了后端：https://cloud.google.com/mobile/app_engine/add_module
首先，gradle不会构建，直到我将multiDexEnabled = true添加到build.gradle（一个我似乎找不到的SO帖子提供修复。）
现在gradle构建，后端在localhost:8080.
但现在当我运行信使应用程序时，我得到了
此行的java.lang.NoClassDefFoundError usersListView.setOnItemClickListener（新 ListUsersActivity中的AdapterView.OnItemClickListener（）。
同样，我收到了LoginActivity的错误：
停止未恢复的活动： {com.myapp / myapp.LoginActivity} java.lang.RuntimeException：执行停止未恢复的活动
我非常困惑，因为应用程序在添加简单的后端之前运行正常，后端似乎正在运行。如果还有其他我可以提供的帮助来追踪这一点，请告诉我。我已经用谷歌搜索了我的屁股并且什么都没有。

编辑2： 看到一篇SO帖子，表明构建顺序可能不稳定。因此，我删除了我的构建文件夹并进行了干净的构建。仍然有错误，但他们现在已经改变了：
