can't start train on Android

[Devil-Ideal]

你好，我在学习你的GitHub项目End2end-Federated-Learning，在实践过程中遇到了一些问题，再将Android设备加入系统后，并没有开始训练，如果你有时间赐教，我将不胜感激。
I encountered some problems during my study of your GitHub project end2end federated learning. After I added the Android device to the system, it didn't start training. If you'd like to give me some advice, I would be more than grateful

After checking the code, I found that the compiler marked all c++ code red, but I didn't understand the reason for the error

details are below：

After updating the gradle, the above error is resolved, but the client cannot join the system and is waitin

很抱歉这么晚回复您
我想知道，客户端是在加入系统时卡住的吗？这个时候服务端界面又是什么状态，是否显示加入成功呢？

Sorry for answering you so late.
Please tell me, when was the client stunk? When it joined the system? At the same moment, what was the state of server?What did the interface of the server display?
