Yes, the example project builds perfectly. But as soon as I copy settings over to my projects, things start to break.
I'm new to Android, Gradle, and gRPC, so it's too easy for me to miss anything.. Sorry to borther. >From a beginner's point of view, the example project is too complicated and is not only "hello world". It's like a sub project in gRPC project and contains advanced examples, so I'm not sure which settings/codes are essential to the simplest helloworld demo, and it isn't organized in Android Studio‘s way.. It's just my two cents. I use Android Studio and my project structure is this, I have an Android module named as Client, and a Java module named as Protocol. Protocol module contains proto files and generates necessary gRPC classes. Client module references Protocol, and in the future when I create a Server module, it could also reference Protocol module.. I committed the project to GitHub. I would so appreciate if you could clone my *debug *branch and take a look. git clone -b debug https://github.com/gqqnbig/SimpleChat2017 在 2017年7月18日星期二 UTC-7下午1:48:09，Eric Gribkoff写道： > > You still need the javalite {} block in both protobuf.plugins and > protobuf.generateProtoTasks.
