Android-nRF-Mesh compilation error after downloading Android source code

[zero]

Based on Android studio 3.0, gradle-4.10.1 compile the project downloaded from github.com/.../android-nrf-mesh-library. I get the following error:

The module 'app' is an Android project without build variants ,and cannot be built.
Please fix the module's configuration in the build.gradle file and sync the project again.

The module 'meshprovisioner' is an project without build variants ,and cannot be built.
Please fix the module's configuration in the build.gradle file and syne the project again.

What can I do to ensure that I can compile and pass？

@zero have you tried upgrading your android studio version to see if it helps?

HI 

The highest version is Android studio 3.5. It should not be much different from Android studio 3.0, but I will still try it. What is your Android studio version?

I'm using the latest 3.5

Is there any other reason than the version?

Are you sure you have cloned the full project repository correctly? I also suggest open android studio import project and open nrf-mesh which is inside the Example folder in the repository.
