Android example compilation fails at app:generateDebugProto task

[vpejovic]

Describe the bug

Compiling the Flower Android example (available at https://github.com/adap/flower/tree/main/examples/android ) using Android Studio Bumble Bee on MacBook Pro M1 fails at ':app:generateDebugProto' task. In addition, the MainActivity includes FlowerServiceGrpc class, which is not available in the given repository.

Steps/Code to Reproduce

Pull https://github.com/adap/flower/tree/main/examples/android , import the client to Android Studio, and compile.

Expected Results

The app compiles without errors.

Actual Results

Execution failed for task ':app:generateDebugProto'.

Could not resolve all files for configuration ':app:protobufToolsLocator_protoc'.
Could not find protoc-3.11.0-osx-aarch_64.exe (com.google.protobuf:protoc:3.11.0).

[vpejovic]

Appears to be an issue with the protoc support on M1. os72/protoc-jar#93
Installing protoc locally via homebrew and instructing gradle to fetch it from the path (e.g. protoc { path = '/opt/homebrew/bin/protoc'}) solves the issue.
