Investigate android support #234
Description
We may need to change the low-level grpc dependencies to support android:
implementation 'io.grpc:grpc-okhttp:1.54.0'
implementation 'io.grpc:grpc-protobuf-lite:1.54.0'
implementation 'io.grpc:grpc-stub:1.54.0'
compileOnly 'org.apache.tomcat:annotations-api:6.0.53' // necessary for Java 9+
Investigate the scope of this change.
