Extend to Dialogflow v2 StreamingDetectIntent gRPC #2

Hi @MattLaurie Building gRPC stubs from existing googleapis is not well documented. So I was thinking if you could give some insight into how you generated the stubs for a particular folder from googleapis. I tried it out, but the protobuf build system for java / android always throws up dependency errors when i build an individual .proto file form the official googleapis repository. Same for folders. I could help in writing the client side logic and wiring it up as a library, but I am stuck at importing the proto files for a particular method.

To get this working for Cloud Speech required just going through the .proto files from googleapis [0] and copying across the dependencies manually - nothing more mysterious than that.

Note that this approach to building a gRPC client was only necessary because at the time there was no official Google SDK for the Cloud Speech v1p1beta1 APi. I would much rather have used an official library to avoid having to deal with protobuf directly.

In your case, you could also check android-docs-samples Dialogflow [1] example which looks to be using java-dialogflow [2] to make the gRPC calls. If nothing else it may help you track down where the dependencies are coming from.

Hope that helps.

Thanks. I actually ended up using the official library that you share the link for and it saved me a tonne of time. It still needed some integration since the samples were just for a stored audio file, I managed to wire it up with the Android AudioRecord and it works like a charm. The speech gets recognised in near real-time. I'll be open sourcing the whole solution soon.

Great, glad it worked out for you.

I spent a lot of time making a solid solution for realtime voice transcription on Android (and other platforms) so when you open source your code I'd be happy to take a look at it if that'd be helpful.
