Whitelabel guide

Hi
Im trying to follow the whitelabel guide for android. I manage to get the std master branch running as an app within android studio and can use in an emulator. Once i start making changes as per guide the app will be not run i get various errors. Is there a more detailed guide?

One of the steps says to edit package names in various .java files that dont seem to exist in the single server branch or the master branch!?
Thanks

We’re going to update the docs to match 4.12 release next week, but you should be able to do it anyway.
We’ve separated the app in two build flavours, but you can find the .java on the main folder. https://github.com/RocketChat/Rocket.Chat.ReactNative/tree/develop/android/app/src/main/java/chat/rocket/reactnative

Hi
I did manage to cobble something together but t it was very long winded and not like the guide!
Will wait for the new guide
Thanks
