Everything looks fine.but when i add packages.add(new ReactViroPackage(ReactViroPackage.ViroPlatform.valueOf("AR")));

into mainapplication.java file app crashed and when i remove it app running normaly but i got error message Ui manage not found. so what i have to do for solve this issue. Thank you

[bilewinters]

Hello! Have you tried building and running our starter-kit app?

https://github.com/ViroCommunity/starter-kit

It has all the config and MainApplication.Java changes already in it. If you can run that, then it will help us work out if there is a problem, or if you have missed a step somewhere.

We also recommend using the stater kit if you are starting a new AR project in any case!

Hi Thank you for reply. yes i tried but same error. :/

[bilewinters]

Hi @websasindu in that case I think there is something wrong with your setup, and issues isn't the place to resolve this - come and join our discord, there is a good community who help with these kinds of problems:
