This should fix build for Android because jcenter was shutdown.

fixes #1039

I replaced whole repositories section with same that default RN template use.

Thks for doing this! Just out of curiosity, any reason why I am not experiencing a build failure due to jcenter being offline. Is it offline?

[Nodonisko]

Honestly I am not sure. I have problems to find exact information when jcenter exactly will be offline completely. I guess it could be some kind of cache of maybe servers for your location still works...

For us build started to fail everywhere. Did you tried to build lib itself or app that is using library?

We had the same problems, on multiple apps, but only when building in "release" mode. Building locally in android studio would work, but taking a long time. I don't have any clear information neither, but I too suspect some local cache or fallback

Hi, this looks good to me, I've gone through and compared to the current RN files as well and it makes sense.
