Updated reactive dependencies

[davrukin]

Updated reactive dependencies (RxJava 2 -> 3, RxAndroid 2 -> 3, RxBin…ding 1 -> 4) and removed RxJava2Interop

I have a project in which I’m upgrading all the above listed libraries, and it also uses rx-preferences, which doesn’t have these libraries updated.

Compiled and installed test app, and it works on my Pixel 4.

I’m not sure what you mean since there’s no pom.xml.

I’m also not sure why the Travis build is failing, since it’s working with no issues on my end.

The groupId is defined in the root gradle.properties. The package name of all types will need to switch to a "3".

Is there anything else that I may have missed?

It looks like we may need to update the CI config to accomodate this change:

I’m not sure what changes to make in the yml; are you able to?
