Summary:
Not sure if I made this clearer or even more confusing,
but it's a try.

### Duplicate class `com.facebook.jni.*`
This can occur when mixing different versions of [FBJNI](https://github.com/facebookincubator/fbjni),
a library we use to interact with native C++ code.
Speficially, this can happen when the versions `0.0.x` and `0.1.x` are mixed. Version `0.1.0` of FBJNI
switched to using [Google Prefab](https://google.github.io/prefab/) for distributing native artifacts,
which made the split into combined, "java-only" and "header" packages redundant and only requires
a single dependency in your projects.
When including both "fbjni-java-only:0.0.1" and "fbjni:0.1.0" in one project, you will now
duplicate class errors during the build process. You must ensure that only one of the two
versions is used in your entire dependency tree. Start by looking at `./gradlew :myapp:dependencies`
to see where the different version requirements come from. Then exclude the FBJNI dependency from
one of them, e.g.
```groovy
implementation("com.facebook.react:react-native:+") {
exclude group:'com.facebook.fbjni'
}
```
