Is there any harm in just adding namespace no matter if we're on RN 0.70 or RN 0.73? Why do we need to check that?

Nope, that should do the trick @mrousavy . In fact, even Nicola suggested this as a viable approach. See: react-native-community/discussions-and-proposals#671 (comment)

Great - @MasonLe2497 can you update your PR to revert all changes in build.gradle and just have the updated AndroidManifest here? Thanks!
