How to fix this bug? On IOS everything works, on Android it doesn't work.

Answer 1

Errors of this kind are quite common. Need more data, version of rn, babel and everything else.
First you need to check the entry point, judging by the error, it does not find android. Probably not called for it. AppRegistry.registerComponent
It is possible that the problem is with the network and cannot reach the dev server. As an option, if connected via adb reverse cable, use it.
