React native link creates duplicate entries

Question

I don’t know why it react-native linkcreates duplicate records in MainApplication.java(during import and in the getPackages function), but it app\build.gradle’s compile projectnot added to the record , but if I run the command again, I get the same message instead of the module already connected.

When I start react-native link, I get messages that the module was successfully connected on Android (duplicated), and on iOS it was already connected.

Many users are faced with a problem on Android (including me). This is due to the difference between iOS and Android code.

In my case, this was due to the RN version and local libraries.

I solved this by removing duplicate libraries on Xcode.
