Here is the versions I am using
The problem is the project I created using react-native init AddisMereja
is of size 20MB.
It does not have anything.
I believe you are talking about the size of the apk
file that is generated. If so you can try using app bundle and submit the app bundle to google play store which will handle it according to users device as the apk
that is generated by default contains apps for different architectures but you will end up using only one of them.
This blog post by Krzysztof Magiera explains the process better.
