Error: more than one library with package name 'com.facebook.react'

I have a react native project that was auto-generated by https://getexponent.com/ when I detached the project. Now I'm getting these build errors after I added react-native-lock with react native link. It works fine as an iOS project with xcode, but android studio is giving me this error:
Error:Execution failed for task ':app:processDebugResources'.

try adding multiDexEnabled as true in your
buildType{ release{ multiDexEnabled true} }
hope it works for you..
