So I have updated this: implementation(project(':SA')) {transitive = true }

to implementation files('libs/SA.aar')

Now I am getting this error:

java.lang.RuntimeException: Duplicate class a.a.a found in modules classes.jar (SA.aar) and classes.jar (com.google.ar:core:1.12.0)
  Duplicate class a.a.b found in modules classes.jar (SA.aar) and classes.jar (com.google.ar:core:1.12.0)

  Duplicate class com.google.a.a.b found in modules classes.jar (SA.aar) and classes.jar (com.google.ar:core:1.12.0)

How should I resolve this?

So you have an obfuscated build here, try disabling this obfuscation first and see if the issue persists.

If it persists it is likely showing you the actual dangling class, which - most of the time - points you to one or more libraries that depend on a conflicting 3rd party dependency, in which case you'd simply exclude that dependency from being included transitively into your build.

If it does not persist in a non-obfuscated build, check your symbols file to get the name of the class / program type a.a.a was obfuscated to. This file usually resides somewhere underneath app/build/outputs/**/mapping.txt.

It might also totally be a temporary issue, in this case make a clean build and try again.

Seeing your build.gradle file it looks you have added legacy library and your SA module twice

implementation 'androidx.legacy:legacy-support-v4:1.0.0'
implementation(project(':SA')) {transitive = true}

The culprit is the second one.

Maybe that can be the your issue as the error says about duplicates.

Trying removing the same or maybe you dont need that legacy library itself I think.

Because sometimes it gets added in my build.gradle automatically and I have to remove that manually.
