Android Question Conflict in merge for keyvaluestore and sqlcipherb4a when R8optimize is true

[mcqueccu]

Sqlcipherb4a depends on sqlite-2.4.0.aar and when I add keyvaluestore, it seems to be pulling some AndroidX SQLite 2.5.2, hence creating a merge conflict when compiling with R8 optimization = true

This issue will only happen in debug mode. You can workaround it by adding a few proguard rules, however it is better to test R8 in release mode. I will update the tutorial.

 

[mcqueccu]

You are right. It works in Release Mode with no errors (with just the two libraries: SQLCipherB4A and Keyvaluestore Libraries)


But, when I run the main project code, which has lots of libraries, I get a compilation error even in release mode. I think there is another library which is conflicting.

These are my libraries

 

[Erel]

This is a real conflict. Try to remove <dependsOn>sqlite-2.4.0.aar</dependsOn> from the end of SQLCipherB4A.xml. Refresh the libraries.

 

[mcqueccu]

Ok. I have narrowed it down to FIREBASEADMOB2 by removing the libraries one after the other and compiling.

Removing both these lines SOLVED it. Removing only the dependon line did not solve it

1. <dependsOn>sqlite-2.4.0.aar</dependsOn> from the end of SQLCipherB4A.xml.
2. #AdditionalJar: sqlite-2.4.0.aar

Now: All libraries are working together
Keyvaluestore, SQLCipherB4A, and FirebaseAdmob2

Thank you community
