Android: combining the same library's different versions where one is old and one is migrated in a project

Question

For my image processing project on android, I need to use the two libraries:

1. android_face_detection

2. EPassportNFCReader

I want to combine these to libraries in a project to make a library and use them in my real project. There is an inconsistency in the dependencies. I've figured out that the following libraries don't work together since one of them is the migrated version of the other.

 com.google.firebase:firebase-ml-vision:24.1.0       //used by 1.
 com.google.android.gms:play-services-mlkit-text-recognition:16.1.2  //used by 2.

I've figured out that Google migrated the firebase-ml-vision to com.google.android.gms. I tried to migrate the first project but figured out that the migration is not easy for the first library.

Is there a way to use those together?

The duplicate errors I've got if I put the libraries together:

Answer 1

The suggestion would be NOT to mixed use of these two libraries, since the symbol duplication issues mentioned above.

We provided a migration doc here: https://developers.google.com/ml-kit/migration/android

We are happy to help if there is any migration issue in the process.
