How to add library versions for different architectures?

I have 4 versions of the library:

1. lib_arm7.aar
2. lib_arm8.jar
3. lib_x86.aar
4. lib_x86_64.aar

How can I add them correctly?

I added these files to the libs folder and added the following line to build.gradle:

implementation fileTree(include: ['*.jar','*.aar'], dir: 'libs')

But I have the following error:

Error: Program type already present:
