Decompile apk and add new architecture support?

Question

Java

Is it possible to decompile apk to add support for a new architecture for the processor, and recompile?

Answer 1

If the APK is not cross-platform, then it has static libraries for a specific architecture. And they just can't be decompiled. Only reverse engineering, months of work, sometimes it's easier to do it again.
Or do you mean something else
