Unless you are using a library that includes native binaries (such as SQLCipher) then you don't need to do anything special to support 64 bit devices. If you are using such library then it should include 64 bit binary and it will then work. The latest version of SQLCipher includes 64 bit binary.
B4A Sdk Manager does support creating 64 bit emulators with x86_64 images.

Thank you
If I am using native binaries, I wanted to test if the execution is correct.
When I put an x86_64 image I imagine that by default it will execute in 64, but I have not known how to make sure or force it.
