May I ask how to solve it

Hello

Current targets specified in https://github.com/joaovarelas/Obfuscator-LLVM-16.0/blob/main/Dockerfile#L102

are ["x86_64-unknown-linux-gnu", "x86_64-pc-windows-gnu"]

I don't know if it works for android. You can test and let me know

EDIT: look into https://obfuscator.re/omvll/
