Can not set android clang compilers for Qt Android on Ubuntu

[advm]

I installed Qt Android 5.15.2 on Ubuntu but there is problem with the compilers. This is what I have set:

And here is what QtCreator detects as compilers:

The first error is displayed here in the Qt version tab:

and also in the Kit tab I see this errors no matter which compilers I set from the available:

Why I got this errors? Can please someone that has android kit on Ubuntu already set, tell me which compilers is using and which paths are for the compilers?
I will add more information for the current compilers or kits if needed.

@advm from a quick look of the provided screenshot, I would say, QtCreator did not find any Android specific compilers, those are usually found inside the ndk tool chain folder.

for example for me it looks like this

did you install the compilers correctly? Do you find the compiler in the specified folders?

@J-Hilk thank you for answer. I have tried following the screenshot you posted but still got error.
Should I try with other NDK version or it doesn't matter?
Here are more images after latest changes:

Found the problem. It looks like the ndk that I have installed was missing some files. After downloading it again the compilers are auto-detected and everything works fine. Thanks @J-Hilk
