Android studio git using private key

Ok, finally got it working!

What I did - switched to .ssh folder, then replaced contents of id_rsa key (as I understand, this is default ssh key of Android Studio) with contents of my ssh key.

Still don't know the way, how can I point Android Studio to my ssh key, but in such way it works.

As @CodeWizard mentioned, Android Studio was getting the key from the OS so using ssh-add to add the keys to the ssh-agent worked for me.

ssh-add ~/.ssh/id_rsa
