Hello,
I have gone through your requirements, You want to install android studio in your PC, change domain name in code & generate build after. So, Yes I can complete this task in within a hour.
I am very familiar with TeamViewer/anydesk so its easy for me to do this task.
I have now expertise in Android development so I will complete it within hour & can start work on it right now.
Let me know if you are interested, I am ready to work on it.
Thanks,
Hardip
