When I try to load the app, instead of the login page, I see just a blank page with nothing. Can anyone help me why its happening? I don't see any error, logs or anything that can help me dig deep. Code is compiling fine but its just not showing me the page.
Here is all the code for your reference -

I explained in the problem that the page is not loading and there is no error or logs that I could see.
You have not added this in OnCreate method:
setContentView(R.layout.activity_login)
this might be the problem
