What I have tried:

Whenever I am trying to make a login page for my application, its showing login failed and its not passing intent as well as unable to pass the data on 2nd page of my application. I am helpless and not getting any idea to resolve this issue. I request you to kindly check my above coding and let me know if I have done anything wrong.

Have you stepped through the code using the debugger? Is an exception being thrown? What is being returned from loginResponse.getUsername()?

Sir, I am new into it and currently I am running the app on emulator, whenevr I am running the app, the login page is opening after that I am filling my credentials (email and password) and clicking on login button and the apps gets shut down automatically.

I am new to it and it is my first project. Can you please help me in this sir?
