PasswordEditText | Custom EditTextView to show/hide password with icon | Android library

So I am starting to build a chat app and now I am at the registration screen.

Every time I press the login button,the request is sent only 1 time,like it should do. The problem starts when I get in return the error message(e.g "Your password is incorrect"),after I get the error,I am pressing the login button again with the same wrong password,and I get Log error that I made but its showing 3 times, at the same time and firebase tells me that I have made too many attempts....

This is what I have done:

I have created a simple demo project to test the default back stack feature of the Android Jetpack Navigation component.
I'm having one main activity and two fragments. The home fragment is being displayed when the app runs. The home fragment has a button. On click on that navigates to the other fragment.
But whenever I'm pressing the system back button my complete application is finished rather than the usual back stack behavior where I should see the home fragment.
Any help is appreciated. Thanks in advance.
The code is as follows :

I want to implement Clean Architecture in my recent app. But I faced some trouble of error handling in useCase. I can't handle exception thrown from Usecase class although other library based exceptions were successfully handled. It means, when any exception is thrown by Firebase, it is successfully handled and show the exception text in Toast. But when I throw any exception from Usecase class like

Please fill both field

or

Please give email

or

Please give password

then app crashed. So how can I handled the exception of use case class and show the text in Toast?

Here is code I tried.

I used material design 'com.google.android.material:material:1.3.0' in my Android app ( just to add password toggle for password field). I don't want other material features being included to my EditText.As you can see on the screenshot, blue line appears and also hint text goes up when PasswordEditText is touched. How can i get them rid of and leave only password toggle among material design features?

I am using material design 'com.google.android.material:material:1.3.0' in my Android app ( just to add password toggle for password field). I don't want other material features being included to my EditText.As you can see on the screenshot, green line appears when PasswordEditText is touched. How can i get it rid of and leave only password toggle among material design features? I tried to use app:boxBackgroundMode="none" app:boxStrokeWidth="0dp" app:boxStrokeWidthFocused="0dp" app:boxStrokeColor="@android:color/transparent" to remove the line but it didn't help.

Requirement: In Android app code, in MainActivity, I want to call a REST POST API through Volley and then pass the JSON response as it is in next Activity. But the response which gets passed is blank. The code is:

As mentioned in the title, my setError icon and endIconMode are fused in one
