perfect tutorial, thank u so much.
1) Question !!
- why firebaseAuth.getCurrentUser() != null ?
- this will straight open up the profile activity whenever u click the app instead of login or registering your account
- i have removed it in order to log in my account first before getting into the app

Hello! Why do you put the finish() before the startActivity and not after it?

It freeze's on Please wait progress dialog for log in and does not go to profile activity however it works when I register a new user and it goes to profile activity. HELP!

[motorheadbanger]

Does firebase have sessions? So that way if the user is inactive in the app for x amount of time, the session can end and the user will be logged out?

[rhyspayne]

I have followed your code exactly but when i click the button to go to log in sceen it doesnt go anywhere. Any help?

[tomaszpepera]

Hi, thanks for vid, could you explain when this block of code is executed?

// ProfileActivity class -> onCreate

== null){
finish();
startActivity(new Intent(this, LoginActivity.class));
}

It means you are not logged in and are in a profile activity -> like deleting an account while logged in?
