[@mohammedshamim3575]

Hello Belal Vai... For clearing the Login page or Sign Up page from the Top of the Stack you have to use - intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK); :)

[@christophervradis7285]

Hey man, first of all amazing series of videos. I have a question if you could help me cause i am struggling to find a solution. I am using firebase auth with custom user fields which i save into my db. My problem is with intents. Let's say i am in login screen i type something in email i type something in password, and i dont press login. If i click on register to move on the registration form, everything is fine BUT if i dont click the text to get me in login form, and i just press the back button of my android phone, i get back to login form and the text is still there. That's not much of a problem, my main problem is at login. When i login, i move to my activity, all good, but if i press the button of my android phone to go back, it gets me to login form, text is still there and progressive bar keeps spinning. How do I stop that? Thanks in advance ! =) P.s. if i click login again everything goes fine and i redirect to my activity, i just dont wanna see those texts and that bar spinning and spinning. Lova ya & subscribed.

[@christophervradis7285]
