Errors Log: Android Studio Error I encountered & solved
Android Studio problem [SOLVED]: [1] Error Inflate XML in activity Solution 1: 1. Remove <fragment tag from activity xml 2. Rather, replace it with a <FrameLayout 3. In activity class, simply setContentView(R.layout.fragment_register); //here, set the layout as the fragment id Solution 2 (turns out my error is actually this) 1. Check the fragment class 2. My error was I did not inflate the fragment class ------------ *note: any button or function should be made inside onViewCreated [2] Error public void onComplete(@NonNull Task<AuthResult> task) { not succesful Solution: 1. Add "uses INTERNET" in androidmanifest.xml 2. Make sure all variables in class User are accesible (make them public) [3] Attempt to invoke virtual method 'void androidx.navigation.NavController.navigate(int)' on a null object reference Solution: 1. Change navigate method from: navController.navigate(R.id.action_registerFragment2_to_logIn); to: Navigation.findNavController(v).navigate
