        return result;

    }
}"

If you need any other code ask for it, once I press the sign-in button 4 it displays 'registration failed' yet the empty textbox tag is working once clicked, my app has successfully connected to the database firebase

Answer 2

Here is an example, make sure to add the context:

mAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener(**this**, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    if (task.isSuccessful()) {
\\OnSuccessful
}
