Android Firebase Sign In With Email And Password

I have an android app and a Firebase database. The login I've set is with email and password. It works great, but when I try and login with blank email and password the app crashes

Solution 1:

This would help you :)

finalStringEmail= email.getText().toString();
finalStringPassword= password.getText().toString();

if(!TextUtils.isEmpty(Email) && !TextUtils.isEmpty(Password)) {
        mAuth.signInWithEmailAndPassword(email, password).addOnCompleteListener(CustomerLoginActivty.this, newOnCompleteListener<AuthResult>() {
                @OverridepublicvoidonComplete(@NonNull Task<AuthResult> task) {
                    if (!task.isSuccessful()) {

                        Toast.makeText(ThisActivity.this, "sign in error", Toast.LENGTH_SHORT).show();
                    } else
                        mAuth.addAuthStateListener(firebaseAuthListener);
                }
            });
            break;
        }

Solution 2:

Both parameters email and password should not be either null or empty. So if you need to log with blank spaces, make sure you validate the fields and not send a null or an empty to the method signInWithEmailAndPassword
