        if(TextUtils.isEmpty(userPassword)){

            return;
        }

        if(userPassword.length() < 6){
            showToast("Password too short, enter minimum 6 characters");
            return;
        }

        progressBar.setVisibility(View.VISIBLE);

        //register user
        firebaseAuth.createUserWithEmailAndPassword(userEmail,userPassword)
                .addOnCompleteListener(RegisterActivity.this, new OnCompleteListener<AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {
                        Log.d(TAG, "New user registration: " + task.isSuccessful());

                        if (!task.isSuccessful()) {
                            RegisterActivity.this.showToast("Authentication failed. " + task.getException());
                        } else {
                            RegisterActivity.this.startActivity(new Intent(RegisterActivity.this, MainActivity.class));
                            RegisterActivity.this.finish();
                        }
                    }
                });
    }

    @Override
    protected void onResume() {
        super.onResume();
        progressBar.setVisibility(View.GONE);
    }

    public void showToast(String toastText) {
        Toast.makeText(this, toastText, Toast.LENGTH_SHORT).show();
    }

}

This is the code I have right now in my RegisterActivity.java I watched some tutorials but I can't get whats going wrong. I get loads of 'cannot resolve symbol' errors, and I don't know how to solve that problem. I hope someone can help because I want to go further with this app I'm making :D!

Hope someone can help!

1. The error messages will tell you *exactly* where the problems are and what is wrong, and you'd best read them critically. 2. If you're asking about such errors, it is also *extremely* wise to post all errors here in your question. — Hovercraft Full Of Eels, Jan 08 '21 at 14:36
3. If you're seeing multiple compilation errors, then this suggests that your style of coding needs to be fixed. Don't type a large amount of code and then test it. Instead, if you can't use a modern IDE such as NetBeans or Eclipse (which warns you of compilation issues almost immediately), then it is up to you to compile your code **early and often**, and most importantly **to not add any new code until current compilation issues are fixed**. Else you'll end up with a rat's nest of hard to fix errors. — Hovercraft Full Of Eels, Jan 08 '21 at 14:37
