title: Firebase setDisplayName of user while creating user Android
body: <p>When creating a user, I want to be able to set his/her display name. How do I do this in Android? Here is an example of what I want to achieve:</p>
  
  <pre><code>mAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener(this, new OnCompleteListener&lt;AuthResult&gt;() {
          @Override
          public void onComplete(@NonNull Task&lt;AuthResult&gt; task) {
              if(task.isSuccessful()){
                  FirebaseUser.getCurrentUser().setDisplayName(mName); //I want to do this
              }
  });
  </code></pre>
  
  <p>Assume all variables have been declared and/or initialized correctly.</p>
