Create a User?

Well you should show us your code ;)

Well first of all you dont have any code in else block, which should create user.

Can you copy error which pops up in logcat?

hi. I had the same problem. It has been solved a bit lower in the questions for this tutorial (https://teamtreehouse.com/forum/register-parseobject-before-instantiating-it).

For me, the problem was caused because I was initializing parse in my MainActivity onCreate(). It should be done in the application instead.

So create a new class (call it RibbitApplication) and pop in the following code (changing it where relevant to your values e.g. YourApplication = RibbitApplication):

public class YourApplication extends Application { @Override public void onCreate() { super.onCreate(); Parse.initialize(this, "id","key"); } }

Now you need to declare it to the manifest as follows (changing where relevant):

<application android:name="com.you.yourapp.YourApplication"
