Register ParseObject before instantiating it

I'm getting this error: java.lang.IllegalArgumentException: You must register this ParseObject subclass before instantiating it.

with code

else {
  ParseUser newUser = new ParseUser();
  newUser.setUsername(username);
  newUser.setPassword(password);
  newUser.setEmail(email);
  newUser.signUpInBackground(new SignUpCallback() {

logcat says the error is on the ParseUser new User line but my imports are as follows

import com.parse.ParseException;
import com.parse.ParseUser;
import com.parse.SignUpCallback;

I have no idea what I did wrong, I thought I followed the tutorial exactly.

this might be too late but you must register the application class (with the initialization code) into the manifest file.

As an application NOT activity.

Sorry, I'm a little late in the response (but I had the same issue).

What caused it for me: playing around with git. I tried doing something experimental, then I rolled back, but it was too far!

How I fixed it:

public class RibbitApplication extends Application {

    @Override
    public void onCreate(){
        super.onCreate();
        // Enable Local Datastore.
        Parse.enableLocalDatastore(this);
        //This is what Parse was complaining about
        Parse.initialize(this, "eCRiFz7HFXwf1Z7ehwaw0x8VkYrAwZvCEfl3N5v5", "UYtdHfYM4C7Td5m0bqwvmIRCjcTOIHPmcCn4DrdW");
    }
}

But more importantly! You need to also update your manifest like Rashan said.

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme"
        android:name=".RibbitApplication">
<!-- name attribute is the important one (just above this line) -->
<!-- rest of the manifest as normal -->

The adding the Java Class as Application worked for me
