Really need help on preparing user-to-user push notification code challenge task 2.

I have been working on this for an hour and could really use some help please tell me whats wrong with my code.

LoginActivity.java 
import android.app.Activity;
import android.os.Bundle;
import com.parse.ParseInstallation;
import com.parse.ParseUser;

public class LoginActivity extends Activity {

    /*
     * Some code has been omitted for brevity!
     * This method gets called upon a successful login.
     */

    public void updateParseInstallation() {
        String currentUserId = ParseUser.getCurrentUser().getObjectId();

        ParseInstallation installation;
installation.put("userId", ParseUser.CurrentUserId);

      ParseInstallation.getCurrentInstallation().saveInBackground();

    }

}
InviteActivity.java 
import android.app.Activity;
import android.os.Bundle;
import com.parse.ParseInstallation;
import com.parse.ParseQuery;

public class InviteActivity extends Activity {

    /*
     * Some code has been omitted for brevity!
     * This method gets called when an invitation is sent.
     */

    public void sendPushNotifications(String playerId) {
        ParseQuery<ParseInstallation> pushQuery;

    }
}

You should assign the ParseInstallation.getCurrentInstallation() to the ParseInstallation installation variable:

ParseInstallation installation = ParseInstallation.getCurrentInstallation();

Then you can continue with the put() method.

For the parameters to the put method the currentUserId is already stored above with

String currentUserId = ParseUser.getCurrentUser().getObjectId();

so no need to call "ParseUser.CurrentUserId" and you can just use currentUserId.

Also, if you are just on the task 2 then you can wait to save until task 3 in which case you will again use the ParseInstallation installation variable that the currentUserId was saved in.

Hope that helps.
