Java / parse error. trying to send from android sdk to parse

Question

configure this for another application a few days ago, and it worked fine, the results were sent successfully to MongoLab. tried to do this again for a new application using the same base code below, but it fails every time.

Any ideas? Thank!

 @Override
  public void onCreate() {
    super.onCreate();

    // Enable Local Datastore.
    Parse.enableLocalDatastore(this);

    // Add your initialization code here
    Parse.initialize(new Parse.Configuration.Builder(getApplicationContext())
            .applicationId("abc123")
            .clientKey(null)
            .server("http://abc123.herokuapp.com/parse/")
    .build()
    );

      ParseObject gameScore = new ParseObject("GameScore");
      gameScore.put("score", 1337);
      gameScore.put("playerName", "Sean Plott");
      gameScore.put("cheatMode", false);
      gameScore.saveInBackground(new SaveCallback() {
          public void done(ParseException e) {
              if (e == null) {
                  Log.i("Parse", "Save Succeeded");
              } else {
                  Log.i("Parse", "Save Failed");
              }
          }
      });

Your client key is null.

Add your client key from the hero settings.
