android push notification with parse doesen't work

I Downloaded from the parse.com the blanck Android Project, then go to parse.com create the App to get the Application & Client ID KEY, put it on ParseApplication class, run the application it's work fine on my device but when I try to send a push notification I get it the messge .... No registered devices

So, whats wrong?

Any ideas?

public class ParseApplication extends Application {

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

// Initialize Crash Reporting.
ParseCrashReporting.enable(this);

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

// Add your initialization code here
Parse.initialize(this,"EVIZ5DUourBOfSWykYZIhy4HFgDC0W","HCmjXHOz3SbHnHLlyQVD4uqOnmXdzAy");
ParsePush.subscribeInBackground("", new SaveCallback() {

    @Override
    public void done(com.parse.ParseException e) {
        // TODO Auto-generated method stub
        if (e== null){
            //log.e;
        } else{
            //log.e;
        }

    }
}); 
ParseUser.enableAutomaticUser();
ParseACL defaultACL = new ParseACL();
// Optionally enable public read access.
// defaultACL.setPublicReadAccess(true);
ParseACL.setDefaultACL(defaultACL, true);
  }
  }
