推送，如何取消订阅获取推送通知？

Question

我正在使用Parse.com。我不希望收到一般性通知，我在onCreate()中尝试过，但没有发生。

ParseApplication

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, "-", "-");
    ParseInstallation.getCurrentInstallation().saveInBackground();

    ParseUser.enableAutomaticUser();
    ParseACL defaultACL = new ParseACL();
    ParseACL.setDefaultACL(defaultACL, true);
  }
}

MainActivity

super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ParsePush.unsubscribeInBackground("", new SaveCallback() {
            @Override
            public void done(ParseException e) {
                if (e == null) {
                    Log.e("com.parse.push", "unscribe");
                } else {
                    Toast.makeText(getApplicationContext(), "Unscribe exception", Toast.LENGTH_SHORT).show();
                }
            }
        });

        ParseAnalytics.trackAppOpenedInBackground(getIntent());
