# Getting Started

To initialize the SDK, add the following to your Application subclass; including your [Publishable Key](https://docs.guestlogix.io/quick-start#publishable-key) in the `initialize` method. 

You should also include the UI SDK and initialize that as well. However in order to properly utilize the UI SDK a payment provider is required. Currently we only support [Stripe](https://stripe.com) as a payment provider so be sure to include that as well.

```java
public class MyApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        
        Traveler.initialize("YOUR_KEY_GOES_HERE", getApplicationContext());
        TravelerUI.initialize(new StripePaymentProvider());
    }
}

```

For this you must subclass the `Application` class and set it as the application in your `AndroidManifest.xml`. If you haven't done so already, create a class like above in your main application's project and be sure to add it to the application tag in your manifest like below

```markup
    <application
            android:name=".application.MyApplication"
            ...>
    </applcation>
```
