# Android OKHttp Interceptor Extension (Optional)

The Authgear Android SDK provides an optional `Okhttp` interceptor which handles everything from refreshing the access token to putting the access token in the header.

## Get the Extension

The extension is included in the SDK. Please refer to the above section for getting the SDK.

## Usage

Configure `OkHttpClient` to use `AuthgearInterceptor` as follows:

```java
Authgear authgear = // Obtain the authgear instance.
OKHttpClient client = new OkHttpClient.Builder()
            .addInterceptor(AuthgearInterceptor(authgear))
            .build()
```

The client would then include the access token in every request and refresh the access token when necessary before the requests.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.authgear.com/get-started/native-mobile-app/android/okhttp-interceptor-extension.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
