## Public methods

### shouldInterceptRequest

Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public WebResourceResponse shouldInterceptRequest (WebResourceRequest request)
```

Notify the host application of a resource request and allow the application to return the data. If the return value is `null`, the Service Worker will continue to load the resource as usual. Otherwise, the return response and data will be used.

**Note:** This method is called on a thread other than the UI thread so clients should exercise caution when accessing private data or the view system.

<br />

| Parameters ||
|---|---|
| `request` | `WebResourceRequest`: Object containing the details of the request. <br /> |

| Returns ||
|---|---|
| `https://developer.android.com/reference/android/webkit/WebResourceResponse` | A `https://developer.android.com/reference/android/webkit/WebResourceResponse` containing the response information or `null` if the WebView should load the resource itself. <br /> |
