# WebAd

**package com.intowow\.sdk**

**public class WebAd**

![](https://1252529651-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LGU_q6Cp7glylaa3ogy%2F-LHc4r11_LGHRxpg0UtE%2F-LHc5oer3kw8os-Llp7G%2Fweb.png?alt=media\&token=b747466a-4d55-485e-94ee-2383841908c5)

### Overview

Web View Ad format helps you to insert the ad into the web view without latency. User can see varies kinds of ads in web view.

### Characteristics

* Zero latency loading in web view.
* Support image and video.
* Video is mute by default, and can be toggled by clicking it.

## Integration

Before showing the ad on the web view, we need to setup the WebAd object. The WebAd object can help intowow SDK interact with the web view.

### 1. Initialize WebAd

Init the WebAd Object and register the object to the web view.

```java
import com.intowow.sdk.WebAd;

private WebView mWebView = new WebView(context);
private WebAd mWebAd = new WebAd(context);

mWebAd.registerWebView(mWebView);
```

### 2. Check shouldInterceptRequest in WebViewClient

Override the **shouldInterceptRequest** and pass the intowow related url to intowow SDK. Our SDK will return the WebResourceResponse back to the WebView to insert the ad source.

```java
mWebView.setWebViewClient(new WebViewClient() {
 @Override
 public WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request) {
     if (request.getUrl() != null && request.getUrl().toString() != null &&
         request.getUrl().toString().indexOf(WebAd.INTOWOW_PREFIX) != -1) {
         WebResourceResponse response = mWebAd.shouldInterceptRequest(view, request);
         if (response != null) {
             return response;
         }
     }
     return super.shouldInterceptRequest(view, request);
 }
});
```

### 3. Destroy WebAd if you no longer need to use it

Please destroy the instance when you no longer need to use it.

```java
if(mWebAd != null) {
    mWebAd.unregisterWebView();
    mWebAd.destroy();
}
```
