H5AdsWebViewClient

Kotlin |Java

@RequiresApi(api = VERSION_CODES.LOLLIPOP)
public final class H5AdsWebViewClient extends WebViewClient

java.lang.Object
↳	android.webkit.WebViewClient
	↳	com.google.android.gms.ads.h5.H5AdsWebViewClient

用于拦截和处理 H5 广告请求的 WebViewClient。如需使用此功能，请将其设置为包含将发出 H5 广告请求的 Web 应用的 WebView 的客户端。

重要提示：此 WebViewClient 不能用于多个 WebView。每个将支持 H5 广告的新 WebView 都必须使用新的 H5AdsWebViewClient。

示例代码：

public void onCreate(Bundle savedInstanceState) {
  ...

  // Initialize early to reduce latency on the session's first ad request.
  MobileAds.initialize(this);

  WebView myWebView = findViewById(R.id.my_webview);

  // JavaScript must be enabled.
  WebSettings settings = myWebView.getSettings();
  settings.setJavaScriptEnabled(true);

  H5AdsWebViewClient h5Client = new H5AdsWebViewClient(this, myWebView);

  // (Optional) any existing WebViewClient
  WebViewClient myClient = ...;
  h5Client.setDelegateWebViewClient(myClient);

  webView.setWebViewClient(h5Client);
}
