browser - Android block ads in webview

Question

I want to implement a mechanism in a custom webview client (without JavaScript injection) that can block ads. Is a way I can catch ads and replace them with other ads from a trusted source? Thanks

Answer 1

In your custom WebViewClient, you can override the function shouldInterceptRequest(WebView, WebResourceRequest).

From Android docs:

Notify the host application of a resource request and allow the application to return the data.

So the general idea is to check if the request is coming from an ad URL (plenty of black list filters out there), then return a "fake" resource that isn't the ad.
