View Android webview network requests that occurred on page load in Chrome devtools

Question

If you have a webview open in Android, you can inspect it in Chrome devtools. However, I can't open the devtools first, then open the webview to log network requests that occur on page load. Is there a way to log network requests that occur as soon as the webview loads?

Also, refreshing the page behaves differently from the initial load because the page modifies the URL.

Answer 1

You can intercept various components of WebView communication by implementing your own WebViewClient. A short snippet is below:

webView.webViewClient = object : WebViewClient() {

    override fun shouldInterceptRequest(view: WebView,
        request: WebResourceRequest): WebResourceResponse? {
        // Use the `request` object as needed.
    } 
}
