Are you sure you have already searched for the same problem?

Some people open new issues but they didn't search for something similar or for the same issue. Please, search for it using the GitHub issue search box or on the official inappwebview.dev website, or, also, using Google, StackOverflow, etc. before posting a new one. You may already find an answer to your problem!

If this is really a new issue, then thank you for raising it. I will investigate it and get back to you as soon as possible. Please, make sure you have given me as much context as possible! Also, if you didn't already, post a code example that can replicate this issue.

In the meantime, you can already search for some possible solutions online! Because this plugin uses native WebView, you can search online for the same issue adding android WebView [MY ERROR HERE] or ios WKWebView [MY ERROR HERE] keywords.

Following these steps can save you, me, and other people a lot of time, thanks!

@pichillilorenzo Basically, Truecaller launch a intent- truecallersdk://truesdk/web_verify?requestNonce=0f6a5b72-365f-4a86-ac5b-d71581a75ef2&partnerKey=FOXvM3bc9658bc7f8420498b7337e61a995ca&partnerName=Some&lang=en&title=Sign%20in&skipOption=useAnotherNum

how to handle this, and make login successful, and return to exisitng web page.

we cannot always invoke truecaller SDK from webview, as the user may or may not have TrueCaller installed in app. One way which worked for me was to skip this TrueCaller verification invocation, on website which do it before loggin in the user. we can override shouldOverrideUrlLoading the and add following code to skip TrueCallerSDK URI

String url = request.getUrl().toString();
if (url.startsWith("truecallersdk://")) {
                   isTrueCallerSDKCalled = true;
                   return true;
                }
