从搜索结果google.com打开应用，总是指向Android的WebView首页

Question

I apologize for my English.

I have a problem with redirecting to a subpage of Google results, SMS to WebView Android applications.

Example : The page with the address https://siteadress.pl/category in the Google results opens the WebView application and shows the homepage ( https://siteadress.pl/ ) LOOK PICTURE

Example : A page with the exact product https://siteadress.pl/shop/productxyz in Google results also opens the WebView application and shows the homepage. Why?

The link ( https://siteadress.pl/shop/productxyz ) from the sms message also opens the WebView application and shows the main page.

I want to point to the exact page of the application in WebView, not the homepage. :(

Thanks for help :)

Answer 1

The solution is you need to handle app link first, get the correct link and then load that link into your WeView:

Uri data = getIntent().getData();

if (data != null) {
    String url = data.toString();
    webView.loadUrl(url);
} else {
    webView.loadUrl("https://siteadress.pl/");
}

Answer 2

Done! This version in "Kotlin" work:

val url = intent.data.toString()

if (URLUtil.isValidUrl(url)) {
    webView.loadUrl(url)
} else {
    webView.loadUrl("https://siteadress.pl/")
}

Thanks for help :) ufff
