• You can simply set visibility of that webview. – Upendra Shah Commented Apr 26, 2018 at 5:11

As per ments on question, I am putting a better term for closing the web view - going back to previous screen. You can do this as follows for Android and iOS :

Android :

finish()  

iOS :

If you are using navigation controller :

self.navigationController?.popViewController(animated: true)  

If you are presenting web view controller :

self.dismiss(animated: true, pletion: nil)  

The key is to check that url in the delegate function of web view.

Android :

    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        if (url.equals("your_url")) {
            finish()
            return false;
        } else {
            return true;
        }
    }  

iOS :

func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebViewNavigationType) -> Bool {
        if request.url?.absoluteString == "your_url" {
            self.navigationController?.popViewController(animated: true)
            // If controller is presented -  self.dismiss(animated: true, pletion: nil)  
            return false
        }

        return true
    }

You can use shouldOverrideUrlLoading

Give the host application a chance to take over the control when a new url is about to be loaded in the current WebView. If WebViewClient is not provided, by default WebView will ask Activity Manager to choose the proper handler for the url. If WebViewClient is provided, return true means the host application handles the url, while return false means the current WebView handles the url.

Notes:

• This method is not called for requests using the POST "method".
• This method is also called for subframes with non-http schemes, thus it is strongly disadvised to unconditionally call loadUrl(String) with the request's url from inside the method and then return true, as this will make WebView to attempt loading a non-http url, and thus fail.

Here is the sample demo

public class MainActivity extends AppCompatActivity {

    WebView myWebView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        myWebView = findViewById(R.id.myWebView);
        myWebView.setWebViewClient(new MyWebViewClient());
        myWebView.getSettings().setJavaScriptEnabled(true);
        myWebView.loadUrl("https://stackoverflow./users/7666442/nilesh-rathod?tab=topactivity");

    }


    public class MyWebViewClient extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            if (url.equals("https://stackoverflow./users/7666442/nilesh-rathod?tab=profile")) {

                finish() ;
                Toast.makeText(MainActivity.this, "URL DETECTED", Toast.LENGTH_SHORT).show();
                // perform your action here
                return true;
            } else {
                view.loadUrl(url);
                return true;
            }
        }
    }


}

In iOS you would now be using Safari sfview so directly picking up a URL is blocked for security hence the only universal solution you can apply in both Android and iOS apps is deep linking.

You can trigger to close the safari sf view when you reach that specific URL using deep link.

Google deep link and follow the examples.

Use this can help you

  myWebView.destroy();
  myWebView = null;
