WhatsApp custom url scheme not working in a Webview

Issue

I am doing webview in android in which I am calling a website link in that website I am calling web.whatsapp.com link. Now this link is working good in desktop as well as mobile view while the same link if I open in webview then showing error i.e. web page is not available for more clear let see the error image

Here is the code of webview android

public class MainActivity extends AppCompatActivity {
    WebView webView;
    ProgressBar bar;

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

        webView = (WebView) findViewById(R.id.webView2);
        bar =(ProgressBar) findViewById(R.id.progressBar2);
        webView.setWebViewClient(new myWebClient());
        webView.loadUrl("http://.../");
        webView.getSettings().setJavaScriptEnabled(true);
        webView.setWebViewClient(new myWebClient());
    }

    public class myWebClient extends WebViewClient{

        @Override
        public void onPageFinished(WebView view, String url) {
            bar.setVisibility(View.GONE);
            view.setVisibility(webView.VISIBLE);
            super.onPageFinished(view, url);
        }

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);
            bar.setVisibility(View.VISIBLE);
        }

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            bar.setVisibility(View.GONE);
            return super.shouldOverrideUrlLoading(view, url);
        }
    }

    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if((keyCode == KeyEvent.KEYCODE_BACK) && webView.canGoBack()){
            webView.goBack();
            return true;
        }

        return super.onKeyDown(keyCode, event);
    }
}

Solution

Try to override shouldOverrideUrlLoading in your web client and use code given below .

@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {

    boolean overrideUrlLoading = false;

    if (url != null && url.startsWith("whatsapp://")) {

        view.getContext().startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url)));

        overrideUrlLoading = true;

    } else {

        view.loadUrl(url);
    }

    return overrideUrlLoading;
}
