Answer 1

I think @Sk Maniruddin is asking how to open another app from a webpage. And the solution to that is using an intent, as the link.

  <a href="intent://scan/#Intent;scheme=zxing;package=com.google.zxing.client.android;end"> Take a QR code </a>

for more information you can look at the doc: https://developer.chrome.com/multidevice/android/intents#example

Firstly set your onclik method of button in html like this.

<input type="submit" name="submit" id="submit_id" onclick="click.performClick();" />

enable javascript your webview

webView.getSettings().setJavaScriptEnabled(true);

after that you can detect this click by this code:

webView.addJavascriptInterface(new Object() {
            @JavascriptInterface
            public void performClick() {// detected click 
                Intent i = new Intent(FromActivity.This, DestinationActivity.class);
                    startActivity(i);

            }

        }, "click");
