  <p>I am adding my webview in Framelayout. <strong>(I am using addView method for adding my webView)</strong>. Loading webView with loadUrl method. From that page, I clicked on one link and its opening it inside an app which is fine for me. But when I click on Back button, my webview reloads. I don't want my webview to relaod if user goes back.</p>
