copied!<p>A search api is returning me some meta data i.e a url "eventURL" and trackbackurl i.e "trackBack". I am placing the data in the listview, each row containing some data and a unique url and trackback url.When user taps on the row in the listview, a alert dialog is displayed presenting user 2 options. Clicking on option 1 should launch trackback url in a webview while clicking on second opion should launch eventURL in a webview.I have created a WebViewActivity for it,Problem is that my webview is always blank.</p> <p><strong>Main Activity</strong></p> <pre><code>package my.stayactive.plan;
