this is my code :
TextView aboutL1 = (TextView) findViewById(R.id.aboutL2);
aboutL1.setText(Html.fromHtml("This app is open source.<br>The source code is hosted on <a href=\"http://herp.com/derp\">Github</a> "));
Linkify.addLinks(aboutL1, Linkify.ALL);
The word github appears as a link but nothing happens when I click on the link ...
