title: Layout-land folder is not changing the display on an emulator
body: <p>I'm having a problem making my emulator switch to a landscape layout, as shown by the screenshot below i have defined a landscape layout folder, with the files in it. I'm not sure if the problem is to do with the fact they are fragments but i'm unsure. </p>
