 Now you should see some code that looks familiar-ish! Android layouts using XML, which is very very similar to HTML. You should see already we have a `<RelativeLayout>` and a `<TextView>` tag, with some attributes already there. The thing that looks weird is that all the attributes currently are prefixed with the word `android`.

-In Android we don't use pixels, but instead use `dp` which is a device point. 1 point might be 1 pixel on a really low resolution device, but might be 4 pixels, or even 8 pixels on a newer device. Take a look at this handy guide Android wrote for more information https://developer.android.com/guide/practices/screens_support.html .

-Next, we want to save the following cookie image into our project. You can either google for a cookie image that's free to use, or use ours that we found earlier = http://imgur.com/a/9BXV4 . You need to save it inside your project folder using Windows Explorer or Mac OSX Finder and navigate to the following -> app -> src -> main -> res .

 Because android has different density devices, we usually need to provide different resolution images for all those different devices. If we only provide it in one folder, Android will scale the image for other devices, but this might cause make the image look bad!

 If we want to then use that image in our Android app we can use an attribute `android:src="@drawable/cookie"` - autocomplete will be your friend here!
 
-Because we have a RelativeLayout parent this means we can do some special things to position our cookie on our screen. We can provide an attribute like `android:layout_centerInParent="true"`.
