 7. Open up the main activity, which can be found in `app/res/layout/activity_main.xml` and switch from its Design to its Text tab if needed. In this file the root element will be a `RelativeLayout` and in there will be a `TextView`. We won't be using the `TextView`, so delete it (or leave it and put a welcome message in it).
