** Easiest way (if available) is to register the event handler via the layout xml file.
* '''Layout''': We'll look at several types of layouts in detail next week.
* '''Fragment''': created using an XML layout file that looks like a sub-layout and behaves like a sub-activity. We'll look at fragments next week.
* '''Content Provider''': One way for an application to provide access to data it holds. It's one form of IPC usually used for more standard types of data. See a list of tutorials at the [http://developer.android.com/guide/topics/providers/content-providers.html bottom of this page]. We'll also look at them more closely after the break.
* '''Menu''': Used to be a critical part of any android application until the menu button's been removed from Android tablets and later phones. Now is still used but isn't as prevalent.
