A property list (PList) file is a special XML file used by iOS applications to store data for the application, which will change frequently. This file stores the data outside of the main app bundle so any changes will not require the application to be rebuilt. You can think of the Plist file as being similar to a config file in .NET applications.

A settings bundle file has the name Settings.bundle and resides in the top level directory of your solution. Settings bundles are used by Settings App Interface to implement a set of pages to navigate the application's settings.

An Android Activity at its simplest form is a screen in an Android application. Since Android's architecture doesn't rely on a single application instance, an application can be seen as a conglomeration of one or more activities. If you are new to Android, it will be important to understand the concept of an activity as it might be the most important concept in Android development.

Use the Android Fragment file type to add a new fragment to your application. Unlike the iOS platform, which serves a very finite number of device types, Android can run on more devices and in more shapes and sizes than I can think of. As of Android 3.0, the concept of the Fragment was introduced to help service flexible user interface designs for the many screen sizes found on modern devices. You can think of a Fragment as a user interface module that can be mixed and matched with other modules to assemble screens that are aesthetically pleasing and contain a logical workflow, even on very different devices. What's really great about fragments is that the developer doesn't have to lay out the various modules to work with every screen size—you just need to provide the fragments and the activity will decide which fragments to use automatically!

An Android Layout will add a new layout to your application. For more information on layouts, please refer to Chapter 3, Working with Xcode and the Android SDK.

An Android View will add a new view to your application. For more information on views, please refer to Chapter 3, Working with Xcode and the Android SDK.

In order for your Android application to work with remote notifications, you must configure a Broadcast Receiver to listen for the intents that the Google Services Framework will publish when it receives a message from the Google Cloud Messaging service.Note

For more information on using the Google Services Framework and Google Cloud Messaging in Xamarin.Android projects, refer to Xamarin's documentation on how to implement these features at http://developer.xamarin.com/guides/cross-platform/application_fundamentals/notifications/android/remote_notifications_in_android/.
