Google's Answer to the iPhone -- The iPhone is a completely proprietary hardware and software platform released by a single company (Apple), while Android is open source. The Android APIs - At the core of the SDK are the Android API libraries that give developers access to the Android stack. Developer Tools — The SDK includes several developer tools that help you compile and debug your applications, allowing you to turn Android source code into executable applications.
Android Virtual Device Manager and Emulator - Android Emulator is a fully interactive mobile device emulator that features several alternative skins. Complete Documentation - The SDK includes extensive code-level reference information, detailing exactly what is included in each package and class and how to use them. Sample Code — The Android SDK includes a selection of sample apps that demonstrate some of the capabilities available with Android, as well as simple programs that highlight how to use individual API features.
Android Runtime — The runtime is what makes an Android phone an Android phone and not a mobile Linux implementation. As of SDK 1.6 (API level 4), the default value for each attribute is true, so use this node to specify unsupported screen sizes. Each menu definition is stored in a separate file, each containing one menu, in the res/menu folder — the filename then becomes the resource identifier.
Mobile country code and mobile network code (MCC/MNC) — The country, and optionally the network, associated with the SIM card currently used in the device. Smallest Screen Width — The smallest screen dimensions of the device (height and width) specified in the form sw
Available Screen Height — The minimum screen height required to use the contained resources, specified in the form h
Suspend UI updates, threads, or CPU intensive processes // that don't need updating when the activity is not // the active foreground activity. FrameLayout — The simplest of the Layout Managers, the Frame Layout locks each underlying view into its frame. Suspend UI updates, threads, or CPU intensive processes // that don't need updating when the activity is not // the active foreground activity.
In this example, you split the user interface into a series of fragments that represent its component parts: the text input box and the cue list.
