【正文】 s full range of puting services and rich functional support have the potential to extend beyond the mobilephone market. Android can be useful for other platforms 。s largely in the form of JavaDocs, making it easy to navigate the many packages in the SDK. The documentation also includes a highlevel Development Guide and links to the broader Android munity. Samples directory XXXXXXX 本科畢業(yè)設(shè) 計(jì)論文 26 The samples subdirectory contains full source code for a variety of applications, including ApiDemo, which exercises many APIs. The sample application is a great place to explore when starting Android application development. Tools directory Contains all of the mandline tools to build Android applications. The most monly employed and useful tool is the adb utility (Android Debug Bridge). USB driver Directory containing the necessary drivers to connect the development environment to an Androidenabled device, such as the G1 or the Android Dev 1 unlocked development phone. These files are only required for developers using the Windows platform. Android applications may be run on a real device or on the Android Emulator, which ships with the Android SDK. Summary: Android is a plete operating environment based upon the Linux174。 Eclipse provides a rich Java environment, including contextsensitive help and code suggestion hints. Once your Java code is piled cleanly, the Android Developer Tools make sure the application is packaged properly, including the file.

A popular technique in Android applications is to link to Google Maps to display an address directly within an application. Support for locationbased services (such as GPS) and accelerometers is also available in the Android software stack, though not all Android devices are equipped with the required hardware. There is also camera support. Historically, two areas where mobile applications have struggled to keep pace with their desktop counterparts are graphics/media, and data storage methods. Android addresses the graphics challenge with builtin support for 2D and 3D graphics, including the OpenGL library. The datastorage burden is eased because 外文資料原文 23 the Android platform includes the popular open source SQLite database. Figure 1 shows a simplified view of the Android software layers. Figure 1.

Android applications are written in the Java programming language, and they run within a virtual machine (VM).

The UI for such devices is often HTMLbased and viewable with a PC or Mac browser. But not every appliance needs to be controlled by a general puting device. Consider a conventional appliance, such as a stove, microwave or bread maker. What if your household appliances were controlled by Android and boasted a color touch screen? With an Android UI on the stovetop, the author might even be able to cook something. In this article, learn about the Android platform and how it can be used for mobile and nonmobile applications. Install the Android SDK and build a simple application. Download the source code for the example application in this article. A brief history of Android The Android platform is the product of the Open Handset Alliance, a group of anizations collaborating to build a better mobile phone. The group, led by Google, includes mobile operators, device handset manufacturers, ponent manufacturers, software solution and platform providers, and marketing panies. From a XXXXXXX 本科畢業(yè)設(shè) 計(jì)論文 22 software development standpoint, Android sits smack in the middle of the open source world. The first Androidcapable handset on the market was the G1 device manufactured by HTC and provisioned on TMobile. The device became available after almost a year of speculation, where the only software development tools available were some incrementally improving SDK releases. As the G1 release date neared, the Android team released SDK and applications began surfacing for the new platform. To spur innovation, Google sponsored two rounds of Android Developer Challenges, where millions of dollars were given to top contest submissions. A few months after the G1, the Android Market was released, allowing users to browse and download applications directly to their phones. Over about 18 months, a new mobile platform entered the public arena.
