TheAndroid SDKprovides the tools and APIs necessary to begin developing applications on the Android platform using the Java programming language.Features Application frameworkenabling reuse and replacement of ponents Dalvik virtual machineoptimized for mobile devices Integrated browserbased on the open sourceWebKitengine Optimized graphicspowered by a custom 2D graphics library。 3D graphics based on the OpenGL ES specification (hardware acceleration optional) SQLitefor structured data storage Media supportfor mon audio, video, and still image formats (MPEG4, , MP3, AAC, AMR, JPG, PNG, GIF) GSM Telephony(hardware dependent) Bluetooth, EDGE, 3G, and WiFi(hardware dependent) Camera, GPS, pass, and accelerometer(hardware dependent) Rich development environmentincluding a device emulator, tools for debugging, memory and performance profiling, and a plugin for the Eclipse IDEApplicationsAndroid will ship with a set of core applications including an client, SMS program, calendar, maps, browser, contacts, and others. All applications are written using the Java programming language.Application FrameworkBy providing an open development platform, Android offers developers the ability to build extremely rich and innovative applications. Developers are free to take advantage of the device hardware, access location information, run background services, set alarms, add notifications to the status bar, and much, much more.Developers have full access to the same framework APIs used by the core applications. The application architecture is designed to simplify the reuse of ponents。 any application can publish its capabilities and any other application may then make use of those capabilities (subject to security constraints enforced by the framework). This same mechanism allows ponents to be replaced by the user.Underlying all applications is a set of services and systems, including: A rich and extensible set ofViewsthat can be used to build an application, including lists, grids, text boxes, buttons, and even an embeddable web browser Content Providersthat enable applications to access data from other applications (such as Contacts), or to share their own data AResource Manager, providing access to noncode resources such as localized strings, graphics, and layout files ANotification Managerthat enables all applications to display custom alerts in the status bar AnActivity Managerthat manages the lifecycle of applications and provides a mon navigation backstackFor more details and a walkthrough of an application, see theNotepad Tutorial.LibrariesAndroid includes a set of C/C++ libraries used by various ponents of the Android system. These capabilities are exposed to developers through the Android application framework. Some of the core libraries are listed below: System C library a BSDderived implementation of the standard C system library (libc), tuned for embedded Linuxbased devices Media Libraries based on PacketVideo39。s OpenCORE。 the libraries support playback and recording of many popular audio and video formats, as well as static image files, including MPEG4, , MP3, AAC, AMR, JPG, and PNG Surface Manager manages access to the display subsystem and seamlessly posites 2D and 3D graphic layers from multiple applications LibWebCore a modern web browser engine which powers both the Android browser and an embeddable web view SGL the underlying 2D graphics engine 3D libraries an implementation based on OpenGL ES APIs。 the libraries use either hardware 3D acceleration (where available) or the included, highly optimized 3D software rasterizer FreeType bitmap and vector font rendering SQLite a powerful and lightweight relational database engine available to all applicationsAndroid RuntimeAndroid includes a set of core libraries that provides most of the functionality available in the core libraries of the Java programming language.Every Android application runs in its own process, with its own instance of the Dalvik virtual machine. Dalvik has been written so that a device can run multiple VMs efficiently. The Dalvik VM executes files in the Dalvik Executable (.dex) format which is optimized for minimal memory footprint. The VM is registerbased, and runs classes piled by a Java language piler that have been transformed into the .dex format by the included dx tool.The Dalvik VM relies on the Linux kernel for underlying functionality such as threading and lowlevel memory management.Linux KernelAndroid relies on Linux version for core system services such as security, memory management, process management, network stack, and driver model. The kernel also acts as an abstraction layer between the hardware and the rest of the software stack.android 開發(fā)幫助賈斯廷安德森什么是Android?Android 是一個(gè)專門針對移動(dòng)設(shè)備的軟件集，它包括一個(gè)操作系統(tǒng)，中間件和一些重要的應(yīng)用程序。Beta版的Android SDK 提供了在Android平臺(tái)上使用JAVA語言進(jìn)行Android應(yīng)用開發(fā)必須的工具和API接口。特性 應(yīng)用程序框架支持組件的重用與替換 Dalvik 虛擬機(jī)專為移動(dòng)設(shè)備優(yōu)化 集成的瀏覽器基于開源的webkit 引擎 優(yōu)化的圖形庫包括定制的2D圖形庫，3D圖形庫基于OpenGL ES （硬件加速可選） SQLite 用作結(jié)構(gòu)化的數(shù)據(jù)存儲(chǔ) 多媒體支持包括常見的音頻、視頻和靜態(tài)圖像格式（如MPEG4, , MP3, AAC, AMR, JPG, PNG, GIF） GSM 電話技術(shù)（依賴于硬件） 藍(lán)牙 Bluetooth, EDGE, 3G, 和wifi （依賴于硬件） 照相機(jī)，GPS，指南針，和加速度計(jì)（accelerometer） （依賴于硬件） 豐富的開發(fā)環(huán)境包括設(shè)備模擬器，調(diào)
