Android includes an operating system, middleware, and key applications typically required for a mobile device.</p> <p>This porting guide describes the steps necessary to port Android to a new mobile device. Android is designed as a highly-portable, hardware-independent platform based on Linux, and porting the platform to new devices requires little more than porting the Linux kernel and developing the Linux drivers necessary for your device.</p> <p>The current version of this guide describes bringing Android up to "PDA-level" functionality; functionality sufficient to support non-multimedia apps that run on unconnected mobile devices through the standard user interface devices such as keypad and display. Future versions of this guide will cover complete telephony, multi-media and peripheral integration to create a complete mobile device.</p><a name="androidWelcomeIntendedAudience"></a><h2>Intended Audience</h2><p>This porting guide is intended for engineers proficient with running (and writing drivers for) Linux on embedded devices. <p>The guide also assumes you have a target hardware that matches <a href="system_requirements.html">Device Requirements</a> and that you can boot and run a recent (2.6.x) version of the Linux kernelwith at least keypad and display drivers properly installed.</p><a name="androidWelcomeGettingStarted"></a><h2>Getting Started with Android</h2><p>To get started with Android, start with the publicly-available documentation at <a href="http://code.google.com/android/documentation.html">http://code.google.com/android/documentation.html</a>, paying particular attention to <a href="http://code.google.com/android/what-is-android.html">What is Android?</a> and <a href="http://code.google.com/android/intro/index.html">Getting Started with Android</a>.</p><a name="androidWelcomePorting"></a><h2>Porting Android to Your Device</h2><p>Start with the following sections in order to port Android to your target hardware.</p><dl> <dt><a href="system_requirements.html">Device Requirements</a></dt> <dd>What must your device support in order to successfully port Android to it? </dd> <dt><a href="source_setup_guide.html">Setting up a Development Environment </a></dt> <dd>Install necessary packages and retrieve source code through a Git server. <a href="build_system.html">Build System</a> offers a conceptual overview of Android's build system and instructions to affect a simple build.</dd> <dt><a href="bring_up.html">Basic Bring up </a></dt> <dd>Establish core components necessary to your device, such as keymaps / keyboard input and display drivers. </dd> <dt> </dt></dl><p><span class="lh2"><a name="androidFooter"></a></span> </div> </div> <!-- end gc-pagecontent --> </div> <!-- end gooey wrapper --> </div> <!-- end codesearchresults --> <div id="gc-footer" dir="ltr"> <div class="text"> ©2008 Google<!-- - <a href="/">Code Home</a> - <a href="http://www.google.com/accounts/TOS">Site Terms of Service</a> - <a href="http://www.google.com/privacy.html">Privacy Policy</a> - <a href="/more">Site Directory</a> --></div> </div> <!-- end gc-footer --></div><!-- end gc-containter --><script src="http://www.google-analytics.com/ga.js" type="text/javascript"></script><script type="text/javascript"> try { var pageTracker = _gat._getTracker("UA-18071-1"); pageTracker._setAllowAnchor(true); pageTracker._initData(); pageTracker._trackPageview(); } catch(e) {}</script><div id="jd-build-id"> v0.6 - 25 November 2008</div></div></div></div></body></html>⌨️ 快捷键说明
