It provides headers and 64libraries that allow you to build activities, handle user input, use hardware sensors, 65access application resources, and more, when programming in C or C++. If you write 66native code, your applications are still packaged into an .apk file and they still run 67inside of a virtual machine on the device. The fundamental Android application model 68does not change.</p> 69 70Using native code does not result in an automatic performance increase, 71but always increases application complexity. If you have not run into any limitations 72using the Android framework APIs, you probably do not need the NDK. 73<p>Read <a href="<?cs var:toroot ?>sdk/ndk/overview.html">What is the NDK?</a> 74to get an understanding of what the NDK offers and whether 75it will be useful to you. 76</p> 77<p> 78The NDK is designed for use <em>only</em> in conjunction with the 79Android SDK, so if you have not already installed the latest Android SDK, please 80do so before downloading the NDK. 81</p> 82 83<p>Select the download package that is appropriate for your development 84computer. </p> 85 86 <table class="download"> 87 <tr> 88 <th>Platform</th> 89 <th>Package</th> 90 <th>Size</th> 91 <th>MD5 Checksum</th> 92 </tr> 93 <tr> 94 <td>Windows</td> 95 <td> 96 <a href="http://dl.google.com/android/ndk/<?cs var:ndk.win_download ?>"><?cs var:ndk.win_download ?></a> 97 </td> 98 <td><?cs var:ndk.win_bytes ?> bytes</td> 99 <td><?cs var:ndk.win_checksum ?></td> 100 </tr> 101 <tr class="alt-color"> 102 <td>Mac OS X (intel)</td> 103 <td> 104 <a href="http://dl.google.com/android/ndk/<?cs var:ndk.mac_download ?>"><?cs var:ndk.mac_download ?></a> 105 </td> 106 <td><?cs var:ndk.mac_bytes ?> bytes</td> 107 <td><?cs var:ndk.mac_checksum ?></td> 108 </tr> 109 <tr> 110 <td>Linux 32/64-bit (x86)</td> 111 <td> 112 <a href="http://dl.google.com/android/ndk/<?cs var:ndk.linux_download ?>"><?cs var:ndk.linux_download ?></a> 113 </td> 114 <td><?cs var:ndk.linux_bytes ?> bytes</td> 115 <td><?cs var:ndk.linux_checksum ?></td> 116 </tr> 117 </table> 118 119 <?cs else ?><?cs if:android.whichdoc == "online" ?> 120 121 <?cs if:sdk.preview ?> 122 <p>Welcome developers!

Instead, you will use the Android SDK and AVD Manager to 152 keep your development environment up-to-date. </li> 153 </ul> 154 <p style="margin-top:0">If you are currently using the Android 1.6 SDK, you 155 do not need to install the new SDK, because your existing SDK already 156 includes the Android SDK and AVD Manager tool. To develop against Android 157 2.0.1, for example, you can just download the Android 2.0.1 platform (and 158 updated SDK Tools) into your existing SDK.
