This page describes how to set up your development 24environment and Android-powered device for testing and debugging on the device.</p> 25 26<p>You can use any Android-powered device as an environment for running, 27debugging, and testing your applications. The tools included in the SDK make it easy to install and 28run your application on the device each time you compile. You can install your application on the 29device directly from Eclipse or from the command line with ADB. If 30you don't yet have a device, check with the service providers in your area to determine which 31Android-powered devices are available.</p> 32 33<p>If you want a SIM-unlocked phone, then you might consider a Nexus phone. To find a place 34to purchase the Nexus S and other Android-powered devices, visit <a 35href="http://www.google.com/phone/detail/nexus-s">google.com/phone</a>.</p> 36 37<p class="note"><strong>Note:</strong> When developing on a device, keep in mind that you should 38still use the <a 39href="{@docRoot}tools/devices/emulator.html">Android emulator</a> to test your 40application 41on configurations that are not equivalent to those of your real device. Although the emulator 42does not allow you to test every device feature (such as the accelerometer), it does 43allow you to verify that your application functions properly on different versions of the Android 44platform, in different screen sizes and orientations, and more.</p> 45 46 47<h2 id="setting-up">Setting up a Device for Development</h2> 48 49<p>With an Android-powered device, you can develop and debug your Android applications just as you 50would on the emulator. Before you can start, there are just a few things to do:</p> 51 52<ol> 53 <li>Declare your application as "debuggable" in your Android Manifest. 54 <p>When using Eclipse, you can skip this step, because running your app directly from 55the Eclipse IDE automatically enables debugging.</p> 56 <p>In the <code>AndroidManifest.xml</code> file, add <code>android:debuggable="true"</code> to 57the <code><application></code> element.</p> 58 <p class="note"><strong>Note:</strong> If you manually enable debugging in the manifest 59 file, be sure to disable it before you build for release (your published application 60should usually <em>not</em> be debuggable).</p></li> 61 <li>Enable <strong>USB debugging</strong> on your device. 62 <ul> 63 <li>On most devices running Android 3.2 or older, you can find the option under 64 <strong>Settings > Applications > Development</strong>.</li> 65 <li>On Android 4.0 and newer, it's in <strong>Settings > Developer options</strong>. 66 <p class="note"><strong>Note:</strong> On Android 4.2 and newer, <strong>Developer 67 options</strong> is hidden by default. To make it available, go 68 to <strong>Settings > About phone</strong> and tap <strong>Build number</strong> 69 seven times. Return to the previous screen to find <strong>Developer options</strong>.</p> 70 </li> 71 </ul> 72 </li> 73 <li>Set up your system to detect your device. 74 <ul> 75 <li>If you're developing on Windows, you need to install a USB driver for adb. For an 76installation guide and links to OEM drivers, see the <a href="{@docRoot}tools/extras/oem-usb.html">OEM USB 77Drivers</a> document.</li> 78 <li>If you're developing on Mac OS X, it just works. Skip this step.</li> 79 <li>If you're developing on Ubuntu Linux, you need to add a 80<code>udev</code> rules file that contains a USB configuration for each type of device 81you want to use for development. In the rules file, each device manufacturer 82is identified by a unique vendor ID, as specified by the 83<code>ATTR{idVendor}</code> property. For a list of vendor IDs, see <a 84href="#VendorIds">USB Vendor IDs</a>, below. To set up device detection on 85Ubuntu Linux: 86 87 <ol type="a"> 88 <li>Log in as root and create this file: 89 <code>/etc/udev/rules.d/51-android.rules</code></span>. 90 <p>Use this format to add each vendor to the file:<br/> 91 <code>SUBSYSTEM=="usb", ATTR{idVendor}=="0bb4", MODE="0666", GROUP="plugdev"</code> 92 <br /><br /> 93 94 In this example, the vendor ID is for HTC. The <code>MODE</code> 95assignment specifies read/write permissions, and <code>GROUP</code> defines 96which Unix group owns the device node. </p> 97 98 <p class="note"><strong>Note:</strong> The rule syntax 99may vary slightly depending on your environment. Consult the <code>udev</code> 100documentation for your system as needed. For an overview of rule syntax, see 101this guide to <a 102href="http://www.reactivated.net/writing_udev_rules.html">writing udev 103rules</a>.</p> 104 </li> 105 <li>Now execute:<br/> 106 <code>chmod a+r /etc/udev/rules.d/51-android.rules</code> 107 </li> 108 </ol> 109 </li> 110 </ul> 111 </li> 112</ol> 113 114 115<p class="note"><strong>Note:</strong> When you connect a device running Android 4.2.2 or higher 116to your computer, the system shows a dialog asking whether to accept an RSA key that allows 117debugging through this computer. This security mechanism protects user devices because it ensures 118that USB debugging and other adb commands cannot be executed unless you're able to unlock the 119device and acknowledge the dialog. This requires that you have adb version 1.0.31 (available with 120SDK Platform-tools r16.0.1 and higher) in order to debug on a device running Android 4.2.2 or 121higher.</p> 122 123 124<p>When plugged in over USB, you can verify that your device is connected by executing <code>adb 125devices</code> from your SDK {@code platform-tools/} directory. If connected, 126you'll see the device name listed as a "device."</p> 127 128<p>If using Eclipse, run or debug your application as usual. You will be 129presented with a <b>Device Chooser</b> dialog that lists the available 130emulator(s) and connected device(s). Select the device upon which you want to 131install and run the application.</p> 132 133<p>If using the <a href="{@docRoot}tools/help/adb.html">Android 134Debug Bridge</a> (adb), you can issue commands with the <code>-d</code> flag to 135target your connected device.</p> 136 137<h3 id="VendorIds">USB Vendor IDs</h3> 138 139<p>This table provides a reference to the vendor IDs needed in order to add USB 140device support on Linux. The USB Vendor ID is the value given to the 141<code>ATTR{idVendor}</code> property in the rules file, as described 142above.</p> 143 144<table> 145 <tr> 146 <th>Company</th><th>USB Vendor ID</th></tr> 147 <tr> 148 <td>Acer</td> 149 <td><code>0502</code></td> 150 </tr> 151 <tr> 152 <td>ASUS</td> 153 <td><code>0b05</code></td> 154 </tr> 155 <tr> 156 <td>Dell</td> 157 <td><code>413c</code></td> 158 </tr> 159 <tr> 160 <td>Foxconn</td> 161 <td><code>0489</code></td> 162 </tr> 163 <tr> 164 <td>Fujitsu</td> 165 <td><code>04c5</code></td> 166 </tr> 167 <tr> 168 <td>Fujitsu Toshiba</td> 169 <td><code>04c5</code></td> 170 </tr> 171 <tr> 172 <td>Garmin-Asus</td> 173 <td><code>091e</code></td> 174 </tr> 175 <tr> 176 <td>Google</td> 177 <td><code>18d1</code></td> 178 </tr> 179 <tr> 180 <td>Haier</td> 181 <td><code>201E</code></td> 182 </tr> 183 <tr> 184 <td>Hisense</td> 185 <td><code>109b</code></td> 186 </tr> 187 <tr> 188 <td>HTC</td> 189 <td><code>0bb4</code></td> 190 </tr> 191 <tr> 192 <td>Huawei</td> 193 <td><code>12d1</code></td> 194 </tr> 195 <tr> 196 <td>K-Touch</td> 197 <td><code>24e3</code></td> 198 </tr> 199 <tr> 200 <td>KT Tech</td> 201 <td><code>2116</code></td> 202 </tr> 203 <tr> 204 <td>Kyocera</td> 205 <td><code>0482</code></td> 206 </tr> 207 <tr> 208 <td>Lenovo</td> 209 <td><code>17ef</code></td> 210 </tr> 211 <tr> 212 <td>LG</td> 213 <td><code>1004</code></td> 214 </tr> 215 <tr> 216 <td>Motorola</td> 217 <td><code>22b8</code></td> 218 </tr> 219 <tr> 220 <td>MTK</td> 221 <td><code>0e8d</code></td> 222 </tr> 223 <tr> 224 <td>NEC</td> 225 <td><code>0409</code></td> 226 </tr> 227 <tr> 228 <td>Nook</td> 229 <td><code>2080</code></td> 230 </tr> 231 <tr> 232 <td>Nvidia</td> 233 <td><code>0955</code></td> 234 </tr> 235 <tr> 236 <td>OTGV</td> 237 <td><code>2257</code></td> 238 </tr> 239 <tr> 240 <td>Pantech</td> 241 <td><code>10a9</code></td> 242 </tr> 243 <tr> 244 <td>Pegatron</td> 245 <td><code>1d4d</code></td> 246 </tr> 247 <tr> 248 <td>Philips</td> 249 <td><code>0471</code></td> 250 </tr> 251 <tr> 252 <td>PMC-Sierra</td> 253 <td><code>04da</code></td> 254 </tr> 255 <tr> 256 <td>Qualcomm</td> 257 <td><code>05c6</code></td> 258 </tr> 259 <tr> 260 <td>SK Telesys</td> 261 <td><code>1f53</code></td> 262 </tr> 263 <tr> 264 <td>Samsung</td> 265 <td><code>04e8</code></td> 266 </tr> 267 <tr> 268 <td>Sharp</td> 269 <td><code>04dd</code></td> 270 </tr> 271 <tr> 272 <td>Sony</td> 273 <td><code>054c</code></td> 274 </tr> 275 <tr> 276 <td>Sony Ericsson</td> 277 <td><code>0fce</code></td> 278 </tr> 279 <tr> 280 <td>Teleepoch</td> 281 <td><code>2340</code></td> 282 </tr> 283 <tr> 284 <td>Toshiba</td> 285 <td><code>0930</code></td> 286 </tr> 287 <tr> 288 <td>ZTE</td> 289 <td><code>19d2</code></td> 290 </tr> 291</table> 292
