| <p>When building a mobile application, it's important that you always test your application on a |
| real device before releasing it to users. This page describes how to set up your development |
| environment and Android-powered device for testing and debugging on the device.</p> |
| |
| <p>You can use any Android-powered device as an environment for running, |
| debugging, and testing your applications. The tools included in the SDK make it easy to install and |
| run your application on the device each time you compile. You can install your application on the |
| device directly from Eclipse or from the command line with ADB. If |
| you don't yet have a device, check with the service providers in your area to determine which |
| Android-powered devices are available.</p> |
| |
| <p>If you want a SIM-unlocked phone, then you might consider a Nexus phone. To purchase a |
| Nexus phone, visit the <a href="https://play.google.com/store/devices">Google Play</a> store.</p> |
| |
| <p class="note"><strong>Note:</strong> When developing on a device, keep in mind that you should |
| still use the <a |
| href="{@docRoot}tools/devices/emulator.html">Android emulator</a> to test your |
| application |
| on configurations that are not equivalent to those of your real device. Although the emulator |
| does not allow you to test every device feature (such as the accelerometer), it does |
| allow you to verify that your application functions properly on different versions of the Android |
| platform, in different screen sizes and orientations, and more.</p> |

| <h2 id="developer-device-options" style="margin-bottom: 0px;">Enabling On-device Developer Options</h2> |
| |
| <img src="/images/tools/dev-options-inmilk.png" alt="" style="float:right;margin-left:30px"> |
| |
| <p>Android-powered devices have a host of developer options that you can |
| access on the phone, which let you:</p> |
| <ul> |
| <li>Enable debugging over USB.</li> |
| <li>Quickly capture bug reports onto the device.</li> |
| <li>Show CPU usage on screen.</li> |
| <li>Draw debugging information on screen such as layout bounds, |
| updates on GPU views and hardware layers, and other information.</li> |
| <li>Plus many more options to simulate app stresses or enable debugging options.</li> |
| </ul> |
| <p>To access these settings, open the <em>Developer options</em> in the |
| system Settings. On Android 4.2 and higher, the Developer options screen is |
| hidden by default. To make it visible, go to |
| <b>Settings > About phone</b> and tap <b>Build number</b> seven times. Return to the previous |
| screen to find Developer options at the bottom.</p> |
| |
| |
| |
| |
| <h2 id="setting-up">Setting up a Device for Development</h2> |
| |
| <p>With an Android-powered device, you can develop and debug your Android applications just as you |
| would on the emulator. Before you can start, there are just a few things to do:</p> |
| |
| <ol> |
| <li>Declare your application as "debuggable" in your Android Manifest. |
| <p>When using Eclipse, you can skip this step, because running your app directly from |
| the Eclipse IDE automatically enables debugging.</p> |
| <p>In the <code>AndroidManifest.xml</code> file, add <code>android:debuggable="true"</code> to |
| the <code><application></code> element.</p> |
| <p class="note"><strong>Note:</strong> If you manually enable debugging in the manifest |
| file, be sure to disable it before you build for release (your published application |
| should usually <em>not</em> be debuggable).</p></li> |
| <li>Enable <strong>USB debugging</strong> on your device. |
| <ul> |
| <li>On most devices running Android 3.2 or older, you can find the option under |
| <strong>Settings > Applications > Development</strong>.</li> |
| <li>On Android 4.0 and newer, it's in <strong>Settings > Developer options</strong>. |
| <p class="note"><strong>Note:</strong> On Android 4.2 and newer, <strong>Developer |
| options</strong> is hidden by default. To make it available, go |
| to <strong>Settings > About phone</strong> and tap <strong>Build number</strong> |
| seven times. Return to the previous screen to find <strong>Developer options</strong>.</p> |
| </li> |
| </ul> |
| </li> |
| <li>Set up your system to detect your device. |
| <ul> |
| <li>If you're developing on Windows, you need to install a USB driver for adb. For an |
| installation guide and links to OEM drivers, see the <a href="{@docRoot}tools/extras/oem-usb.html">OEM USB |
| Drivers</a> document.</li> |
| <li>If you're developing on Mac OS X, it just works. Skip this step.</li> |
| <li>If you're developing on Ubuntu Linux, you need to add a |
| <code>udev</code> rules file that contains a USB configuration for each type of device |
| you want to use for development. In the rules file, each device manufacturer |
| is identified by a unique vendor ID, as specified by the |
| <code>ATTR{idVendor}</code> property. For a list of vendor IDs, see <a |
| href="#VendorIds">USB Vendor IDs</a>, below. To set up device detection on |
| Ubuntu Linux: |
| |
| <ol type="a"> |
| <li>Log in as root and create this file: |
| <code>/etc/udev/rules.d/51-android.rules</code></span>. |
| <p>Use this format to add each vendor to the file:<br/> |
| <code>SUBSYSTEM=="usb", ATTR{idVendor}=="0bb4", MODE="0666", GROUP="plugdev"</code> |
| <br /><br /> |
| |
| In this example, the vendor ID is for HTC. The <code>MODE</code> |
| assignment specifies read/write permissions, and <code>GROUP</code> defines |
| which Unix group owns the device node. </p> |
| |
| <p class="note"><strong>Note:</strong> The rule syntax |
| may vary slightly depending on your environment. Consult the <code>udev</code> |
| documentation for your system as needed. For an overview of rule syntax, see |
| this guide to <a |
| href="http://www.reactivated.net/writing_udev_rules.html">writing udev |
| rules</a>.</p> |
| </li> |
| <li>Now execute:<br/> |
| <code>chmod a+r /etc/udev/rules.d/51-android.rules</code> |
| </li> |
| </ol> |
| </li> |
| </ul> |
| </li> |
| </ol> |
| |
| |
| <p class="note"><strong>Note:</strong> When you connect a device running Android 4.2.2 or higher |
| to your computer, the system shows a dialog asking whether to accept an RSA key that allows |
| debugging through this computer. This security mechanism protects user devices because it ensures |
| that USB debugging and other adb commands cannot be executed unless you're able to unlock the |
| device and acknowledge the dialog. This requires that you have adb version 1.0.31 (available with |
| SDK Platform-tools r16.0.1 and higher) in order to debug on a device running Android 4.2.2 or |
| higher.</p> |
| |
| |
| <p>When plugged in over USB, you can verify that your device is connected by executing <code>adb |
| devices</code> from your SDK {@code platform-tools/} directory. If connected, |
| you'll see the device name listed as a "device."</p> |
| |
| <p>If using Eclipse, run or debug your application as usual. You will be |
| presented with a <b>Device Chooser</b> dialog that lists the available |
| emulator(s) and connected device(s). Select the device upon which you want to |
| install and run the application.</p> |
| |
| <p>If using the <a href="{@docRoot}tools/help/adb.html">Android |
| Debug Bridge</a> (adb), you can issue commands with the <code>-d</code> flag to |
| target your connected device.</p> |
| |
| <h3 id="VendorIds">USB Vendor IDs</h3> |
| |
| <p>This table provides a reference to the vendor IDs needed in order to add USB |
| device support on Linux. The USB Vendor ID is the value given to the |
| <code>ATTR{idVendor}</code> property in the rules file, as described |
| above.</p> |
