<p>When building mobile applications, it's vital to test them on real
devices prior to releasing them to users. This page covers what you need to know,
including the types of devices that you can use, and how to set one up for
developing and debugging.</p>
<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 <a
href="{@docRoot}guide/developing/eclipse-adt.html#RunningOnDevice">directly from
Eclipse</a> or <a href="{@docRoot}guide/developing/other-ide.html#RunningOnDevice">from the
command line</a>. 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>
<h2 id="devices">Available Devices</h2>
<p>Here are some options for obtaining devices capable of testing your applications.</p>
<h3 id="consumer">Consumer devices</h3>
<p>It's likely that one of your local mobile carriers offers an Android-powered device.
Any Android-powered device (even one bought from your mobile carrier) is a perfectly good
device for running and testing your own Android applications.
You can write applications using the Android SDK and then install them
directly onto the device for testing.</p>
<p>Check with the service providers in your area to determine which Android-powered
devices are available.</p>
<p>Be aware that consumer devices are not designed to allow system image updates by the
user. If you're interested in manually updating the device with custom system images, then
you'll need a developer device such as the <a href="#dev-phone-1">Android Dev Phone 1</a>.</p>
<h3 id="dev-phone-1">Android Dev Phone 1</h3>

<p>The Android Dev Phone 1 is a SIM-unlocked and hardware-unlocked device that
is designed for advanced developers. The device ships with a system image that
is fully compatible with Android 1.0, so you can rely on it when developing your
applications. You can use any SIM in the device and can flash custom Android
builds that will work with the unlocked bootloader. Unlike the bootloader on
retail devices, the bootloader on the Android Dev Phone 1 does not enforce
signed system images. The Android Dev Phone 1 should also appeal to developers
who live in geographies where local mobile carriers do not currently offer Android-powered devices. </p>
<p>To purchase an Android Dev Phone 1 device, you must first register as an
Android developer on the Android Market site, if you haven't done so already.
Once you've logged into your developer account on Android Market, you can
purchase the device by following the link to "Development phones." To accommodate demand,
there is a limit of 1 device per developer account, for now.</p>
<p>The device currently costs $399 (USD) (including free shipping in the US),
and is available for purchase in 18 international markets, including the
US, UK, Germany, Japan, India, Canada, France, Taiwan, Spain, Australia,
Singapore, Switzerland, Netherlands, Austria, Sweden, Finland, Poland, and
Hungary. We will continue to expand this program into new geographies over
time. Check this page for updated information.</p>
<p>Android Dev Phone 1 devices are <em>not</em> intended for
non-developer end-users. Because the device can be configured with system
software not provided by or supported by Google or any other company, end-users
operate these devices at their own risk.</p>
<p>Note that your Android Dev Phone 1 will not receive automated
over-the-air (OTA) updates for the system image. System updates must be flashed manually.
See the HTC site for a guide to <a href="http://www.htc.com/www/support/android/adp.html">Flashing
your Android Dev Phone with a Factory System Image</a>.</p>
<p>For full device specs and more information about obtaining an Android Dev
Phone 1 device, see the <a href="http://market.android.com/publish">Android
Market</a> site.</p>
<p>If you want a SIM-unlocked phone, then you might consider either an Android Dev Phone or the
Google Nexus One. Both are SIM-unlocked so that you can use them on any GSM network using a SIM
card. The Android Dev Phones also feature an unlocked bootloader so you can install custom system
images (great for developing and installing custom versions of the Android platform). To purchase a
Nexus One, visit <a href="http://www.google.com/phone">google.com/phone</a>. To purchase an Android
Dev Phone, see the <a href="http://market.android.com/publish">Android Market</a> site
(requires a developer account).</p>

<p>Before you can run your application on the Android Emulator,
you <strong>must</strong> create an Android Virtual Device (AVD).
An AVD is a configuration that specifies the Android platform to be used on the emulator.

Devices</a> document, but if you just want to get started, follow the simple guide below to
create an AVD.</p>

<h2 id="AVD">Creating an AVD</h2>
<p>Unless you'll be running your application on device hardware,
you need to launch an emulator upon which you will install your application.
An instance of the Android emulator runs a specific Android platform with specific device configuration
settings. The platform and configuration is defined with an Android Virtual Device (AVD).
So before you can launch your emulator, you must define an AVD.</p>
<p>An Android Virtual Device (AVD) is a device configuration for the emulator that
allows you to model real world devices. In order to run an instance of the emulator, you must create
an AVD.</p>
<p>If you'll be running your application on device hardware, please read about
<a href="{@docRoot}guide/developing/device.html">Developing On a Device</a> instead.</p>
<p>To create an AVD using the SDK tools:</p>
<ol>
<li><strong>Create an AVD</strong>
<ol>
<li>Open a command-line and navigate to your SDK package's
<code>tools/</code> directory.</li>
<li>First, you need to select a "deployment target." To view available targets, execute:
<pre>android list targets</pre>
<p>This will output a list of available Android targets, such as:</p>
<pre>
id:1
Name: Android 1.1
Type: platform
API level: 2
Skins: HVGA (default), HVGA-L, HVGA-P, QVGA-L, QVGA-P
id:2
Name: Android 1.5
Type: platform
API level: 3
Skins: HVGA (default), HVGA-L, HVGA-P, QVGA-L, QVGA-P
</pre>
<p>Find the target that matches the Android platform upon which you'd like
to run your application. Note the integer value of the <code>id</code> &mdash;
you'll use this in the next step.</p>
</li>
<li>Create a new AVD using your selected deployment target:
<pre>android create avd --name <em>&lt;your_avd_name&gt;</em> --target <em>&lt;target_ID&gt;</em></pre>
<li>Next, you'll be asked whether you'd like to create a custom hardware profile.
If you respond "yes," you'll be presented with a series of prompts to define various aspects of the
device hardware (leave entries blank to use default values, which are shown in brackets). Otherwise,
press return to use all default values ("no" is the default).</li>
</li>
</ol>
<li>Navigate to your SDK's <code>tools/</code> directory and execute the {@code android}
tool with no arguments:
<pre>android</pre>
<p>This will launch the SDK and AVD Manager GUI.</p>
</li>
<li>In the <em>Virtual Devices</em> panel, you'll see a list of existing AVDs. Click
<strong>New</strong>
to create a new AVD.</li>
<li>Fill in the details for the AVD.
<p>Give it a name, a platform target, an SD card size, and
a skin (HVGA is default).</p>
<p class="note"><strong>Note:</strong> Be sure to define
a target for your AVD that satisfies your application's build target (the AVD
platform target must have an API Level equal to or greater than the API Level that your
application compiles against).</p>
</li>

<h3 id="RunningOnEmulator">Running on the emulator</h3>
<p>Before you can run your application on the Android Emulator,
you must <a href="#AVD">create an AVD</a>.</p>
<p>To run your application:</p>
<ol>
<li><strong>Open the SDK and AVD Manager and launch a virtual device</strong></li>
<p>From your SDK's <code>tools/</code> directory, execute the {@code android} tool with no
arguments:
<pre>android</pre>
<p>In the <em>Virtual Devices</em> view, select an AVD and click <strong>Start</strong>.</p>
</li>
<li><strong>Launch an emulator</strong></li>
<p>From your SDK's <code>tools/</code> directory, launch an emulator
using an existing AVD (created above):
<pre>emulator -avd <em>&lt;your_avd_name&gt;</em></pre>
<p>An instance of the emulator will now launch, running the target and configuration
defined by your AVD.</p>
</li>
<li><strong>Install your application</strong>
<p>From your SDK's <code>tools/</code> directory, install the .apk on the emulator:
<pre>adb install <em>/path/to/your/application</em>.apk</pre>
<p>If there is more than one emulator running, you must specify the emulator upon which to install
the application, by its serial number, with the <code>-s</code> option. For example:</p>
<pre>adb -s emulator-5554 install /my/project/path/myapp.apk</pre>
</li>
<li><strong>Open your application</strong>
<p>In the emulator, open the list of available applications to find
and open your application.</p>
<p>From your SDK's <code>tools/</code> directory, install the {@code .apk} on the
emulator:
<pre>adb install <em>&lt;path_to_your_bin&gt;</em>.apk</pre>
<p>Your APK file (signed with either a release or debug key) is in your project {@code bin/}
directory after you <a href="#Building">build your application</a>.</p>
<p>If there is more than one emulator running, you must specify the emulator upon which to
install the application, by its serial number, with the <code>-s</code> option. For example:</p>

<p>To see a list of available device serial numbers, execute {@code adb devices}.</p>

virtual device again from the SDK and AVD Manager. Sometimes when you install an Activity for the
first time, it won't show up in the application launcher or be accessible by other
applications. This is because the package manager usually examines manifests
completely only on emulator startup.</p>
<p class="note"><strong>Tip:</strong> If you have only one emulator running,
<p>Be certain to create multiple AVDs upon which to test your application. You should have one AVD
for each platform and screen type with which your application is compatible. For
instance, if your application compiles against the Android 1.5 (API Level 3) platform, you should
create an AVD for each platform equal to and greater than 1.5 and an AVD for each <a
href="{@docRoot}guide/practices/screens_support.html">screen type</a> you support, then test
your application on each one.</p>
<p class="note"><strong>Tip:</strong> If you have <em>only one</em> emulator running,
you can build your application and install it on the emulator in one simple step.
Navigate to the root of your project directory and use Ant to compile the project
with <em>install mode</em>:
<code>ant install</code>. This will build your application, sign it with the debug key,
and install it on the currently running emulator.
If there is more than one emulator currently running
when using the <code>install</code> command, it will fail &mdash; it can't select between the
multiple emulators.</p>

<h3 id="RunningOnDevice">Running on a device</h3>
<p>Before you can run your application on a device, you must perform some basic setup for your
device:</p>
<ul>
<li>Declare your application as debuggable in your manifest</li>
<li>Enable USB Debugging on your device</li>
<li>Ensure that your development computer can detect your device when connected via USB</li>
</ul>
<p>Read <a href="{@docRoot}guide/developing/device.html#setting-up">Setting up a Device for
Development</a> for more information.</p>
<p>Once your device is set up and connected via USB, navigate to your
SDK's <code>tools/</code> directory and install the <code>.apk</code> on the device:
<pre>adb -d install <em>/path/to/your/app</em>.apk</pre>
<p>The {@code -d} flag specifies that you want to use the attached device (in case you also
have an emulator running).</p>
