-<p>The Android SDK includes a mobile device emulator -- a virtual mobile device
-that runs on your computer. The emulator lets you prototype, develop, and test
-Android applications without using a physical device. </p>
-
-<p>The Android emulator mimics all of the hardware and software features
-of a typical mobile device, except that it can not receive or place actual phone
-calls. It provides a variety of navigation and control keys, which you can "press"
-using your mouse or keyboard to generate events for your application. It also
-provides a screen in which your application is displayed, together with any other
-Android applications running. </p>
-
-<p>To let you model and test your application more easily, the emulator supports
-Android Virtual Device (AVD) configurations. AVDs let you specify the Android
-platform that you want to run on the emulator, as well as the hardware options
-and emulator skin files tht you want to use. Once your application is running on
-the emulator, it can use the services of the Android platform to invoke other
-applications, access the network, play audio and video, store and retrieve data,
-notify the user, and render graphical transitions and themes. </p>
-
-<p>The emulator also includes a variety of debug capabilities, such as a console
-from which you can log kernel output, simulate application interrupts (such as
-arriving SMS messages or phone calls), and simulate latency effects and dropouts
-on the data channel.</p>

-<h2>Overview</h2>
-
-<p>The Android emulator is a QEMU-based application that provides a virtual ARM
-mobile device on which you can run your Android applications. It runs a full
-Android system stack, down to the kernel level, that includes a set of
-preinstalled applications (such as the dialer) that you can access from your
-applications. You can choose what version of the Android system you want to
-run in the emulator by configuring AVDs, and you can also customize the
-mobile device skin and key mappings. When launching the emulator and at runtime,
-you can use a variety of commands and options to control the its behaviors.
-</p>
-
-<p>The Android system image distributed in the SDK contains ARM machine code for
-the Android Linux kernel, the native libraries, the Dalvik VM, and the various
-Android package files (such as for for the Android framework and preinstalled
-applications). The emulator's QEMU layers provide dynamic binary translation of
-the ARM machine code to the OS and processor architecture of your development
-machine. </p>
-
-<p>Adding custom capabilities to the underlying QEMU services, the Android
-emulator supports many hardware features likely to be found on mobile devices,
-including: </p>
-
-<ul>
- <li>An ARMv5 CPU and the corresponding memory-management unit (MMU)</li>
- <li>A 16-bit LCD display</li>
- <li>One or more keyboards (a Qwerty-based keyboard and associated Dpad/Phone
-buttons)</li>
- <li>A sound chip with output and input capabilities</li>
- <li>Flash memory partitions (emulated through disk image files on the
-development machine)</li>
- <li>A GSM modem, including a simulated SIM Card</li>
-</li>
-</ul>
-
-<p>The sections below provide more information about the emulator and how to use
-it for developing Android applications.</p>
-
-<a name="starting"></a>
-
-<h2>Starting and Stopping the Emulator</h2>
-
-<p>During development and testing of your application, you install and run your
-application in the Android emulator. You can launch the emulator as a standalone
-application, from a command line, or you can use it as part of your Eclipse
-development environment. In either case, you specify the AVD configuration to
-load and any startup options you want to use, as described in this document.
-</p>
-
-<p>You can run your application on a single instance of the emulator or,
-depending on your needs, you can start multiple emulator instances and run your
-application in more than one emulated device. You can use the emulator's
-built-in commands to simulate GSM phone calling or SMS between emulator
-instances, and you can set up network redirections that allow emulators to send
-data to one another. For more information, see <a href="#telephony">Telephony
-Emulation</a>, <a href="#sms">SMS Emulation</a>, and
-<a href="#emulatornetworking">Emulator Networking</a></p>
-
-<p>To start an instance of the emulator from the command line, change to the
-<code>tools/</code> folder of the SDK. Enter <code>emulator</code> command
-like this: </p>
-
-<pre>emulator -avd <avd_name></pre>
-
-<p>This initializes the emulator and loads an AVD configuration (see the next
-section for more information about AVDs). You will see the emulator window
-appear on your screen. </p>
-
-<p>If you are working in Eclipse, the ADT plugin for Eclipse installs your
-application and starts the emulator automatically, when you run or debug
-the application. You can specify emulator startup options in the Run/Debug
-dialog, in the Target tab. When the emulator is running, you can issue
-console commands as described later in this document.</p>
-
-<p>If you are not working in Eclipse, see <a href="#apps">Installing Applications
-on the Emulator</a> for information about how to install your application.</p>
-
-<p>To stop an emulator instance, just close the emulator's window.</p>
-
-<a name="controlling"></a>
-
-<a name="avds"></a>
-
-<h2>Android Virtual Devices and the Emulator</h2>
-
-<p>To use the emulator, you first must create one or more AVD configurations. In each
-configuration, you specify an Android platform to run in the emulator and the set of hardware
-options and emulator skin you want to use. Then, when you launch the emulator, you specify
-the AVD configuration that you want to load. </p>
-
-<p>To specify the AVD you want to load when starting the emulator, you use the
-<code>-avd</code> argument, as shown in the previous section. </p>
-
-<p>Each AVD functions as an independent device, with its own private storage for
-user data, SD card, and so on. When you launch the emulator with an AVD configuration,
-it automatically loads the user data and SD card data from the AVD directory. By default,
-the emulator stores the user data, SD card data, and cache in the AVD directory.</p>
-
-<p>To create and manage AVDs you use the android tool, a command-line utility
-included in the SDK. For complete information about how to set up AVDs, see <a
-href="{@docRoot}guide/developing/tools/avd.html">Android Virtual Devices</a>.</p>
-
-<h2>Controlling the Emulator</h2>
-
-<p>You can use emulator <a href="#startup-options">startup options</a> and <a
-href="#console">console commands</a> to control the behaviors and
-characteristics of the emulated environment itself.
-</p>
+<p>
+<p>The Android SDK includes a mobile device emulator — a virtual mobile device
+that runs on your computer. The emulator lets you develop and test
+Android applications without using a physical device.</p>
<p>When the emulator is running, you can interact with the emulated mobile
device just as you would an actual mobile device, except that you use your mouse
-pointer to "touch" the touchscreen and your keyboard keys to
-"press" the simulated device keys. </p>

+<h2 id="startup-options">Emulator Startup Options</h2>
-<h2> Emulator Startup Options</h2>
<p>The emulator supports a variety of options that you can specify
when launching the emulator, to control its appearance or behavior.
Here's the command-line usage for launching the emulator with options: </p>
<pre>emulator -avd <avd_name> [-<option> [<value>]] ... [-<qemu args>]</pre>
-<p>The table below summarizes the available options.</p>
+<p class="table-caption"><strong>Table 1.</strong>Emulator startup options</p>
<table>
<tr>
<td>See comments for <code>-skin</code>, above.</td></tr>
</table>
-<a name="diskimages"></a>
-
-<h2>Working with Emulator Disk Images</h2>
-
-<p>The emulator uses mountable disk images stored on your development machine to
-simulate flash (or similar) partitions on an actual device. For example, it uses
-disk image containing an emulator-specific kernel, the Android system, a
-ramdisk image, and writeable images for user data and simulated SD card.</p>
-
-<p>To run properly, the emulator requires access to a specific set of disk image
-files. By default, the Emulator always looks for the disk images in the
-private storage area of the AVD in use. If no images exist there when
-the Emulator is launched, it creates the images in the AVD directory based on
-default versions stored in the SDK. </p>
-
-<p class="note"><strong>Note:</strong> The default storage location for
-AVDs is in <code>~/.android/avd</code> on OS X and Linux, <code>C:\Documents and
-Settings\<user>\.android\</code> on Windows XP, and
-<code>C:\Users\<user>\.android\</code>
-on Windows Vista.</p>
-
-<p>To let you use alternate or custom versions of the image files, the emulator
-provides startup options that override the default locations and filenames of
-the image files. When you use the options, the emulator searches for the image
-file under the image name or location that you specify; if it can not locate the
-image, it reverts to using the default names and location.</p>
-
-<p>The emulator uses three types of image files: default image files, runtime
-image files, and temporary image files. The sections below describe how to
-override the location/name of each type of file. </p>
-
-<a name="defaultimages"></a>
-<h3>Default Images</h3>
-
-<p>When the emulator launches but does not find an existing user data image in
-the active AVD's storage area, it creates a new one from a default version
-included in the SDK. The default user data image is read-only. The image
-files are read-only.</p>
-
-<p>The emulator provides the <code>-system <dir></code> startup option to
-let you override the location under which the emulator looks for the default
-user data image. </p>
-
-<p>The emulator also provides a startup option that lets you override the name
-of the default user data image, as described in the table below. When you use the
-option, the emulator looks in the default directory, or in a custom location
-(if you specified <code>-system <dir></code>). </p>

-<a name="runtimeimages"></a>
-<h3>Runtime Images: User Data and SD Card</h3>
-
-<p>At runtime, the emulator reads and writes data on two disk images: a
-user-data image and (optionally) an SD card image. This emulates the user-data
-partition and removable storage media on actual device. </p>
-
-<p>The emulator provides a default user-data disk image. At startup, the emulator
-creates the default image as a copy of the system user-data image (user-data.img),
-described above. The emulator stores the new image with the files of the active AVD.</p>
-
-<!--
-<p>The emulator provides a startup option, <code>-datadir <dir></code>,
-that you can use to override the location under which the emulator looks for the runtime
-image files. </p>
--->
-
-<p>The emulator provides startup options to let you override the actual names and storage
-locations of the runtime images to load, as described in the table below. When you use one
-of these options, the emulator looks for the specified file(s) in the current working directory,
-in the AVD directory, or in a custom location (if you specified a path with the filename). </p>

-path the image, relative to the current working directory. If you supply a filename only,
-the emulator looks for the file in the current working directory. If the file at <code><filepath></code> does
-not exist, the emulator creates an image from the default userdata.img, stores it under the name you
-specified, and persists user data to it at shutdown. </td>

-</tr>
-
-</table>
-
-<h4>User-Data Image</h4>
-
-<p>Each emulator instance uses a writeable user-data image to store user- and
-session-specific data. For example, it uses the image to store a unique user's
-installed application data, settings, databases, and files. </p>
-
-<p>At startup, the emulator attempts to load a user-data image stored during
-a previous session. It looks for the file in the current working directory,
-in the AVD directory as described above, and at the custom location/name
-that you specified at startup. </p>
-
-<ul>
-<li>If it finds a user-data image, it mounts the image and makes it available
-to the system for reading/writing of user data. </li>
-<li>If it does not find one, it creates an image by copying the system user-data
-image (userdata.img), described above. At device power-off, the system persists
-the user data to the image, so that it will be available in the next session.
-Note that the emulator stores the new disk image at the location/name that you
-specify in <code>-data</code> startup option.</li>
-</ul>
-
-<p class="note"><strong>Note:</strong> Because of the AVD configurations used in the emulator,
-each emulator instance now gets its own dedicated storage. There is no need
-to use the <code>-d</code> option to specify an instance-specific storage area.</p>
-
-<h4>SD Card</h4>
-
-<P>Optionally, you can create a writeable disk image that the emulator can use
-to simulate removeable storage in an actual device. For information about how to create an
-emulated SD card and load it in the emulator, see <a href="#sdcard">SD Card Emulation</a></p>
-
-<p>You can also use the android tool to automatically create an SD Card image
-for you, when creating an AVD. For more information, see <a
-href="{@docRoot}guide/developing/tools/avd.html#options">Command-line options for AVDs</a>.
-
-<a name="temporaryimages"></a>
-<h3>Temporary Images</h3>
-
-<p>The emulator creates two writeable images at startup that it deletes at
-device power-off. The images are: </p>
-
-<ul>
- <li>A writable copy of the Android system image</li>
- <li>The <code>/cache</code> partition image</li>
-</ul>
-
-<p>The emulator does not permit renaming the temporary system image or
-persisting it at device power-off. </p>
-
-<p>The <code>/cache</code> partition image is initially empty, and is used by
-the browser to cache downloaded web pages and images. The emulator provides an
-<code>-cache <file></code>, which specifies the name of the file at which
-to persist the <code>/cache</code> image at device power-off. If <code><file>
-</code> does not exist, the emulator creates it as an empty file. </p>
-
-<p>You can also disable the use of the cache partition by specifying the
-<code>-nocache</code> option at startup. </p>
-
-
-<a name="emulatornetworking"></a>
-<h2>Emulator Networking</h2>
-
-<p>The emulator provides versatile networking capabilities that you can use to
-set up complex modeling and testing environments for your application. The
-sections below introduce the emulator's network architecture and capabilities.
-</p>
-
-<a name="networkaddresses"></a>
-<h3>Network Address Space</h3>
-
-<p>Each instance of the emulator runs behind a virtual router/firewall service
-that isolates it from your development machine's network interfaces and settings
-and from the internet. An emulated device can not see your development machine
-or other emulator instances on the network. Instead, it sees only that it is
-connected through Ethernet to a router/firewall.</p>
-
-<p>The virtual router for each instance manages the 10.0.2/24 network address
-space — all addresses managed by the router are in the form of
-10.0.2.<xx>, where <xx> is a number. Addresses within this space are
-pre-allocated by the emulator/router as follows:</p>
-
-<table>
+<h2>Emulator Keyboard Mapping</h2>

-</table>
-
-<p>Note that the same address assignments are used by all running emulator
-instances. That means that if you have two instances running concurrently on
-your machine, each will have its own router and, behind that, each will have an
-IP address of 10.0.2.15. The instances are isolated by a router and can
-<em>not</em> see each other on the same network. For information about how to
-let emulator instances communicate over TCP/UDP, see <a
-href="#connecting">Connecting Emulator Instances</a>.</p>
-
-<p>Also note that the address 127.0.0.1 on your development machine corresponds
-to the emulator's own loopback interface. If you want to access services running
-on your development machine's loopback interface (a.k.a. 127.0.0.1 on your
-machine), you should use the special address 10.0.2.2 instead.</p>
-
-<p>Finally, note that each emulated device's pre-allocated addresses are
-specific to the Android emulator and will probably be very different on real
-devices (which are also very likely to be NAT-ed, i.e., behind a
-router/firewall)</p>
-
-<a name="networkinglimitations"></a>
-<h3>Local Networking Limitations</h3>
-
-<p>Each emulator instance runs behind a virtual router, but unlike an actual
-device connected to a physical router, the emulated device doesn't have access
-to a physical network. Instead it runs as part of a normal application on your
-development machine. This means that it is subject to the same networking
-limitations as other applications on your machine:</p>
-
-<ul>
- <li>Communication with the emulated device may be blocked by a firewall
-program running on your machine.</li>
- <li>Communication with the emulated device may be blocked by another
-(physical) firewall/router to which your machine is connected.</li>
-</ul>
-
-<p>The emulator's virtual router should be able to handle all outbound TCP and
-UDP connections/messages on behalf of the emulated device, provided your
-development machine's network environment allows it to do so. There are no
-built-in limitations on port numbers or ranges except the one imposed by your
-host operating system and network.</p>
-
-<p>Depending on the environment, the emulator may not be able to support other
-protocols (such as ICMP, used for "ping") might not be supported. Currently, the
-emulator does not support IGMP or multicast. </p>
-

-<p>To communicate with an emulator instance behind its virtual router, you need
-to set up network redirections on the virtual router. Clients can then connect
-to a specified guest port on the router, while the router directs traffic
-to/from that port to the emulated device's host port. </p>
-
-<p>To set up the network redirections, you create a mapping of host and guest
-ports/addresses on the the emulator instance. There are two ways to set up
-network redirections: using emulator console commands and using the ADB tool, as
-described below. </p>
-<a name="consoleredir"></a>
-<h4>Setting up Redirections through the Emulator Console</h4>
-
-<p>Each emulator instance provides a control console the you can connect to, to
-issue commands that are specific to that instance. You can use the
-<code>redir</code> console command to set up redirections as needed for an
-emulator instance. </p>
-
-<p>First, determine the console port number for the target emulator instance.
-For example, the console port number for the first emulator instance launched is
-5554. Next, connect to the console of the target emulator instance, specifying
-its console port number, as follows: </p>
-
-<pre><code>telnet localhost 5554</code></pre>
-
-<p>Once connected, use the <code>redir</code> command to work with redirections.
-To add a redirection, use:</a>. </p>
-
-<pre><code>add <protocol>:<host-port>:<guest-port></code>
-</pre>
-
-<p>where <code><protocol></code> is either <code>tcp</code> or <code>udp</code>,
-and <code><host-port></code> and <code><guest-port></code> sets the
-mapping between your own machine and the emulated system, respectively. </p>
-
-<p>For example, the following command sets up a redirection that will handle all
-incoming TCP connections to your host (development) machine on 127.0.0.1:5000
-and will pass them through to the emulated system's 10.0.2.15:6000.:</p>
-
-<pre>redir add tcp:5000:6000</pre>
-
-<p>To delete a redirection, you can use the <code>redir del</code> command. To
-list all redirections for a specific instance, you can use <code>redir
-list</code>. For more information about these and other console commands, see
-<a href="#console">Using the Emulator Console</a>. </p>
-
-<p>Note that port numbers are restricted by your local environment. this typically
-means that you cannot use host port numbers under 1024 without special
-administrator privileges. Also, you won't be able to set up a redirection for a
-host port that is already in use by another process on your machine. In that
-case, <code>redir</code> generates an error message to that effect. </p>
-
-<a name="adbredir"></a>
-<h4>Setting Up Redirections through ADB</h4>
-
-<p>The Android Debug Bridge (ADB) tool provides port forwarding, an alternate
-way for you to set up network redirections. For more information, see <a
-href="{@docRoot}guide/developing/tools/adb.html#forwardports">Forwarding Ports</a> in the ADB
-documentation.</p>
-
-<p>Note that ADB does not currently offer any way to remove a redirection,
-except by killing the ADB server.</p>
-
-<a name="dns"></a>
-<h3>Configuring the Emulator's DNS Settings</h3>
-
-<p>At startup, the emulator reads the list of DNS servers that your system is
-currently using. It then stores the IP addresses of up to four servers on this
-list and sets up aliases to them on the emulated addresses 10.0.2.3, 10.0.2.4,
-10.0.2.5 and 10.0.2.6 as needed. </p>
-
-<p>On Linux and OS X, the emulator obtains the DNS server addresses by parsing
-the file <code>/etc/resolv.conf</code>. On Windows, the emulator obtains the
-addresses by calling the <code>GetNetworkParams()</code> API. Note that this
-usually means that the emulator ignores the content of your "hosts" file
-(<code>/etc/hosts</code> on Linux/OS X, <code>%WINDOWS%/system32/HOSTS</code>
- on Windows).</P>
-
-<p>When starting the emulator at the command line, you can also use the
-<code>-dns-server <serverList></code> option to manually specify the
-addresses of DNS servers to use, where <serverList> is a comma-separated
-list of server names or IP addresses. You might find this option useful if you
-encounter DNS resolution problems in the emulated network (for example, an
-"Unknown Host error" message that appears when using the web browser).</p>
-
-<a name="proxy"></a>
-<h3>Using the Emulator with a Proxy</h3>
-
-<p>If your emulator must access the Internet through a proxy server, you can use
-the <code>-http-proxy <proxy></code> option when starting the emulator, to
-set up the appropriate redirection. In this case, you specify proxy information
-in <code><proxy></code> in one of these formats:</p>
-
-<pre>http://<machineName>:<port></pre>
-
-<p>or</p>
-
-<pre>http://<username>:<password>@<machineName>:<port></pre>
-
-<p>The <code>-http-proxy</code> option forces the emulator to use the specified
-HTTP/HTTPS proxy for all outgoing TCP connections. Redirection for UDP is not
-currently supported.</p>
-
-<p>Alternatively, you can define the environment variable
-<code>http_proxy</code> to the value you want to use for
-<code><proxy></code>. In this case, you do not need to specify a value for
-<code><proxy></code> in the <code>-http-proxy</code> command — the
-emulator checks the value of the <code>http_proxy</code> environment variable at
-startup and uses its value automatically, if defined. </p>
-
-<p>You can use the <code>-debug-proxy</code> option to diagnose proxy
-connection problems.</p>
-
-<a name="connecting"></a>
-<h3>Interconnecting Emulator Instances</h3>
-
-<p>To allow one emulator instance to communicate with another, you must set up
-the necessary network redirections as illustrated below. </p>
-
-<p>Assume that your environment is</p>
-
-<ul>
- <li>A is you development machine</li>
- <li>B is your first emulator instance, running on A</li>
- <li>C is your second emulator instance, running on A too</li>
-</ul>
-
-<p>and you want to run a server on B, to which C will connect, here is how you
-could set it up: </p>
-
-<ol>
- <li>Set up the server on B, listening to
-<code>10.0.2.15:<serverPort></code></li>
- <li>On B's console, set up a redirection from
-<code>A:localhost:<localPort></code> to <code>
-B:10.0.2.15:<serverPort></code></li>
- <li>On C, have the client connect to 10.0.2.2:<localPort></code></li>
-</ol>
-
-<p>For example, if you wanted to run an HTTP server, you can select
-<code><serverPort></code> as 80 and <code><localPort></code> as
-8080:</p>
-
-<ul>
- <li>B listens on 10.0.2.15:80</li>
- <li>On B's console, issue <code>redir add tcp:8080:80</code></li>
- <li>C connects to 10.0.2.2:8080</li>
-</ul>
-
-<a name="calling"></a>
-<h3>Sending a Voice Call or SMS to Another Emulator Instance</h3>
-
-<p>The emulator automatically forwards simulated voice calls and SMS messages from one instance to another. To send a voice call or SMS, you use the dialer application and SMS application (if available) installed on one emulator </p>
-
-<p>To initiate a simulated voice call to another emulator instance:</p>
-<ol>
-<li>Launch the dialer application on the originating emulator instance.</li>
-<li>As the number to dial, enter the console port number of the instance you'd like to call. You can determine
- the console port number of the target instance by checking its window title, where the
- console port number is reported as "Android Emulator (<port>). </li>
-<li>Press "Dial". A new inbound call appears in the target emulator instance. </li>
-</ol>
-
-<p>To send an SMS message to another emulator instance, launch the SMS application (if available). Specify the console port number of the target emulator instance as as the SMS address, enter the message text, and send the message. The message is delivered to the target emulator instance. </p>
-
-<p>You can also connect to an emulator instance's console to simulate an incoming voice call or SMS. For more information, see <a href="#telephony">Telephony Emulation</a> and <a href="#sms">SMS Emulation</a>.
-
-<a name="console"></a>
-
-<h2>Using the Emulator Console</h2>
-
-<p>Each running emulator instance includes a console facility that lets you dynamically query and control the simulated device environment. For example, you can use the console to dynamically manage port redirections and network characteristics and simulate telephony events. To access the console and enter commands, you use telnet to connect to the console's port number. </p>
-<p>To connect to the console of any running emulator instance at any time, use this command: </p>
-
-<pre>telnet localhost <console-port></pre>
-
-<p>An emulator instance occupies a pair of adjacent ports: a console port and an adb port. The port numbers differ by 1, with the adb port having the higher port number. The console of the first emulator instance running on a given machine uses console port 5554 and adb port 5555. Subsequent instances use port numbers increasing by two — for example, 5556/5557, 5558/5559, and so on. Up to 16 concurrent emulator instances can run a console facility. </p>
-
-<p>To connect to the emulator console, you must specify a valid console port. If multiple emulator instances are running, you need to determine the console port of the emulator instance you want to connect to. You can find the instance's console port listed in the title of the instance window. For example, here's the window title for an instance whose console port is 5554:</p>
-
-<p><code>Android Emulator (5554)</code></p>
-
-<p>Alternatively, you can use the <code>adb devices</code> command, which prints a list of running emulator instances and their console port numbers. For more information, see <a href="{@docRoot}guide/developing/tools/adb.html#devicestatus">Querying for Emulator/Device Instances</a> in the adb documentation.</p>
-
-<p class="note">Note: The emulator listens for connections on ports 5554-5587 and accepts connections only from localhost.</p>
-
-<p>Once you are connected to the console, you can then enter <code>help [command]</code> to see a list of console commands and learn about specific commands. </p>
-
-<p>To exit the console session, use <code>quit</code> or <code>exit</code>.</p>
-
-<p>The sections below describe the major functional areas of the console.</p>
-
-<a name="portredirection"></a>
-
-<h3>Port Redirection</h3>
-<p>You can use the console to add and remove port redirections while the emulator is running. After connecting to the console, you can manage port redirections in this way:</p>
-<pre>redir <list|add|del> </pre>
-
-<p>The <code>redir</code> command supports the subcommands listed in the table below. </p>

-<h3>Geo Location Provider Emulation</h3>
-
-<p>The console provides commands to let you set the geo position used by an emulator emulated device. You can use the <code>geo</code> command to send a simple GPS fix to the emulator, without needing to use NMEA 1083 formatting. The usage for the command is: </p>
-
-<pre>geo <fix|nmea></pre>
-
-<p>The <code>geo</code> command supports the subcommands listed in the table below. </p>

-</tr>
-</table>
-
-<p>You can issue the <code>geo</code> command to fix the GPS location as soon as an emulator instance is running. The emulator creates a mock location provider that sends it to GPS-aware applications as soon as they start and register location listeners. Any application can query the location manager to obtain the current GPS fix for the emulated device by calling:
-
-<pre>LocationManager.getLastKnownLocation("gps")</pre>
-
-<p>For more information about the Location Manager, see {@link android.location.LocationManager} and its methods.</p>

-<h3>Terminating an Emulator Instance</h3>
-
-<p>You can terminate an emulator instance through the console, using the <code>kill</code> command.</p>

-
-<h2>Using Emulator Skins</h2>
-
-<p>The Android SDK includes several Emulator skins that you can use to control the resolution and density of the emulated device's screen. To select a specific skin for running the emulator, create an AVD that uses that skin. Please do not use deprecated emulator options such as <code>-skin</code> to control the skin used by an emulator instance. For more information about AVDs, see <a
-href="{@docRoot}guide/developing/tools/avd.html">Android Virtual Devices</a>. </p>
-
-
-<a name="multipleinstances"></a>
-
-<h2>Running Multiple Emulator Instances</h2>
-
-<p>Through the AVDs configurations used by the emulator, you can run multiple
-instances of the emulator concurrently, each with its own AVD configuration and
-storage area for user data, SD card, and so on. You no longer need to use the
-<code>-d</code> option when launching the emulator, to point to an
-instance-specific storage area. </p>
-
-<a name="apps"></a>
-
-<h2>Installing Applications on the Emulator</h2>
-
-<p>If you don't have access to Eclipse or the ADT Plugin, you can install
-your application on the emulator <a href="{@docRoot}guide/developing/tools/adb.html#move">using
-the adb utility</a>. Before installing the application, you need to package it
-in a .apk file using the <a href="{@docRoot}guide/developing/tools/aapt.html">Android Asset Packaging Tool</a>.
-Once the application is installed, you can start the emulator from the command
-line, as described in this document, using any startup options necessary.
-When the emulator is running, you can also connect to the emulator instance's
-console to issue commands as needed.</p>
-
-<p>As you update your code, you periodically package and install it on the emulator.
-The emulator preserves the application and its state data across restarts,
-in a user-data disk partition. To ensure that the application runs properly
-as you update it, you may need to delete the emulator's user-data partition.
-To do so, start the emulator with the <code>-wipe-data</code> option.
-For more information about the user-data partition and other emulator storage,
-see <a href="#diskimages">Working with Emulator Disk Images</a>.</p>

-<h2>SD Card Emulation</h2>
-
-<p>You can create a disk image and then load it to the emulator at startup, to
-simulate the presence of a user's SD card in the device. To do this, you can use
-the android tool to create a new SD card image with a new AVD, or you can use
-the mksdcard utility included in the SDK. </p>
-
-<p>The sections below describe how to create an SD card disk image, how to copy
-files to it, and how to load it in the emulator at startup. </p>
-
-<p>Note that you can only load disk image at emulator startup. Similarly, you
-can not remove a simulated SD card from a running emulator. However, you can
-browse, send files to, and copy/remove files from a simulated SD card either
-with adb or the emulator. </p>
-
-<p>The emulator supports emulated SDHC cards, so you can create an SD card image
-of any size up to 128 gigabytes.</p>
-
-<h3 id="creatinga">Creating an SD card image using the android tool</h3>
-
-<p>The easiest way to create a new SD card is to use the android tool. When
-creating an AVD, you simply specify the <code>-c</code> option, like this: </p>
-
-<pre>android create avd -n <avd_name> -t <targetID> -c <size>[K|M]</pre>
-
-<p>You can also use the <code>-c</code> option to specify a path to an SD card
-image to use in the new AVD. For more information, see <a
-href="{@docRoot}guide/developing/tools/avd.html">Android Virtual Devices</a>.
-</p>
-
-<h3 id="creatingm">Creating an SD card image using mksdcard</h3>
-
-<p>You can use the mksdcard tool, included in the SDK, to create a FAT32 disk
-image that you can load in the emulator at startup. You can access mksdcard in
-the tools/ directory of the SDK and create a disk image like this: </p>
-
-<pre>mksdcard <size> <file></pre>
-
-<p>For example:</p>
-
-<pre>mksdcard 1024M sdcard1.iso</pre>
-
-<p>For more information, see <a href="{@docRoot}guide/developing/tools/othertools.html">Other Tools</a>. </p>
-
-<a name="copying"></a>
-<h3>Copying Files to a Disk Image</h3>
-
-<p>Once you have created the disk image, you can copy files to it prior to
-loading it in the emulator. To copy files, you can mount the image as a loop
-device and then copy the files to it, or you can use a utility such as mtools to
-copy the files directly to the image. The mtools package is available for Linux,
-Mac, and Windows.</p>
-
-<a name="loading"></a>
-<a name="step3" id="step3"></a>
-
-<h3>Loading the Disk Image at Emulator Startup</h3>
-
-<p>By default, the emulator loads the SD card image that is stored with the active
-AVD (see the <code>-avd</code> startup option).</p>
-
-<p>Alternatively, you ca start the emulator with the
-<code>-sdcard</code> flag and specify the name and path of your image (relative
-to the current working directory): </p>
-
-<pre>emulator -sdcard <filepath></pre>

-
-<h2>Troubleshooting Emulator Problems</h2>
-
-<p>The adb utility sees the emulator as an actual physical device. For this reason, you might have to use the -d flag with some common adb commands, such as <code>install</code>. The -d flag lets you specify which of several connected devices to use as the target of a command. If you don't specify -d, the emulator will target the first device in its list. For more information about adb, see <a href="{@docRoot}guide/developing/tools/adb.html">Android Debug Bridge</a>.</p>
-
-<p>For emulators running on Mac OS X, if you see an error "Warning: No DNS servers found" when starting the emulator, check to see whether you have an <code>/etc/resolv.conf</code> file. If not, please run the following line in a command window:</p>
- <pre>ln -s /private/var/run/resolv.conf /etc/resolv.conf</pre>
