     ## Requirements and Support
     
    +### Java Development Kit (JDK)
    +
    +Install [Java Development Kit (JDK) 7](http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html)
    +or later.
    +
    +When installing on Windows you also need to set `JAVA_HOME` Environment Variable
    +according to JDK installation path (for example, `C:\Program Files\Java\jdk1.7.0_75`).
    +
    +### Android SDK
    +
     Cordova for Android requires the Android SDK which could be installed
     on OS X, Linux or Windows operation system. See the Android SDK's
     [System Requirements](http://developer.android.com/sdk/index.html#Requirements).
    -
    -Cordova supports Android 4.0.x (starting with Android API level 14)
    -and higher.  As a general rule, Android versions become unsupported by Cordova as
    +Cordova's latest Android package supports up to Android [API-Level](http://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
23.
    +The supported Android API-Levels for the past few cordova-android releases can
    +be found in this table:
    +
    +cordova-android Version | Supported Android API-Levels
    +------------------------|-----------------------------
    +5.X.X                   | 14 - 23
    +4.1.X                   | 14 - 22
    +4.0.X                   | 10 - 22
    +3.7.X                   | 10 - 21
    +
    +Please note that the versions listed here are for Cordova's Android package,
    +[cordova-android](https://github.com/apache/cordova-android), and not for the
    +Cordova CLI. To determine what version of Cordova's Android package is installed
    +in your Cordova project, run the command `cordova platform ls` in the directory
    +that holds your project.
    +
    +As a general rule, Android versions become unsupported by Cordova as
     they dip below 5% on Google's
     [distribution dashboard](http://developer.android.com/about/dashboards/index.html).
    -Android versions earlier than API level 10, and the 3.x versions (Honeycomb,
    -API levels 11-13) fall significantly below that 5% threshold.
    -
    -## Install Cordova Shell Tools
    -
    -If you want to use Cordova's Android-centered shell tools in
    -conjunction with the SDK, download Cordova from
    -[cordova.apache.org](http://cordova.apache.org). Otherwise ignore this
    -section if you plan to use the cross-platform CLI tool described in
    -[The Command-Line Interface](../../cli/index.html).
     
    -The Cordova download contains separate archives for each platform. Be
    -sure to expand the appropriate archive, `android` in this case, within
    -an empty directory.  The relevant executible utilities are available
    -in the top-level `bin` directory. (Consult the __README__ file if
    -necessary for more detailed directions.)
    +#### Installing the Android SDK
     
    -These shell tools allow you to create, build, and run Android apps.
    -For information on the additional command-line interface that enables
    -plugin features across all platforms, see Using Plugman to Manage
    -Plugins. See Application Plugins for details on how to develop
    -plugins.
    -
    -## Install the Java Development Kit (JDK)
    -
    -Install [Java Development Kit (JDK) 7](http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html)
    -or later. 
    -
    -When installing on Windows you also need to set `JAVA_HOME` Environment Variable
    -according to JDK installation path (for example, C:\Program Files\Java\jdk1.7.0_75).
    -
    -## Install the Android SDK
    -
    -Install the [Android Stand-alone SDK Tools](http://developer.android.com/sdk/installing/index.html?pkg=tools)
or [Android Studio](http://developer.android.com/sdk/installing/index.html?pkg=studio). Procceed
with `Android Studio` if you plan 
    +Install the [Android Stand-alone SDK Tools](http://developer.android.com/sdk/installing/index.html?pkg=tools)
or [Android Studio](http://developer.android.com/sdk/installing/index.html?pkg=studio).
    +Proceed with Android Studio if you plan on
     developing new Cordova for Android plugins or using native tools to
    -run and debug Android platform. Otherwise, `Android Stand-alone SDK Tools`
    -are enough to build and deploy Android application.
    +run and debug the Android platform. Otherwise, the Android Stand-alone SDK Tools
    +are enough to build and deploy Android applications.
     
     Detailed installation instructions are available as part of installation
     links above.
     
    -For Cordova command-line tools to work, or the CLI that is based upon
    -them, you need to include the SDK's `tools` and `platform-tools`
    -directories in your `PATH`.  On a Mac or Linux, you can use a text editor to
    -create or modify the `~/.bash_profile` file, adding a line such as the
    -following, depending on where the SDK installs:
    +#### Update your PATH
    +
    +For Cordova's CLI and command line tools to work correctly, you will need to
    +include the SDK's `tools` and `platform-tools` directories in your `PATH`.
    +
    +##### OS X and Linux
    +
    +On a Mac or Linux, you can use a text editor to create or modify the
    +`~/.bash_profile` file, adding a line such as the following
    +(substitute the paths with your local Android SDK installation's location):
     
             export PATH=${PATH}:/Development/android-sdk/platform-tools:/Development/android-sdk/tools
     
    -This line in `~/.bash_profile` exposes these tools in newly opened terminal
    -windows. If your terminal window is already open in OSX, or to avoid a logout/login
    -on Linux, run this to make them available in the current terminal window:
    +Reload your terminal to see this change reflected or run the following command:
     
             $ source ~/.bash_profile
     
    -To modify the `PATH` environment on Windows:
    +##### Windows
    +
    +On Windows, you must modify the `PATH` environment variable. These steps may
    +vary depending on your installed version of Windows:
     
    -1. Click on the __Start__ menu in the lower-left corner of the desktop,
    -   right-click on __Computer__, then select __Properties__.
    +1. Click on the __Start__ menu in the lower-left corner of the desktop
     
    -1. Select __Advanced System Settings__ in the column on the left.
    +1. In the search bar, search for __Environment Variables__ and select __Edit the system
Environment Variables__ from the options that appear
     
    -1. In the resulting dialog box, press __Environment Variables__.
    +1. In the window that appears, click the __Environment Variables__ button
     
     1. Select the __PATH__ variable and press __Edit__.
     
    -1. Append the following to the `PATH` based on where you installed the
    -   SDK, for example:
    +1. Append the relevant locations to the __PATH__ based on where you installed
    +   the SDK, for example:
     
             ;C:\Development\android-sdk\platform-tools;C:\Development\android-sdk\tools
     
     1. Save the value and close both dialog boxes.
     
    -## Install SDK Packages
    -
    -Open Android SDK Manager (for example, via terminal: `android`) and install:
    -
    -1. Android 5.1.1 (API 22) platform SDK
    -1. Android SDK Build-tools version 19.1.0 or higher
    -1. Android Support Repository (Extras)
    -
    -See [Installing SDK Packages](http://developer.android.com/sdk/installing/adding-packages.html)
    -for more details.
    -
    -## Configure an Emulator
    -
    -Android sdk doesn't provide any default emulator instance by default. You can 
    -create a new one by running `android` on the command line.
    -The press __Tools &rarr; Manage AVDs__ (Android Virtual Devices),
    -then choose any item from __Device Definitions__ in the resulting dialog
    -box:
    -
    -![]({{ site.baseurl }}/static/img/guide/platforms/android/asdk_device.png)
    -
    -Press __Create AVD__, optionally modifying the name, then press __OK__
    -to accept the changes:
    -
    -![]({{ site.baseurl }}/static/img/guide/platforms/android/asdk_newAVD.png)
    -
    -The AVD then appears in the __Android Virtual Devices__ list:
    -
    -![]({{ site.baseurl }}/static/img/guide/platforms/android/asdk_avds.png)
    -
    -To open the emulator as a separate application, select the AVD and
    -press __Start__. It launches much as it would on the device, with
    -additional controls available for hardware buttons:
    -
    -![]({{ site.baseurl }}/static/img/guide/platforms/android/asdk_emulator.png)
    -
    +1. Close and reopen any command prompt windows to see the change reflected
     
    -For a faster experience, you can use the `Virtual Machine Acceleration` to improve 
    -the execution speed.
    -Many modern CPUs provide extensions to execute Virtual Machines more efficiently.
    -Before attempting to use this type of acceleration, you need to determine if your 
    -current development system's CPU, supports one the following virtualization technologies:
    +#### Adding SDK Packages
     
    -* __Intel Virtualization Technology__ (VT-x, vmx) &rarr; [Intel VT-x supported processor
list](http://ark.intel.com/products/virtualizationtechnology)
    -* __AMD Virtualization__ (AMD-V, SVM), only supported for Linux (Since May 2006, all
CPUs AMD include AMD-V, except Sempron).
    +After installing the Android SDK, you must also install the packages for
    +whatever [API level](http://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
    +you wish to target. It is recommended that you install the highest SDK version
    +that your version of cordova-android supports (see above).
     
    -Another way to find out if your Intel processor supports VT-x Technology, it's by executing
the 
    -`Intel Processor Identification Utility`, for `Windows`you can download it from the Intel
[Download Center](https://downloadcenter.intel.com/Detail_Desc.aspx?ProductID=1881&DwnldID=7838),
    -or you can use the [booteable utility](https://downloadcenter.intel.com/Detail_Desc.aspx?ProductID=1881&DwnldID=7840&lang=eng),
which is `OS Independent`.
    +Open Android SDK Manager (for example, run `android` from the terminal) and make
    +sure the following are installed:
     
    -After install and execute the `Intel Processor Identification Utility` over Windows,
you will get the following window, 
    -in order to check if your CPU supports the Virtualization Technologies:
    -
    -![]({{ site.baseurl }}/static/img/guide/platforms/android/intel_pid_util_620px.png)
    -
    -In order to speed up the emulator, you need to download and install one or more `Intel
x86 Atom` System Images, 
    -as well as the `Intel Hardware Accelerated Execution Manager (HAXM)`.
    -
    -Open your Android SDK Manager, and select the `Intel x86 Atom` System Image, for whichever
version that you want to test. Then go to `Extras` 
    -and select `Intel x86 Emulator Accelerator (HAXM)`, and install those packages:
    -
    -![]({{ site.baseurl }}/static/img/guide/platforms/android/asdk_man_intel_image_haxm.png)
    -
    -After download, run the Intel installer, which is available within your
    -Android SDK at `extras/intel/Hardware_Accelerated_Execution_Manager`. 
    -__Note__:`If you have any problems installing the package, you can find more information
and step by step guidance check this` 
    -[Intel Article](http://software.intel.com/en-us/android/articles/speeding-up-the-android-emulator-on-intel-architecture).
    -
    -1. Install one or more `Intel x86 Atom` System Images as well as the
    -   `Intel Hardware Accelerated Execution Manager`, available under
    -   __Extras__.
    -
    -1. Run the Intel installer, which is available within your Android SDK
    -   at `extras/intel/Hardware_Accelerated_Execution_Manager`.
    -
    -1. Create a new AVD with the target set to an Intel image.
    -
    -1. When starting the emulator, ensure there are no error messages
    -   indicating a failure to load HAX modules.
    -
    -## Create a New Project
    -
    -At this point, to create a new project you can choose between the
    -cross-platform CLI tool described in [The Command-Line Interface](../../cli/index.html),
or
    -the set of Android-specific shell tools. From within a source-code
    -directory, here's the CLI approach:
    -
    -        $ cordova create hello com.example.hello HelloWorld
    -        $ cd hello
    -        $ cordova platform add android
    -        $ ccordova prepare              # or "cordova build"
    -
    -Here's the corresponding lower-level shell-tool approach for both Unix
    -and Windows:
    -
    -        $ /path/to/cordova-android/bin/create /path/to/new/hello com.example.hello HelloWorld
    -        C:\path\to\cordova-android\bin\create.bat C:\path\to\new\hello com.example.hello
HelloWorld
    -
    -## Build the Project
    -
    -If you are using the CLI in development, the project directory's
    -top-level `www` directory contains the source files. Run any of
    -these within the project directory to rebuild the app:
    -
    -        $ cordova build                   # build all platforms that were added
    -        $ cordova build android           # build debug for only Android
    -        $ cordova build android --debug   # build debug for only Android
    -        $ cordova build android --release # build release for only Android
    -
    -If you are using the Android-specific shell tools in development,
    -there is a different approach.  Once you generate the project, the
    -default app's source is available in the `assets/www` subdirectory.
    -Subsequent commands are available in its `cordova` subdirectory.
    -
    -The `build` command cleans project files and rebuilds the app. Here is
    -the syntax for both Mac and Windows. The first pair of examples
    -generate debugging information, and the second builds the apps for
    -release:
    -
    -        $ /path/to/project/cordova/build --debug
    -        C:\path\to\project\cordova\build.bat --debug
    -        
    -        $ /path/to/project/cordova/build --release
    -        C:\path\to\project\cordova\build.bat --release
    -
    -## Deploy the app
    -
    -You can use the `cordova` CLI utility to deploy the
    -application to the emulator or the device from the command line:
    -
    -        $ cordova emulate android       #to deploy the app on a default android emulator
    -        $ cordova run android --device  #to deploy the app on a connected device
    -
    -Otherwise, use the alternate shell interface:
    -
    -        $ /path/to/project/cordova/run --emulator
    -        $ /path/to/project/cordova/run --device
    -
    -You can use __cordova run android --list__ to see all available targets and 
    -__cordova run android --target=target_name__ to run application on a specific 
    -device or emulator (for example,  `cordova run android --target="Nexus4_emulator"`).
    -
    -You can also use __cordova run --help__ to see additional build and run
    -options.
    -
    -This pushes the app to the home screen and launches it:
    +1. Android Platform SDK for your targeted version of Android
    +1. Android SDK Build-tools version 19.1.0 or higher
    +1. Android Support Repository (found under "Extras")
     
    -![]({{ site.baseurl }}/static/img/guide/platforms/android/emulator2x.png)
    +See Android's documentation on [Installing SDK Packages](http://developer.android.com/sdk/installing/adding-packages.html)
    +for more details.
     
    -When you `run` the app, you also `build` it. You can append additional
    -`--debug`, `--release`, and `--nobuild` flags to control how it is
    -built, or even whether a rebuild is necessary:
    +## Setting up an Emulator
     
    -        $ /path/to/project/cordova/run --emulator --nobuild
    +If you wish to run your Cordova app on an Android emulator, you will first need
    +to create an Android Virtual Device (AVD). See the Android documentation for
    +[managing AVDs](http://developer.android.com/tools/devices/managing-avds.html)
    +and the [instructions](http://developer.android.com/tools/devices/emulator.html)
    +for configuring the emulator and setting up hardware acceleration.
     
    -## Other Commands
    +Once your AVD is configured correctly, you should be able to see it by running
    +the command:
     
    -The following generates a detailed log of the app as it runs:
    +    $ cordova run --list

    Doesn't hurt, I guess.
