Download Requirements and Update the Android SDK
================================================

* The Android SDK Tools

	https://developer.android.com/studio/index.html

* The Android NDK (Tested using android-ndk-r10c)

* Apache Ant v1.8 or later 

		http://ant.apache.org/bindownload.cgi

* Java SE Development Kit (JDK) v6 or later

		http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html

* Update the Android SDK to get the API and tools packages required for development

	Tested using Android 4.4.2 (API 19)

* In Windows - Define the next Environment Variables based on your system.

(1) JAVA_HOME

.. code-block:: ring
	
	For Example : C:\Program Files (x86)\Java\jdk1.8.0_05

Building the project
====================

Move to the ring/android/ringlibsdl/project folder 

We can build using the next command (We need to do this for one time only).

.. code-block:: none

	ndk-build

Then we can create the package (*.apk) using the next command.

.. code-block:: none

	ant debug
