Building Games For Android

In this chapter we will learn about Building RingLibSDL Games for Mobile.

So we can create packages (*.apk) for the applications that are developed using Ring Game Engine for 2D Games.

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)

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

JAVA_HOME

For Example : C:\Program Files (x86)\Java\jdk1.8.0_05

ANDROID_HOME

For Example : B:\mahmoud\Tools\Java-Android\adt-bundle-windows-x86-20140702\sdk

Project Folder

Open the project folder : ring/extensions/android/ringlibsdl/project

You can add the source code (*.ring) and Images/Sound Files to the assets folder.

You will find the Flappy Bird 3000 Game ready for building.

The execution starts from the start.ring file

load "game2.ring"

Building the project

Move to the ring/extensions/android/ringlibsdl/project folder

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

ndk-build

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

ant debug

We can write a batch file for building the project (file: build.bat)

rem You will need to modify this batch file based on your environment

set JAVA_HOME=C:\Program Files (x86)\Java\jdk1.8.0_05
set ANDROID_HOME=B:\mahmoud\Tools\JavaAndroid\adt-bundle-windows-x86-20140702\sdk
set NDK_ROOT=B:\mahmoud\Tools\JavaAndroid\android-ndk-r10c

set path=%path%;B:\mahmoud\Tools\JavaAndroid\android-ndk-r10c
set path=%path%;B:\mahmoud\Tools\JavaAndroid\apache-ant-1.9.4\bin

ndk-build
