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
