10. CHAPTER
FIFTYSIX
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.
56.1 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.
1. JAVA_HOME
For Example : C:Program Files (x86)Javajdk1.8.0_05
2. ANDROID_HOME
For Example : B:mahmoudToolsJava-Androidadt-bundle-windows-x86-20140702sdk
56.2 Project Folder
Open the project folder : ring/android/ringlibsdl/project
