Based off of Scratch 2.0 by MIT: http://scratch.mit.edu
To build Scratch 2.0 for mobile you will need Ant, the Flex SDK version 4.10+, and playerglobal.swc files for Flash Player versions 10.2 and 11.4 added to the Flex SDK.
After downloading playerglobal11_4.swc and playerglobal10_2.swc, move them to <path to flex>/frameworks/libs/player/<version>/playerglobal.swc. E.g., playerglobal11_4.swc should be located at <path to flex>/frameworks/libs/player/11.4/playerglobal.swc.
Create a local.properties file to set the required options. Your local.properties file may look something like this:
FLEX_HOME=/Users/elfin8er/Downloads/flexsdk
SCRATCH_HOME=/Users/elfin8er/Documents/Programming/ScratchMobile/scratch-flash
android.certificate.password=PASSWORD
ios.certificate.password=1234
bin.ext=.bat
certificates.path=${SCRATCH_HOME}/certificates
ios.provision.path=${certificates.path}/Scratch_iOS.mobileprovision
ios.certificate.path=${certificates.path}/Scratch_iOS.p12
android.certificate.path=${certificates.path}/Scratch_android.p12
I have included iOS and Android certificates, but if you'd like to use your own, you can define their locations above. You can create an Android certificate with the following command:
keytool -genkey -v -keystore myname.key.p12 -alias alias_name -keyalg RSA -storetype pkcs12 -keysize 2048 -validity 10000
Now you can run Ant ('ant' from the commandline) to build a 11.6 SWF, 10.2 SWF, APK, and iPA.
If the source is building but the resulting .swf is producing runtime errors, your first course of action should be to download version 4.11 of the Flex SDK and try targeting that. The Apache foundation maintains an installer that lets you select a variety of versions.
