I went into my xcode project folder directory in terminal, and typed apportable load
in there, and it compiled my project, but I'm not sure where the ADK is for me to upload to Google Play... Does apportable create uploadable ADK's or, no? I thought it did.
All Apportable build artifacts, including apk files are in the ~/.apportable/SDK/Build directory.
Full details about making release builds are in the Apportable docs here.
