I think C2 should follow mrchay path on getting C2 to create the APK. mrchay managed a 20mb tool that will compile the project to APK. Works similar in concept to how NodeWebkit does it.
All that would be required for compile to Android rather than Crosswalk. Would be that the developer has Java Runtime Environment installed.
mrchay easy APK builder
You can't use this practically right now as there are problems. There is no manifest modifcation, wrong icon is used, and C2 audio is not working(crashed out). But it's a 2 step process.
1. Copy all files into the HTML5 folder.
2. Double click go.bat
Boom you have a signed APK
If C2 offered this where you can have manifest options, use the current icons and compile. I think it could then officially 100% no doubt offer Android compile. At this time I do however agree that the compile should be called Crosswalk.
