In our mocha tests suite we used Ti.Filesystem.applicationDirectory to access files from the app Resources directory (xml files, js files, etc). Apparently this property is undefined/null on Android and we should instead be using Ti.Filesystem.resourcesDirectory.
However, if we do something like:
That code will hard-crash Android with an NPE. Considering that is valid code on iOS, and that we don't complain/spit out an error - but actually crash the app, I'd think we might want to safeguard a little better here. If we see a null in the path arguments, we should probably spit out an error and return null.
