Titanium SDK 3.1.0 : TypeError: argument of type 'NoneType' is not iterable
When I moved our Titanium Alloy project from 3.1.1 to 3.1.0. I found "TypeError: argument of type 'NoneType' is not iterable" error. And build failed.   After searching on internet found below solution.   For Mac:    Open terminal  cd  /Applications/android-sdk/platform-tools  ln -s /Applications/Android-sdk/build-tools/17.0.0/aapt aapt  ln -s /Applications/Android-sdk/build-tools/17.0.0/dx dx            source: https://developer.appcelerator.com/question/152497/titanium-sdk-310-error-typeerror-argument-of-type-nonetype-is-not-iterable-on-building-android-app   Regards,  Jakir
