Third party modules build for 6.0.0.GA are not incompatible with 7.0.0.GA. When rebuilding for 7.0.0.GA I am getting bellow error.
/Users/dipannita/Documents/Projects/Modules_For_7/Ti-Android-SMSVerification/android/build.xml:55: Cannot find /Users/dipannita/Library/Application Support/Titanium/mobilesdk/osx/7.0.0.GA/module/android/build.xml imported from /Users/dipannita/Documents/Projects/Modules_For_7/Ti-Android-SMSVerification/android/build.xml
How to rebuild modules for 7.0.0.GA using ant?
Have a look at this documentation on how to build modules: http://docs.appcelerator.com/platform/latest/#!/guide/Android_Module_Upgrade_Guide
And use appc ti build -p android -b instead of the old ant
