Person::i still needs to be defined (outside the class body): int Person ::i;

Only those statics that aren't assigned a value inside the body need to be defined outside. And only non-volatile constant integrals can have such an in-body assignment.

Putting something on the global namespace, or putting them in a lib will not reduce your overall memory usage. Especially if you are going to require it everywhere there is no point. The benefit of a lib is when you only require it sometimes it is only loaded when actually needed.

So in your case there is no need to refactor it purely for memory reasons.

However it is recommended to put functionality in lib folders for organisation purposes.

There was a similar duplicate entry issue on regular android modules compiled with certain 6.x sdks, but I haven't run across something like this for compiled CommonJS modules. Give this a try:

1. In your app project, navigate to modules/android/modulename/version
2. Make a backup of modulename.jar in case the following breaks something
3. Do unzip -l modulename.jar. Look for the metadata.json file.
4. If it is there, do a zip -d modulename.jar path/to/metadata.json

Then try rebuilding your project.
