First off all you need to make a copy of your project (you don’t want to be modifying your own current workspace copy) to share.
Remove redundant files
Ensure that you can view hidden files and remove the following directories (where applicable) from your copy:
- /.gradle
- /build
- /captures
- /projectFilesBackup
- /app/build
- /.git (if applicable)
Change project directory
If you won’t be sharing the project inside a directory that has the same name as the directory name of your project in the workspace.
- Rename the project directory
- Rename the .iml file inside the project directory to match the project directory’s name
- In /.idea/modules point to your new .iml file
Remove any local properties
Your project might refer to any local SDK’s. For example in local.properties clear any references to your SDK directory.
If you have removed version control from your project, also remove .idea/vcs.xml
These are just my own findings, and I’m sure this list can be improved so feel free to make any edits!
