Question

I have no idea, which files should be versioned for a new android project created in eclipse. Could anyone tell me, what I should add??

Answer 1

Pretty much everything you need to build your project, including:

• .project and .classpath (yes, you should definitively add them, provided the .classpath doesn’t include any absolute path: any other Eclipse users who would access your versioned project will thank you for that)
• .settings content (for project Eclipse specific settings)
• other build-related files (like a pom.xml, if you have one)
• launcher configuration (again, if you have some)

Nothing that is generated (like the directory ‘gen‘, or ‘bin‘) should be added to source control
Workspace Eclipse metadata shouldn’t be versioned either.

As I said in “Do you keep your project files under version control?“, the goal is to ease and quicken the project setup process when checked-out in a workspace:

“Load it up, set it up, go.”
