Which one should I pick for a new project?

I can only give you limited guidance here because both repositories have significant maintenance concerns that should weigh heavily on your decision:

chrisbanes/android-pulltorefresh:

• Status: DEPRECATED and unmaintained (last commit 9 years ago per RepoPilot verdict)
• Verdict: "WAIT — Stale"
• The README explicitly states: "PLEASE NOTE, THIS PROJECT IS NO LONGER BEING MAINTAINED"
• Not suitable for new projects — this library is obsolete.

greenrobot/eventbus:

• More active than android-pulltorefresh, but the repository data shown doesn't include RepoPilot signals about its staleness or maintenance status
• Appears to have a defined contribution process [CONTRIBUTING.md]
• However, I cannot assess its current maintenance status from the data provided

Recommendation:

• Do not use android-pulltorefresh for new projects.
• For eventbus, you'd need to verify its current maintenance status and whether it fits your use case. If you need pull-to-refresh functionality for Android, look for actively maintained modern alternatives (like Google's SwipeRefreshLayout or newer third-party libraries).

If you have a specific use case in mind (pull-to-refresh vs. event dispatching), I can provide more targeted guidance about what each library does.

• What functionality does your new project need?
• Is eventbus still actively maintained?
• Are there modern Android architecture alternatives available?
