Which one should I pick for a new project?

I can only provide context about which repositories these are and their purposes—the choice depends entirely on your project's needs:

brettwooldridge/hikaricp is a Java JDBC connection pool library. Use this if you need to manage database connections in a Java application. The RepoPilot analysis rates it as GO—Healthy across all four use cases, indicating it's production-ready and reliable. It's lightweight (~165KB) and focused on performance and simplicity [README.md:L11-L12].

harlonwang/avloadingindicatorview is an Android loading indicator UI component library. Use this if you're building an Android app and need animated loading spinners. However, the project is no longer being maintained [README.md:L1-L3], so be aware of the maintenance status before adopting it for a new project.

The decision is about your use case:

• Building a Java backend or service with a database? → HikariCP
• Building an Android app? → AVLoadingIndicatorView (but consider the maintenance status)
• Neither applies? → Neither library is relevant

Can you clarify what type of project you're building?
