greenrobot-common provides general purpose utilities for Android and Java projects. Having its root in the early days of Android development, the library is minimalistic, tiny in size (jar < 100k), and focuses on efficiency and performance.
The Utility classes cover stream-based IO, files, strings, and date/time. There are also efficient hash map and hash set implementation for primitive long keys.
