This document discusses various open source Android libraries and tools that can be used to build Android applications more efficiently. It summarizes RoboGuice for dependency injection, ActionBarSherlock for action bar support, libraries like HTTP Request and GSON, and tools like ViewPagerIndicator, Robotium for testing, the Android Maven plugin, and fragments. It encourages leveraging these libraries and tools to build more with less code through reuse and integration of existing components.
