Android developer portal with tools, libraries, and apps

Under the Hood is a flexible and powerful Android debug view library. It uses a modular template system that can be easily extended to your needs, although coming with many useful elements built-in.

There is a lot of "default" debug data that can be easily embedded (e.g. current runtime-permission status, app version and device info). There are 2 basic themes (dark and light) which can be customized to your needs.

OffsetAnimator lets animate objects basing on touchevents, so users can be engaged into animation process. It simply integrates with ViewPager.

A wonderful library to display 2D fancy carousels for Android.
