Noodle is a very simple object storage and persistence library for Android.
No schema, no relations, no consistency rules, no thread-contained objects. You can use it as a key-value storage or collections - which are similar to tables, but not really.
PageStateLayout could let you show Loading / Empty / Error / Succeed / Requesting state in Activity
, Fragment
, ViewGroup
as you want.
Kickstarter MVP framework for android projects.
