Exception handling is always a cumbersome but unavoidable part of dealing with disk cache on Android. Complex error handling not only makes your code hard to understand, but also prone to developer errors. IgDiskCache is a fault-tolerant Android disk cache library that helps simplify the error handling logic and makes your file caching code cleaner and much easier to maintain.
One of the fastest caching libraries for Java. Lots of features for advanced integrations of external systems: (Variable entry) expiry, exception handling with configurable resilience, loaders/writers, events, statistics. Configuration can also be done via XML (optional feature).
