The net-handler-android package enables the asynchronous processing of requests in Android applications. Any kind of request (HTTP data, RSS feeds, DB queries, file-system access, etc.) can be made, and any number of requests can be made at the same time. The requests are queued in a thread pool, and an application-supplied callback interface is used to notify the application when data is ready for use.

The net-handler-android package was written specifically for Android application, but nothing in the library prevents it from being used in non-Android applications.
