Thank you for making B4R. It feels very natural and easy to use after having used the Arduino IDE and alternatives.

Asynchronous MariaDB/MySQL Library

There are a couple of MySQL libraries already available. They all perform network functions on the main thread however which means you are limited to using target API's that are pre Honeycomb level. This is an asynchronous library so it should work with the higher API levels (it has only been tested on Jellybean and KitKat though).

This library uses the MariaDB JDBC driver. It also works with MySQL as MariaDB is a fork of the open source version of MySQL....
