RhombusLib is an Android library project that decodes magnetic stripe audio data. It is designed for use with the unencrypted SquareUp credit card reading dongle, though it should work with any mechanism to get the raw data from the card as audio.

RhombusLib can decode either track 1 or track 2 data, and can even determine on the fly which one to decode to. It supports swiping in either direction.

A library containing over 1000 material vector icons that can be easily used as Drawable or as a standalone View. Tired of having to search for and generate png resources every time you want to test something? This library puts an end to that burden and makes swapping icons a breeze, check out the usage below and you'll see why.
