Spanish lottery android application (Google Play link).
This is the first application we published back in 2009, for the version 1.5 of Android. YAY!
It provides up-to-date information about the following lotteries: Euromillón, Bonoloto, Once, 7/39 de la Once, Cuponazo de la Once, Quiniela, Primitiva, Gordo Primitiva, Lotería Nacional, Quinigol, Lototurf, Quintuple plus, Loto Cataluña 6/49.
The first version of Lottodroid used an old-style JSON notreallyRESTful API, fetching daily all the lottery information from the official API of the Spanish government (Hacienda y administraciones públicas) and saved it in a MySQL database. The backend was done in PHP and used a custom MVC mini-framework developed in-house. It's still here for historical reasons, mostly.
Later, in 2011, we partnered with Lotoluck to get the lottery results from them instead.
The first version of 2009 was developed by espinchi and ompemi, and in 2011 hudomjo did a refactoring to switch to Lotoluck as our lottery result provider.
