Imagine your Android “cookbook” application tells you to buy eggs, ginger, and cardamom, your “birthday reminder” application suggests you to buy a blue tulip (for a friend who loves the color blue), and your computer at home notifies your mobile phone that the color cartridge of your printer is almost empty. Would you like to receive three notifications by three different programs next time you are close to a supermarket? Or rather have them all store that information in your central shopping list? (by the way, your internet auction application that watches the central shopping list has already found an interesting offer for that blue tulip…)

Imagine you have to specify for a handful of programs (the favorite “ring-tone selector” application, your “answering machine”, your “smart to-do list”, your “calendar”, your “work time log”, …) where your “home”, your “office”, “gym”, “music school”, etc. is located by specifying the latitude and longitude or the corresponding street address for each of these applications. Would you not rather have a central place for your favorite locations that all applications can easily share?

(Many more ideas can be found on our list of ideas)

Keep your one great idea a secret that could make you win the Android Developer Challenge, but share those obvious and common ideas that you encounter while implementing and that you think could be used in many other applications as well. We will develop the most-required components together (e.g. a central shopping list), so you can concentrate on implementing your core idea (e.g. the weight-watching cookbook) while having interoperability with many other great OpenIntents applications built in right from the start.

Join this project if you have great ideas to share or if you are a good developer and look for a low-risk project.
