The Humble Bundle now supports Android as a platform. The game bundle which you choose yourself how much you pay for well-known indie games was as yet only available for Windows, Mac and Linux. Unique to the Humble Bundle is that you can choose where your money goes, or the developers or to a charity. Games that are offered include osmosis, Edge, Anomaly: Warzone Earth and World of Goo .
Now the chosen charities are Child's Play Charity and the Electronic Frontier Foundation. The latter organization puts itself in the rooten of Android devices, so it's money well spent. If gaming over Humble Bundle you can buy them through updating the website. Some games (Edge and osmosis) have been adjusted so that you receive a notification when an update is ready.
An Android app for Humble Bundle is in the works. This lets you track how much money you've spent and what exactly you have purchased.
