BARCELONA, MOBILE WORLD CONGRESS — Chip maker Qualcomm has teamed up with DoubleTwist, the creator of one of the most popular media players for Android, to develop a new media streaming service called MagicPlay.

Vine, a new video sharing service from a small team owned by Twitter, has become a big hit since making its debut on the iPhone back in January, and we Android users want to know when we’re going to get a slice of the action.

Every time you purchase an app from Google Play, Google sends your email address, your suburb, and in many cases your full name to the app’s developer.

Amazon has today announced that its in-app purchasing service, which is already available on the company’s Kindle Fire tablet and other Android devices, is coming to Mac, PC, and web games. This will allow developers to take advantage of Amazon’s service on those platforms to provide their customers with a new way to purchase additional content using their credit card or virtual Amazon currency.

While Amazon isn’t the first company to offer an in-app purchasing system, its service does come with some advantages that developers may not get from its rivals. One of those advantages is that their content will be available via Amazon.com.
