Facebook authentication in Windows Phone application by somnathbanik
Authentication gives your app the ability to know the identity of a Facebook user, and to read and write data via Facebook’s APIs. The Facebook Platform uses OAuth 2.0 for authentication and authorization. A successful authentication flow results in your application obtaining a user access token which can be used to make requests to Facebook’s APIs.
This week’s featured article is about using OAuth2.0 for Facebook – for a Windows Phone 7 developer. The article walks you through the various steps involved in implementing including: adding controls on application page, launching Facebook login page, get the code and access token and finally loading the user’s profile.
The article also includes a working buildable code example. If you are integrating facebook with your WP7 application make sure you try out the example in the article. Let us know how it goes
Harri Myllynen, CEO at Offscreen Technologies, talks about the success this Finnish developer has found for its mobile games, utilities, media, entertainment, and internet apps through Nokia Store.
The team behind Offscreen started creating apps in 2003 and formed the company in 2005 as the interest in smartphones grew. They now employ 16 people in Helsinki and Shanghai.
While the range of apps the company has created is wide, they have learnt that simple apps can be the most successful — as exemplified by their Bright Light app, which turns on a phone’s flash LED to act as a torch. ‘It’s still the most downloaded application of ours. It took about six hours to develop including the graphic design, yet it’s so popular,’ says Harri.
In addition, by making their apps available for free, according to Harri, they see an immediate 100-fold increase in downloads. Offscreen then uses in-app advertising or in-app purchasing to monetise these apps — with half the company’s application revenue coming from in-app advertising.
“We are very pleased to be working with Nokia, with the reach that Nokia Store offers to almost 200 countries,” says Harri. ‘And the whole team felt really proud and happy when we reached 100 million downloads.’
MinesFinderS40 is a Series40 Web Apps game by lorion84. It’s a clone of Windows based Minesweeper game. The main screen consists of a grid. Some cells of this grid have mines planted in them. The goal of the game is to discover all the mines in the shortest amount of time without clicking on the hidden mines. At the end the grid should be cleared with only the mined cells remaining.
The game has been developed for Asha Touch Series40 devices which reach the next billion consumers. You can run the application by visiting http://eve-c.org/minesfinder on Series40 Nokia Browser or check out this link http://store.ovi.com/content/299489 to download it from Nokia Store.
