Google is putting up $10-million in prizes for the best applications written for its Android mobile phone operating system.
The search giant announced last week that it was developing Android as an open platform for third party developers to create new software for mobile phones.
Now it has launched the new platform's software development tool kit and also announced the Android Developer Challenge.
The top 50 entries will be selected from programs received between 2 January and 3 March 2008.
Each of them will get a cash proze of $25 000.00, while 10 of them will receive $100 000.00 and the top 10 will get $275 000.00.
So far, four mobile phone vendors have said they will use Android on some of their phones. They are Motorola, Samsung, HTC and LG.
