Amazon has launched SDKs for Android and iOS, aimed at making it easier for software developers to call an AWS web service API directly from a mobile application.
With the mobile SDKs, developers can write software that uses AWS infrastructure in their mobile applications, including:
Store and retrieve data using Amazon Simple Storage Service (Amazon S3).
Add a highly available, scalable, and flexible non-relational data store using Amazon SimpleDB with little or no administrative burden.
Integrate reliable, highly scalable mobile-to-mobile communication into applications using Amazon Simple Queue Service (Amazon SQS), and Amazon Simple Notifications Service (Amazon SNS).
