The reason you see that error is because the library aws-java-sdk-dynamodb isn't exported to the APK. If you use eclipse, please check your project properties -> Java build path -> Order and export.

The DynamoDB document API is offered by AWS Java SDK, but is unavailable in AWS SDK for Android. If you plan to use an SDK on Android, please consider AWS SDK for Android which is fully tested on Android and is optimized for Android in terms of library size, method count number, and performance. See http://aws.amazon.com/mobile/sdk/ for more information.
