Package com.codename1.backend.aws

package com.codename1.backend.aws

Amazon Web Services from a backend: request signing, credentials, and S3.

Aws implements Signature Version 4, which every AWS service shares. Credentials finds the credentials a deployment provides, in the order AWS documents them: the environment, the container credential endpoint, then the instance metadata service. S3 reads and writes objects on Amazon S3 and on the services that speak its API.

Server code: none of this is available in the app.
