Example 2 with S3Signer

use of com.amazonaws.services.s3.internal.S3Signer in project aws-sdk-android by aws-amplify.

the class AmazonS3Client method createSigner.

/**

 * and the current S3 client configuration into account.
 *
 * Signer = get a Signer based on the bucket endpoint // InternalConfig in CoreRuntime makes this decision
 * [If the region is not specified, uses SigV2 signer,
 * Else If the region is specified, and If the region only supports SigV4, then uses SigV4]
 * If Signer is not Overriden {
 *    If Signer is a V4 Signer and Region is null
 *       Get the region from AmazonS3Client or BucketRegionCache
 *       If available
 *           Use SigV4
 *       Else If PresignedUrl
 *           Use SigV2
 *   If Signer Region is overriden
 *       Use SigV4
 *   If BucketRegionCache has a region
 *       Use SigV4

 * If Signer is SigV2 signer
