Running S3TransferUtility Sample

This sample demonstrates how to use the high-level class TransferUtility to perform download and upload tasks and manage the tasks. You can also follow the tutorial for a step-by-step guide in understanding the S3TransferUtilitySample.

Create a identity pool
- Go to Amazon Cognito Console and choose Manage Identity Pools.
- Click Create new Identity pool button on the top left of the console.
- Give a name for the Identity pool and check Enable access to unauthenticated identities under the Unauthenticated Identities section, click Create pool button on the bottom right.
- To enable Cognito Identities to access your resources, expand the View Details section to see the two roles that are to be created. Make a note of the unauth role whose name is of the form Cognito_<IdentityPoolName>Unauth_Role. Now click Allow button in the bottom right of the console.
- Under Get AWSCredentials section, in the code snippet to create CognitoCachingCredentialsProvider , find the Identity pool ID and the AWS region and make note of them. You will need to add to the sample application later.
Set up permissions
- Go to Amazon IAM Console and select "Roles".
- Select the unauth role you just created in step 1, which is of the form Cognito_<IdentityPoolName>Unauth_Role.
- Select Attach Policy, then find AmazonS3FullAccess and attach it it to the role.
- Note: This will grant users in the identity pool full access to all buckets and operations in S3. In a real app, you should restrict users to only have access to the resources they need.
Create a bucket
- Go to Amazon S3 Console and click Create bucket.
- Enter a name for the bucket that is DNS-compliant. For restrictions on bucket naming refer Bucket Restrictions and Limitations.
- Choose the region that you want the bucket to be created.
- Click Create. Note the name and the region of the bucket that was created.
Import the sample project
- Import the sample as Android project into your IDE of choice.
- Open awsconfiguration.json in /res/raw directory.
- Update PoolId with the ID of the Cognito Identity Pool created in Step-1.
- Update Region with the region of the Cognito Identity Pool created from Step-1. For example, us-east-1. The Region column in Amazon Cognito Identity Regions represents the region string.
```
"CredentialsProvider": {
  "CognitoIdentity": {
    "Default": {
      "PoolId": "REPLACE_ME",
      "Region": "REPLACE_ME"
    }
  }
},
```
- Update Bucket with the name of the S3 Bucket created in Step-3.
- Update Region with the region of the S3 Bucket created from Step-3. For example, us-east-1. The Regioncolumn in Amazon S3 Regions represents the region string.
```
"S3TransferUtility": {
  "Default": {
    "Bucket": "REPLACE_ME",
    "Region": "REPLACE_ME"
  }
}
```
Import the AWS SDK for Android
- This application used Gradle to resolve the dependencies required by the app and fetches from maven. This app depends on aws-android-sdk-s3 in build.gradle.
