Amazon S3 concepts

• Buckets: is a container for objects stored in Amazon S3. Every object is contained in a bucket.

• Objects:Objects are the fundamental entities stored in Amazon S3. Objects consist of object data and metadata.

• Keys:A key is the unique identifier for an object within a bucket. Every object in a bucket has exactly one key.

• Regions:You can choose the geographical AWS Region where Amazon S3 will store the buckets that you create.

The REST interface

• Using REST, you use standard HTTP requests to create, fetch, and delete buckets and objects.
• You can use any toolkit that supports HTTP to use the REST API.
• In some areas, we have added functionality to HTTP. In these cases, we have done our best to add the new functionality in a way that matched the style of standard HTTP usage.

Install Amplify dependencies

• Expand Gradle Scripts, open build.gradle (Module: app).

• Add these libraries into the dependencies block:

dependencies {
    implementation 'com.amplifyframework:aws-storage-s3:1.17.4'
    implementation 'com.amplifyframework:aws-auth-cognito:1.17.4'
