The Amplify Android library is AWS' preferred mechanism for interacting with AWS services from an Android device.

The library provides a high-level interface to perform different categories of cloud operations. Each category may be fulfilled by a plugin, which you configure during setup.

The default plugins that we provide are designed to facilitate interaction with Amazon Web Services (AWS). But, the Amplify Framework is designed to be extensible to any other backend or service.

To familiarize yourself with Amplify, checkout our Getting Started Guide.

Categories

Category	AWS Provider	Description
Authentication	Cognito	Building blocks to create auth experiences
Storage	S3	Manages content in public, protected, private storage buckets
DataStore	AppSync	Programming model for shared and distributed data, with simple online/offline synchronization
API (GraphQL)	AppSync	Interact with your GraphQL or AppSync endpoint
API (REST)	API Gateway	Sigv4 signing and AWS auth for API Gateway and other REST endpoints
Analytics	Pinpoint	Collect Analytics data for your app including tracking user sessions
Predictions	Various*	Connect your app with machine learning services like NLP, computer vision, TTS, and more.

* Predictions utilizes a range of Amazon's Machine Learning services, including: Amazon Comprehend, Amazon Polly, Amazon Rekognition, Amazon Textract, and Amazon Translate.

Platform Support

The Amplify Framework supports Android API level 16 (Android 4.1) and above.

Using Amplify from Your App

For step-by-step setup instructions, checkout our Project Setup guide.

Specifying Gradle Dependencies

To begin, include Amplify from your app module's build.gradle dependencies section:

dependencies {
    // Only specify modules that provide functionality your app will use
    implementation 'com.amplifyframework:aws-analytics-pinpoint:1.31.3'
    implementation 'com.amplifyframework:aws-api:1.31.3'
    implementation 'com.amplifyframework:aws-auth-cognito:1.31.3'
    implementation 'com.amplifyframework:aws-datastore:1.31.3'
    implementation 'com.amplifyframework:aws-predictions:1.31.3'
    implementation 'com.amplifyframework:aws-storage-s3:1.31.3'
}

Java 8 Requirement

Amplify Android requires Java 8 features. Please add a compileOptions block inside your app's build.gradle, as below:

android {
    compileOptions {
        coreLibraryDesugaringEnabled true
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

In the same file, add core library desugaring in your dependencies block:

dependencies {
    // Add this line
    coreLibraryDesugaring 'com.android.tools:desugar_jdk_libs:1.0.10'
}

Kotlin & Rx Support

Amplify's default interface renders results through async callbacks. We also provide optional, adapter APIs which better integrate with RxJava and Kotlin:

• Using RxJava with Amplify
• Kotlin Coroutines Support

Authentication

The default plugins for Amplify Android use the Authentication category to provide authentication with AWS services. The default implementation uses Amazon Cognito which allows you to add user sign-up, sign-in, and access control to your mobile apps.

Please see Getting Started with Authentication for full details.
