Amplify for Android
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 |
Geo | Location | Add maps to your app with APIs and map UI components |
Predictions | Various* | Connect your app with machine learning services like NLP, computer vision, TTS, and more. |
Push Notifications | Pinpoint | Segment users, trigger push notifications, and record metrics |
* Predictions utilizes a range of Amazon's Machine Learning services, including: Amazon Comprehend, Amazon Polly, Amazon Rekognition, Amazon Textract, and Amazon Translate.
All services and features not listed above are supported via the Kotlin SDK or if supported by a category can be accessed via the Escape Hatch like below:
Kotlin
val s3StoragePlugin = Amplify.Storage.getPlugin("awsS3StoragePlugin")
val s3Client = s3StoragePlugin.escapeHatch as S3Client
Java
AWSS3StoragePlugin plugin = (AWSS3StoragePlugin) Amplify.Storage.getPlugin("awsS3StoragePlugin");
S3Client s3Client = plugin.getEscapeHatch();
Platform Support
The Amplify Framework supports Android API level 24 (Android 7.0) 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:2.8.5'
implementation 'com.amplifyframework:aws-api:2.8.5'
implementation 'com.amplifyframework:aws-auth-cognito:2.8.5'
implementation 'com.amplifyframework:aws-datastore:2.8.5'
implementation 'com.amplifyframework:aws-predictions:2.8.5'
implementation 'com.amplifyframework:aws-storage-s3:2.8.5'
implementation 'com.amplifyframework:aws-geo-location:2.8.5'
implementation 'com.amplifyframework:aws-push-notifications-pinpoint:2.8.5'
}
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:
