Optimizely Android SDK

Overview

This repository houses the Android SDK for use with Optimizely Full Stack and Optimizely Rollouts. The Android SDK depends on the Optimizely Java SDK.

Optimizely Full Stack is A/B testing and feature flag management for product development teams. Experiment in any application. Make every feature on your roadmap an opportunity to learn. Learn more at https://www.optimizely.com/platform/full-stack/, or see the documentation.

Optimizely Rollouts is free feature flags for development teams. Easily roll out and roll back features in any application without code deploys. Mitigate risk for every feature on your roadmap. Learn more at https://www.optimizely.com/rollouts/, or see the documentation.

Getting Started

Using the SDK

See the Mobile developer documentation to learn how to set up an Optimizely X project and start using the SDK.

Requirements

• Android API 14 or higher

Installing the SDK

To add the android-sdk and all modules to your project, include the following in your app's build.gradle:

---

NOTE

Bintray/JCenter will be shut down. The publish repository has been migrated to MavenCentral for the SDK version 3.10.1 or later. Older versions will be available in JCenter until February 1st, 2022.

---

repositories {
	mavenCentral()
  	jcenter()
}

dependencies {
	implementation 'com.optimizely.ab:android-sdk:3.13.0'
}

Samples

A sample code for SDK initialization and experiments:

OptimizelyManager optimizelyManager = OptimizelyManager.builder()
            .withSDKKey("my_sdk_key")
            .withDatafileDownloadInterval(TimeUnit.MINUTES.toSeconds(15))
            .build(getApplicationContext());
            
optimizelyManager.initialize(this, null, (OptimizelyClient optimizely) -> {
	OptimizelyClient optimizely = optimizelyManager.getOptimizely();
	
	Variation variation = optimizely.activate("background_experiment", userId);
	
	optimizely.track("sample_conversion", userId);
});

Architecture

This project includes 5 library modules and a test app.

1. Android SDK

• Users who want all modules should declare a dependency on this module.
• This is the outer module that depends on all other modules.
• This builds Optimizely objects and provides all public APIs.

2. Datafile Handler

• This handles downloading the datafile from the Optimizely server.

3. Event Handler

• This handles dispatching events to the Optimizely server.
• This uses a Service so events can be sent without the app being re-opened.
• Events remain persistent until dispatching completed successfully.

4. User Profile

• Persistent bucketing
• Once a user is bucketed in a variation, the user will remain in that variation.

5. Shared

• Common utils for all modules

6. Test App

• A simple app showing how to use the Optimizely Android SDK

Development

Command Line

1. Clone the repo

• git clone git@github.com:optimizely/android-sdk.git

2. Create, or use an existing, Optimizely Android project
3. Build the project (from the project root)

• ./gradlew assemble

4. Run tests for all modules

• ./gradlew testAllModules
• A device or emulator must be connected.

5. Install the test app onto all connected devices and emulators

• ./gradlew test-app:installDebug
• The test app depends on all of the other project modules.
• The modules are built from source.

6. Discover more gradle tasks

• ./gradlew tasks
• To see the task of an individual module: ./gradlew user-profile:tasks

Android Studio

Android Studio is an IDE that wraps gradle. Everything you can do in Android Studio can be done from the command line tools.

You can import this project into Android Studio by opening Android Studio and selecting Import Project from the first dialog or from the File menu. Simply select the project's root build.gradle file and Android Studio will do the rest.

Tests can be run by right clicking the file in the project pane or by clicking the method name in source and selecting run. You will be prompted to create an AVD or connect a device if one isn't connected.
