The Adobe Experience Platform SDK is required to power Adobe's Experience Cloud solutions and services in your mobile apps. The SDK is composed of the Mobile Core and a series of Adobe Experience Cloud solutions or third-party vendor Extensions that depend on the Mobile Core. Each Extension registers with the Mobile Core to provide features specific to the solution or service it represents.
To start implementing the SDK, you'll need to first create a mobile property in Adobe Experience Platform Launch. You'll setup configuration required by the Mobile Core and any Extensions you add, and then publish the configuration into an Environment. When you implement the SDK in your app, you'll reference the Environment to get going.
