Short answer
A software development kit (SDK) is a package of code, libraries, and tools that developers embed in an app to add specific functions. Common examples handle analytics, attribution, advertising, payments, or push messaging. SDKs save development time, but each one adds app size, potential privacy obligations, and dependence on a third party.
