Mobile SDK Design

A series about designing mobile SDKs that are easy to adopt, clear to integrate, and safe under production constraints.

Reading order

1. 01Designing a Mobile SDK That Developers Actually Want to UseA developer-friendly SDK starts with one clear entry point, sensible defaults, and architecture that matches the caller's mental model.
2. 02The Public API Surface Is the ProductThe public API surface is the product. Every name, type, and callback you expose becomes part of how developers think about your SDK.
3. 03Initialization, State, and Thread Safety in Mobile SDKsThe first five minutes of integration determine whether developers trust your SDK. Design initialization, state transitions, and thread contracts deliberately.
4. 04Developers Do Not Mind Errors. They Mind Unclear Errors.Error handling is part of your public API. Design it for the developer trying to diagnose a problem at 2am, not for the team that wrote the SDK.
5. 05Shipping the SDK Is Where Trust StartsDistribution, versioning, binary size, and startup cost are part of SDK design. Host-app tech leads evaluate all of it, not just the API.
6. 06Secure Defaults for Mobile SDKsSecure defaults mean safe behavior is the path of least resistance. Design the SDK so doing the right thing is easier than doing the wrong thing.
7. 07Same Concepts, Native ExperienceCross-platform consistency means shared concepts, not identical syntax. The goal is that a developer who has integrated the Android SDK feels oriented when opening the iOS documentation.
