Over the last few years, I have worked on building Android SDKs — mainly for payment flows, app security checks, and internal enterprise tools. These SDKs have been integrated into real client applications, which gave me practical experience with handling integration challenges, debugging issues in diverse environments, and designing APIs that other developers can use easily.Working on SDKs is very different from building apps. You don’t control the environment, you don’t control how integrators write code, and you definitely don’t control how they initialize things.

Building Android SDKs requires different considerations than app development since you don't control the integration environment. Key practices include creating a clean facade layer to expose only essential APIs, avoiding forcing integrators to extend Application classes, performing client-side input validation before network calls, using unique error codes for faster debugging, and implementing structured logging with smart upload mechanisms. These principles help create stable, developer-friendly SDKs that are easy to integrate and maintain.
