square/leakcanary ? reverse-engineered prompt

Build me an Android library that helps developers find memory leaks in their app. I want it to watch app objects, detect when something is being kept in memory too long, and give a clear report that shows what is leaking and what is holding on to it.

Please make it feel polished and easy to use in a real Android project, with a simple setup flow and a small sample app or example integration so I can see how it works. If you need to check current Android or Kotlin docs online while implementing, go ahead.

I also want the project organized so the core leak detection logic is separate from any UI or app facing pieces, and the code should be ready for a production Android library. Include useful tests and clear documentation so someone can understand how to plug it into their app and read the leak results.
