Deep diving into the Kotlin Coroutines API
summary
Covers the Kotlin Coroutines API and its internals with concrete examples: shows how launch/async builders create coroutines, how a Job and Dispatchers entry in CoroutineContext controls lifecycle and threading, and how async/await yields parallel Deferred results. Demonstrates cancellation that stops in-progress work rather than blocking threads, decompiled suspend functions become a continuation state machine (the async decompile explodes into a huge staircase), and gives practical rules: avoid GlobalScope, tie scopes to presenters/activities, prefer async for results.
