hannels are one of the most underrated features in Kotlin Coroutines. They solve problems that Flow alone cannot — especially when you're dealing with concurrency, event streams, or multi-producer pipelines in Android apps.
I’ve created a complete Q&A guide that covers:
What exactly Channels are
How they work under the hood
Channel vs Flow vs SharedFlow vs callbackFlow
Real Android use cases (MVI event streams, background tasks, producer–consumer patterns)
Advanced interview questions with detailed answers
If you want to strengthen your Coroutines knowledge or prepare for Android interviews, this guide is made for you.
