Conclusion

That’s it! You’ve just implemented your first coroutine. You’ve learned:

• How to start a coroutine in an Android application.
• The difference between the runBlocking and the launch coroutine builders and between blocking and suspending code execution.
• How to cancel coroutines. Remember that a coroutine cancellation consists of throwing an exception. You must not catch the exception without re-throwing it later, because the coroutine in question could keep running indefinitely.

In the next lesson, you’ll learn about coroutine scopes and dispatchers.
