Open the starter project in Android Studio. The demo projects for the previous lessons had a single screen. This time, there are multiple independent screens. One for the scopes and another for the dispatchers. You can navigate to one of them from the additional menu screen. There are also tests in the CoroutineTest class. Note it’s in the test directory, instead of in main as is the production code.
Dispatchers
Open the Lesson3DispatchersScreen file. It contains several buttons that start 100 coroutines on various dispatchers. Each coroutine suspends for ten milliseconds and then prints the message to the logcat with the current thread name. In this file, you won’t write any code but observe the logcat messages.

Using Scopes
Open the Lesson3ScopesScreen file. It contains several buttons that interact with the coroutine scopes. The CoroutineScope is created on top of the screen using the rememberCoroutineScope function. It’s the same function as used in the previous lesson. The created scope is bound to the lifetime of the screen composable. It’s canceled when the screen is removed from the composition. You’ll use that scope to launch all the coroutines in this exercise.
