For an Android project, you would want to add a dependency on org.jetbrains.kotlinx:kotlinx-coroutines-android. This has transitive dependencies to pull in the core coroutines code, plus it has Android-specific elements.

Primarily, a CoroutineScope is responsible for canceling and cleaning up coroutines when the CoroutineScope is no longer needed. GlobalScope will be set up to support the longest practical lifetime: the lifetime of the process that is running the Kotlin code.

Part of the configuration that you can provide to a coroutine builder is a dispatcher. This indicates what thread pool (or similar structure) should be used for executing the code inside of the coroutine.
