Note: As a real-world example of async(), you can check out this part of the [Now in Android app](https://github.com/android/nowinandroid). In the [SyncWorker](https://github.com/android/nowinandroid/blob/main/sync/work/src/main/java/com/google/samples/apps/nowinandroid/sync/workers/SyncWorker.kt#L65) class, the call to sync() returns a boolean if the sync to a particular backend was successful. If any of the sync operations failed, then the app needs to perform a retry.
The link to SyncWorker.kt links through a non existant java folder, should be kotlin
