Coroutine Android Best Practices

Best practices for coroutines in Android

Inject Dispatchers

Easier to test.

Suspend functions should be safe to call from the main thread

Using withContext and specify dispatchers in coroutine.

The ViewModel should create coroutines

Hide suspend functions and flows from UI Layer.

The data and business layer should expose suspend functions and Flows

Make your coroutine cancellable

Cancellation in coroutines is cooperative, which means that when a coroutine’s Job is cancelled, the coroutine isn’t cancelled until it suspends or checks for cancellation.

Check your coroutine is active using ensureActive . If your coroutine is inactive, CancellationException will be thrown.
