How actual code looks like? Because this from sample doesn’t make sense itself, or you have multiple async there?

I would recommend instead of wrapping with Dispatcher.IO whole block, write an extension fucntion which does it for GeocodingApiRequest. Like:

suspend fun <T> GeocodingApiRequest<T>.awaitAsync() = withContext(<http://Dispatchers.IO|Dispatchers.IO>) {
   await()
}

It’s not so different, but instead of wrapping to IO where you use it, in final code you use already async code and don’t worry about dispatchers

You mean I can ignore this warning?

,analysis is not advanced enough to understand that this async uses the same dispatcher as parent scope\

There’s no extra code. It’s the same code in a suspend function.

But in this case you don’t need async, it does nothing, just unnecessary wrapping withContext is enough

in 99% cases async{}.await() (so await right after async creation) is unnecessary and can be replaced withContext

because essentially this is a kind of Future, so no need to block at all and just use suspendCancellableCoroutine

It has callback-based async api: https://googlemaps.github.io/google-maps-services-java/v0.1.2/javadoc/com/google/maps/GeocodingApiRequest.html#setCallback(com.google.maps.PendingResult.Callback) And it supports cancellation: https://googlemaps.github.io/google-maps-services-java/v0.1.2/javadoc/com/google/maps/GeocodingApiRequest.html#cancel()
