Aggregation doesn't return any data in onSuccess callback but data is shown in HttpTransport logcat...
Awaiting some response? Is this a real bug or something wrong at my end?

Hello Pankaj,
We are currently working to test this issue now. I will get back to you on this shortly.
Thanks,
Hi Damien
Any update on this. I see the issue anytime there is a array that comes in response. Even though the HttpTransport response shows that the data has arrived, the Kinvey client library for android is not able to serialism it correct to a json object and so the onSuccess reports a null.
Thanks
Pankaj

Hello Pankaj,
The reason that this isn't working is due to the fact that you're calling:
AsyncAppData<GenericJson> error = getKinveyClient().appData("00CCUZones", GenericJson[].class);
When you should be calling:
AsyncAppData<GenericJson[]> error = getKinveyClient().appData("00CCUZones", GenericJson[].class);
You are correct in that the library is behaving poorly (onSuccess shouldn't be passed a null, it should instead be failing) but we are confident that this should resolve the issue in the near term.
Let me know if this handles your issue.
Thanks,
Thanks it worked.

I'm with the same problem. Putting GenericJSON[] in AsyncAppData<GenericJSON[]> and appData("expenses", GenericJSON[]) gives an error:
----> java.lang.ClassCastException: com.google.api.client.json.GenericJson[] cannot be cast to com.kinvey.java.model.Aggregation$Result[]
at com.kinvey.java.core.KinveyAggregateCallback.onSuccess(KinveyAggregateCallback.java:21)

Making an aggregation count call on android doesn't return anything in the onSuccess. Even though onSuccess is called the data is empty. While debugging and looking at HtttpTransport log, I do see the data correctly. Using the same aggregation count on iOS/RestAPI etc works fine.
