Hello,
I am using AIDL to pass objects from an Activity to a Service and am getting some strange behavior. To my understanding, the idea behind AIDL is to create an interface in a .aidl file, which android will then implement (partially) in a dynamically generated class. Android will create an abstract class called Stub, which you the...

I built the project against 1.5, but I only have a device with 1.5 to test on. Since I built o...

I'm using Win7, if that changes anything.

Hi,
I've got a ListView with a custom BaseAdapter. The list items contain CheckBoxes that need to represent a property from a database.
