Yeah, that runs counter to the behavior we generally accept. This entire approach is also why I'd much rather we do these APIs as Intents. Doing it as an Intent allows the host to provide a host-OS/Device based Intent provider if it's available, but allows the user to connect a web service or Bluetooth device or whatever if they want to interact with the application but their hardware/OS doesn't have the necessary support. --------------------------------------------------------------------- This transmission (including any attachments) may contain confidential information, privileged material (including material protected by the solicitor-client or other applicable privileges), or constitute non-public information.
