I'm stumped by the non-action of the expansion file download function of the Google licensing plugin. After calling checkExpansion() the event listener for Event.DOWNLOAD_REQUIRED is triggered, which seems to correctly recognize that the Google has an expansion file for the app with the given key, and that it is not present on the device. My understanding was that the download would begin in that case, and I assumed there would be events handled by the DOWNLOAD_STATE and DOWNLOAD_PROGRESS listener. None of those event listeners are being triggered, and I see no events at all after DOWNLOAD_REQUIRED.
I'm testing on an Android device, with a Gideros player app built with the in-app billing and Google licensing plug ins, and that app is in debug mode in Eclipse. The LogCat shows nothing from the time the player is up and running. I'm not seeing anything showing up in sdcard/Android/obb where I would expect the expansion file to be downloaded on the device.
Anyone have any ideas what I'm missing?
