Thank you again, Mark. You say that "No device that legitimately has the Google Play Store on it will ship with less than 1GB of external storage -- it's a requirement."
This is getting interesting. I checked on a new HTC One V. There the Environment method getExternalStoragePublicDirectory() returns "/mnt/sdcard", which cannot be used for anything. Trying to write there fails. The external memory is also reported as unmounted. There IS about 1 GB memory however - at "/mnt/emmc", (which is writeable) but that directory is NOT returned by any of the Environment methods. This seems to be the required "external" memory that you are referring to, but HOW does an app get to know that?
