OK, thanks... that explains it... my Nexus 7 doesn't have an SD card.
also, the IDE screenshot capture utility doesn't work over the B4A bridge... and I can't figure out how to link the IDE to my Nexus 7 via USB and do this... might not even be possible any more, although I've seen some info indicating it was once possible.
Finally, I tried running the IDE emulator, ( to run my program on the PC, inside the IDE ) but it won't load the AVD profile for the Nexus 7... it crashes before it finishes...
So I guess I'm out of options... at least on this tablet.
Thanks again.
