First of all I'd like to say what a fantastic piece of kit App Inventor looks to be. I'm a web developer by profession and I think that Google have done a great job in opening up programming to the masses. Unfortunately I'm having a bit of an issue transferring media to the phone through the Blocks Editor. I am following the Hello Purr tutorial and I keep getting the same error message for my HTC Desire - 'Error sending media to the phone'. Any help on this would be appreciated.
