Thanks Mark, but I'm not sure if that will work in this case. I have the user press a button that invokes Asynctask to retrieve data from the hardware.
The user is then asked to press a second button to retrieve alternate data from the hardware. If the user presses the second button before the first call to Asynctask returns, then the data will not be complete. I hope this makes sense. Any ideas for this scenario?
