We use the deInitScanner() on the onPause function to release scannner according to BarcodeSample1
My application use emdk3.1,when used on my device(TC700H),it works. when used on customer's device(TC700H) it crashes
down itself when onPause() called on BaseActivity.
 
if i remove the scanner release code,it works on customer's TC70 very vell. i wonder how the application crashes down itself.
