i have windows 7 professional 64 bit
I think it has to do with the barcode scanner.I have this error appearing all of a sudden:
Convert byte code - optimized dex. Error
It is a very small app with about 7 views and one page. It happened when I all of sudden was told that I do not have the core-3.2.1.jar library, which I then loaded and then this friend started to bug me.
