ahoj!!
Potreboval by som vytvorit nejaky jednoduchy skener QR kodov pre android ale neviem kde zacat
Trtocha som googlil a nasiel som akesi library zxing ktore na to sluzia, viac menej som zacinajuci programator pre android tak som trocha zmateny z informacii ktore som sa docital
Najlepsie by pre mna bolo najst akysi tutorial step by step ako si vytvorit vlastny QR scanner
thx

Re: QR scaner for android
/data/app/com.androidaz.scanner-1.apk si otvor ako zip a pozri sa, či tam máš taký súbor. Buď máš zlý kód, alebo zlú verziu nástrojov.

Re: QR scaner for android
btw neviem ajo tp chces spustat na emulatore, ked ta kniznica je len akesi komunikacne prepojenie s aplikaciou barcode scanner ktoru potrebujes mat nainstalovanu... ale tato chyba s tym asi nic nema... kazdopadne bysom to ale spustal na telefone a nie emulatore (s debugom samozrejme)
