cannot resolve symbil intent android studio

This library offers scanning UPC-A, UPC-E, EAN-8, EAN-13, QR Code, RSS-14, RSS Expanded, Data Matrix, Aztec, PDF 417, Codabar, ITF, Codes 39, 93, and 128. So after some R&D online I came across an awesome library called Zxing (Zebra crossing)

What am I doing wrong?Ī little addition to other answers here, for anyone having the same error while using the right lib version and the right class. However I can only use ActionBarActivity. I have compile ':appcompat-v7:22.0.+' in dependency list of my 'app' module and rebuilt project several times. Unfortunalty Android Studio 'says' that itĬannot resolve symbol 'AppCompatActivity' I've created blank project and tried to create Activity which extends AppCompatActivity.
