Is there any build in methods to read QR codes in GDK?

QR code could be obtained from bitmap using this ZXing library

To get the bitmap Glass camera intent could be used.

This worked for me.

Intent objIntent = new Intent("com.google.zxing.client.android.SCAN");
objIntent.putExtra("SCAN_MODE", "QR_CODE_MODE");
startActivityForResult(objIntent, 0);
