How can I read qr code inside GDK app?

Question

I want to read qr code from GDK app to get authorization token.

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

Answer 1

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);

Answer 3
