I am using metaio sdk for read qr and bar-code.

In Google glass i am not getting perfect result because google glass dont have auto focus.

But google glass wifi qr code scaning is good without auto focus. I require the same functionality like wifi qr code scanning in my app. and which library use for wifi qr code scanning i am not getting.

How can i get best solution for large distance scanning qr code like wifi qr code scanning in google glass.

  • can you elaborate on "large distance" scanning 2-3 feet? Also is your question about scanning to input information into your app like a user or password – StanleyZheng Mar 19 '14 at 15:33

You can utilize utilize a version of the ZXing open source library found here https://github.com/zxing/zxing. This possibly is the same library used on the glass for 2D decoding

You can call and pass via intent to get your information in your app

 Intent intent = new Intent("com.google.zxing.client.android.SCAN");
 intent.setPackage("com.google.zxing.client.android");
 startActivityForResult(intent, QR_CODE_MODE);

There are two elaborated examples related to this question How to scan a QR code using Google Glass?

edit: you need to download zxing's android client. You can get the latest copy that has the XE10 video scramble from their master branch.

https://github.com/zxing/zxing

Build the zxing/android package folder (eclipse/ant/android studio) and install your application) should work as normal.

XE10 bug was fixed here: https://github.com/zxing/zxing/blob/39780fb86f3f887eb438edd58b323afe6142d669/android/src/com/google/zxing/client/android/camera/CameraConfigurationManager.java

  • but this not work for google glass.App is crash when use Intent intent = new Intent("com.google.zxing.client.android.SCAN"); intent.setPackage("com.google.zxing.client.android"); startActivityForResult(intent, QR_CODE_MODE); – Nehalkumar Mar 20 '14 at 09:26
  • this solution requires that you have the zxing client application installed on the glass. Have you added it? – StanleyZheng Mar 20 '14 at 11:24
  • no i dont added this if you have then send link or code to me. – Nehalkumar Mar 20 '14 at 11:47
  • https://code.google.com/p/zxing/downloads/list download "barcode scanner4.x.apk" then if you have adb installed and glass pluggedin. adb install 'apk name' – StanleyZheng Mar 20 '14 at 12:08

  • when i install "barcode scanner4.x.apk" and run this code "Intent intent = new Intent("com.google.zxing.client.android.SCAN"); intent.setPackage("com.google.zxing.client.android"); startActivityForResult(intent, QR_CODE_MODE);" then glass camera is different color like rainbow – Nehalkumar Mar 20 '14 at 12:55

  • OK @Nehalkumar sorry, it looks like the 4.5x doesn't have the latest changes that has that incorporated but their master branch does. https://github.com/zxing/zxing> Ill also update my instructions clone, build and install the android package and it will be fixed – StanleyZheng Mar 20 '14 at 13:15
