How to read or decode QR Code in Android without the use of any 3rd party app?

Question

What are the best ways to read or decode QR Code in Android without the use of any 3rd party app. Suggest me any best API or source code which can be used for integrating in my own app.

Answer 1

Google has a barcode class included in the Google Play services under the namespace com.google.android.gms.vision.barcode. I'm using it myself in a production app and its just great! Its fast, robust and handles all from blurry to damaged codes.
