http://code.google.com/p/zxing/ Zxing (pronounced "zebra crossing") is a open-source, multi-format 1d/2d barcode image processing library implemented in Java, with ports to the other languages. We are on using the built-in camera on mobile phones to scan and decode on the barcodes, device without G with a server. However the project can be used to encode and dec

Through the analysis of the "fix barcode" zxing Project source code interpretation (2.3.0 version, Android section), it is now possible to achieve the ultimate goal: streamlining barcode scanner and separating the encoding and decoding into two separate sections for quick integration into your project in the future.CodingIn the previous analysis, the coding secti

Brief IntroductionThe recent widget project used a camera to process barcodes, and Zhang Shi recommended zxing, a source project, and did a simple research.Zxing is an open source Java class Library for parsing 1d/2d barcodes in multiple formats. The goal is to decode the QR code, Data Matrix, UPC 1D Barcode. It provides clients under a variety of platforms including: J2ME, J2SE, and Android.Currently,

This simple question bothered me for nearly two hours, the main is the official document did not find the demo, that can only use search engines, see other programmers to write the program, but found everywhere is a pit, see four or five examples, no one can be normal operation, all the error, after one hours of trial, only to finish. Not much to say, directly on the screenshot and code. First, add the Zxing.dll reference to the project (zxing.dll download address http://www.jb51.net/dll/zxing.

automatically picks the best scanning library from the above two, depending on the//Android version and what is a vailable. Compile ' com.journeyapps:zxing-android-integration:2.0.1@aar '//Version 3.0.x of zxing core contains some code is n OT compatible on Android 2.2 and earlier. This mostly affects encoding and but you should test if you are to support these versions. Older versions e.g. 2.2 may also work if to need support for the for older A

Modified based on this source code. Http://blog.csdn.net/ryantang03/article/details/7831826 In addition to the QR code image generation function that he added, the package is saved. The sound effect after scanning is removed, saving a sound file. With the flashlight function removed, scan the QR code at night to go to bed quickly. Saves a class. Scanning timeout is removed, saving two classes. Removed the title bar of the scan interface, saving an image file. For ease of use,
