Step by step to setup zxing 3.2.1 in eclipse

  1. Download zxing-master.zip from "https://github.com/zxing/zxing"
  2. Unzip zxing-master.zip, Use eclipse to import "android" project in zxing-master
  3. Download core-3.2.1.jar from "http://repo1.maven.org/maven2/com/google/zxing/core/3.2.1/"
  4. Create "libs" folder in "android" project and paste cor-3.2.1.jar into the libs folder
  5. Click on project: choose "properties" -> "Java Compiler" to change level to 1.7. Then click on "Android" change "Project build target" to android 4.4.2+, because using 1.7 requires compiling with Android 4.4
  6. If "CameraConfigurationUtils.java" don't exist in "zxing-master/android/app/src/main/java/com/google/zxing/client/android/camera/". You can copy it from "zxing-master/android-core/src/main/java/com/google/zxing/client/android/camera/" and paste to your project.
  7. Clean and build project. If your project show error about "switch - case", you should change them to "if - else".
  8. Completed. Clean and build project.
  9. Reference link: How to use Zxing in android
