在Android studio中添加ZXing android项目作为库

Question

I am making an app in android studio that uses a bar code scanner. I am using the Google ZXing lib. I downloaded the zip, opened the project and added the core.jar file as instructed but the tutorial was for eclipse and there is no option to add as library in android studio. so I am stuck on how to add it. any help would be greatly appreciated :)

Answer 1

Simple way with mvn repo:

dependencies {
   compile 'com.google.zxing:core:3.0.0'
}

The more work version without mvn repo:

dependencies {
   compile files('./libs/zxing/core.jar')
}     

So whichever version you pick, look for the dependencies block in your build.gradle, then add in the appropriate compile line. Remember to add it into the build.gradle for your app module, not the root build.gradle.

Sample directory layout: /approot

/approot/build.gradle

/approot/myfancyapp

/approot/myfancyapp/build.gradle <--- this one!

/approot/myfancyapp/libs/zxing/core.jar <--- put the jar here or any path, just an example.

Answer 2

如果将编译文件（'libs / core.jar'）添加到build.gradle，则唯一需要做的就是单击工具栏中的“使用Gradle文件同步项目”按钮。
