如何将Zxing库包含到android项目中？

Question

I have read some answer for this question in stackoverflow, but it is not working for me. I have already a project, and now I want to integrate QR Code and barcode reader into my project.

I downloaded the zip file from: core-2.2.zip

I didn't find any "core.jar", I read that I have to integrate files added in "core" folder. Do I have to add all classes to my project (the whole folder)? or do I have to create a jar file with that folder?

I am using Android Studio. Any one can help me? thank you

Answer 1

There is indeed an Android application that is part of the ZXing project. It uses the core module released in maven central. If you have a maven project (which is unlikely for most Android applications) you can add the following dependency to your pom.xml file:

<dependency>
    <groupId>com.google.zxing</groupId>
    <artifactId>core</artifactId>
    <version>3.2.0</version>
</dependency>

for a Gradle project:

compile 'com.google.zxing:core:3.2.0'

or you can directly download the compiled .jar from here .

Please, notice that this answer refers to version 3.2.0 which is the latest stable one. Version 2.2 could be similarly obtained.

Answer 2

For QRCode reading you can also use Google Play service 7.8 and beyond. You may check this link from Google .

Answer 3

What you should do is to include a jar, you can not be downloaded. At first when you try to take zxing had the same problem, luckily I found the jar and I could download it. You have to verify either version which you need.

core

I have not worked in Android Studio, this is in eclipse but I imagine it must be the same way.

What you need to add it is the full project zxing to your project as a library to the main project. Activity and create a layout that include this library.

Which is also the default is:

public class Validador extends CaptureActivity {

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.validador);
}

}

Layout :

<FrameLayout
android:layout_width="wrap_content" 
android:layout_height="wrap_content"
android:layout_gravity="center">
    <include layout="@layout/capture"/>
</FrameLayout>
