Importing ZXing project into Android Studio on Ubuntu

Question

I am very new to Android development. I just setup the environment and using Android Studio. As described in;

I had imported ZXing-2.3.0 project into Android Studio and added core-3.1.0.jar as a library to the project but I still get the below error messages when tried to build project. What could be the problem?

Those are very old instructions. The project docs may be of much more help. https://github.com/zxing/zxing/wiki/Getting-Started-Developing You should be using a recent version, not 2.3.

I'm not clear what you're trying to do. Here, you have downloaded source code and tried to open it as a project directly. The error means what it says: you didn't set up your project to depend on any of the libs the library needs, like Android. Instead, you should have imported the Maven build.

But then you say you're adding the core .jar file but from an entirely different version, 3.1.0. What is going on?

what I am trying to do is importing the ZXing library into Android Studio and then integrating it with my project that I will implement a simple QRCoreScanner. How can I setup this project with library needs? – kyy Feb 07 '15 at 19:37
Then you do not need to download or build anything. You need the core lib or android-integration libs only. Start your own project. – Sean Owen Feb 07 '15 at 20:31
