I had this error before when I use Zxing library.

Now I can explain what I did and how I fix this.

I have imported zxing library into my project and also imported one lib(called GZxing) that contains within zxing library. When I run application I have same error as you.

Solution:

I deleted zxing library and keep only GZxing library and it works fine.

I assume you could have some class or files that already exist on your project.

2 or more jar files may contain same class and methods. so getting this kind of error, to resolve it need to remove common jar files which contain same class details. and make project clean and run again.this may helps you.
