불규칙적인 android java.lang.UnsatisfiedLinkError

A Best way to add External Jars to your Anroid Project or any Java project is:

1. Create a folder called 'libs' into you project root folder
2. Copy your Jar files to the libs folder
3. Now right click on the Jar file and then select Build Path > Add to Build Path, this will create a folder called 'Refrenced Library' into you project, and your are done

By do doing like this, whenever you transfer you project to other Computer, you will not miss your libraries which are being referenced to some space on your Hard drive.
