java.lang.NoClassDefFoundError: org.apache.pdfbox.pdmodel.PDDocument in Android Studio

[gls prasad]

Hi,

I am getting an error (NoClassDefFoundError:
org.apache.pdfbox.pdmodel.PDDocument) during Runtime in Android Studio
when I used Pdfbox to create a Pdf. I am using jars pdfbox-app-1.8.10.jar and 
commons-logging-1.2.jar.

But it works fine in eclipse. It would be great if you could let me know what 
is the solution for this issue.
