You don't need source. You don't need JavaDoc.

Why there is a error message like this?

 Failed resolution of:Lcom/itextpdf/text/Document;

you might want to check chapter 3.2.3 Using external libraries here

http://ai2.appinventor.mit.edu/reference/other/extensions.html

and follow the steps in How to Add a Component.

I successfully added library and compiled .aix.
When I'm using the app with that extension only the error coming.

Is there any problem if we didn't added **@useslibraries()**
Thanks @Taifun

Hi Jerin,

If you do not include a @UsesLibraries annotation then the extension packaging mechanism doesn't include the necessary classes in the .aix file. That would explain your error from dex about not being able to resolve com/itextpdf/text/Document.

Cheers,
