TOPIC:

I found that your SDK guid contains below thing.
--copy “com.radaee.view” package to your project(optional)
“com.radaee.view” contains view classes for PDF.
It is not necessary to copy these files, if you are coding PDF view by yourself or APP which does not render pages.
I searched the demo projects,but it doesn't contain the any packaged named com.radaee.view package ?

in the demo project, this package is inside the jar file, if you have a professional or premium license, you can get the sources of this jar from www.androidpdf.mobi/shop/key-request
Enter Order Reference and PIN then Order Status, then choose the correct wrapper from the Available releases drop box…
after downloading it you will need to copy the content inside com.radaee folder and remove the jar.
