Trying out the SDK/Text Extraction

Hello,

I am considering buying a license for Android. However, some criteria needs to be met before I do. I have two questions:

Do I need to Purchase a license before I can start implementing AndroidPDF in my application? I wanted to ensure it works with what I am developing before releasing the app. In other words: I want the standard features for development purposes only.

Also, I could not find out how to extract text from a PDF? How would I go about extracting the contents? What Class is used? Which methods?

Thanks in advance

see:
Page.ObjsStart()
Page.ObjsGetCount();
Page.ObjsGetString();
this need at least a standard license actived.
you can test it in demo peoject which actived a premium license binding package "com.radaee.reader"
