How to active license?

I got a license
What should i do to active license?
I modify this line in Global.java But didn't work

there are 3 license type in version 2.0
"active" method in old version renamed to "activeProfessional"
please check spelling for your paramaters, It case sensetive.
and ensure that you have no extra blanks in your paramaters.

I download pdfreader2.03.zip and import Eclipse
Run perfectly on my handset
I modify Global.java Didn't work
Then i modify another line Didn't work

i think you had some misunderstood about license.
the demo project can only actived with package name "com.radaee.reader"
it is application package name.
if you change license in demo project, the watermark will be displayed.

to remove watermark:
you should create your application with package name you requested.
the license you purchased must bind to package name you requested.
active function first check <package name>, <company name>, <mail>, <serials>.
then access "data/data/<package name>".

Mark, may you send us your license details to [email protected]?

It will be sufficient to get the registered email address during purchasing operation.

We will check it and send you back the correct source code you should put in your application.

Thank you very much
I got it now
Watermark had been removed
