I am using the RadaeePDF (PDFViewer v3.4) to test reading PDF files from my app. I copied the whole code from the PDFReader demo project. It is working but when i click "ink" or any other button, that item gets removed from the PDF. If i renamed my applicationID in build.gradle file to com.radaee.reader ..the changes persists.
Is it due to using a trial license of RadaeePDF or due to some other problem?
yes the problem is related to the trial license.
The demo app is activated with a Premium license,
If you change the applicationID the license is not activated, the library remains in a restricted mode in which the functions are not enabled.
For the test you can:
1- Use the demo project itself .
2- Give your project "com.radaee.reader" as a package name, this way the premium license will work.
