Starting from September the 1st we will apply strict SSL security level on the whole website.
As per our knowledge it could bring to some compatibility issues with very old browsers and operating systems.
We've just published the B4A integration library that will enable you to use our PDFViewer SDK in your own applications.
The library is available with full sources here
It's licensed as Apache2.
Actually the B4A library is distributed as is without any direct support from our Support Team.
We will support only the classes belonging from our Android Eclipse and Android Studio interfaces.
