Hello! I am Android developer, and i would ask You question about Pdfbox usage in app, which I am currently developing. I have chcecked license, but still I am not sure, if I can use Pdfbox in my app with ads in? It is just app which will be placed in Google Play, and i want to monetize it with ads inside. Can You explain me, if I can use Pdfbox, based on current license, and do I have to place any disclaimers or something? Thank You for help, Sincerely, Michael.
