Hi Radaee Team,
Our company has an Android app that uses Radaee PDF for it's main functionality. Previously, we used older version of this library. It runs smoothly, and we happy with the functionality. And it's there on Google Play for about 1 and a half year.
These days, I tried to obvuscate this Android application, as part of our company;s policy. We use ProGuard. At the first try, I saw a problem with Math Float or something, I guess a class used by the old version Radaee PDF is depreceted, and Android Studio suggest me to use latest version of the library. Ok, then I download the latest release Radaee Android SDK, and follow the tutorial. I could build it, and I've called Global.Init() method from my PDF viewer activity, and we use our purchased profesional license. But unfortunately, when we ran the app, there is a watermark said 'Rendered by radaee ...' in the PDF viewer (that is likely indicates that it is failed to activate the license).
It was running good without watermark when I set minifyEnabled to false in gradle config (which means, we don't use ProGuard).
How we solve this issue? Obvuscation is part of our company policy.
FYI: I didn't change the old activity code.
