Hello.
I tried to start an app with libMGD.so inside it but the app always crashed instantly when I started it. This problem happened on Samsung S8 and Note 5 (both happens to be in Android Nougat). I always use unrooted devices. This problem doesn't happen when I use it on Samsung S7 and S6.
This is the logcat that might be relevant to my problem (I have to erase some of the phrase because it's work-related) :

Any idea why? Thank you!
Thank you for your answer. I like working with MGD, hope it works out soon!
