@moozoom I run in the same paradigm when I try to create a static linked library with Qt targeting Android and latter to use it with JINI on Android Studio. Reading you post I see you have almost the same problem like me with one difference. To me are working as far I use only std library My problem appears when I use QString for example in the library. Looks the static build does not statically includes the Qt framework dependencies. Finally did you find a solution? Me I run with this issue past over one month. Thanks
