Get device /Android or iPad/ default font scale

[A Former User]

Hi all.

I would like to obtain the device default font scale when starting the app:
For ex in case of Android device there are a few hardcoded font size values: normal, large etc.
I have tried to get from Qt from default font object without success.
Now I am trying to write a java class for obtaining font sizes: First problem: I am not able to call non static java method from Qt. In java I am not able to obtain font size from static method....

Please give me some hints to solve this problem.
Thank you very much!
Have a nice day, bye,
Bence
