Hi!
Resgisters is the "logcat" only. My temporary solution: Copy to my lib
folder of the same template library in the qt android:
% adb push libgeodroid.so
/data/data/eu.licentia.necessitas.ministro/files/qt/lib/
So it worked! possibly patch!!!
Using the necessitas when you add the tag "bundled_libs" with the
library, and recompile the application to tag "bundled_libs" is erased
by the necessitas.
So I have to manually re-add and run: "ant debug"
Part of the application now running log:

This way is working but not an elegant solution!
