I've develop a qml UI, on pc it works but if I build the project for an android device I get these errors from application output:

etc etc (similar errors)@

maybe .svg files are not supported?
Help me
Thanks

xanm

probably you need to add svg to pro file

i had the same error but this helps
@QT += xml svg
QTPLUGIN += qsvg@

and will be better to remove old build dir
