1) QXml works without a plugin. So that's not it
2) It looks like all of the prerequisites are loaded. Here's loading
the QXml library:
D/dalvikvm(20264): Trying to load lib
/data/data/org.qtproject.example.test_mage/lib/libQt5Xml.so 0x2c665238
D/dalvikvm(20264): Added shared lib
/data/data/org.qtproject.example.test_mage/lib/libQt5Xml.so 0x2c665238
Everthing looks ok with that. It's only later that the library is loaded:
E/dalvikvm(20264):
dlopen("/data/app-lib/org.qtproject.example.test_mage-2/libmage.so")
failed: dlopen failed: cannot locate symbol
"_ZN18QXmlDefaultHandlerC2Ev" referenced by "libmage.so"...
