When LibraryPath::PluginsPath requested using QLibraryInfo::path, a unexisting path is returned. The path points to a .../lib/plugins directory which does not exist on Android device by default. On Android the plugins are added directly to the .../lib directory.

Breadcrumbs for future debuggers:
The current impelentation uses path given is created from
INSTALL_PLUGINSDIR is created in QtBuildPathsHelper.cmake
qconfig.cpp is created from qconfig.cpp.in in QtQMakeHelpers.cmake which fills qt_configure_strs via QT_CONFIG_STRS.
the path given by QLibraryInfo::path is from qt_configure_strs.
