Error when linking libnative_camera_r2.2.0.so - QT + OpenCV4Android

edit

Hi,

I've been trying to run OpenCV4Android 2.4.8 along with QT 5.2 to create an android app, but I got stuck with the following error when deploying the app:

/dalvikvm(16441): dlopen("/data/app-lib/org.app-1/libnative_camera_r2.2.0.so") failed: Cannot load library: soinfo_relocate(linker.cpp:975): cannot locate symbol "_ZN7android6Camera17setPreviewDisplayERKNS_2spINS_8ISurfaceEEE" referenced by "libnative_camera_r2.2.0.so"...

My .pro file looks like the following:
