c++ - QT Widget using OpenCV error deploying to Android -
this question has answer here:
i create qt widget (c++) , use opencv library (c++) , deploy android.
i have installed qt android , necessary files mentioned in http://qt-project.org/doc/qt-5/androidgs.html such ndk,sdk etc. mingw compiler included in qt android didnt have install again.
i have no problem deploying qt widget android. problem using opencv library in qt widget , deploying it.
i have tried 2 options use opencv in qt project:
as qt android comes mingw compiler have compiled opencv library source using cmake , mingw compiler. have included header files , linked libraries in project file of qt . option not work . used method of including , use other libraries such boost , eigen in same way.
i have downloaded opencv android sdk , included it's header files , linked it's libraries in project file of qt. still hasnt worked.
basically want solely code in c++, hence using widget , not qtquick(qml). please can let me know ,if any, of above steps correct , changes have make.
on note know how can speed emulator , have amd processor cant take advantage of intels tools. , can avd settings samsung note 4?
thanks much!!
