[Interest] AndroidManifest Minimum required API not working as expected

From what I can see in the compile output window in QtCreator is:

1) QtCreator calls make on the shadow build directory. This will execute the Makefile generated by qmake and compile the C++ code.
2) QtCreator calls "/Users/nsantos/Qt/5.6/android_armv7/bin/androiddeployqt" --input /tmp/build-drc-Android_for_armeabi_v7a_GCC_4_9_Qt_5_6_0-Release/android-libDRC.so-deployment-settings.json --output /tmp/build-drc-Android_for_armeabi_v7a_GCC_4_9_Qt_5_6_0-Release/android-build --deployment bundled --android-platform android-23 --jdk /Library/Java/JavaVirtualMachines/jdk1.7.0_65.jdk/Contents/Home —gradle

This makes me believe that there is no relation between the Makefile and gradle and/or ant build process
