I've had some experience with Qt but none with android in Qt, I've downloaded:
Qt5.5-Android Jdk-1.8
NDK-r14
ant-1.10
SDK r26
and I've given the appropriate addresses to the sections in Tools->Options->Android
However, When I create a brand new project, connect my phone (Samsung Galaxy Note 5, with USB Debugging ON) and select armeabi-v7a(GCC 4.9, Qt 5.5.0), I get the following errors in compile time:
Files/Java/jdk1.8.0_121" --ant C:/Users/Vahid/Downloads/Compressed/apache-ant-1.9.6-bin/apache-ant-1.9.6/bin/ant.bat

I've been stuck in this for a couple of days now and I appreciate any suggestions, Thank you in advance.
