无法在Android的QT上编译

Question

I am new to QT programming and am trying to build a simple program on Android. I have installed QT 5.8, latest Android SDK, NDK and apache ant, but it gives the same error. I searched about this issue and tried using older versions of QT(5.5.1 and 5.7.0) , Android SDK as well as NDK, but its not helping. I tried giving the build path a shorter name, removed all the folders which had spaces in the title and reinstalled everything. Please help.

Answer 1

Check for build.xml in your output path

C:/Qt/Qt5.7.0/Examples/Qt-5.7/quick/demos/build-calqlatr-Android_for_armeabi_v7a_GCC_4_9_Qt_5_7_0-Debug/android-build/

and also check

TEMPLATE = app

in your pro file if this is not there append this.
