    the problem was in this : "-android-ndk ANDROID_NDK_PATH" I had to provide the full path or use %ANDROID_NDK_PATH% as the string was passed as it is not as an environment variable
    I think the error should be : can't find ndk path

      So you succeed building Qt ?

            Did you check if you have that file somewhere ?

              @deveLoper5122 said in building qt 5.9 on windows for android results in 'ERROR: Cannot detect Android NDK toolchain':

              qfontengine_ft_p

              I have it in E:\qt-android-source\qt-everywhere-opensource-src-5.9.2\qt-everywhere-opensource-src-5.9.2\qtbase\src\platformsupport\fontdatabases\freetype

              but don't know why the compiler didn't resolve it

                That's a pretty long path for not much benefit.

                I'd recommend shortening it and also make an out of source build.

                  I can't change the dir now after I started building , I had to rebuild from scratch again right ?

                    Yes, that's correct.

                      I could change the dir with a symbol link to qt base and resumed the build again

                          the file exists but the javac doesn't seem to be redircted with the symbol link so I have to restart the whole build with a shorter path
