Every time I see
Cannot find C:\Users\xxxxx\AppData\Local\Android\sdk\buil d-tools\tools\ant\build.xml people are using Android Studio.
The latest version, doesn't support Fusion, since it's deleting the Ant folder.
Either find the version from 2 years ago,
remove Android studio and download these 2 and install API 24
on that page
Windows x86 189.36 MB jdk-8u121-windows-i586.exe (There might be a newer version)
and the SDK: http://filehippo.com/download_android_sdk/tech/
once you you install the SDK, start the manager and download the API's
