thanks man. im still getting some issues but they seem completely different.
The errors seems to be:
PlayLevel: C:\NVPACK\android-sdk-windows\tools\ant\build.xml:694: Execute failed: java.io.IOException: Cannot run program “C:\Users\Simon\Documents\Unreal Projects\Duality\Intermediate\Android\APK\JavaLibs\google-play-services_lib_rev19${aapt}” (in directory “C:\Users\Simon\Documents\Unreal Projects\Duality\Intermediate\Android\APK\JavaLibs\google-play-services_lib_rev19”): CreateProcess error=2, The system cannot find the file specified
Just looking around now to see if i can get to the bottom of it.
