Do you use 1R4 or 1R5? Did you install Codeworks from the UE4 engine folder or from Nvidia site packed? Has your Visual Studio credential gone old? In project ‘settings / Platforms / Android SDK / NDK Api level’ does it say “android-19” or something else?

Its 1R5 . I originally downloaded code-works seperatly , but In an attempt t troubleshoot I started again with the UE4 folder one. I only just downloaded VS 2015 COMMUNITY over the weekend… And yes I made the setting in android 19
