First, you dont have anything on Android Package Name, dont know if thats the issue but you should fill that one, next have you tried using 23 in mininum an 26 on target ???
Next, could you share a screenshot of the section where you set the paths?? this one:
Try setting NDK and SDK to latest and i used to have a lot of problems when i tried building without running as admin so maybe try running the editor as admin
Also will be helpful if you share a full error log, that line of error i think is not where the problem is
