This is the line with the actual issue:
C:\NVPACK\android-sdk-windows\ ools\ant\build.xml:538: Application package ‘ArchitectIN NavSys’ must have a minimum of 2 segments.\par
This means the Package Name (Android Package Name in the Android Project Settings) doesn’t follow the proper format. It needs to be something like: com.mycompany.[PROJECT].
[PROJECT] will be replaced with the project name. If you want something different you can change this, but you must have at least 2 valid ids separated by a period.
