The package name should be unique and may contain uppercase or lowercase letters ('A' through 'Z'), numbers, and underscores ('_'). However, individual package name parts may only start with letters.

By default, GeneXus sets this property with the following value:


  • Once the app is published, you will never be able to change this property’s value. The only way to change it is to publish the app again as if it were a different app than before.
  • You should change the default value in order to avoid conflicts with other developers, as the package name must be unique. It’s usually the name of an Internet domain you (or your company) own, in reverse, plus the application name (for example, com.example.myapp).
  • This value can have repercussions in the apps’ ASO.
