So, before we get started on solving these issues in our Java binding, let's first clean up the namespaces in the project. Java namespaces are in the form com.mycompany.mylibrary by default, so let's change the definition to match C# more closely. In the Transforms directory of the project, open Metadata.xml and add the following XML tag inside the root metadata node:

<attr path="/api/package[@name='com.google.analytics.tracking   
  .android']" name="managedName">GoogleAnalytics.Tracking</attr>
