 To use a different ObjectServer, simply put the server IP Address into
 the `build.gradle`, as indicated in the comments, on the lines like this:
 
-    buildConfigField "String", "OBJECT_SERVER_IP", "\"${host}\""
+    def rosUrl = "<INSERT_REALM_OBJECT_SERVER_URL>"
 
 For instance:
 
-    buildConfigField "String", "OBJECT_SERVER_IP", "192.168.0.1"
