• (b) receiving at the client library from the service the list of approved content units and, for each of the approved content units, associated data for placement within the application during real-time use;
• (c) caching the list of approved content units and associated data on a client device having the application and client library for later use;
• and
• (d) using the client library to integrate at least one of the approved content units within the application during real-time use.

A method for previewing content units within an application comprising:

• (a) receiving at a service a new content unit, wherein the content unit is for use in at least the application, and wherein the content unit can be integrated within the application during real-time use and allows for interaction by a user within the application;
• (b) receiving at the service a request from a library for previewing the new content unit within the application;
• and
• (c) transmitting from the service to the library a link that allows the launching of a version of the application that is integrated with the library to load the new content unit for previewing within the application during real-time use.
