Abstract: A system for injection and maintenance of artifact objects within user equipment (UE) is disclosed. The UE comprises a display, a transceiver, a processor, and a memory storing a mobile application comprising a script and an injection engine that, upon being executed, the processor receives a payload comprising a visual object and an artifact object. The UE determines placement of the visual object and the artifact object into the script of the mobile application, injects the visual object and the artifact object into the script, and presents the visual object at an anchor location on the interface. In response to input to remove presentation of the visual object on the display, the UE determines that the visual object is associated with the artifact object, and removes presentation of the visual object from the display. The UE presents the artifact object at a second anchor location on the interface.

Abstract: A mobile communication device. The device comprises a processor, a mobile application that requests content to be rendered, and a content presentation mediation application comprising logic provided by a primary software development kit (SDK) and logic provided by a secondary SDK embedded in the primary SDK. The content presentation mediation application receives a request by the primary SDK from the mobile application for content to be rendered, transmits a request by the primary SKD for content to a content bidding exchange, receives a winning content bid that comprises a content token by the primary SDK from the content bidding exchange, transmits a request by the secondary SDK for content comprising the content token to a content server, receives content by the secondary SDK from the content server, and renders the content received from the content server by the secondary SKD according to rendering logic provided by the secondary SDK.
