Abstract: A communication device configured to unobtrusively display media content. The processor receives an indication of a state transition of a first Activity and detects a first user interaction with the user interface, which may be done by inspecting a first operating system method called in relation to the first Activity.

A context object associated with the Overlay is created to contain an Activity context associated with a state of the Overlay during the delay period. The Activity context is transferred to the backing Activity and Activity-supported functionality of the Overlay enabled.

Abstract: A method of displaying media content through a user interface of a communication device using an Activity-based Overlay technique. The method includes detecting a first user interaction with a user interface and responsively initiating a timer, the timer being configured to expire upon elapsing of a predefined delay period. An Overlay containing the media content is then rendered on a display of the user interface. The method further includes monitoring, during the predefined delay period, the operating system in order to detect a second user interaction with the user interface. Upon expiration of the timer, it is determined whether a detection of the second user interaction with the user interface occurred during the predefined delay period. A backing Activity associated with the Overlay is then invoked based upon this determination.
