Wireless communication device having deterministic control of foreground access of the user interface

A method of determining which user interface of a resident application on a computer platform of a wireless communication device controls a display thereof, the user interface, at least, appearing on the display and through which a user of the wireless communication device interacts with the computer platform, comprising:

• displaying the user interface on the display of the wireless communication device, the display configured to be selectively controlled by the user interface of one of a plurality of applications resident on the computer platform;
• receiving a notification event from at least one of an operating system of the computer platform and one of the resident applications;
• determining whether the notification event simultaneously invokes the plurality of applications resident on the computer platform;
• determining, via an arbiter resident on the computer platform, when the notification event simultaneously invokes the plurality of applications resident on the computer platform, which application of the plurality of resident applications controls the display based upon predetermined criteria;
• and
• overriding the arbiter's determination of which application of the plurality of resident applications controls the display based upon priority data included within the plurality of resident applications.

A non-transitory computer readable medium having stored thereon processor-executable instructions configured to cause a processor to perform operations, comprising:

• displaying a user interface on a display of a wireless communication device, the display configured to be selectively controlled by the user interface of one of a plurality of applications resident on a computer platform of the wireless communication device;
• receiving a notification event from at least one of an operating system of the computer platform and the one of the resident applications;
• determining whether the notification event simultaneously invokes the plurality of applications resident on the computer platform;
• determining, via an arbiter resident on the computer platform, when the notification event simultaneously invokes the plurality of applications resident on the computer platform, which application of the plurality of resident applications controls the display based upon predetermined criteria;
• and
• overriding the arbiter's determination of which application of the plurality of resident applications controls the display based upon priority data included within the plurality of resident applications.

A wireless communication device, comprising:

• means for displaying a user interface to a user of the wireless communication device, the means for displaying configured to be selectively controlled by a user interface of one of a plurality of applications resident on a computer platform of the wireless communication device;
• means for receiving a notification event from at least one of an operating system of the computer platform and the one of the resident applications;
• means for determining whether the notification event simultaneously invokes the plurality of applications resident on the computer platform;
• means for determining, when the notification event simultaneously invokes the plurality of applications resident on the computer platform, which application of the plurality of resident applications controls the means for displaying based upon predetermined criteria;
• and
• means for overriding the determination of the controlling application based upon priority data included within the plurality of resident applications.
