Adaptive function-based dynamic application extension framework

A mobile device comprising:

• a wireless transceiver configured to communicate with a developer exchange system over a wireless communications medium;
• a processor;
• and
• a non-transitory computer-readable medium storing instructions for execution on the processor,
• wherein the instructions include downloading and installing a first application from a digital distribution platform, and
• wherein the instructions include, in response to a user of the mobile device navigating to a state of the first application:
• instantiating the state from a first state template of the first application:
• selecting a first function module identifier from a plurality of predetermined function module identifiers, wherein each of the plurality of predetermined function module identifiers corresponds to a first function offered by the first state template, wherein the plurality of predetermined function module identifiers and an associated rank ordering are predetermined by a consuming developer of the first application before providing the first application to the digital distribution platform, and wherein in a first operating mode the selecting is based on a highest-ranked function module identifier in the rank ordering;
• selectively presenting a user interface to the user of the mobile device, wherein:
• the user interface allows the user to activate a second operating mode;
• the user interface allows the user to identify one of the plurality of predetermined function module identifiers;
• in the second operating mode, the selecting sets the user-identified function module identifier as the first function module identifier;
• and
• presenting the user interface is disabled based on a setting specified by the consuming developer;
• transmitting a function module request to the developer exchange system using the wireless transceiver, wherein the function module request includes the first function module identifier, which uniquely identifies a first function module, wherein the first function module was provided by one of a plurality of producing developers to the developer exchange system prior to the function module request being transmitted;
• receiving, via the wireless transceiver, the first function module from the developer exchange system;
• storing the first function module;
• executing the first function module;
• and
• presenting display data generated by execution of the first function module, wherein the display data is presented in an area reserved for the first function by the first state template.
