The current state of art for over-the-air (OTA) provisioning typically consists of a rigid set of operations that are suited to deliver a fixed content type. The runtime environment on the terminal is designed to handle a limited set of predefined content types and incapable of any content-adaptive or customized provisioning by the content provider or publisher. A system and method is provided for adaptable provisioning of an application program on a runtime environment of a terminal. The application includes generic application content. The method comprises the steps of configuring a provisioning API set including a generic API, such that the generic API is addressable by at least two dissimilar content types of the generic application content. The method also obtains an enabler related to a selected content type of the generic application content, such that the enabler is configured for executing provisioning instruction requests for the generic application content according to the selected application content. The method also provisions portions of the generic application content having the selected application content by using the enabler to access the generic API.
