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. Systems and methods are provided for adaptable provisioning of an application program on a runtime environment of a terminal. The application includes generic application content. One 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; obtaining 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; and provisioning portions of the generic application content having the selected application content by using the enabler to access the generic API.
