Core loading method and device

An embodiment of the invention provides a core loading method and device. The core loading method includes receiving a user-interface installation file and/or a core file during updating, wherein the user-interface installation file includes a user interface module and an interface adapting layer module; installing the received user-interface installation file; dynamically loading corresponding function files and object base files through the interface adapting layer module during running of applications. By the core loading method and device, the purpose for dynamically loading the core functions and files is achieved, so that the user interface and the core are separated architecturally, and any one of the user interface and the core can be independently upgraded and updated, installation is more convenient, and download flow is saved. In addition, the core can be loaded and called by the user interfaces of the applications by importing the corresponding interface adapting layers into the user interfaces of the applications, so that the core is universal in use and system resources of mobile terminals can be greatly saved.
