A method for displaying an application interface, comprising: determining a need to display any application interface in a target application, and obtaining an identifier of N install sub-packages in an application install package of the target application based on the need (101,201), the N install sub-packages being install sub-packages required for displaying the application interface; wherein the target application is an uninstalled application, the application install package of the target application comprises a plurality of install sub-packages, and each of the plurality of install sub-packages is used for realizing a partial function of the target application, the partial function comprises a function of displaying an application interface of the target application, the application install package of the target application is split according to the application interface, such that each of the install sub-packages is used for displaying one or more application interfaces of the target application, or a plurality of install sub-packages are used for displaying one application interface of the target application, the N being greater than or equal to 1 and less than or equal to a sum of the plurality of install sub-packages; obtaining (102,202) the N install sub-packages based on the identifier of the N install sub-packages; running (103,203) the N install sub-packages to display the application interface; and displaying the application interface, wherein the method further comprises: determining a need to display a second application interface on the basis of a currently displayed first application interface, and jumping from the currently displayed first application interface to the second application interface. determining a need to display any application interface in a target application, and obtaining an identifier of N install sub-packages in an application install package of the target application based on the need (101,201), the N install sub-packages being install sub-packages required for displaying the application interface; wherein the target application is an uninstalled application, the application install package of the target application comprises a plurality of install sub-packages, and each of the plurality of install sub-packages is used for realizing a partial function of the target application, the partial function comprises a function of displaying an application interface of the target application, the application install package of the target application is split according to the application interface, such that each of the install sub-packages is used for displaying one or more application interfaces of the target application, or a plurality of install sub-packages are used for displaying one application interface of the target application, the N being greater than or equal to 1 and less than or equal to a sum of the plurality of install sub-packages; obtaining (102,202) the N install sub-packages based on the identifier of the N install sub-packages; running (103,203) the N install sub-packages to display the application interface; and displaying the application interface, wherein the method further comprises: determining a need to display a second application interface on the basis of a currently displayed first application interface, and jumping from the currently displayed first application interface to the second application interface. determining a need to display a second application interface on the basis of a currently displayed first application interface, and jumping from the currently displayed first application interface to the second application interface.
