HUAWEI DEVICE CO., LTD.

A method for identifying a device comprising generating, by a control device, an identification identifier of a multimedia device according to device description information of the multimedia device, sending the identification identifier to the multimedia device, so that the multimedia device displays the identification identifier, acquiring, by the control device, the identification identifier displayed by the multimedia device and an appearance image of the multimedia device, and acquiring the device description information according to the identification identifier displayed by the multimedia device, and associating, by the control device, the device description information with the appearance image of the multimedia device, so that a user equipment identifies the multimedia device according to the appearance image.

A system function invoking method includes acquiring an installation package of a first application program, granting a first permission of a system to the first application program according to the installation package, where the first permission is used to, when the first application program is in a running state, forbid a second application program from invoking at least one system function. The method further includes running the first application program, and forbidding the second application program from invoking the at least one system function.

Embodiments of the present invention disclose a method, an apparatus, and a system for supporting multiple IMSIs. The method includes: receiving a response message that is returned by a server in response to an IMSI update request message and transmitted by a user terminal; and executing an IMSI update operation for a smart card according to information carried in the response message, where the smart card is a smart card supporting multiple IMSIs, and the IMSI update operation for the smart card includes: an operation of adding an IMSI in the smart card or an operation of deleting an IMSI from the smart card. The foregoing technical solution may dynamically update an IMSI in the smart card, thereby avoiding a phenomenon that one user must occupy multiple IMSIs all along, improving a utilization ratio of IMSIs, and saving IMSI resources.

Embodiments of the present invention provide a method for sharing an application between terminals, and a terminal, so as to facilitate user operations at a receiving end. The method includes: generating, by a first terminal according to an application that has been installed, a shared application installation package of the application; sending, by the first terminal, the shared application installation package to a second terminal, so that the second terminal installs the shared application installation package; determining, by the first terminal, shared data of the application that has been installed, where the shared data is data that is from an application server and required for the application to run; and sending, by the first terminal, the shared data to the second terminal, so that the second terminal uses the shared data when running the shared application. In the embodiments of the present invention, when sharing an application, two terminals not only share an installation package of the application, but also share shared data of the application, so that a receiving end does not need to download the shared data from an application server, which facilitates user operations at the receiving end and improves user experience.

A dynamic interface layout method includes that a width of a screen of an electronic device is divided into a plurality of columns. The electronic device displays a first interface on the screen. After detecting an interface refresh signal, the electronic device obtains a first column quantity corresponding to a width of a second interface to be displayed after refreshing. The first column quantity is a quantity of columns included in the width of the second interface. The electronic device determines a second column quantity according to a layout rule corresponding to a first element on the second interface. The second column quantity is a quantity of columns included in a width of the first element. The electronic device displays the second interface on the screen.

An application-level memory control group of a first application may be created when the first application is opened. An anonymous page of the first application is added to a least recently used linked list of the application-level memory control group, and a file page of the first application is added to a global least recently used linked list. An application-level memory control group is created in a dimension of an application, and an anonymous page of the application is managed in a refined manner. In addition, a file page of the application-level memory control group may be managed based on a global least recently used linked list.
