Abstract: The application provides a dynamic loading method, and a target file creation method and apparatus to save memory resources. The method includes: loading a dynamic link library file during a running process of an application program on a terminal device, where the dynamic link library file includes a symbol that can implement a functionality in the application program, and the symbol includes a function and/or a variable; reading a first index from a source file of the application program; determining, based on a global symbol table, a first symbol address corresponding to the first index, where the first symbol address is used for indicating a physical address of the symbol that can implement the functionality and invoking the symbol from the dynamic link library file according to the first symbol address, to complete running of the application program.

Abstract: This application provides a method for accessing a network by an Internet of Things device, an apparatus, and a system, and relates to the field of Internet of Things in order to reduce hardware apparatuses need to be provided for an Internet of Things device, and reduce operation steps of a user when it is ensured that the Internet of Things device securely accesses a network. The method includes sending, by an Internet of Things device, an access request message to an access point, where the access request message includes a universally unique identifier (UUID), a service set identifier (SSID), and a first temporary password (pass_tmp), receiving, by the Internet of Things device, an access response message from the access point, where the access response message includes the SSID and a password, and accessing, by the Internet of Things device, a network using the SSID and the password.

Abstract: A mobile device obtains first gateway access information of a smart device. The mobile device generates a corresponding first Wireless Fidelity WiFi hotspot according to the first gateway access information. When the smart device accesses the first WiFi hotspot by using the first gateway access information, the mobile device sends second gateway access information to the smart device, so that the smart device accesses a second WiFi hotspot by using the second gateway access information. In the embodiments of the present invention, on one hand, a physical input apparatus does not need to be disposed on a smart device, and costs of the smart device are reduced. On the other hand, the smart device is connected to a target gateway according to second gateway access information sent by a mobile device, and a probability that gateway access information is maliciously intercepted is reduced.

Abstract: Embodiments of the present invention disclose a touchscreen touch point positioning method and apparatus, and a terminal device, so that scanning time can be effectively shortened, and a point report rate is improved. The method includes: for each target sub-area in a target area, performing, by a touchscreen controller, parallel scanning on horizontal channels in the target sub-area, and determining a target sub-area in which a touch point exists; determining whether the sub-area in which the touch point exists can be divided; if it can be divided, designating the target sub-area in which the touch point exists as a new target area, and repeatedly performing the foregoing operations until a target sub-area in which the touch point exists cannot be divided; determining a horizontal coordinate of the touch point; and determining a vertical coordinate corresponding to the touch point according to vertical channels that receive horizontal channel signals in parallel.
