Abstract: A device and method for updating mobile Social Network Service (SNS) user presence status, wherein, a SNS client module in a mobile user terminal sends a registration request to a subscription publishing module to apply for subscribing a profile state change notification; the subscription publishing module records ID of the SNS client module in a notification list for registration, a user switches profiles in a profile interface module; the profile interface module sends an event notification to a background module; the background module reads the content of the new profile entry and notifies the subscription publishing module of the content of the new state; the subscription publishing module queries the notification list and notifies the respective SNS clients one by one of the update; the SNS clients publish the content of the new state in the respective SNS systems.

Abstract: The present invention provides a method and a terminal for loading picture resources by a JAVA virtual machine. The method includes: obtaining the picture resources required by the JAVA virtual machine, decoding the picture resources into original data and then storing the original data; and reading the original data of the picture that requires loading to load the picture after receiving a loading picture event in normal operation of the JAVA virtual machine. According to the present invention, the picture loading speed of the JAVA virtual machine can be controlled, thereby guaranteeing the start speed of the JAVA virtual machine.

Abstract: The present invention discloses a method for implementing management of application information in a mobile phone and an application manager, wherein, the method includes: after the mobile phone is powered on, its application manager reading application information from a file system and caching the application information in background. In the present invention, when the user starts up the application manager, the cached application information can be directly read and displayed, and does not need to be loaded from the file system, thus greatly improving the speed of displaying the application information, and thereby greatly enhancing the user's experience. In addition, when the user updates the application and inserts a memory card into the mobile phone, the information is synchronously updated in background by the application manager to be provided to the user for obtaining and displaying at any time.
