  • Patent number: 11947974
    Abstract: Disclosed are an application start method and an electronic device. The method includes: obtaining, by a SystemServer process in an electronic device, a start message of a first application; sending, by the SystemServer process, a creation request for an application process to a daemon process in response to the start message, where the creation request includes application information of the first application; creating, by the daemon process, the application process for the first application in response to the creation request, where the application process includes a first thread and a second thread; executing, by the application process, the first thread and the second thread in parallel, where the first thread executes initialization of a main thread of the first application, and the second thread creates a first class loader according to the application information to load a class file of the first application.

  • Patent number: 8357796
    Abstract: A simple, inexpensive, and efficient method for separation and purification of the ?-and ?-forms of penta-O-galloyl-D-glucose (PGG) without the need for HPLC. The methods provided herein are useful for separation ?-PGG or ?-PGG from a mixture containing ?-PGG and ?-PGG and other chemicals. The method for separation of ?-PGG from a mixture of ?-PGG and ?-PGG comprises the steps of: adding water to a sample containing 50% or more ?-PGG and 50% or less ?-PGG; mixing the PGG and water to dissolve the PGG; filtering out any undissolved particles; and allowing the filtered solution to stand undisturbed until crystals form.
