Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
In the description of the present invention, the meaning of a plurality of means is one or more, the meaning of a plurality of means is two or more, and more than, less than, more than, etc. are understood as excluding the present number, and more than, less than, etc. are understood as including the present number. If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.
Referring to fig. 1, a method of an embodiment of the present invention includes: a preloading optimization step, namely judging whether the system is not a first-time flashing, adjusting a loading strategy flow of the Zygote according to a first judgment result, and starting system service after the Zygote loads preloading resources; a WIFI enabling optimization step, namely before the system is powered off, closing the WIFI function, and after the system service is started, starting the WIFI function; and UI loading optimization, namely judging whether the key lock and/or the pull-down status bar exist or not according to the service characteristics of the product, and cutting the system UI loading of the key lock and/or the pull-down status bar according to a second judgment result.
The optimization method of the preloading optimization step is to reduce the loading amount and start the SystemServer in advance by adjusting the loading strategy of Zygote. Referring to fig. 2, it can be seen that the system service (SystemServer) must wait for the zygate to execute all the events in sequence before starting. In the embodiment of the invention, referring to fig. 3, except for the first time of system startup, the system service to be started is started only after Zygote finishes preloading resources, and the system service can be prepared in advance and enter into starting other services earlier. For non-essential preloaded items, include: the pre-loading class, the pre-loading application program hardware abstraction layer, the pre-loading display card drive and the pre-loading shader library are executed in parallel through multithreading and system service, so that the starting speed is accelerated, and the optimization effect is about 3s through testing.
In the embodiment of the invention, the WIFI enablement is optimized during startup. When an Android system running on the equipment receives a shutdown instruction, judging whether wifi is turned on or not; if the WIFI is in an open state, in the SHUTDOWN process, the wireless enabled is set to false firstly by monitoring the active _ SHUTDOWN broadcast, and the processes such as a hardware data extraction layer, a WIFI Driver, a suppernant, a configurable chip and the like related to the WIFI cannot be loaded when the next startup is carried out, and the loading is carried out when the load is low, so that the startup speed is accelerated. After the system service is started, namely after the ACTION _ LOCK is monitored, the WIFI enabled is set to true, at the moment, the flow related to the WIFI is delayed and loaded, and a user can immediately see that the WIFI is connected when entering a main interface. Through testing, the starting speed can be improved by about 2.5s by WIFI enabling optimization.
Referring to fig. 2, in an original booting process of an Android system, all system UIs are loaded into a desktop only after all system UIs are completely loaded. In the embodiment of the present invention, whether to load the key lock and pull down the menu bar is determined according to the product service characteristics, for example: the television box product does not need a screen locking function and a pull-down status bar, and the loading of the key lock and the pull-down menu bar is skipped in the loading process of the system UI, so that the time-consuming loading process of the key lock and the pull-down menu bar is omitted. If the product needs the key lock or the pull-down menu bar but has no strong real-time requirement, the loading of the key lock or the pull-down menu bar is delayed until the desktop is started, and then the product is loaded, so that the starting speed can be increased, and the starting speed can be increased by about 5s through testing.
The apparatus of the embodiment of the present invention, referring to fig. 4, includes: the preloading optimization module 100 is configured to determine whether the system is not a first-time flashing, adjust a loading policy flow of the zygate according to a first determination result, and start a system service after the zygate loads a preloading resource; the WIFI enabling optimization module 200 is used for closing the WIFI function before the system is powered off and then starting the WIFI function after the system service is started; and the UI loading optimization module 300 is configured to determine whether the key lock and/or the pull-down status bar exist according to the product service characteristics, and trim the system UI loading of the key lock and/or the pull-down status bar according to a second determination result.
According to the embodiment of the invention, the optimization effect on various Android systems is about 8-10.5 s, referring to fig. 5.
