[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] In the description of the present invention, "several" means one or more, "more" means two or more, "greater than", "less than", "exceed" etc. are understood as not including the number itself, and "above", "below", "within" etc. are understood as including the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0028] Reference Figure 1 The method of the embodiment of the present invention includes: a preloading optimization step, judging whether the system is not flashed for the first time, adjusting the loading strategy process of Zygote according to the first judgment result, and starting the system service after Zygote loads the preloading resources; a WIFI enabling optimization step, turning off the WIFI function before the system is shut down, and turning on the WIFI function after the system service is started; a UI loading optimization step, judging whether there is a key lock and / or a drop-down status bar through product business characteristics, and cutting out the system UI loading of the key lock and / or the drop-down status bar according to the second judgment result.

[0029] The optimization method of the pre-loading optimization step is to adjust the loading strategy of Zygote, reduce the loading amount, and start SystemServer in advance. Figure 2 It can be seen that the system service (SystemServer) must wait for Zygote to execute all the tasks in sequence before starting. In the embodiment of the present invention, refer to Figure 3 , except for the first system startup, the system service only needs to be started after Zygote completes preloading resources, so that the system service can prepare in advance and start other services earlier. For non-essential preloaded items, including: preloading classes, preloading application hardware abstraction layer, preloading graphics card driver and preloading shader library, they are executed in parallel with system services through multithreading, thereby accelerating the startup speed. Through testing, the optimization effect is about 3s.

[0030] In an embodiment of the present invention, the WIFI activation is also optimized at startup. When the Android system running on the device receives a shutdown command, it determines whether the WIFI is turned on; if the WIFI is turned on, during the shutdown process, by monitoring the ACTION_SHUTDOWN broadcast, wifiEnabled is first set to false. The next time the machine is started, the WIFI-related hardware data extraction layer, WIFI driver, Driver, Supplicant, ConfigureChip and other processes will not be loaded. They will be loaded when the load is low, thereby speeding up the startup speed. After the system service is started, that is, after monitoring ACTION_LOCK, wifiEnabled is set to true. At this time, the loading of WIFI-related processes is delayed. When the user enters the main interface, he can immediately see that the wifi is connected. Through testing, WIFI activation optimization can increase the startup speed by about 2.5s.

[0031] Reference Figure 2 In the original boot process of the Android system, all system UIs must be fully loaded before they can be loaded into the desktop. In an embodiment of the present invention, whether the key lock and the drop-down menu bar need to be loaded is determined based on the product business characteristics. For example, if the TV box product does not require a lock screen function and a drop-down status bar, the loading of the key lock and the drop-down menu bar is skipped during the system UI loading process, thereby omitting the time-consuming key lock and drop-down menu bar loading process. If the product requires a key lock or a drop-down menu bar, but the real-time requirements are not strong, the loading of the key lock or the drop-down menu bar is delayed until the desktop startup is completed, thereby speeding up the boot speed. Through testing, the boot speed can be accelerated by about 5s.

[0032] The device of the embodiment of the present invention, referring to Figure 4 , including: a preloading optimization module 100, used to determine whether the system is not flashed for the first time, and adjust the loading strategy process of Zygote according to the first judgment result. After Zygote loads the preloading resources, it starts the system service; a WIFI activation optimization module 200, used to turn off the WIFI function before the system is shut down, and turn on the WIFI function after the system service is started; a UI loading optimization module 300, used to determine whether there is a key lock and / or a drop-down status bar through product business characteristics, and according to the second judgment result, cut off the system UI loading of the key lock and / or the drop-down status bar.

[0033] The optimization effect of the embodiments of the present invention on various Android systems can be seen in Figure 5 The optimization method of the present invention has an optimization effect of about 8 to 10.5 seconds.
