Abstract
The invention discloses a resource optimization method of a lightweight browser based on an Android system, which is used for reducing the time for loading kernel resources and the space occupied by the kernel resources by optimizing the access mode of the kernel resources.
Description
Technical Field
The invention relates to the technical field of browsers, in particular to a resource optimization method of a lightweight browser based on an Android system.
Background
At present, with the popularization of Android smart televisions, the requirements on the application performance and the user experience of the Android televisions are higher and higher, and as the first application which enters after the Android system is started, the performance of the Android desktop management application directly influences the experience of the whole system.
In order to solve the problems, Android television desktop management application developers use a lightweight browser to develop television desktop management applications. The resources of a typical lightweight browser require more space and time to access. Under the background that the application of the television is more and the functions are more and more abundant nowadays, under the condition that the functions are not influenced, the resource occupation of all the applications is reduced, and the method has a decisive role in improving the Android television performance. Therefore, optimizing the resources of the lightweight browser is the most important point in optimizing the performance of the Android television.
The existing problem is that the resources of the common lightweight browser need more space and time to access, because a common resource access mode is adopted. In a general resource access method, all resources are written first, and then the written resources are read, so that the operation of writing the resources consumes much space and time.
In order to provide better user experience for users and enable a light browser to run faster and occupy less space on Android, the method and the device optimize kernel resources by changing the access mode of the kernel resources.

In the invention, the core component of the browser is a browser kernel, and the browser kernel is a rendering engine adopted by the browser. In the invention, the browser rendering engine also becomes a browser kernel, which is called the kernel for short. The kernel is responsible for interpreting the syntax of the web page and displaying the web page.
The resource related to the invention is a kernel resource, and the kernel resource is a resource which can be used by the kernel to display the webpage content after explaining the webpage grammar, for example, font resources can be used to display the characters on the webpage.
The lightweight browser is a browser occupying a small amount of resources during operation, and the kernel of the Android native browser occupies more resources during operation. Compared with the kernel of the Android native browser, the kernel of the lightweight browser occupies less system resources.
The kernel resources of the lightweight browser are typically stored in the Android system by writing. And calling the resources written into the Android system when the kernel explains the webpage and displays the webpage.
The invention realizes the purpose through the following technical scheme:
a resource optimization method of a lightweight browser based on an Android system comprises the following steps:
step s1, defining a SYSTEM PATH SYSTEM _ PATH and a write PATH control _ PATH corresponding to the kernel resource in the kernel;
step s2, starting the desktop management application, and initializing the browser kernel;
step s3, step s2 is executed to start the initialization of the browser kernel in the process, the SYSTEM PATH is scanned correspondingly according to the SYSTEM _ PATH defined in step s1, if the SYSTEM resources exist, step s4 is executed, and if the SYSTEM resources do not exist, step s6 is executed;
step s4, according to the scanning result of step s3, determining whether all the target resources exist, if yes, entering step s5, otherwise, entering step s 6;
step s5, the resource in the SYSTEM _ PATH is used as the corresponding kernel resource, and the kernel resource completes the storage;
step s6, creating a resource write directory CONTENT _ PATH, and writing the resource write directory CONTENT _ PATH into the kernel resource;
step s7, storing the required kernel resource in the CONTENT _ PATH, and finishing the storage of the kernel resource at this time;
step s8, creating a resource write directory CONTENT _ PATH, and writing the missing kernel resource, where part of the kernel resource is stored in SYSTEM _ PATH and CONTENT _ PATH;
step s9, the kernel resource storage is finished, and the kernel starts to read the kernel resource;
step s10, scanning whether the SYSTEM _ PATH has the target resource, if yes, entering step s12, and if not, entering step s 11;
step s11, scanning and reading the target resource in the CONTENT _ PATH;
and step s12, the kernel renders the webpage by using the kernel resource, and finally displays the desktop management application.
In step s1, the font resource path is defined as: "/system/fonts", or multiple paths for multiple resources, depending on the particular path definition of the resources in the system.
In a further embodiment, in step s1, the modified kernel reads the system PATH resources first, and the modified kernel does not find the read write PATH CONTENT _ PATH.
The invention has the beneficial effects that:
according to the resource optimization method of the lightweight browser based on the Android system, the access mode of the kernel resource is optimized, so that the time for loading the kernel resource by the lightweight browser and the space occupied by the kernel resource are reduced; the method comprises the following steps: 1. the system resources stored in the Android system are used as kernel resources of the lightweight browser; 2. when the android system runs, the lightweight browser firstly scans a system resource path; 3. when the lightweight browser runs in the android system, scanning a target resource file under a system resource path, and not writing corresponding resources into a system disk; and changing the reading of the lightweight browser on the kernel resource on the android system, wherein the reading comprises the following steps: 1. when reading the kernel resource, scanning a corresponding system resource path; 2. the system resource path is directly read when scanned to the target, and is not scanned under the system resource path, and then the system resource path is scanned and written into the resource path for reading; 3. and scanning the target resource by the kernel under the system path, and rendering the page by taking the read system resource as the kernel resource.
