All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to improve the calculation efficiency of the page frame dropping information, the embodiment of the invention provides a method and a device for determining the page frame dropping information of an application program and electronic equipment.
Referring to fig. 1, fig. 1 is a schematic flowchart of a method for determining page frame dropping information of an application according to an embodiment of the present invention, which specifically includes the following steps:
The page drawing frequency of the terminal equipment display is controlled by the operating system display card, the starting of one-frame page drawing is represented every time the operating system display card generates a vertical synchronization signal, and the frequency of the vertical synchronization signal generated by the operating system display card is the actual page drawing frequency of the display, namely the actual refreshing frequency of the current page of the application program.
Specifically, the page rendering (refreshing) process of the display is not that the whole page is changed simultaneously, but that a single pixel point is rendered and refreshed line by line, so that only when the refreshing frequency reaches a certain degree, human eyes cannot perceive the page refreshing process, that is, when the refreshing frequency reaches a certain degree, the page is smooth and continuous for human eyes, generally speaking, the theoretical refreshing frequency can be set to be 60Hz, and when the refreshing frequency is not lower than the theoretical refreshing frequency, the page seen by human eyes is smooth.
And 103, calculating frame dropping information of the application program in each preset time period based on the frame dropping number, wherein the frame dropping information represents the frequency of frame dropping of the current page of the application program.
In this step, the frame dropping information may be calculated in various ways, for example: the ratio of the dropped frame number to the first theoretical refresh frame number may be used as the dropped frame information of the application program in each preset time period; or the ratio of the dropped frame number to the preset time period can be used as the dropped frame information of the application program in each preset time period; the ratio of the dropped frame number to the actual refresh frame number of the current page of the application program in each preset time period may also be used as dropped frame information of the application program in each preset time period, and the like, where a specific manner for calculating the dropped frame information is not limited.
In the embodiment of the invention, the frame dropping number of the current page of the application program in each preset time period can be calculated according to the acquisition time of the vertical synchronization signal, so that the frame dropping information representing the frequency of the frame dropping of the current page of the application program is obtained.
Referring to fig. 2, fig. 2 is another schematic flow chart of a method for determining page frame dropping information of an application according to an embodiment of the present invention, which specifically includes the following steps:
And step 204, subtracting 1 from the second theoretical refresh frame number to obtain a second difference between the second theoretical refresh frame number and the actual refresh frame number of the current page of the application program in the acquisition time interval.
And the first theoretical refresh frame number is the theoretical refresh frame number of the page in a preset time period.
And step 206, based on the frame dropping number, calculating the frame dropping information of the application program in each preset time period, wherein the frame dropping information represents the frequency of frame dropping of the current page of the application program.
In this step, the frame dropping information may be calculated in various ways, for example: the ratio of the dropped frame number to the first theoretical refresh frame number may be used as the dropped frame information of the application program in each preset time period; or the ratio of the dropped frame number to the preset time period can be used as the dropped frame information of the application program in each preset time period; the ratio of the dropped frame number to the actual refresh frame number of the current page of the application program in each preset time period may also be used as dropped frame information of the application program in each preset time period, and the like, where a specific manner for calculating the dropped frame information is not limited.
For ease of understanding, the contents of the above steps 201-206 are explained in detail below by way of specific examples:
assuming that page frame dropping information of the application a installed in the client device is to be determined, in step 201, a vertical synchronization signal generated by an operating system of the client device can be monitored and acquired in real time, in steps 202-203, an acquisition time of each acquisition of the vertical synchronization signal is recorded, in each time period of 1000ms, an acquisition time interval of two consecutive acquisition of the vertical synchronization signal is calculated, assuming that 1000ms is a time period, and then a product of the acquisition time interval and a theoretical refresh frequency is determined as a second theoretical refresh frame number in the acquisition time interval, for example, a time when the vertical synchronization signal is received for the first time is t1 ms, a time when the vertical synchronization signal is received for the second time is t2 ms, the acquisition time interval is 50ms, and the second theoretical refresh frame number in the acquisition time interval is 50ms × 60Hz — 3, in step 204, obtaining a second difference between a second theoretical refresh frame number and an actual refresh frame number of the current page of the application program in the obtaining time interval, where the second difference is 3-1 to 2, and so on, and thus a second difference corresponding to the obtaining time interval of the vertical synchronization signal obtained continuously any two times in the same time period can be obtained, and in step 205, summing all the second differences in the same preset time period, so as to obtain a first difference between the first theoretical refresh frame number and the actual refresh frame number of the current page of the application program in the preset time period, which is used as a dropped frame number of the current page of the application program in the preset time period; finally, in step 206, the frame dropping information of the current page of the application a in each preset time period can be determined by any one of the frame dropping information determination methods listed in step 206.
And step 207, when each preset time period is finished, respectively sending the frame dropping information and the identification information of the current page in the preset time period to the server side equipment in communication connection with the client side equipment.
At present, aiming at the method that research and development personnel need to start the developer permission in the terminal device operating system, so that the frame dropping frequency of the current page is manually analyzed, due to the limited personnel, high manual analysis cost and the like, only the page frame dropping information of the application program on the individual testing client device with the developer permission started can be obtained, and the page frame dropping information of the application program on a large batch of or all testing client devices cannot be obtained.
During the page optimization design, in order to quickly and accurately locate a page to be optimized, page frame dropping information of an application program on a large number of client devices for testing can be acquired, and the acquired page frame dropping information is divided into a plurality of levels according to a preset frame dropping information threshold, for example, the page frame dropping information is divided into three levels, namely a high frame dropping rate, a medium frame dropping rate and a low frame dropping rate, specifically, more than 30% of the frame dropping information can be divided into high frame dropping rate information, more than 10% and less than 30% of the frame dropping information can be divided into medium frame dropping rate information, and less than 10% of the frame dropping information can be divided into low frame dropping rate information. For the current page, when the number of the client devices with high frame dropping rate information exceeds a certain preset number or a certain preset proportion, the current page may be determined as a page to be optimized. In the embodiment of the present invention, after the frame dropping information of the page is automatically obtained, the client device may further send the obtained frame dropping information and the identification information of the current page to the server device, so that the server device obtains the page frame dropping information when the application program runs on a large number of or all client devices, and then divides the obtained page frame dropping information into a plurality of levels according to a preset frame dropping information threshold, for example, the page frame dropping information into three levels, i.e., a high frame dropping rate, a medium frame dropping rate and a low frame dropping rate, specifically, more than 30% of the frame dropping information may be divided into high frame dropping rate information, more than 10% and less than 30% of the frame dropping information may be divided into medium frame dropping rate information, and less than 10% of the frame dropping information may be divided into low frame dropping rate information. For the current page, when the number of the client devices with high frame dropping rate information exceeds a certain preset number or a certain preset proportion, the current page may be determined as a page to be optimized.
Further, different page data may be presented in the same page of the application program at different times, for example, at a previous time, a video playing area and a comment area may be displayed in the page, but at a next time, the user may maximize the video playing area, and at this moment, only one video playing area is displayed in the page.
In the embodiment shown in fig. 2, the frame dropping number of the current page of the application program in each preset time period can be calculated according to the acquisition time of the vertical synchronization signal, and then frame dropping information representing the frequency of frame dropping of the current page of the application program is obtained. Meanwhile, after the frame dropping information of the page is automatically obtained, the obtained frame dropping information and the identification information of the current page are sent to the server side equipment, and a reference basis is provided for quickly positioning the page to be optimized.
Referring to fig. 3, fig. 3 is a schematic flowchart of another method for determining information of dropping frames of an application page according to an embodiment of the present invention, which specifically includes the following steps:

And 304, calculating frame dropping information of the application program in each preset time period based on the frame dropping number, wherein the frame dropping information represents the frequency of frame dropping of the current page of the application program.

The contents of step 304 and step 305 are the same as the contents of step 206 and step 207, respectively, and are not described herein again.
