the first part is three basic processes which are automatically created when a browser is opened: the Browser process, the GPU process and the Zygote process, wherein the memory occupied by the three processes is maintained at a stable value after the Browser is opened. As for the creation processes and functions of these three basic processes, reference may be made to the related art, which is not described herein again.

The second part is that when a webpage is opened in a Browser, every time a webpage is opened, the Browser process creates a corresponding Render process, and the Render process is used for webpage rendering and can realize functions such as webpage resource requests. Because the complexity of each web page is different, the size of the memory used by the Render process corresponding to each web page is different, for example, some Render processes corresponding to web pages may use 50MB of memory, and some Render processes corresponding to web pages may use more than 200 MB of memory.

Based on the above, in this step 201, when N webpages are opened on a specified browser, there are three basic processes in the browser: a Browser process, a GPU process, a Zygote process and N Render processes corresponding to the N webpages.

Step 202, adjusting the preset memory threshold M corresponding to each Render process that has been set _R Is (M) _T –(M _B +M _G +M _Z ))/N。

In the embodiment of the present application, M is as defined above _T For specifying a preset total memory threshold value in the browser, the total memory threshold value is used for limiting the browserIf the total memory used by the browser exceeds the total memory threshold, the browser may be triggered to be processed, for example, a webpage opened by the browser is closed to clear the memory.

Further, M is as defined above _B Memory threshold, M, preset for Browser progress _G Memory threshold, M, preset for GPU Process _Z A memory threshold value preset for the zygate process. Wherein the Browser process, the GPU process and the Zygote process are processes which need to be executed for running a specified Browser.

In specific implementation, if only one webpage 1 is opened in a Browser, when the webpage 1 is opened, a Browser process creates a Render1 process for the webpage 1, and a threshold value M is preset for a memory corresponding to the Render1 process _R1 According to the above steps 201 to 202, the preset memory threshold M corresponding to the Render1 process can be obtained _R1 Is (M) _T –(M _B +M _G +M _Z ) As shown in fig. 5, the total memory threshold preset in the designated browser may be divided with reference to fig. 5.

Illustratively, if two web pages are open in the browser: and the webpage 1 and the webpage 2 are respectively provided with a Render1 process by the Browser process when the webpage 1 is opened, and a Render2 process by the Browser process when the webpage 2 is opened. Presetting a threshold M aiming at a memory corresponding to a Render1 process _R1 And a memory preset threshold M corresponding to the Render2 process _R2 According to the above steps 201 to 202, the memory preset threshold M can be obtained _R1 And a memory preset threshold M _R2 Are the same value of M _R1 ＝M _R2 ＝(M _T –(M _B +M _G +M _Z ) 2), as shown in fig. 6, the total memory threshold preset in the designated browser may be divided with reference to fig. 6, and the remaining memory threshold obtained by subtracting the memory thresholds corresponding to the three basic processes from the total memory threshold is equally divided into two parts, which are respectively allocated to M _R1 And M _R2 。

Illustratively, if i web pages are open in the browser: web pages 1 to i, then in the Browser, the Browser process will be web page 1 to web page ii, creating i Render processes which are Render1 process to Render process respectively. Presetting a threshold M aiming at a memory corresponding to a Render1 process _R1 Presetting threshold M to memory corresponding to Render i process _Ri According to the above steps 201 to 202, the memory preset threshold M can be obtained _R1 ～M _Ri A value of (i), i.e. M _R1 ＝M _R2 ＝…＝M _Ri ＝(M _T –(M _B +M _G +M _Z ) I), as shown in fig. 7, the total memory threshold preset in the designated browser may be divided with reference to fig. 7, and the remaining memory threshold obtained by subtracting the memory thresholds corresponding to the three basic processes from the total memory threshold is equally divided into i parts, which are respectively allocated to M _R1 ～M _Ri 。

Thus, the flow shown in fig. 2 is completed.

Through the embodiment shown in fig. 2, the preset memory threshold M corresponding to the Render process for rendering the web page corresponding to the web page can be dynamically adjusted according to the number of the web pages opened in the browser _R For example, when N webpages are opened on a designated browser, the preset memory threshold M corresponding to each Render process that has been set is adjusted _R Is (M) _T –(M _B +M _G +M _Z ) N), thereby realizing more refined management on the memory of the browser and avoiding the browser from crashing.

How to dynamically adjust the preset memory threshold M corresponding to the Render process determined in the above steps 201 to 202 is as follows _R A description will be given. Referring to fig. 3, fig. 3 is a diagram illustrating a preset memory threshold M corresponding to a dynamic adjustment Render process according to an embodiment of the present disclosure _R Is shown in the method flow chart. As an embodiment, the flows shown in fig. 3 and 2 may be applied to the display device as described above.

As shown in fig. 3, the process may include the following steps:

step 301, when any webpage is browsed in foreground, if it is detected that a memory occupied by a Render process corresponding to the currently browsed webpage is greater than or equal to a preset memory threshold M corresponding to the Render process _R 。

As one example, render proceeds corresponding to a currently viewed web pageThe memory occupied by the program can be divided into two parts, one part is the memory actually used by the Render process, and the other part is a preset memory cache region M distributed for the Render process after the Render process is established _PAD Presetting a memory buffer area M _PAD The method has the function of providing a buffer for the fact that the memory actually used by the Render process is increased, and avoiding the phenomenon that the Render process corresponding to the webpage is blocked due to the fact that the memory actually used is suddenly increased.

It should be noted that, for a Render process, a preset memory buffer M may be allocated to the Render process _PAD As shown in fig. 9, a plurality of predetermined memory buffers M may also be allocated to the Render process _PAD As shown in fig. 10, three predetermined memory buffers M are allocated to the Render process in fig. 10 _PAD . Particularly, how many preset memory cache regions M are allocated to the Render process _PAD The setting of different browsers can be used, and the application is not limited to this.

Step 302, judging whether other web pages exist in the background of the specified browser, if not, executing step 303, otherwise, executing step 304.

Step 303, releasing the network resource in the idle state in the specified browser.

As an embodiment, if there are no other web pages in the background of the specified browser, it indicates that only one web page is opened in the specified browser currently, and it is assumed that the memory actually used by a Render process (denoted as Render1 process) in the web page is M _R11 And is allocated a predetermined memory buffer M _PAD When M is present _R11 And M _PAD The value obtained after the addition is larger than or equal to a preset memory threshold M corresponding to the Render1 process _R1 At this time, the memory M actually used by the Render1 process is indicated _R11 Has reached the preset memory threshold M _R1 As shown in FIG. 8, M is shown from top to bottom in FIG. 8 _R11 And M _PAD Is less than M after addition _R1 、M _R11 And M _PAD After addition equals M _R1 And M _R11 、M _PAD Added to be greater than M _R1 Schematic representation of (a).

Thus, canReleasing network resources in an idle state existing in cache and shared memory in the browser, and adjusting the network resources in the idle state to a preset memory threshold M corresponding to a Render1 process _R1 In (1).

Further, if a threshold M is preset for the memory corresponding to the Render1 process _R1 After adjustment, M _R11 And M _PAD Added to obtain a value greater than or equal to M _R1 If the current webpage is a webpage with a complex webpage, the current webpage can be used without redundant memory in the current system environment. Therefore, a set out of memory (out of memory) function can be triggered, the Browser process is notified to close the Render process, all the memory occupied by the Render process is released, and a prompt message of the OOM can be popped up to prompt the user that the webpage is to be closed due to the memory overflow.

Step 304, adjusting the memory occupied in the Render process corresponding to other web pages to the preset memory threshold value M corresponding to the Render process of the web page browsed in the foreground _R In (1).

As an embodiment, if there are other web pages in the background of the specified browser, it indicates that there are at least two web pages in the specified browser.

For example, assume that two web pages are currently present in a given browser: the method comprises the following steps that a webpage 1 and a webpage 2 are provided, the webpage 1 is in a background of a browser, the webpage 2 is a webpage browsed at the foreground currently, a Render process corresponding to the webpage 1 is a Render1 process, a Render process corresponding to the webpage 2 is a Render2 process, and an internal memory actually used by the Render2 process is M _R21 And is allocated a predetermined memory buffer M _PAD When M is present _R21 And M _PAD The value obtained after the addition is larger than or equal to a preset memory threshold M corresponding to the Render2 process _R2 The memory occupied by Render1 process can be adjusted to M _R2 In (1).

As an embodiment, the memory occupied by Render1 process is adjusted to M _R2 Before, it may be determined whether the memory actually occupied by the Render1 process is smaller than the memory pre-fetch corresponding to the Render1 processSet threshold value M _R1 . Here, the memory actually occupied by the Render1 process includes the memory M actually used by the Render1 process _R11 And at least one preset memory buffer area M distributed _PAD And M is _R1 ＝M _R2 ＝(M _T –(M _B +M _G +M _Z ))/2。

Optionally, if it is determined that the memory actually occupied by the Render1 process is smaller than the preset memory threshold M corresponding to the Render1 process _R1 And at least M preset memory cache regions M are distributed in the Render1 process _PAD And M is larger than 2, then (M-1) M in the Render1 process can be selected _PAD Adjusting to a memory preset threshold M corresponding to a Render2 process _R2 At this time, a memory preset threshold M corresponding to the Render1 process is set _R1 Will be reduced by (M-1) M _PAD 。

Optionally, if it is determined that the memory actually occupied by the Render1 process is greater than or equal to the preset memory threshold M corresponding to the Render1 process _R1 And/or only one preset memory buffer zone M is allocated in the Render1 process _PAD Then, the configured Discard function in the browser may be triggered, and all the memories (including the memory M) occupied by the Render1 process are released _R11 And M allocated _PAD ) Meanwhile, key information of the Render1 process is reserved in the Browser process, so that the webpage 1 corresponding to the Render1 process can be quickly entered again. After the webpage 1 is removed, only the webpage 2 remains in the browser at this time, and the memory preset threshold value M corresponding to the Render2 process of the webpage 2 _R2 The M being _R2 ＝M _T –(M _B +M _G +M _Z ) Next, the memory occupied by the web page 2 may be managed according to step 303.

Illustratively, based on the above, when two webpages exist in the browser, the preset memory threshold M corresponding to the Render process corresponding to the webpages is dynamically adjusted _R In the exemplary process, assume that i webpages (including webpages 1 to i) are opened in the browser at the same time, wherein a preset memory threshold M corresponding to a Render1 process is set _R1 Presetting threshold M to memory corresponding to render process _Ri Comprises the following steps: m is a group of _R1 ＝M _R2 ＝…＝M _Ri ＝(M _T –(M _B +M _G +M _Z ) I), then the preset memory threshold M can be dynamically adjusted when two web pages exist according to the above _R The process of (2):

if the current browsed webpage in foreground is webpage i, the practically used memory M occupied by Render i process corresponding to webpage i _Ri1 Plus M _PAD The preset balance threshold value M of the memory of the Render i process is larger than or equal to _Ri Then, the memory occupied by Render1 process to Render (i-1) process can be adjusted to M in sequence _R2 In (1).

As an embodiment, for any Render process from Render1 process to Render (i-1) process, the Render process (denoted as Render j process, 1) may be determined first<＝j<= i-1) whether the memory actually occupied is smaller than a preset memory threshold M corresponding to the Render j process or not _Rj . Here, the memory actually occupied by the Render j process includes the memory M actually used by the Render j process _Rj1 And at least one allocated preset memory buffer area M _PAD 。

Optionally, if it is determined that the memory actually occupied by the Render j process is smaller than the preset memory threshold M corresponding to the Render j process _Rj And at least M preset memory buffer areas M are distributed in the Render j process _PAD And M is greater than 2, then (M-1) M in Render j process can be set _PAD Adjusting to a memory preset threshold M corresponding to Render i process _Ri At this time, a memory preset threshold value M corresponding to the render process is set _Rj Will be reduced by (M-1) M _PAD 。

Optionally, if it is determined that the memory actually occupied by the Render j process is greater than or equal to the preset memory threshold M corresponding to the Render j process _Rj And/or only one default memory buffer M is allocated in Render j _PAD Then, the configured Discard function in the browser may be triggered, and all the memories (including the memory M) occupied by the Render j process are released _Rj1 And M allocated _PAD ) And meanwhile, key information of the Render j process is reserved in the Browser process, so that the webpage j corresponding to the Render j process can be quickly accessed again. After removing page j, only (i-1) pages remain in the browser at this time, which may beReadjusting the preset threshold of the memory corresponding to the (i-1) web pages to be (M) _T –(M _B +M _G +M _Z ))/(i-1)。

Further, if the memory occupied by the Render process corresponding to the currently browsed webpage is still greater than or equal to the preset threshold (M) of the newly adjusted memory corresponding to the Render process _T –(M _B +M _G +M _Z ) And (i-1), continuously acquiring the memory occupied by the Render process corresponding to other web pages in the background in the browser according to the steps to adjust.

The flow shown in fig. 3 is completed. Through the process shown in fig. 3, the preset memory threshold M corresponding to the Render process may be dynamically determined in fig. 2 _R On the basis, in the using process of the webpage, presetting a threshold value M for the memory determined by the Render process of the webpage _R The dynamic adjustment is carried out again, and the memory is preset with a threshold value M _R 。

It should be noted that, in step 301, if it is detected that the memory occupied by the Render process corresponding to the currently browsed webpage is smaller than the preset memory threshold M corresponding to the Render process _R Then, it is not necessary to preset a threshold M for the memory corresponding to the Render process _R And (6) adjusting.
