As mentioned above, google provides an android operating system without a computational mechanism for page-level memory consumption. When the memory occupied by the application program is too high, the situation that which page or pages are opened cannot be located causes the excessive memory occupied by the application program. Furthermore, it is not possible to specifically close or optimize the pages with high memory consumption to mitigate the risk of application crash.
Therefore, the present application provides a flowchart of a method for determining page memory consumption shown in fig. 1 in an exemplary embodiment, where the method may be applied to a terminal device of an android operating system, and the method specifically includes the following steps:
step 110: determining a plurality of target pages to be calculated in the application program.
The target pages can be partial or all pages of the application program.
Step 120: and opening each target page, and calculating the times that each target page can be repeatedly opened before the application program crashes.
After determining a number of target pages to be computed, the following steps need to be performed for each target page based on the processing flow shown in fig. 2:
step A1: initializing the counting value of the target page to be 0;
step A2: opening a target page, simulating the operation behavior of a user in the opened target page, and detecting whether an application program corresponding to the target page triggers the crash caused by memory overflow;
step A3: if not, the count is incremented by one and the previous step A2 is re-executed;
step A4: if so, outputting a count value, and determining the count value as the number of times the target page can be repeatedly opened.
Wherein the simulating the operation behavior of the user comprises: and simulating the user to slide up, down, left and right in the target page.
Step 130: sequencing the target pages according to the number of times that each target page can be repeatedly opened so as to determine the memory consumption of the target pages; the more times of repeatable opening, the less page memory consumption, the less times of repeatable opening, and the more page memory consumption.
In the embodiment, the times that each target page in the application program can be repeatedly opened before the application program crashes are calculated; the more times of repeated opening, the smaller the page memory consumption, the less times of repeated opening and the more page memory consumption; therefore, the memory consumption of each target page can be measured from the side by the index of the number of times of repeated opening. In addition, the target pages are sorted according to the sequence of the times of the repeated opening of each target page. The sorting can be from large to small, or from small to large, and can be flexibly configured according to requirements. In a word, the target pages with high memory consumption can be sequentially positioned according to the sequencing result.
Further, when it is monitored that the memory occupied by the application program exceeds a threshold, the number of times of repeatedly opening corresponding to the opened page of the application program can be obtained.
And then, determining the opened page with the minimum number of times of repeated opening as the opened page with the maximum memory consumption in the application program.
And sequentially closing the opened pages with the most memory consumption in the application program (after the opened pages with the most memory consumption are closed at each time, the closed pages are not opened any more, so that the opened pages with the most memory consumption are automatically changed into the opened pages with the most memory consumption when the memory consumption is many) until the memory occupied by the application program does not exceed a threshold value.
Through the embodiment, when the memory occupied by the application program is too high, the terminal device can quickly locate the opened page (i.e. the opened page with the minimum repeated opening times) which causes the memory occupied by the application program to be too high. And closing the opened page which consumes the most memory in the application program so as to quickly relieve the risk of memory overflow and crash of the application program.
