The existing memory allocation is to give an initial value to an application, wherein the memory value allocated to the application is the initial value when the application runs each time, and when the allocated memory is insufficient to meet the application requirement in the application running process, the application is allocated until the requirement of the application is met, and if the memory exceeds the specified maximum value, the memory overflows.

In the following description, specific details such as specific configurations and components are provided merely to facilitate a thorough understanding of embodiments of the invention. It will therefore be apparent to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.
Referring to fig. 1, an embodiment of the present invention provides a memory allocation method, including:
and step 1, acquiring a target memory value allocated when the application runs at the time and a maximum memory value actually required to be occupied.
And 2, determining the target memory value to be allocated when the application runs next according to the target memory value allocated when the application runs next time, the maximum memory value actually required to be occupied and the first preset value.
The maximum memory value occupied by the application in the current actual need is the required memory generated based on the use behavior of the user in the application use process according to the user. According to the difference of the user operation on the application, the maximum memory value actually occupied by the application in the next running is also different. The first preset value is a maximum memory limit value which can be allocated for the application of the system limit, and for a plurality of applications, the values of the first preset value are the same.
Specifically, the target memory values allocated by the application at the time of the first run and the non-first run are different, and the non-first run includes two cases of the non-first run in which the application is not offloaded and the non-first run in which the application is offloaded. Referring to fig. 2, the determination of the target memory value allocated at the time of the next run specifically includes:
and step 11, judging whether the application is operated for the first time.
And step 12, if so, acquiring a target memory value of which the value allocated during the first running is a second preset value, wherein the second preset value is smaller than the first preset value.
And step 13, if not, judging whether the application is unloaded before the current operation when the application is operated again.
And step 14, if the application is unloaded, acquiring the target memory value allocated when the application runs at the time according to a first preset mode.
In the embodiment of the invention, the initial values allocated to the plurality of applications in the first running are all the second preset values. If the application is not uninstalled, the determination of the target memory value of the application at the time of the current run is obtained by the method described in step 2.
Specifically, referring to fig. 3, step 14 includes:
step 141, obtaining a first target memory value determined according to a target memory value allocated during the last running before the application is uninstalled, a maximum memory value actually required to be occupied and a first preset value, and a total number of detection periods between the moment when the application is uninstalled and the moment when the application is reinstalled, wherein the total number of detection periods is the total number of times of periodically detecting whether the application is reinstalled;
and step 142, obtaining the target memory value allocated when the application runs at the time according to the first target memory value and the total number of detection periods.
After the application is uninstalled, it is periodically checked at preset time intervals (e.g., 3 days) whether the application is reinstalled, and the total number of detection times is accumulated once every time the application is detected once and the application is detected not to be reinstalled. The first target memory value is obtained by the method described in step 2. Preferably, referring to fig. 4, step 142 includes:
step 1421, obtaining a second target memory value according to the first target memory value and the total number of detection periods;
step 1422, determining whether the second target value is greater than or equal to the second preset value;
step 1423, if the second target memory value is greater than or equal to the second preset value, determining the second target memory value as the target memory value allocated when the application runs at the present time;
in step 1424, if the second target memory value is smaller than the second preset value, the second preset value is determined as the target memory value allocated when the application is running at the present time.
Preferably, step 1421 includes:
by the formula:

step 23, if the maximum memory value is greater than the first preset value, determining the first preset value as a target memory value to be allocated when the application runs next time.
The purpose of comparing the maximum memory value actually occupied by the application when running at the time with the first preset value is to prevent the memory allocated to the application from overflowing.
In step 22, the method further implicitly includes that the target memory value allocated when the application runs is smaller than or equal to the first preset value, and when the number of times is the first time, the target memory value allocated when the application runs is a second preset value, and in the previous step, it has been determined that the second preset value is smaller than the first preset value; and after the number of times of the current time is the number of times (for example, the second time), the target memory value allocated when the application is operated at the current time determined according to the previous step is always smaller than or equal to the first preset value.
Preferably, referring to fig. 6, step 22 includes:
step 221, judging whether the target memory value allocated by the application in the current running is greater than or equal to the target memory value;
step 222, if the target memory value allocated to the application in the next run is greater than or equal to the maximum memory value, determining the target memory value allocated to the application in the next run as the target memory value required to be allocated to the application in the next run;
and step 223, if the target memory value allocated to the application in the next running is smaller than the maximum memory value, determining the maximum memory value as the target memory value to be allocated to the application in the next running.
The above method of the present invention will be described in three examples.
Assuming that the initial memory value (second preset value) allocated to the application when running for the first time is 16M, the maximum memory value actually required to be occupied is 34M, and the first preset value is 100M. Assuming that the application is not uninstalled at the second run, at this point 24M is determined to be the target memory value for the application at the second run. If the application is uninstalled in the second running, detecting whether the application is reinstalled or not at the moment of uninstalling the application by taking 3 days as a preset time interval, if the application is reinstalled in the first detection, determining that the target memory value of the application in the first running (total number of times is the second time) after reinstalling is 24M according to the target memory value (16M) allocated in the first running and the maximum memory value (24M) actually required to be occupied by the application, and further obtaining a second target memory value of 12M, wherein the target memory value in the first running after reinstalling is the second preset value (16M) because the second target memory value (12M) is smaller than the second preset value (16M). In this case, the target memory value at the first run after the reinstallation is 16M, regardless of the number of times the application was reinstalled at the time of detection.
Assuming that the initial memory value (first preset value) allocated to the application in the first running is 16M, the maximum memory value actually required to be occupied is 12M, and the second preset value is 100M. Assuming that the application is not uninstalled at the second run, then 16M is determined as the target run value for the application at the second run; if the application is unloaded in the second running, detecting whether the application is reinstalled or not at the moment of unloading the application by taking 3 days as a preset time interval, if the application is reinstalled in the first detection, determining that the target memory value of the application in the first running (total times are the second) after reinstallation is 24M according to the target memory value (16M) allocated in the first running and the maximum memory value (24M) actually required to be occupied by the application, and further obtaining a second target memory value of 12M, wherein the target memory value in the first running after reinstallation is the second preset value (16M) because the second target memory value (12M) is smaller than the second preset value (16M); in this case, the target memory value at the first run after the reinstallation is 16M, regardless of the number of times the application was reinstalled at the time of detection.
Assuming that the initial memory value (first preset value) allocated to the application in the first running is 16M, the maximum memory value actually required to be occupied is 48M, and the second preset value is 100M. Assuming that the application is not uninstalled at the second run, 48M is determined as the target run value for the application at the second run; if the application is uninstalled in the second running, detecting whether the application is reinstalled or not at the moment of uninstalling the application by taking 3 days as a preset time interval, if the application is reinstalled in the first detection, determining that the target memory value of the application in the first running (total number of times is the second time) after reinstalling is 48M according to the target memory value (48M) allocated in the first running and the maximum memory value (48M) actually required to be occupied by the application, and further obtaining a second target memory value of 24M, wherein the target memory value in the first running after reinstalling is the second target memory value (24M) because the second target memory value (24M) is larger than the second preset value (16M). If it is determined that the application is reinstalled at the time of the second detection, it is affirmative that the above-described step can determine that the target memory value at the time of the first run after the application is reinstalled in this state is 16M, and in this case, the target memory value at the time of the first run after the application is reinstalled is 16M regardless of whether the application is determined to be reinstalled at any one time after the second detection.
