Fig. 1 is the process flow diagram of a kind of Memory Optimize Method according to an exemplary embodiment, and this Memory Optimize Method is applied in terminal, and as shown in Figure 1, this Memory Optimize Method comprises the following steps.
In a step 101, receive the internal memory optimization code carrying program identification and internal memory release function, this program identification needs the application program of releasing idling internal memory for identifying, this free memory is that application program takies when front stage operation and do not need the internal memory that takies when running background.
Internal memory release function is the function having the free memory of determining that application program takies and discharge the function of this free memory.
In a step 102, whether running background is switched to from foreground by internal memory optimization code detection application program.
Operate in foreground during application program launching, carry out initialization and can take a large amount of internal memory, enter stable operation after date and forward running background to, now do not need to take a large amount of internal memory, and free memory is still employed program takies, now, releasing idling internal memory can be carried out by internal memory optimization code.
Before the free memory using internal memory optimization code release application program, terminal needs to detect application program and whether is switched to running background from foreground, thus determines whether application program exists free memory.
In step 103, if go out application program by internal memory optimization code detection to be switched to running background from foreground, then by application call internal memory release function, this internal memory release function is used for releasing idling internal memory.
In sum, the Memory Optimize Method that the disclosure provides, by receiving the internal memory optimization code carrying program identification and internal memory release function, this program identification needs the application program of releasing idling internal memory for identifying, this free memory is that application program takies when front stage operation and do not need the internal memory that takies when running background; Whether running background is switched to from foreground by internal memory optimization code detection application program; If go out application program by internal memory optimization code detection to be switched to running background from foreground, then by application call internal memory release function, this internal memory release function is used for releasing idling internal memory, directly can call the internal memory optimization code including internal memory release function, the free memory of application programs discharges, solve and just can trigger memory source recovery when tag memory is not enough, cause terminal to be in the problem of memory source tense situation always, reach the effect of the processing power improving terminal.
Fig. 2 is the process flow diagram of a kind of Memory Optimize Method according to another exemplary embodiment, and this Memory Optimize Method is applied in terminal, and as shown in Figure 2, this Memory Optimize Method comprises the steps.
In step 201, if internal memory release function is in the privately owned function forbidding editing mode, then obtain the specific address of the Public Function of application call, wherein, this Public Function has the authority of invoke memory release function; The specific address of Public Function is shown, the specific address of this Public Function is used to indicate the specific address that calculates internal memory release function and specific address internal memory being discharged function is added in internal memory optimization code, the specific address that the specific address of this internal memory release function equals Public Function adds the relative address of Public Function and internal memory release function, and the relative address of this Public Function and internal memory release function is provided by the symbol table preset.
Internal memory release function is privately owned function in virtual machine source code, be the function having the free memory of determining that application program takies and discharge the function of this free memory, this free memory is that application program takies when front stage operation and do not need the internal memory that takies when running background.Public Function is the function of the authority with invoke memory release function, and specific address is that after function is loaded into application program, system is the memory address that this function distributes.
When application program is run on a virtual machine, the free memory discharged shared by function application programs by virtual machine call internal memory discharges, because virtual machine needs could reclaim internal memory through process for a long time, therefore, the internal memory release function that terminal can directly be called in virtual machine carrys out releasing idling internal memory.If internal memory release function is in the privately owned function forbidding editing mode, that is, internal memory release function is not editable source code, now, in order to call this internal memory release function, terminal needs to obtain the specific address of this internal memory release function when application program is run.
The relative address discharging function due to Public Function and internal memory is fixing, therefore, can be obtained the specific address of internal memory release function by the specific address obtaining Public Function.Therefore, terminal needs the specific address of acquisition Public Function and Public Function and internal memory to discharge the relative address of function.
Wherein, obtain the specific address of the Public Function of application call, comprising:
1) the address reading command carrying the function identification of program identification and Public Function is received;
2) in dynamic link library, the specific address of the Public Function of application call is searched.
When Public Function is employed routine call, system can be this Public Function storage allocation address, and the specific address that this memory address is defined as this Public Function is stored in dynamic link library by terminal.When needing the specific address obtaining this Public Function, terminal directly can read this specific address from dynamic link library.

In step 203, whether running background is switched to from foreground by internal memory optimization code detection application program.
Operate in foreground during application program launching, carry out initialization and can take a large amount of internal memory, enter stable operation after date and forward running background to, now do not need to take a large amount of internal memory, and the internal memory of free time is still employed program takies, now, releasing idling internal memory can be carried out by internal memory optimization code.
Before the free memory using internal memory optimization code release application program, terminal needs to detect application program and whether is switched to running background from foreground, thus determines whether application program exists free memory.When detecting application program and whether being switched to running background from foreground, can by the current state of internal memory optimization Code obtaining application program, if the current state of application program is for hanging up, then determine that application program is at running background, if the current state of application program for running, then determines that application program operates in foreground.
In step 204, if go out application program by internal memory optimization code detection to be switched to running background from foreground, then by application call internal memory release function, this internal memory release function is used for releasing idling internal memory.
If terminal goes out application program by internal memory optimization code detection be switched to running background from foreground, then determine that this application program exists free memory, the free memory that terminal is taken by application call internal memory release function release application program.
Wherein, by application call internal memory release function, comprising:
1) specific address internal memory being discharged function by internal memory optimization code sends to application program;
2) under the instruction of the specific address of internal memory release function, by application call internal memory release function.
Terminal operating internal memory optimization code, the instruction of the specific address carrying this internal memory release function is sent to application program, invoke memory release function under the specific address instruction making application program can discharge function at internal memory, thus the free memory of release shared by application program.
In another embodiment, terminal does not perform step 201, and namely terminal performs step 202-204, and now, internal memory release function is the Public Function obtained after editing the privately owned function being in permission editing mode.That is, internal memory release function is editable Open Source Code, then user can discharge function to internal memory and edits, internal memory is discharged function becomes can directly by the Public Function of application call, now, it is Public Function that internal memory discharges function.
The Public Function obtained after this editor and program identification corresponding to application program can add in internal memory optimization code by user, after terminal enters backstage by internal memory optimization code detection to application program, terminal operating internal memory optimization code, internal memory is discharged function and sends to application program, make application program direct invoke memory release function, the free memory of release shared by application program, and do not need the specific address invoke memory release function by internal memory release function, improve the efficiency of the free memory of release application program.
