The virtual machine heap space capacity that terminal can take at most when this application program got can be run directly is added in releasing order in space and sends to virtual machine.
In step 304, the logical space that the virtual machine heap space capacity that can take at most when virtual machine runs according to this application program and this virtual machine have taken calculates the spatial content of this segment space to be released.
In step 305, virtual machine discharges this segment space according to calculating this spatial content obtained.
Virtual machine can in the logical space taken, the segment space that the virtual machine heap space capacity that can take at most when retaining the operation of this application program is corresponding, and is all discharged in the space of remainder; Or the capacity of the segment space that virtual machine retains can be a bit larger tham the virtual machine heap space capacity that can take at most when this application program is run.
Such as, the logical space capacity that virtual machine has taken as virtual machine heap space is 512M, the virtual machine heap space capacity that application program can take at most is 128M, then virtual machine can retain the 128M in this 512M capacity, and discharged by remaining 384M, or virtual machine is in order to ensure the normal operation of application program, also can retain the 130M in this 512M capacity, and remaining 382M is discharged.
With this terminal for smart mobile phone, this application program is browser is example, the virtual machine heap space taken after virtual machine initialization is 512M, the virtual machine heap space capacity that browser can take at most is 128M, terminal sends to virtual machine the space comprising the virtual machine heap space capacity that browser can take at most and releases order, virtual machine releases order after the capacity that calculates logical space to be released is 384M according to this space, by the 384M release in the 512M virtual machine heap space that takies, being used as can the memory headroom (nativeheap) of viewed device application.After logical space release, browser can open more webpage simultaneously, and such as, browser can open 6 webpages originally simultaneously, after the release of the space of disclosure embodiment, can open maximum 10 webpages simultaneously.
Within step 306, when application program opens new object, whether the quantity that terminal detects the object that this application program has been opened is greater than default amount threshold.
In step 307, if the quantity of object that application program has been opened is greater than default amount threshold, then the terminal data cached deletion of object that this application program is opened the earliest.
Optionally, in scheme shown in disclosure embodiment, the number of objects opened in order to avoid application program too much causes internal memory overflow error, can also by the restricted number of openable for application program object under some preset values, when the quantity of the object opened is greater than this preset value, the object opened at first is closed, and it is data cached.
Such as, take application program as browser be example, the object that this browser is opened is webpage, this browser can be pre-set and can open at most 10 webpages, when the 11st webpage opened by browser, open at first of this browser webpage is closed, and deletes the data cached of its correspondence, to save logical space.
In sum, release shown in disclosure embodiment has taken the method for logical space, by when detecting that application program receives enabled instruction, obtain the virtual machine heap space capacity that can take at most when this application program is run, the virtual machine heap space capacity that can take at most when running according to this application program sends space to this virtual machine and releases order, segment space in virtual machine is discharged logical space that this virtual machine taken, it can be memory headroom to the program application of being employed, thus reaches the effect of the memory headroom that extension application can be applied for.
Fig. 4 is the process flow diagram that a kind of release according to another exemplary embodiment has taken the method for logical space.The method that this release has taken logical space is in the terminal that run application by virtual machine, and such as, this terminal can be smart mobile phone, panel computer and E-book reader etc.As shown in Figure 4, the method that this release has taken logical space can comprise the following steps.
