Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The present inventor studies discovery, and application especially has in the application of user's interface display, and internal memory is greatly shared by the color data of the object picture applied; And the display of various user interface controls (as button, text box, picture box, list box, grid frame etc.) all relies on object picture in terminal device system, often each user control has multiple object picture, object picture is larger, and the internal memory shared by the color data of object picture is also larger; If the color data therefore by the object picture to application processes, make the object picture (when switching to background application as applied) when not showing applied, release cleaning is carried out to internal memory shared by the color data of object picture, when the image object applied shows (when switching to foreground application as applied), again the color data of object picture is recovered, then the running memory of terminal device can be made greatly to be optimized.
The process flow diagram of the Memory Optimize Method that Fig. 1 provides for the embodiment of the present invention, the method mainly describe how to carry out object picture color data shared by internal memory release cleaning, the method can be applicable in terminal device, as mobile phone, panel computer, notebook computers etc. can carry out the terminal device of content display, and with reference to Fig. 1, the method can comprise:
If step S100 detects that application switches to background application, determine that described application need discharge the object picture of color data;
Optionally, the opportunity of the internal memory shared by color data of the object picture of release application, can for application switch to background application time, as dispatch at task manager one be applied as background application time, the embodiment of the present invention can trigger and discharge the internal memory shared by the color data of the object picture of this application;
Optionally, the object picture that determined application need discharge color data can be all object pictures of this application, also can be some object pictures of this application of setting.
Step S110, store the color data of described object picture;
Optionally, before the release cleaning of the internal memory of the embodiment of the present invention shared by the color data of carrying out the object picture applied, display for ease of the object picture of this application follow-up needs, the color data of the object picture of this application can first store by the embodiment of the present invention, to use during the color data of the object picture of follow-up this application of recovery;
Optionally, in the embodiment of the present invention file system that the color data of described object picture can be stored to setting or database.
Step S120, discharge the internal memory shared by color data of described object picture.
Optionally, an object picture is all to there being a color data object, and this color data object is the color data of object picture, stores the Pixel Information of corresponding object picture; The embodiment of the present invention directly can delete color data object corresponding to object picture, realizes the release to the internal memory shared by the color data of object picture.
The Memory Optimize Method that the embodiment of the present invention provides, can when detecting that application switches to background application, determine that described application need discharge the object picture of color data, after the color data of described object picture is stored, discharge the internal memory shared by color data of described object picture, reach the object reducing terminal device running memory.The Memory Optimize Method that the embodiment of the present invention provides, is not limited to the configuration of internal memory hardware, under lower hardware cost, can realize the optimization to terminal device running memory, reduces the running memory of terminal device.
