Abstract

The invention provides a picture memory managing method and apparatus for an android operation system. The provided android operation system picture memory managing method comprises the following steps of (a) creating a Lrucache hard reference caching module and setting the caching maximum value of the Lrucache hard reference caching module 1; (b) creating a soft reference picture caching module and setting the number of pictures allowed to be stored in the soft reference picture caching module; (c) creating a picture adding caching module 3 used for loading pictures in the Lrucache hard reference caching module in a memory according to picture addresses sent from application programs; (d) and creating a picture acquisition caching module. When pictures stored before are required by application programs, picture addresses and sizes are sent to the picture acquisition caching module. The picture memory managing method and apparatus for the android operation system can optimize the picture memory use of application programs and make users view pictures in a clear and smooth way. Furthermore, the user experience is improved.

Description

technical field

[0001] The invention relates to the technical field of mobile device memory management, in particular to a picture memory management method and device for an Android operating system. Background technique

[0002] The Android operating system (hereinafter referred to as the system) has been used in various devices including mobile phones, tablets, and set-top boxes. Mobile phones, tablets, and set-top boxes have become indispensable devices for people's leisure and entertainment.

[0003] These devices use text or a combination of text and pictures when interacting with users. The more the display interface is switched, the more pictures need to be used.

[0004] The available memory space of the system for the application is limited, and loading a 1M picture into the memory will occupy about 10M of memory, and the memory allocated by the system for each dalvik virtual machine is limited, such as in Google's G1 , the heap memory allocated to the application ...

Examples

Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] refer to figure 1 .

[0034] The picture memory management method suitable for the Android operating system provided by this embodiment includes the following steps.

[0035] a. Create Lrucache hard reference cache module 1, and set the cache maximum value of Lrucache hard reference cache module 1.

[0036] Lrucache hard reference cache module 1 is a cache module based on the Lru algorithm. The principle of the Lru algorithm is to remove the least recently used data.

[0037] Set the maximum cache value of the Lrucache hard reference cache module 1, which is generally 1 / 8 of the memory available to the application. The size of the Lrucache hard reference cache module 1 can be set according to the needs of the device or application.

[0038] Lrucache hard reference cache module 1 saves data with key and value values. When it is necessa...
