The invention provides a memory allocation method and system for solving the problem of insufficient memory for applied pictures. The method comprises the following steps: S1, applying picture resources; S2, judging whether the picture resources exists or not, if yes, withdrawing memory allocation, and, if no, executing S3; S3, judging whether a picture layer where the current picture locates is in a user visible picture layer or not, if no, withdrawing memory allocation, and if yes, executing S4; S4, judging whether the memory of an intelligent mobile terminal is sufficient for allocating memory for the applied picture resources or not, if yes, executing S5, and if no, executing S6; S5, allocating memory for the applied picture resources; S6, judging whether picture resources which are not in the user visible picture layer exist in a memory heap or not, if no, stopping allocating memory for the applied picture resource and withdrawing memory allocation, and if yes, executing S7; S7, recovering the memory for picture resources which are not in the user visible picture layer; returning for executing S4. According to the invention, the problem of insufficient memory for the applied picture can be effectively solved.
Description
technical field [0001] The present invention relates to the technical field of memory management in mobile terminals, in particular to the technical field of image memory management, and specifically relates to a memory allocation method and system for solving insufficient memory for applying for images. Background technique [0002] In the mobile terminal system, the problem of memory overflow (OOM, Out Of Memory) will be encountered from time to time, that is, the memory is not enough. In particular, when a large number of pictures are used, the probability of this problem is relatively high. After this problem occurs, the corresponding application will often be forcibly closed, which brings great inconvenience to the user. [0003] The reason for this problem is that when applying for memory allocation for pictures, a judgment will be made on the memory space that needs to be applied. If the current size of the heap plus the size of the memory that needs to be allocated a...
