Method, storage medium, electronic device and system for automatically releasing file resources

Abstract

The invention discloses a method for automatically releasing file resources, a storage medium, an electronic device and a system, which relate to the field of computer information processing. The method comprises the following steps: a file reading and writing function is set to read and write a file; the read and write function is set to a public type and has a parameter of a file path; the filereading and writing function is set to read and write a file. Verifying the read / write function according to the file path; After the verification is passed, a sub-thread is opened for reading and writing operation; Closing the file stream resource information of the file object read in the read / write operation and releasing the memory resource occupied by the file object; A communication is established between the main thread and the child thread to obtain the file content information read from the child thread. A read-write function is used in the child thread to read and write, and the memory resource occupied by the read file object is cleaned after the read and write is completed, so that the file can be read and written, and the memory resource occupied by the file due to reading a large number of file objects is not caused, and the problem of memory leakage is solved.

Description

technical field [0001] The invention relates to a method for automatically releasing file resources in software memory management, belonging to the field of computer information processing. Background technique [0002] In the development process of Android software, we often use file and other operation functions. File operation involves the application of file resources and the operation of file objects. When using files in traditional solutions, we often forget to release the memory space occupied by the files, which can easily lead to "memory leaks" (Memory Leak, that is, the memory hardware resources of the computer are occupied by useless files for a long time, resulting in the loss of available memory. The space is reduced, just like the memory bank is leaked, so the risk of being named "memory leak") appears, and long-term memory leaks may cause system exceptions and program crashes. [0003] In the traditional solution, the operation file usually has a file handle,...

Problems solved by technology

When using files in traditional solutions, we often forget to release the memory space occupied by the files, which can easily lead to "memory leaks" (Memory Leak, that is, the memory hardware resources of the computer are occupied by useless files for a long time, resulting in the loss of available memory. The space is reduced, just like the memory bank is leaked, so the risk of being named "memory leak") appears. Long-term memory leaks may cause system exceptions and cause program crashes

[0003] In the traditional solution, the operation file usually has a file handle, and various abnormal information will be generated during the reading and writing of the file. If the file class holding the file handle does not release the file handle in time or releases an error, this It is very easy to cause file resources to be occupied or the file cannot be opened

[0004] In other words, memory leaks are prone to occur in the traditional file reading and writing process, and the existing file handle method cannot solve these problems well
