Problems solved by technology

Memory leak refers to those resources that have been used but are no longer used, but this part of memory has not been released in time, and this part of resources has always existed in memory, and this area can neither be used nor released
Since this piece of memory has been occupied and cannot be released in time, in other cases, when it is necessary to apply for memory again but cannot apply for enough memory space, the system will freeze, and in severe cases, the application may crash and other consequences.
It can be seen that the memory leak has brought us very bad results

Abstract

The invention discloses an application program memory leakage detection method. The method comprises the following steps of creating a weak reference monitor for each application program; when an application program runs, monitoring an Activity object of the corresponding application program through the weak reference monitor; packaging the Activity object as a weak reference object; detecting whether the weak reference of the Activity object exists or not; when it is determined that the weak reference of the Activity object exists, triggering a garbage collection mechanism, and marking the Activity object; detecting whether the Activity object is recovered or not; when it is detected that the Activity object is not recovered, obtaining a memory snapshot file of the application program; and analyzing memory leakage according to the memory snapshot file, generating an analysis report and reporting the analysis report. The invention further provides an application program memory leak detection device, electronic equipment and a storage medium. The invention belongs to the technical field of security monitoring, can accurately and quickly locate the memory leakage problem of an application program, and improves the efficiency and accuracy of application program memory optimization.

Description

technical field [0001] The present invention relates to the technical field of memory management, in particular to a method, device, electronic equipment and storage medium for detecting application program memory leaks. Background technique [0002] With the increasing demand for computer applications, the design and development of application programs have also become increasingly complex. After the application programs in electronic devices run for a period of time, the memory of electronic devices will become less and less. caused by a memory leak. Memory leak refers to those resources that have been used but are no longer used, but this part of memory has not been released in time, and this part of resources has always existed in memory, and this area can neither be used nor released. Since this piece of memory has been occupied and cannot be released in time, in other cases, when it is necessary to apply for memory again, but cannot apply for enough memory space, the ...
