Description
Technical Field
The invention relates to the technical field of computers, in particular to a method, a device, a medium and electronic equipment for analyzing memory performance.
Background
The existing application program often needs to occupy a large amount of memory during running, so that the problem of large memory occupation is easily caused.
In practical applications, if the memory is not used properly, the process of the application program is not crashed immediately, but has a long latency period. The memory problem is caused by many reasons, for example, the memory problem is often difficult to locate due to the influence of the path depth or the influence of the interaction mode.
The process of memory leakage is monitored through the LeakCanary library, and the reason of the memory leakage is analyzed through the LeakCanary library. However, the problems of the existing leakcarary library are many, which are specifically as follows:
the prior art analyzes and processes the memory performance as follows:
step a1, an application program accesses to a LeakCanary library.
Step a2, registering activity and fragment life cycle call-back.
And a step a3, detecting whether the object is recycled or not in the runtime.
And a4, unloading the memory snapshot.
And step a5, starting a new process.
Step a6: analysis of the object reference chains was performed.
And a step a7, if the analysis result exists, popping up a notice.
The above-mentioned memory performance analysis and processing processes have the following problems:
problem 1: the product must be accessed into a LeakCanary library to be used offline. If no bring-to-line is desired, an additional branch or packing configuration needs to be maintained.
Problem 2: the process of analyzing the memory performance through the LeakCanary library is executed at the mobile phone end. The mobile phone terminal runs the process of analyzing the memory performance through the LeakCanary library, so that the running speed is low, a central processing unit is consumed, and other modules of the mobile phone terminal are influenced.
Problem 3: in the process of analyzing the memory performance through the leak bank at one time, even if other leakage problems are monitored, other monitored leakage problems cannot be analyzed, and only one leakage can be analyzed at one time, so that the phenomenon of report missing easily exists in the process of analyzing the memory performance.
Problem 4: at the mobile phone end, the abnormal phenomenon of memory overflow can occur at the mobile phone end through the process of analyzing the memory performance by the LeakCanary library.
