Example one
Fig. 1 is a flowchart of a method for generating a memory image file according to an embodiment of the present disclosure, where this embodiment is applicable to a situation where a memory usage status is monitored according to a memory image file, and the method may be executed by a device for generating a memory image file according to an embodiment of the present disclosure, where the device may be implemented by software and/or hardware and integrated in a terminal device, and the method specifically includes the following steps:
s110, when the state value of the target process of the target application is updated, the occupied memory of the target process is read.
The target application is an application installed in the terminal device, and may be a news client, a browser, or a music player, for example. The terminal device may be any Android system mobile phone, tablet, or vehicle-mounted terminal device, which is not limited in the present disclosure.
The target process of the target application is a program execution process of the target application, and generally, one target application corresponds to one target process. The target process state value ADJ is used for representing the state and the priority of a target process, the states of the target process represented by different values of the target process state value are different, and the states of the target process in the Android system can be divided into the following states according to the priority: the system comprises a foreground process, a visible process, a service process, a background process and an empty process, wherein the priority of the foreground process is the highest, and the priority of the empty process is the lowest.
The memory occupied by the target process refers to the size of the memory occupied by the target process, and for example, the memory occupied by the browser is 100MB, and the memory occupied by the music player is 30 MB. When the target process state value of the target application is updated, the fact that the occupied memory of the target process may change is indicated.
For example, when the target process state value of the target application is updated, the method for reading the occupied memory of the target process may be to read the occupied memory of the target process when the Activity Management Server (AMS) detects that the target process state value of the target application is updated, or may be to write the occupied memory corresponding to the target process into a memory log file when the Activity management server detects that the target process state value of the target application is updated, and write the memory log file into a log system based on a log library interface; and reading a memory log file in a log system and an occupied memory of a target process in the memory log file through a command line tool.
And S120, if the occupied memory is larger than a memory threshold value, generating a memory mirror image file of the target process according to preset memory mirror image logic.
The memory mirror image file refers to a backup file of memory data, and is generally a file with a dump as a suffix name, and can be used for avoiding data loss caused by memory failure.
The memory threshold value may be set according to actual requirements, or may be determined according to the memory capacity of the terminal device.
Illustratively, when it is determined by the memory monitor that the occupied memory corresponding to the target process of the target application is greater than the memory threshold, the memory data of the target process is acquired, and the memory image file of the target process is generated according to the preset memory image logic.
It should be noted that the active mirror image logic is built in the Android system, and the memory mirror image file generated according to the active mirror image logic often includes useless data, so that the generated memory mirror image file has a large data volume, which easily causes system load aggravation, and an application program has no response, even cannot generate a mirror image file. Therefore, the preset memory mirroring logic may be other logic for generating an image file than the source mirroring logic in the Android system, for example, may be mirroring logic for discarding useless data. When the occupied memory is larger than the memory threshold value, the source mirror image logic arranged in the Android system is abandoned, and the memory mirror image file of the target process is generated by adopting the preset memory mirror image logic, so that the mirror image file is prevented from being cut after the source mirror image logic in the Android system is adopted to generate the mirror image file.
Optionally, the method further includes:
and generating a memory state report according to the memory mirror image file.
Illustratively, after a memory image file of a target process is generated according to a preset memory image logic, according to the memory image file, memory data in the memory image file is extracted to generate a memory state report, so as to realize real-time monitoring of the target process of a target application, and also realize optimization of a memory use state according to the memory state report.
According to the technical scheme of the embodiment of the disclosure, when the state value of the target process of the target application is updated, the occupied memory of the target process is read; if the occupied memory is larger than the memory threshold value, a memory mirror image file of the target process is generated according to the preset memory mirror image logic, and a memory mirror image can be generated according to the preset memory mirror image logic to realize memory optimization analysis, so that the mirror image file is prevented from being further cut, the load of a server is reduced, the success rate of the memory mirror image is improved, and the real-time performance, the accuracy and the stability of memory monitoring are further improved.
Example two
Fig. 2 is a flowchart of a method for generating a memory image file according to a second embodiment of the present disclosure, which is embodied on the basis of the second embodiment, in this embodiment, when a state value of a target process of a target application is updated, reading an occupied memory of the target process includes: when the target process state value of the target application is updated, writing the occupied memory corresponding to the target process into a memory log file; writing the memory log file into a log system based on a log library interface; reading a memory log file in a log system and an occupied memory of a target process in the memory log file by a command line tool, wherein the method of the embodiment specifically comprises the following steps:
s210, when the state value of the target process of the target application is updated, writing the occupied memory corresponding to the target process into a memory log file.
The memory log file is a record file or a file set for recording memory data.
When an Activity Manager Service (AMS) detects that the state value of a target process of a target application is updated, namely when the occupied memory corresponding to the target process is changed, the event log server EventLog writes the occupied memory corresponding to the target process into a memory log file by the target application.
And S220, writing the memory log file into a log system based on a log library interface.
The log library is a unit for collecting, storing and querying log data in log service.
Illustratively, a log library interface provided by a log library writes a log file containing an occupied memory corresponding to a target process into a log system. The log library interface is not limited in the embodiment of the present disclosure, and may be a SOCKET interface, for example.
And S230, reading a memory log file in the log system and the occupied memory of the target process in the memory log file through a command line tool.
The command line tool is used to parse the format of the memory log file into a recognizable format, for example, the command line tool may be Logcat. And reading a memory log file in the log system through a command tool Logcat, and further reading the occupied memory of a target process in the memory log file.
Generally, a mode of acquiring the memory occupied by the target process is usually an active polling mode, that is, a preset memory monitoring logic is embedded into each target application through an Axis2 archive (AAR) of an Android system, and the memory occupied by the target process is actively acquired, which brings about a main problem that if the polling frequency is too fast, resources are wasted, and if the frequency is too slow, an accurate current memory value cannot be acquired.
In the embodiment of the present disclosure, when the memory state value changes, the target application writes the occupied memory corresponding to the target process into the memory log file of the log system, and reads the memory log file in the log system through the memory monitor to obtain the occupied memory of the target process. The occupied memory of the target process is obtained by adopting a passive reading mode, and the problem caused by an active polling mode is solved.
S240, if the occupied memory is larger than the memory threshold value, generating a memory image file of the target process according to preset memory image logic.
According to the technical scheme of the embodiment of the disclosure, when the target process state value of the target application is updated, the occupied memory corresponding to the target process is written into the memory log file; writing the memory log file into a log system based on a log library interface; the method comprises the steps of reading a memory log file in a log system and an occupied memory of a target process in the memory log file through a command line tool, if the occupied memory is larger than a memory threshold value, generating a memory mirror image file of the target process according to preset memory mirror image logic, obtaining the occupied memory of the target process in a passive reading mode, improving the real-time performance, accuracy and stability of memory monitoring, generating a memory mirror image according to the preset memory mirror image logic to achieve memory optimization analysis, avoiding further cutting of the mirror image file, reducing server load and improving the success rate of memory mirror image.

s310, when the state value of the target process of the target application is updated, the occupied memory of the target process is read.
And S320, if the occupied memory is larger than the memory threshold, acquiring memory data corresponding to the preset memory mirror image logic and the target process.
The preset memory mirror image logic is logic for generating a memory mirror image file according to memory data. The preset memory mirror image logic is used for discarding basic data, objects with small internal opposite value changes and non-memory leakage, and data with invalid memory optimization or unnecessary data in the memory data when generating the memory mirror image file according to the memory data. The preset memory logic may be stored in a memory of the target application, and the embodiment of the present disclosure is not limited thereto.
Illustratively, if the occupied memory is greater than the memory threshold, the preset memory mirror logic is acquired, and an instruction is sent to the target process to acquire the memory data of the target process.
S330, cutting the memory data corresponding to the target process through the preset memory mirror image logic to obtain target memory data.

Optionally, in this embodiment of the present disclosure, the cutting the memory data corresponding to the target process through the preset memory mirror logic to obtain target memory data includes:
determining data to be discarded according to the preset memory mirror image logic;
and cutting the data to be discarded from the memory data corresponding to the target process to obtain target memory data.
The data to be discarded can be set according to the user requirement, and can also be set according to the use purpose of the memory image file.

Optionally, the data to be discarded includes: basic data type, array, incubator data, photo memory buffer data, placeholder, and/or image pixel data.
Optionally, in this embodiment of the present disclosure, the preset memory mirror logic is packaged in a library file.

In the embodiment of the disclosure, useless data can be abandoned from the source by abandoning the source mirror image logic in the Android system and adopting the preset mirror image logic with direct cutting capability to generate the mirror image file. However, since the Android system permission setting cannot directly call the library file of the preset memory mirror logic, the value of the class loader of the memory data of the target application needs to be set to be a null value so as to pass the permission check of the Android system.
