step S10, acquiring a preset core process of a Native framework layer of the mobile terminal in the system starting process;
the card screen detection method is applied to the mobile terminal shown in fig. 1, and the mobile terminal can comprise a smart phone or a tablet computer with an Android (Android) system. At present, functions of a mobile terminal are more and more powerful, the increase of the functions can lead to the increase of hardware, and the increase of the hardware can increase software driving, resource loading or initialization processes, so that a starting-up starting process is long, a previous process in the starting process can influence a later process, and the slow starting condition occurs. The embodiment is provided with a starting standardized mechanism, and the starting process of the Android system is combed, so that the starting process of the system is divided into five stages, namely a minimum system power-on and starting stage, a kernel layer power-on and starting stage, a Native layer starting stage, a framework layer starting stage and an application layer starting stage, and each starting stage is divided into an inherent part and a self-defined part of the Native system. After the starting process of the system is standardized, the processes are classified according to the process creation related to the execution of each stage flow after standardization. In the system starting process, data related to hardware and resources are mainly loaded and initialized, and processes related to the system starting process are divided into a core process and a non-core process according to the influence of the hardware and the resources on the system after the starting process is completed.

The Android (Android) comprises a C part and a Java part, the former is established on the basis of Linux, the latter is established on the basis of JVM, and the two parts are connected through Zygote. The Zygote process performs operations such as initialization of a virtual machine, loading of a library, loading of a prefabricated library and the like in the starting process of the system, and meanwhile, when the system needs a new virtual machine, the Zygote creates the virtual machine by copying the Zygote process. If the operation flow having a critical influence on the system starting in the process is found to have a large influence on the card screen of the mobile terminal in the using process, the flow A can be added as the core flow to monitor the core flow. And after the core flow is determined, setting monitoring points of the core flow according to a preset monitoring rule. If the core flow is a loading library, presetting the flow of the loading library in the monitoring rule, monitoring whether the loading path of the loading library is correct, and monitoring the size of the memory required by the loading library.

Furthermore, after the monitoring result information of the core process is obtained, whether the card screen fault occurs in the mobile terminal can be judged according to the monitoring result information. The preset monitoring rule comprises a monitoring point related to a monitoring position, a reference result used for judging whether the monitoring result information represents the card screen fault of the mobile terminal or not, and the monitoring result information obtained by monitoring is compared with the reference result to judge whether the monitoring result information and the reference result are consistent or not; when the judgment result is consistent, the monitoring result information shows that the mobile terminal has no card screen fault; and when the judgment result is inconsistent, the monitoring result information shows that the mobile terminal has a card screen fault. If the loading path of the monitoring loading library is from A to B, namely the monitoring result information is from A to B, and the reference result in the preset monitoring rule is from A to C, the monitoring result information is judged to be inconsistent with the reference result, and the monitoring result information shows that the card screen fault occurs in the mobile terminal. After the card screen fault of the mobile terminal is monitored, the reason of the card screen fault, namely the monitoring result information and the time of the card screen fault is stored, so that the reason of the card screen can be known by reading the stored information when the mobile terminal is monitored subsequently.

According to the scheme, the core process in the preset core process of the Native framework layer is monitored when the mobile terminal system is started through presetting the monitoring rule. When the core process is abnormal and causes the card screen, the reason causing the card screen can be found in time according to the monitored result information. After-sales personnel or developers can conveniently and quickly and accurately locate the reason of the card screen of the mobile terminal when monitoring the reason of the card screen of the mobile terminal, and the labor cost and the time cost are greatly reduced.

Further, the core flow of this embodiment includes creating a path, registering information, preloading data, and a synchronization lock read during creating the path, registering information, and preloading data, that is, a flow having a critical influence on system startup in such a zygate process is used as the core flow. Specifically, the creation path is a main execution function creation/data/dalvik-cache path of the Zygote process; the main execution function of the Zygote process as the registration information registers the socket for Zygote; the data in the preloaded data includes classes and resources, which are preloaded for the main execution function of the zygate process. The synchronization lock is used to ensure that resources are used by a single thread at the same time. Because multiple threads share the same resource, when multiple threads use the resource at the same time, the execution result of the thread is wrong. Therefore, if the current thread uses the resource, the current thread and the resource are synchronously locked, so that the resource cannot be used by other threads, and other threads cannot use the resource until the current thread finishes executing. In the embodiment, the operation of reading the synchronous lock in the process of establishing a/data/dalvik-cache path, registering a socket for Zygote and preloading data is taken as a core flow, so that the phenomenon that the synchronous lock is read wrongly in the process, the execution result of a thread is wrongly executed and a screen is blocked by the mobile terminal is avoided. Considering that the classes and resources preloaded by the Zygote process are numerous, the preloaded classes of the present implementation include: classes located in/system/etc/preloaded-classes files; the preloaded resources include: dracable and color resources; in addition, preloading data can further comprise: the method comprises the steps of preloading OpenGL, loading classes through a System, loadLibrary () method, preloading 3 shared libraries such as 'android', 'builder _ rt' and 'jnigraphics', and preloading text connector resources.
When core process monitoring is performed according to preset monitoring rules, the monitoring rules set in the preset monitoring rules are different according to different types of the core processes. Specifically, when the core flow is a path creation, whether the creation of the main execution function/data/dalvik-cache path of the Zygote process is successful is monitored; when the core flow is the registration information, monitoring whether a main execution function of the Zygote process is successful in registering the socket for the Zygote; when the core flow is the preloading data, monitoring whether the class and the resource are preloaded successfully by the main execution function of the Zygote process; when the core process is reading the synchronous lock in the process of creating the path, registering the information and preloading the data, monitoring whether the read synchronous lock is blocked or deadlocked in the process of creating the path, registering the information and preloading the data; the synchronous lock blocking is the condition that when a thread uses a resource, the thread occupies the resource for too long time due to some reasons, other threads needing to use the resource wait for time, and cause blocking, and the synchronous lock deadlock is the condition that two threads respectively need the resource held by the other thread and wait for each other. When the synchronous lock is blocked and deadlocked, the execution result of the thread is influenced, the starting of the system is influenced, and the screen of the mobile terminal is blocked. Therefore, according to the detection rules, the core processes are judged to obtain judgment results, and the judgment results are used for generating monitoring result information.
Further, based on the first or second embodiment, a third embodiment of the card screen detection method of the present invention is provided, in the third embodiment, the step of determining whether the card screen fault occurs in the mobile terminal according to the monitoring result information includes:
step S31, judging whether the monitoring result information is consistent with preset reference information;
step S32, when the monitoring result information is consistent with preset reference information, judging that no card screen fault occurs in the mobile terminal;
and step S33, when the monitoring result information is consistent with preset reference information, judging that the mobile terminal has a card screen fault.
Furthermore, in order to determine whether the monitoring result information includes information that causes the mobile terminal to have a card screen fault, the present embodiment is preset with reference information, that is, preset reference information. After the monitoring result information is acquired, whether the monitoring result information is consistent with preset reference information or not is judged, if the monitoring result information is consistent with the preset reference information, the core flow for starting the system is represented as a normal starting flow, the mobile terminal can be judged not to have a card screen fault, if the monitoring result information is inconsistent with the preset reference information, the core flow for starting the system is represented as an abnormal state, and the mobile terminal is judged to have the card screen fault. The preset reference information is different for different core flows, and when the core flow is a path creation, the preset reference information is a path creation success identifier; when the main execution function of the Zygote process successfully establishes the/data/dalvik-cache path, returning monitoring result information as a successful establishing identifier; when the creation is failed, the identifier is the creation failure identifier; therefore, when the monitoring result information is the identifier which is successfully created, the monitoring result information is consistent with the preset reference information, and the core flow of the created path is judged to be normal. Correspondingly, when the core flow is registration information, presetting reference information as a successful registration identifier; when the core flow is the preloaded data, the core flow is a loading success identifier; and when the core flow is to read the synchronous lock in the processes of creating the path, registering information and preloading data, the core flow is to read the successful identifier. Understandably, the system is started as a result of all core processes, so that the mobile terminal can be judged to be normally started only when the monitoring result information of each core process is consistent with the preset reference information; and when any item is inconsistent with the preset reference information, the screen clamping phenomenon of the mobile terminal can be judged. In addition, the determination of successful loading of the preloaded data is also determined by multiple factors, which can be specifically classified into a name, a path, a required memory size, whether the required memory exceeds the available memory, whether a mapping table established after the memory application is successful is correct, and the like. And judging that the loading is successful only if all the factors are normally monitored, otherwise, an error can be caused by any error. If the preloaded resource is a color resource, monitoring a path error during loading, judging that the preloaded resource is wrong, returning a loading error identifier, and judging that the card screen fault occurs in the mobile terminal if the preloaded resource is inconsistent with the preset reference information.
Further, based on the first, second, or third embodiment, a fourth embodiment of the card screen detection method of the present invention is provided, where in the fourth embodiment, the step of determining that the card screen fault occurs in the mobile terminal includes:
and step S34, collecting monitoring result information in real time, and storing the collected monitoring result information after carrying out redundancy removal processing within preset time.
Furthermore, when the mobile terminal is judged to have the card screen fault, the monitoring result information is collected in real time so as to reflect the reason of the card screen of the mobile terminal in real time, and the collected monitoring result information is subjected to redundancy removal processing and then stored in the preset time. The preset time is a reasonable redundancy removing interval time determined through experiments, and in the interval time, data needing redundancy removing are not too much or too little, so that too long time is spent or redundancy removing is too frequent. The redundancy removing process is to integrate the monitoring result information collected in the preset time into an information output and storage, wherein the information comprises the reason type of the card screen, the time point of occurrence and the frequency of occurrence of various types. If the preset time is one hour, 100 pieces of monitoring result information are received within the preset time between 9 points and 10 points, wherein the number of card screens caused by path creation failure is 30, the number of card screens caused by registration information failure is 50, and the number of card screens caused by color resource preloading failure is 20, the 100 pieces of monitoring result information are integrated into one piece of information including type, number and time point to be output and stored, and the type and time point of the 100 pieces of information are prevented from being output and stored respectively, so that the storage space is saved.
Further, based on the fourth embodiment, a fifth embodiment of the card screen detection method of the present invention is provided, in the fifth embodiment, after the step of performing redundancy removal and post-processing on the collected monitoring result information within a preset time and storing the collected monitoring result information, the method includes:
step S35, judging whether the size of the stored data volume exceeds the size of the preset data volume, when the size of the stored data volume exceeds the size of the preset data volume, selecting information to be deleted from the stored monitoring result information, and deleting the information to be deleted.
Understandably, the storage unit in the mobile terminal is divided into a plurality of storage sections, each storage section is used for storing different data, and the capacity of each storage section is constant, that is, the amount of data which can be stored is constant. Accordingly, the capacity of the storage interval for storing the monitoring result information is also constant, and when the monitoring result information is stored in the storage interval within the preset time, the amount of data stored in the storage interval is increased continuously and may exceed the capacity. Therefore, after the monitoring result information is subjected to redundancy removal processing and stored, whether the size of the stored data volume exceeds the size of the preset data volume is judged, and the size of the preset data volume is the capacity of the storage area for storing the monitoring result information. When the size of the stored data amount exceeds the preset data amount, it is described that the capacity of the storage interval is used up, data storage can no longer be performed, and the stored data needs to be deleted. And selecting information to be deleted from the stored monitoring result information, and deleting the information to be deleted. The selection principle can be based on the time sequence, and the earlier the time sequence is, the longer the current time of the monitoring result information is, the less the referential significance is, so that the monitoring result information is selected as the information to be deleted for deletion.
Further, referring to fig. 4, based on the first, second, third, fourth, or fifth embodiments, a sixth embodiment of the card screen detection method of the present invention is provided, in the sixth embodiment, after the step of determining whether the card screen fault occurs in the mobile terminal according to the monitoring result information, the method includes:
and step S40, when the mobile terminal has a card screen fault, outputting the monitoring result information to a feature log file.
Furthermore, when the mobile terminal is judged to have the card screen fault according to the monitoring result information, the monitoring result information is output to the feature log file. Specifically, a thread can be independently created to output monitoring result information to a debug process, the debug process is a diagnosis process for abnormal exit of a program of the Android system, and the debug process can detect program crash and output process state information during the crash to a file and a serial port for a developer to analyze and debug. The implementation outputs the monitoring result information to the Debugerd process, and the Debugerd process directionally outputs the monitoring result information to the characteristic log file with the Debugerd authority processing. Therefore, when monitoring and positioning of the card screen reasons are carried out on the mobile terminal by developers, the card screen reasons can be quickly and accurately positioned by inquiring the characteristic log file, and the labor cost and the time cost are reduced.
