Problems solved by technology

[0003] Some detection methods, such as Wechat’s stuttering detection solution, use ASM stub insertion, which supports the positioning of fps and stack acquisition, but you need to analyze the stack yourself according to the method id of ASM stub insertion, which has high positioning accuracy and consumes performance. Small, but somewhat invasive to the code

Embodiment 1

[0025] The embodiment of the present invention provides such as figure 1 The freeze information collection method of the application shown in the application is applicable to the Android system and includes:

[0026] S1. Determine the frame drawing object, and establish a corresponding callback mechanism;

[0027] S2. Obtain the stack of the main thread based on the asynchronous thread method according to the specified time interval;

[0028] S3. When the frame drawing execution time exceeds the freeze threshold, output a log including stacks.

[0029] The frame drawing object is a component that processes display rendering in the Android system, that is, a component that executes frame drawing. In this embodiment, it is mainly aimed at Choreographer. Then establish a callback mechanism, which is used to monitor the Choreographer, and when the Choreographer is executing a certain function / step, it returns a message to indicate that the corresponding function / step is executed...

Embodiment 2

[0045] This embodiment is used to specifically illustrate the freeze information collection process of the application:

[0046] 1. The refresh rate of the Android system is 16.67ms, because the refresh rate set by Android is 60FPS, that is, the refresh rate of 60 frames per second, and the refresh rate is about 16ms, so the system will send a Vsync signal (vertical synchronization) every 16.67ms signal) to trigger the rendering of the interface. If there are factors that cause stuttering in the page, it will cause frame loss and stuttering. (Correspondingly, 16.67ms can be set as the specified time interval above)

[0047] 2. Create an object that receives the Vsync signal, the object requests the Vsync signal and gets a callback, and performs the next step at the callback (that is, the doFrame() method in the monitoring callback of Choreographer).

[0048] 3. Record the time point of the previous frame drawing every time, and calculate the difference value based on the time...

Abstract

The invention discloses an application program lag information acquisition method and device, and the method comprises the steps: determining a frame drawing object, and building a corresponding callback mechanism; according to a specified time interval, obtaining a stack of a main thread based on an asynchronous thread mode; when the execution time of the frame rendering exceeds a lag threshold,outputting a log including the stack. The device is suitable for the method. According to the embodiment of the invention, the frame drawing object is determined, and the corresponding callback mechanism is established, so that the parameter for judging the lag can be obtained; through the time interval, data can be reasonably collected, the burden of the system can be reduced, the influence on the system can be reduced as much as possible in an asynchronous thread mode, and therefore extra jamming can be prevented; and if the execution time exceeds the lag threshold, a log which can be used as data for analyzing the lag reason is output.

Description

technical field [0001] The invention relates to the technical field of application programs, in particular to a method and device for collecting stall information of application programs. Background technique [0002] When the application is in use, there will be a phenomenon of freezing, which will affect the user's use. Therefore, in the development and maintenance phase, it is necessary to analyze the cause of the freeze. [0003] Some detection methods, such as Wechat’s stuttering detection solution, use ASM stub insertion, which supports the positioning of fps and stack acquisition, but you need to analyze the stack yourself according to the method id of ASM stub insertion, which has high positioning accuracy and consumes performance. Small, but somewhat invasive to the code. Contents of the invention [0004] The embodiments of the present invention aim to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of ...
