traceview

I'm mainly analyzing the list slippage problem, I'll tell you how I use the tool and how I analyze it.There are two main ways of using TraceView:1. The simplest way is to open DDMS directly, select a process, and then press the "Start Method Profiling" button above, and so on when the red dots turn black, it means that TraceView has started to work. Then I can slide one of the following tables (now the ope

One, select the tracking rangeUse the following two lines of code between the code snippets that you want to base Debug.startmethodtracing ("Love_world_"); Debug.stopmethodtracing (); For example, the method trace between the OnCreate and the OnStart method publicclassmainactivityextendsactivity{ @Override protectedvoidoncreate (Bundle savedinstancestate) { super.oncreate ( Savedinstancestate); setcontentview (r.layout.activity_main);

Subsequent Android traceview usage and listview performance optimization tests (1) Last part of the previous article gave me the code for testing: if you do not see it, please first browse the previous article: Now let's verify the magic of listview. The main thing that listview needs to optimize is the getview () method, which implements the convertview Cache Optimization, the difference between using listview to reuse convertview in

Debuggable Android program debugging tool Highlights of the Code debugging tool provided by Google:TraceviewAndDmtracedump. With these two tools, we can easily Debug programs to analyze bugs. Traceview helps us analyze program performance. dmtracedump generates a function call diagram. Unfortunately, the dmtracedump provided by Google is a failed tool and cannot be drawn. This article will introduce the solution in detail to implement plotting. Genera

I read the following document today, saying that traceview is of great help to program performance and optimization: I am too lazy, and I have not continued to read this article. I have Baidu's traceview usage skills, a lot of resources, and I will introduce how to use it. Recommended: http://blog.csdn.net/itachi85/article/details/6857324 Of course, the specific steps are as follows: I. When creating AVD, t

TraceView is an Android platform equipped with a good performance analysis tool. It can be graphically used to let us know the performance of the program we want to track, and can be specific to method.TraceView IntroductionTraceView is an Android platform-specific data acquisition and analysis tool that is used primarily to analyze hotspots for applications in Android. TraceView itself is just a data analy

TraceView-Carlo InspectionTraceView is an Android platform-specific data acquisition and analysis tool, integrated in the Ddms tool, you can collect methods in the program execution time, call relationship, number of calls and resource consumption.I. Methods of Use1, start the virtual machine/connect the phone, cmd command input DDMS start DDMS tool. Open the app on your phone and select the process to test the app on Ddms. Click the Start Method Prof

What is traceview? Traceview is a good performance analysis tool on the Android platform. It allows us to understand the performance of the program we want to track in a graphical way, and can be specific to the method.Role of traceview 1. view the execution time of the tracing code and analyze the time-consuming operations. 2. It can be used to trace method call

I wrote a demo and used traceview to test the print () method. The last time shown is only 180 ms. Use System before and after the print () method. currenttimemillis () method. The time difference is too long because traceview needs to output the cached information to * at the end of stopmethodtracing *. trace file. android.os.Debug.startMethodTracing("MainActivity-print"); long start = System.curr
