However, compared with the UITableView provided by the native on iOS, its UI capabilities are insufficient. For example, it does not support native animation e

Both are graphical tools. Hierarchy Viewer usage analysisProgram. Open toos/hierachyviewer. bat, and the left side shows the UI components of the programs in the virtual machine in a tree structure. Each node represents a button, textview, and so on.

Android performance detection tool -- traceview1. What should we do if we want to test the code section in the code area marked for testing the gridView setting adapter? It's easy. Use two lines of code to hold it ~ Original code: mPhotoWall.

Android platform that can help developers find hotspots.A TraceView Introduction 1.1 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 analysis tool, and data acquisition requires the use of the Debug class in t

: Scheduling delay (scheduling delay), when a frame drawing time of more than 19MS will trigger the hint, not to mention that this frame has nearly 40ms. The main reason for this problem is that the thread is not assigned to the CPU time slice for a long time when it is drawn, and therefore cannot continue drawing. Press the M key to highlight the time period, and we'll look at the CPU situation as shown in.You can see that two CPUs are running at full capacity during this time period. As for wh

the application, then, let the user download other content of the application based on the specific device.Tip 8: Use Hierarchy ViewerThe Hierarchy Viewer tool helps you remove vulnerabilities in the application layout. It also provides a lot of valuable information, such as how long each View takes to control. Find the domain to which the problem belongs, which makes it easier to solve the problem.Tip 9: Use the layoutopt ToolThe layoutopt tool is a simple command line tool that helps you iden

has three colors, where green means the frame rendering smooth, yellow and red represents the rendering time of more than 16.6ms, which is more serious red. We click on the red F Circle and will give the frame information as shown in.As you can see, frame gives the problem hint: Scheduling delay (scheduling delay), when a frame drawing time of more than 19MS will trigger the hint, not to mention that this frame has nearly 40ms. The main reason for this problem is that the thread is not assigned

Android monitorFor the debug version of the application, use Android Studio's own Android Monitor tool to observe a process for that app.By detecting the CPU, network and GPU of a process, it can be seen that the behavior of the process is abnormal in a static state, and if it is abnormal, it can be returned to the code to find out the anomaly.1-4 using the TraceView in DDMS to locateThe TraceView tool is

) Method profiling (method analysis) is a tool of ddms. It is very useful for quick overview of the time consumption distribution in an application. It can also be used for detailed viewing of time-critical functions. Figure 6 When an application runs and executes an interesting task, if you want to obtain more performance data about the task, click Start method profiling )". Analyzer only collects a small amount of data (not seen for more than 2 or 3 seconds), so click the icon again in a few

Android performance optimization is a common problem in Android development. Next, we will give a brief summary of the knowledge points of Android performance optimization, which will be summarized in terms of tools and code. For better work, you must first sharpen the tool. This article first looks at Android performance optimization tools. TraceViewtraceview is a self-contained tool in the Android SDK. It can perform statistical analysis on the time consumption of method calls in applications.

Android performance optimization is a frequently encountered problem in Android development, next will be the Android performance optimization of knowledge points to do a simple comb and summary, will be from the tools and code two aspects of combing. The so-called 工欲善其事 its prerequisite, this article first look at the Android performance optimization has what powerful tools.Traceviewtraceview is a tool that comes with the Android SDK, and it's a very important tool for Android performance optim

or 3 seconds), so click the icon again after a few minutes to stop the collection. Activating the method Analyzer from DDMS enables the tool to automatically use internal storage to store analysis results, and when the capture is complete, send them back to the host for further analysis.The IDE automatically launches the TraceView window to help you analyze the results in the IDE (Figure 7).Figure 7Parsing results is the most interesting part.
