TraceView and androidtraceview of Android Performance Tuning Tool Since the 16 Performance Optimization series Videos released by Google in January, many excellent articles on the optimization series have been found in major communities during this time. I have analyzed the causes of performance, shared how to optimize our applications, and introduced some tools to help us detect performance problems. One

information can be. This technology benefits from the technology described earlier: Android in the root-free hook application of its own system services, the technical principle is very simple, is the use of dynamic Agent technology + reflection mechanism. This technology can be used for this automatic blasting function, we just need to add this hook code at the entrance of the program. This technique has been practiced in the previous article: a new

Android test Appium, Robotium, monkey and other frameworks or tool comparisons1. Appium Test (functional test, user acceptance test, black box test)-Rating:8The Appium test is equivalent to a black box test. Just test UI logic correctness. So the Appium test framework provides limited methods. Gets a Appiumdriver object. The object just has a lot of findelements() methods to get to the UI element. UI elemen

Monkeyrunner ToolsObjective:Recently began to study the Android automated test method, some of the tools, methods and frameworks to do some simple collation, including Android test framework, CTS, Monkey, Monkeyrunner, benchmark, other test tool and so on. Because the contact time is very short, many places have the insufficiency, hoped can communicate with every

What is TraceView?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.The role of TraceViewReview the execution time of the tracking code, and analyze what is a lengthy operationA call that can be used to track methods, especially the method call relationships

collector Android Memory Analysis Tool # # Memory MONITORGC operations need to pause other threads, so a short time-frequent GC can have an impact on the UI thread, causing frequent GC to have two common cases, where a large number of objects are created and released immediately in a short time. For example, creating an object in the OnDraw method of the view-young generation's memory area reaches the

Use of the Android source code repository and Repo ToolPreface I haven't had a weekend off for a long time. Alas, I don't have to talk about it anymore. I have to learn more and enrich myself at any time. ROM Porting is very tedious and involves a lot of knowledge points. Here we will introduce the terms that ROM Porting often hear and the use of Repo tools.AOSP, AOKP, and cm I believe many Android enthusia

the Android community, Kang said it was a custom-made ROM, a ROM from the private sector. CM is the abbreviation of CyanogenMod, the Cyanogen team is the world's largest third-party ROM compilation team, covering a very wide range of models, domestic well-known ROM such as MIUI, Hammer ROM are based on the CM implementation. In a strict sense, CM Rom belongs to the AOKP category. Although the CM ROM has always been in compliance with native

Having previously been an Android, and recently developing an iphone client, the most troubling of all is the inconsistency between the Java, Android and iphone three platforms plus decryption . Because the end of the phone is usually the Java-developed web service,android and iphone clients invoke the same Web Service interface, for data security considerations,

Android debugging tool-mat I. Overview For large Java applications, it is difficult to block all the vulnerabilities even if we perform a lot of effective work in the test phase, many problems will still be exposed in the production environment, and it is difficult to reproduce in the testing environment. The JVM can record part of the running status of the system when a problem occurs and store it in the h

Problems: I see other people's programs, want to learn how people's UI layout is done, how can I snoop into one or two? Problems: When learning viewgroup and layout, we may have a question. If I do not place layout in the XML layout file or directly place textview or other components, how does it layout? Solution:The android SDK comes with a tool for viewing the hierarchical structure of the UI layout: hi

The analysis tool for Android Application Performance Optimization last recorded the process of solving excessive plotting. This time, how can we determine whether the process is smooth and conceptual? In fact, at first I thought it was a bit nonsense, and it was obviously not smooth when I used it. However, this is the same thing as I would like to talk about many applications. It makes sense that the card

An important command that contains the Android emulator operation under the Tools folder of the SDK Adb,adb is all called Android Debug Bridge, which is the role of the debug bridges, with this tool, we can manage the status of the device or phone simulator, and can do the following:(1) Quickly update the code in the device or phone simulator, such as app or

also the set up customized Intents and start a activity with them. (translation is not very good, probably said to rely on injection to produce simulation objects and then simulate the system environment.) ） Controls the control element of the UI and then produces a touch event. This function is similar to that described by Appium.2) Service testing test is the service life cycle is normal3) Content Povider testiing because provider is a data entry, so the test is whether the data can be

Now take a look at the entire interface diagram, the entire interface consists of two parts, the above is the process you test the execution of each thread, each line Chengjian line; The following is the value of each indicator executed by each methodThe above section is the timeline where each thread in your test process runs, and you can see that there is only one main thread executing, because I slipped the list, and the main thread (the UI thread) was drawing the view.
