Optimization of power assisted performance of QPM suspended window

QPM Open source address ：https://github.com/ZhuoKeTeam/QPM

Let's try to make some floating window functions that can be visualized , It can display some basic performance index data .

start-up App Then you can see some data , Unresolved root The mobile phone can't get data .

Package name

One apk There will be a fixed package name , But in some special situations , Multiple package names will be displayed , for example ： Test package , Official package , Variant package , Push test package, etc , to QPM Show the package name of the current application , It is convenient for us to locate the problem at some time . for instance ： We have been testing the push package before , Sometimes you need to switch to the official package , Switch between the two packages RD,ST Environmental Science , Finally, I don't remember what bag I used , Can only uninstall , reinstall .QPM The floating window of can directly display the package name of the current application , You can see it at a glance , In fact, the current process can also be + The thread number is printed , It is convenient for students to analyze problems .

At present Activity Name

Just imagine , Did 5 Years of the project , Let the newcomer take over ？ Or a colleague leaves , Drop a pile of holes , I need you to fill the hole . After sorting out the process according to the code , It may not be able to take over immediately , If you look for Activity, One word ———— tired ！

If you can directly display the current interface Activity name , Is it easier ？

CPU and Memory

Why is the interface so blocked , Quickly optimize . You may wonder where to start ？ First render from the interface , Or from a business perspective ? The key is that we need to know what scenarios on the page will cause problems , It is easy to judge if there is an intuitive indicator . When CPU arrive 200% When , Memory explosion , There must be a problem , You can use performance tools to analyze this page in detail . Generally, first look at the interface CPU and Whether the memory is abnormal , Combine with the business logic to obtain the relevant data in advance or delay , Reduce concurrent access at the same time , So as to reduce the jamming of the main interface .

Number of threads

What the hell is this ？ I still remember that the boss once said to reuse threads , Don't do it alone . If you find that 200 Multiple threads , Then you have to consider whether you need a thread pool . It can be handled according to the existing logic , Not absolute .

Activity Stack

Remember just learning Activity At that time ,Activity Of Four kinds of LaunchMode, Here you can record a stack of Activity The order of . It is convenient for you to intuitively understand the situation in the stack .

Traffic

We App How much traffic did your request use ？ May be in 3G/4G More concerns , Although most of them are now WIFI, But our users will use under certain circumstances 3G/4G, So I still have to pay attention .

How about the network ？ For example, I use Wifi, The Internet speed is poor in some corners , There is not even traffic data , We all hope to know .

At some point , The page is blank ？ Why is there no data , You can try to see the download speed .

Especially for some small videos that have been invited more and more , You may be concerned about how much traffic is used .

Screen Recording

be based on Android 5.0 Of API, Record the entire screen , It is convenient for you to repeat some questions about operation records .

monitor H5 page

It needs to be matched with the corresponding settings , We can do that WebView Asynchronously detect any web page in , For example, get the current page address , Homepage white screen loading time , And the request time for each resource , And request resource addresses . Very easy to .

Five customized external styles

A unique identifier for , It means a item, If you want to add multiple , The unique identifier can be set to different .

• Large file box style

QPMManager.getInstance().showBigText(flag, bigText);
The first parameter flag It's the only sign , the second bigText Is to customize all text data displayed in the floating window .

• Key value pair text style

QPMManager.getInstance().showKeyValue(flag, key, value);
The first parameter flag It's the only sign , the second key Is displayed in the custom floating window key value , The third is In the suspended window value value .

• Key graph style

QPMManager.getInstance().showKeyPic(flag, key, picRes);
The first parameter flag It's the only sign , the second key Is displayed in the custom floating window key value , The third is In the suspended window pic Res Resource values in .

• Graph value style

QPMManager.getInstance().showPicValue(flag, picId, value);
The first parameter flag It's the only sign , the second key Is displayed in the custom floating window key value , The third is In the suspended window pic Res Resource values in ( You can put it in your Lord App in ).

• Custom style

QPMManager.getInstance().showCustom(flag,QPMTemplateCustomRenderer);
The first parameter flag It's the only sign , the second QPMTemplateCustomRenderer It is to customize the layout you want to add in the floating window , You can write a class , Inherited from QPMTemplateCustomRenderer, Implement the methods inside , The corresponding contents can be displayed on the floating window .
