abstract :

     
  Because the command line tool of lightning simulator is very suitable for the third party code control , So more and more people begin to use lightning simulator for scripting , The development of reverse engineering software . However, many people are not clear about the principle and method of using program to control lightning simulator . So I take the one that's easier to get started Python Code as an example , Explain the control process of lightning simulator from principle to method .

Control principle of lightning simulator

     
  After installing the lightning simulator , You can find it under the installation directory ldconsole.exe and ld.exe Two command line programs . in addition , After starting the lightning simulator , Can be shared in a folder → Advanced options Windows route . This path and simulation system /sdcard/Pictures route , The two are logical . That is, copy the file to the /sdcard/Pictures Under the path , Corresponding Windows There will be one more such path under the path . This is for map recognition scripts , It's very friendly —— Because in the simulator, the screenshot does not need to go through dump step , You can read and process the graph directly on the control host . In addition, it can even be dynamic on both sides , Efficient transmission of shared files , It's all about the rest of the simulator .

     
  Let's talk about it ld and ldconsole Two orders .Ld Commands are used to execute adb command , But it's not the same as normal adb The difference is that , You don't need to know the serial number of the simulator device , Instead, you can send commands directly through the serial number . There's no feedback and the goal doesn't exist very quickly . This can speed up the efficiency of the script , And improve the stability of the script —— Because it doesn't exist and it doesn't collapse . in addition ld The connection to the command is very stable , It's not physically affected USB The influence of line , It's not going to be unstable . This is for scripts that need to run for a long time , It's a fatal attraction .

     
 ldconsole It's also a good tool , It can control the setting of simulator parameters , include imei, serial number , Mobile phone number resolution and other parameters , It can also detect and control the startup and shutdown of the simulator . It can even simulate input , Key , Sliding and other operations . And this kind of simulation operation is the development interface of the simulator itself , than adb More stable and sensitive , Very suitable for developers .

        To sum up , Control principle of lightning simulator , In fact, it controls the behavior of the simulator by controlling the command line interface .
