How to control android device using appium and python?

Not sure about appium, but AndroidViewClient/culebra can easily do what you want.

Install it, run culebra with or without GUI (-G) and you will be able to automatically generate python tests or plain scripts.

For example, if you run

$ culebra -GuU --scale=0.5 -o chrome.py

while the device is on the home screen and click the Chrome icon to open it, this script will be generated

#! /usr/bin/env python

if __name__ == '__main__':
    CulebraTests.main()

then you can run it as

$ ./chrome.py

to achieve the same at any time

I think the problem is like mine...want to control an android device or emulator with Appium, may be Mayank Shivhare already try to learn culebra and found the fact that....culebra is still not support by python 3 yet (same problem like me that prefer python 3.7 than python 2.7).

I have the same problem..., what I understood right now is:

1. All environment should be set up first

2. The emulator should be run first...before type any code

3. then run Appium to make a gateway with IP and port.

4. the missing link is how to connect an emulator to appium via ip and port that provide by appium server.

5. I can detect the emulator element by run 'uiautomatorviewer.bat' from sdk\tools\bin folder, the problem is the problem in number 3, is how to send a command to the emulator via appium. so the command to control emulator base on data that given by 'uiautomatorviewer.bat'

coding is about trial and error, so we need live interaction, to build source code. every developer has a personal interest in build a script or source code. so..to make easier, as beginner, we need live interaction that shows every error in every step our script or to make sure that every line of our script that we type is run smoothly in the android device or emulator.

The problem in learn appium is all manual already given finished script...without a really-really basic explanation...in my case, how to connect appium to emulator, send a command from python console, and see the script is work or not...

what I mean is... we need the step by step explanation of script...because every beginner developers need a live 'trial and error' experience to understand how it works...
