For mobile automation testing, there is an appium can support simulate user actions in the real/virtual mobile device. And robot framework is a automation framework which support create test case in text(robot)/html format, which has a graceful report. Appium has created a lib for robot. So it is easy and quick to create an mobile automation testing with Robot, Appium and Appium for Robot library.
Robot has advantages and disadvantages. Robot is easy to create test case when a general and flexible libraries are created, and it also has a great report. It can also integrated with Jenkins. Its disadvantage is not easy to debug and not suitable for complicated test cases especially need multiple components in testing.
Here is the sample to create a simple mobile automation testing.

Setup Environment

Video reference: https://www.youtube.com/watch?v=8mKcw1waMOU
1. Install python, download python zip and install it by clicking. Set PYTHONPATH. Install setup tools, which is easy for installing python libraries.
https://www.python.org/downloads/release/python-352/
Install easy_install, then install pip.
easy_install pip
2. Install JDK and Eclipse IDE.
3. Install Pydev plugin for Eclipse.
4. Install Appium, download setup and install it.
5. Install robot framework lib and Appium for Robot lib.

Selenium2Library is not (yet) compatible with Python 3.x.

We have a Pull Request (github.com/robotframework/Selenium2Library/pull/564) to have Selenium2Library compatible with all Python versions, but it is not in the official Release, and it was tested with Python 2.6, 2.7 and 3.4.

I you want to install you could try github.com/HelioGuilherme66/robotframework-selenium2library/releases/tag/v1.8.0b1 For example with: pip install -U –pre https://github.com/HelioGuilherme66/robotframework-selenium2library/archive/v1.8.0b1.zip

Create Python Project

Create Custom Library

1. Create your own appium lib which can extend AppiumLibrary. You can add your external methods in his lib. This is not required, if you don’t need extend keywords of AppiumLibrary, you don’t need create your own library.
   CustomAppiumLib.py

import time
from AppiumLibrary import AppiumLibrary

class CustomAppiumLib(AppiumLibrary):
”’
Custom AppiumLibrary, can add extend functions(keywords).
”’

def **click_element_by_id**(self, locator):
    if  'id=' in locator:
        element_loc = locator       
    else:
        element_loc = 'id=' + locator

    self.click_element(element_loc)

def **get_current_application**(self):
    """Get current application instance.        
    """
    return self._current_application()

def **click_element_object**(self, element):
    """Click element identified by `element(WebElement)`.        
    """
    element.click();

def **wait_until_page_contains_elements**(self, loc_list, timeout=30):
    """Wait until page contains element based on locator list.

    Key attributes for arbitrary elements are `index` and `name`. See
    `introduction` for details about locating elements.
    """
    #import sys, pdb; pdb.Pdb(stdout=sys.__stdout__).set_trace()
    if type(timeout)!= int: timeout = int(timeout)
    maxtime = time.time() + timeout*1000
    while True:
        found_elements, found_loc = self._is_elements_present(loc_list)
        if found_elements: return found_loc
        if time.time() > maxtime:
            raise AssertionError("Can't find elements %s in the page" % loc_list)
        time.sleep(0.2)

def **_is_elements_present**(self, loc_list):
    """Verify whether one of elements in locator list is present in the page.

    Key attributes for arbitrary elements are `index` and `name`. See
    `introduction` for details about locating elements.
    """
    if type(loc_list) != list: loc_list = [loc_list]
    found_element = False 
    find_loc = ""       
    for loc in loc_list:
        loc_str = "id=%s" % loc
        self._bi.log("Check whether %s present" % loc)
        if self._is_element_present(loc_str):
            find_loc = loc
            found_element = True
            break;

    return found_element, find_loc

Create Test Cases

1. Create your test case, import AppiumLibrary or your own AppiumLibrary if you have created.
2. Create your test cases with Robot keywords, Appium for Robot keywords and your own keywords.
   Sample of test cases:
   demo.robot - test cases file.

Execute test cases

1. Start appium server. - You can write python keyword to start appium server automatically. （node appium.js)
2. Make sure the project path is added to PYTHONPATH:
   Set PYTHONPATH=%PYTHONPATH%;D:\PythonWS\mms_auto\src;
3. Execute test case with command:
   pybot -V deviceinfo.py demo.robot
