Unable to click or tap on button using appium driver

[cpintea]

I have this configuration which starts the android emulators and load the url in chrome.
androidEmulator:
autoload:
'': %paths.base%/bootstrap/
extensions:
Behat\MinkExtension:
base_url: http://google.com
javascript_session: 'foo'
sessions:
foo:
appium:
browser: "Chrome"
appium_host: "http://127.0.0.1"
appium_port: "4723"
# use chrome browser
# browser capabilities
capabilities: {"platformName": "Android", "deviceName": "Android Emulator", "browser": "Chrome", "avd": "NexusSAPI28", "noReset": false}
suites: # list of test suites available for current profile ("default" in this case)
default: # this suite is called "default"
paths: # check these paths
features: %paths.base%/Features
bootstrap: %paths.base%/Android/bootstrap/
contexts: # use these contexts (test suites)
- FeatureContextAndroid: # FeatureContext class"
- Behat\MinkExtension\Context\RawMinkContext

The step implementation:
$session = $this->getSession();
$element=$session->getDriver()->find("$xpath") => return null every time.
It is possible to use the configuration above and identify elements in a Chrome browser on an android device?
If i use directly "facebook/php-webdriver" to initialize the driver i can access the page element with
$drv=self::createDriver();
$drv->get($url);
$element = $drv->findElements(WebDriverBy::partialLinkText("FRANÇAIS"));

For me it look like the AppiumFactory.php implementation in MinkExtension have no functionality to search elements on mobile devices.

Or , maybe i am on wrong path here. Any ideas how to use the MinkExtension (appium) to be able to identify elements on chrome (Android)?
