Description

TeleniumTestCase refuses to communicate with app because get_token request returns None.

    @classmethod
    def start_process(cls):
        ...
        # ensure the telenium we are connected are the same as the one we
        # launched here
        if cls.cli.get_token() != cls.telenium_token:
            raise Exception("Connected to another telenium server")

In the start_android_process function, the TELENIUM_TOKEN is sent along with other environment variables (perhaps specified by the user) to the android device as a file (/sdcard/telenium_env.json) but this file is never read and therefor the environment variables are never set.

Unfortunately there doesn't seem to be a way to set these environment variables remotely with adb so TeleniumTestCase can't setup the environment before launching the app. We could make use of custom android system properties but this would affect people who have worked around the current situation already by adding code that sets environment variables via /sdcard/telenium_env.json. So it's probably best to stick with the current approach. That said, I believe telenium should be the one loading up these environment variables when the client is started. Although the user doesn't have to do much from a python perspective he'd still have to give the app the right permissions to access this file. So I am adding a bit of code in telenium_client.py.

PR on the way soon.
