Originally reported on Google Code with ID 2359

After starting a new android emulator, and binding my driver, when i try to navigate
to a webpage, i get the following exception.

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/selenium-2.5.0-py2.7.egg/selenium/webdriver/remote/webdriver.py",

    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: None ; Stacktrace: Method handle
threw an error in WebDriverHandler.java 

Details:
Python 2.7.2
SE 2.5

Steps:
from selenium import webdriver
driver = webdriver.Remote(desired_capabilities="ANDROID", command_executor='http://localhost:8080/wd/hub')
driver.get('http://www.google.com')
--insert exception here

however, using the driver.get command on an iphone emulator works without error.

I have experienced this problem as well. Looking at the html content returned from the
get request, the exact Java exception is:

<h2>HTTP ERROR: 500</h2>
<p>Problem accessing /wd/hub/session. Reason:
<pre>    java.lang.String cannot be cast to java.util.Map</pre></p>

Ok so the problem is not coming from the driver.get command but actually it is the initializing
of the driver itself.
It seems that it is expecting a map instance (as indicated by the exception) for the
desired_capabilities option, if you pass desired_capabilities={}, then it should work.
At least it worked for me.

If you do 

from selenium import webdriver

android = webdriver.Remote(command_executor='http://localhost:8080/wd/hub', desired_capabilities=webdriver.DesiredCapabilities.ANDROID)
android.get("http://foo.bar") 

it will work.
