title: desired capabilities not recognized by appium
body: <p>My desired capabilities from code are like below:</p>
  
  <pre><code>DesiredCapabilities capabilities = new DesiredCapabilities();
      capabilities.setCapability(MobileCapabilityType.VERSION, "4.4.2");
      capabilities.setCapability(MobileCapabilityType.PLATFORM_NAME,
          "Android");
      capabilities.setCapability(MobileCapabilityType.DEVICE_NAME,
          "Android emulator");
  capabilities
          .setCapability(MobileCapabilityType.BROWSER_NAME, "Browser");
      try {
          driver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"),
              capabilities);
      } catch (MalformedURLException e) {
          e.printStackTrace();
      }
  driver.navigate().to("http://google.com");
  </code></pre>
  
  <p>My appium server debug info is showing below lines:</p>
  
  <pre><code>&gt; info: --&gt; POST /wd/hub/session {"desiredCapabilities":{"browserName":"Browser","platformName":"Android","version":"5.1.1","deviceName":"Android emulator"}}
  &gt; info: Client User-Agent string: Apache-HttpClient/4.3.3 (java 1.5)
  &gt; info: [debug] The following desired capabilities were provided, but not recognized by appium. They will be passed on to any other services running on this server. : version
  </code></pre>
  
  <p>Note: I have the AVD started with the same desired capabilities. Still it is showing the same message. And browser is opened in one of the already started AVD randomly.</p>
  
  <p>Thanks in advance.</p>
