First thing, if u r using API 4.4.2 then why do u run test with selendroid mode. So first change this to Appium mode. Kindly run ur scripts and let me know the results.

Thanks,

i tried this test code:  
Set contextNames = driver.getContextHandles();

```
    for (String contextName : contextNames) {

        System.out.println(contextName); 

    }

```

and it returns  
WEBVIEW\_com.test.android.trivialdrivesample

how to set the param of driver.context();  
driver.context(“WEBVIEW”) ?
