Test WebView used within android native app

Unfortunately currently robotium does not support testing of webview even if it is used with native app but there is a way to test webview using Android WebDriver. So the solution is using combination of robotium + android webdriver. Here is the sample code to test contents of webview.
Little background about AUT: Native app has a button (assume ‘Google’) clicking on which opens webview with google.com.

Sample Code:
Activity mActivity = getActivity();
WebView web;
ArrayList<View> views = solo.getCurrentViews();
for(View view : views) {
if(view instanceof WebView) {
web = (WebView) view;
break;
}
}
WebDriver driver = new AndroidWebDriver(mActivity);
driver.get(web.getOriginalUrl());
WebElement element = driver.findElement(By.name("q"));
element.sendKeys("Test");
element = driver.findElement(By.xpath("//span[text()='Google Search']"));
element.click();
