I am switching to WEBVIEW performing some functions,and again switching back to NATIVEAPP but elements are not located,when NATIVEAPP switch is done.

My code Snippet: Hybrid Switch

Set<String> getContexts=ElementsAction.driver.getContextHandles();
		for(String setContext:getContexts)
		{
			System.out.println("get" +setContext);
			if(setContext.contains("WEBVIEW"))
			{
			System.out.println("For WEB");
			ElementsAction.driver.context(setContext);
			System.out.println("setting content");
			String title=ElementsAction.driver.findElementById("SS_DocumentTitle").getText();
			System.out.println("The title is " +title);	
			ElementsAction.driver.context("NATIVE_APP");
			System.out.println("switch to Native");
			break;
			}

One running the above code the NATIVEAPP switch is also done

Click on a Native App Elements, iam not able to locate the element and getting the below error on console
ElementsAction.driver.findElement(By.name(signOut_name)).click();

Getting this error in console on
