scrollTo(String text) and scrollToExact(String text) method of Android Driver not working

Using the scrollTo(String text) and scrollToExact(String text) method of Android Driver. However the scrolling is done for the entire contact list first downwards and then upwards but it does not scroll upto the string text provided and in the end throws error- org.openqa.selenium.NoSuchElementException: An element could not be located on the page using the given search parameters.

public class test2 {

//public WebDriver driver;
public AppiumDriver driver1;

@BeforeClass
public void setUp() throws MalformedURLException{

//Set up desired capabilities and pass the Android app-activity and app-package to Appium

DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("platformName", "Android");
capabilities.setCapability("platformVersion", "5.0
capabilities.setCapability(CapabilityType.BROWSER_NAME, "");
capabilities.setCapability("deviceName", "4763f751");
capabilities.setCapability("device", "Android");
capabilities.setCapability("appPackage", "com.android.contacts");
capabilities.setCapability("appActivity", "com.android.contacts.activities.PeopleActivity");

//Create RemoteWebDriver instance and connect to the Appium server.
driver1 = new AndroidDriver (new URL("http://127.0.0.1:4723/wd/hub"), capabilities);

}

@Test
public void testCal()  throws Exception {

String txt= clk.getText();
driver1.scrollTo(txt);

}
@AfterClass
public void teardown(){
//close the app

one way is to make the String string1 static

public class Favourites extends ActionBarActivity {

public static  String string1;
String st2;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.fav);
final Button but1 = (Button) findViewById(R.id.button1);

and

Favourites.string1 = Athenry;

Because you did declare the access modifier for the variable string1. It is private by default. You have to make it public like this:

public String string1;

But that is a bad practice. You would want to have getter and setters for these kinds of jobs. So basically this:

private String string1;
public String setString1(String s){
string1 = s;
}

And you access it by calling the method

Object.setString("Your String");
