How to perform scroll in appium 1.6.4 and java client 5.0.0 beta7

Plz provide me possible number of alternatives to scroll down android screen up and down without using swipe method and touch action class. I am not able to perform scroll feature in android app version 21. Below is my code.

package com.raaga.demo;

import java.io.File;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.List;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.testng.annotations.Test;

import io.appium.java_client.TouchAction;
import io.appium.java_client.android.AndroidDriver;

public class MainTest {
        private AndroidDriver<WebElement> driver;

        @Test
        public void setUp() {
                File apkFile = new File("./Raaga.apk");
                DesiredCapabilities cap = new DesiredCapabilities();
                cap.setCapability("platform", "Android");
                cap.setCapability("deviceName", "Andriod Device");
                cap.setCapability("app", apkFile.getAbsolutePath());
                cap.setCapability("commandTimeOut", "2*60");
                cap.setCapability("appPackage", "com.raaga.android");
                cap.setCapability("appActivity", "com.raaga.android.SplashScreen");

                try {
                        driver = new AndroidDriver<WebElement>(new URL("http://ift.tt/1sv2im4"), cap);
                } catch (MalformedURLException e) {

                        e.printStackTrace();
                }
                try {
                        driver.manage().timeouts().implicitlyWait(90, TimeUnit.SECONDS);
                        driver.findElement(By.id("com.raaga.android:id/skip_text")).click();
                        driver.findElementById("com.raaga.android:id/landing_skip_to_raaga").click();
                        List<WebElement> ele = driver.findElements(By.className("android.widget.TextView"));
                        System.out.println(ele.size());
                        System.out.println(ele.get(1).getText());
                        ele.get(1).click();
                        driver.findElementById("com.raaga.android:id/toolbar_logo").click();
                        System.out.println(driver.findElementById("com.raaga.android:id/menu_music_btn").getSize());
                        driver.findElementById("com.raaga.android:id/menu_music_btn").click();
                        System.out.println(driver.findElementById("com.raaga.android:id/slidingmenumain").getSize());
                        System.out.println(driver.getCapabilities());
                        Thread.sleep(30000);
                 //   driver.findElement(MobileBy.AndroidUIAutomator("new UiSelector().text()"));
                        TouchAction ac=new TouchAction(driver);
                        ac.moveTo(driver.findElement(By.id("com.raaga.android:id/artists_radio_lay1"))).release().perform();
                
                        
                
//                      Boolean result = driver.findElement(By.xpath("//android.widget.TextView[@index='0']")).isDisplayed();
//                      while (result) {
//                              driver.swipe(0, 853, 0, 122, 2000);
//                              if (result==true) {
//                                      
//                                      break;
//                              }
//
//                      }


                } catch (Exception ex) {
                        ex.printStackTrace();
                }

        }

}
