Hi I am new to appium, I am trying to launch the app but getting following error. Can some one help me in this. I am using device

Here is the code
AndroidDriver driver;
@Test(priority = 1)
public void test1_addAds() throws Exception {
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(MobileCapabilityType.PLATFORM_NAME, “Android”);
capabilities.setCapability(MobileCapabilityType.DEVICE_NAME, “HY7HHIVC4STKMVWG”);

    driver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
    /*****/
    sleep(3000);
}

@Test(priority = 2)
public void test2_addAds() throws Exception {
    sleep(1000);
    swipe();
    swipe();
    swipe();
}

public void swipe() throws InterruptedException {
Dimension size = driver.manage().window().getSize();
int startx = (int) (size.width * 0.90);
int endx = (int) (size.width * 0.10);
int starty = size.height / 2;
// System.out.println("startx = " + startx + " ,endx = " + endx + " , starty = " + starty);
//Swipe from Right to Left.
Thread.sleep(1000);
driver.swipe(startx, starty, endx, starty, 1000);
Thread.sleep(1500);
}

Here is the error log
