Appium scrolling with TouchAction - appium-android

Question

I am using the below code for scrolling:
There is no error from eclipse but during execution I am getting error as “java.lang.ClassCastException: java.lang.NoSuchMethodError cannot be cast to java.lang.Exception” at the first line itself. It did not execute the second line. Please help.
Appium version: 1.10.0
Java Client: 6.1.0
TouchAction action = new TouchAction((MobileDriver) driver.getWebDriver());
action.press(PointOption.point(startx,starty)).waitAction(WaitOptions.waitOptions(Duration.ofMillis(50))).action.moveTo(PointOption.point(startx, endy)).release().perform();

Answer 1

This is my swipe method. It works with versions 6.1.0 and 7.0.0 of Appium.
You can use this codes.
public void swipeWithRatio(int startXRatio, int startYRatio, int endXRatio, int endYRatio, int durationMiliSec) {
Dimension d = getPhoneSize();
int height = d.height;
int width = d.width;
int swipeStartWidth = (width * startXRatio) / 100;
int swipeStartHeight = (height * startYRatio) / 100;
int swipeEndWidth = (width * endXRatio) / 100;
int swipeEndHeight = (height * endYRatio) / 100;
new TouchAction(driver)
.press(point(swipeStartWidth, swipeStartHeight))
.waitAction(waitOptions(Duration.ofMillis(durationMiliSec)))
.moveTo(point(swipeEndWidth, swipeEndHeight))
.release()
.perform();
}
// Swipe from up to down example
// It starts from 25 percent of the screen and continues to 75 percent.
swipeWithRatio(50,25,50,75,2000);
// Swipe from down to up example
// It starts from 75 percent of the screen and continues to 25 percent.
swipeWithRatio(50,75,50,25,2000);
