Issue with Scrolling in Android Native app using Appium

Question

For my Native Android App , I have been trying for the past 2 weeks to get appium to scroll down on my native app. I have tried driver.scrollTo("Accounts"); Then I got this error

[org.openqa.selenium.WebDriverException: CATCH_ALL: io.selendroid.server.common.exceptions.SelendroidException: method (by) not found: -android uiautomator

and many other examples that I have found. Nothing seems to work . This is the latest example that I have tried .

Using appium 1.5.2 and appium java client version: '3.3.0'. When I try to run the following code.

    TouchAction tAction=new TouchAction(driver);
    int startx = driver.findElement(By.id("line_chart_line_chart")).getLocation().getX();
    int starty = driver.findElement(By.id("line_chart_line_chart")).getLocation().getY();
    int endx = driver.findElement(By.id("actionBarLogo")).getLocation().getX();
    int endy = driver.findElement(By.id("actionBarLogo")).getLocation().getY();
    System.out.println(startx + " ::::::: " + starty + " ::::::: " + endx +  " ::::::: " +  endy);
    //  This is what the console printed out  startX=560 ::::::: starty=1420 ::::::: endx=560 ::::::: endy=240  
    //First tap on the screen and swipe up using moveTo function
    tAction.press(startx,starty).moveTo(endx,endy).release().perform();

Then I get this error message

org.openqa.selenium.WebDriverException: An unknown server-side error occurred while processing the command. Original error: Could not proxy. Proxy 
error: Could not proxy command to remote server. Original error: 404 - undefined (WARNING: The server did not provide any stacktrace information)
Command duration or timeout: 27 milliseconds

I am at a loss on what to do. In order to click on an element it has to be visible on the screen . In order for this element to appear on the screen I need to scroll down to it.

Is there something that I am doing wrong??? I just can't seem to figure it out.

Answer 1

You used Selendroid mode, which does not support UiAutomator By method. You can change your appium running mode to UiAutomator by setting desired capability automationName to Appium

Answer 2

This function does the trick for me, put in "Accounts" for elementName when calling it in your case.

public static void scrollToElementAndroid(AndroidDriver driver, String elementName, boolean scrollDown) {
    String listID = ((RemoteWebElement) driver.findElementByAndroidUIAutomator("new UiSelector().className(android.widget.ListView)")).getId();
    String direction;
    if (scrollDown) {
        direction = "down";
    } else {
        direction = "up";
    }
    HashMap<String, String> scrollObject = new HashMap<String, String>();
    scrollObject.put("direction", direction);
    scrollObject.put("element", listID);
    scrollObject.put("text", elementName);
    driver.executeScript("mobile: scrollTo", scrollObject);
}

Use code like below:

Dimension size = driver.manage().window().getSize();
int x = size.width / 2;
int endy = (int) (size.height * 0.75);
int starty = (int) (size.height * 0.20);
driver.swipe(x, starty, x, endy, 1000);
