Before wait-plugin

wait = new WebDriverWait(driver, 30);
wait.until(presenceOfElementLocated(MobileBy.AccessibilityId("login"))).click();
wait.until(presenceOfElementLocated(MobileBy.AccessibilityId("slider1")));
driver.findElementByAccessibilityId("slider1").click();

WebElement slider1 = wait.until(presenceOfElementLocated(MobileBy.AccessibilityId("slider1")));

After wait-plugin

driver.findElementByAccessibilityId("login").click();
