selendroid 模式下可以正常运行，但是到滑动欢迎页面的时候，突然报错。

关于这段的源代码

public static AppiumDriver androidSwipe(AppiumDriver driver) throws Exception {
        logger.info("＃＃＃＃＃Step0.1:define X, Y, duration ");
        Sleeper.sleep();
        int xStart = 600;
        int yStart = 200;
        int xEnd = 20;
        int yEnd = 200;
        int duration = 1000;
        driver.swipe(xStart, yStart, xEnd, yEnd, duration);
        return driver;
    }

把这段给注释掉后，居然不识别 app 的所有的元素。（appium 模式下可以识别，定位。）
