之前使用 Robotium，现在学习 Appium。结果马上被 app 的启动页面卡住了。

前提：

公司产品，安装后启动会有一个四屏的引导页面，左右切换。最后一页可以使用点击或者继续左滑，然后进入首页。
以下是第一张引导页的 uiautomator 的截图：

做法：

setup() 和 tearDown() 就不展示了，直接展示 test 函数

@Test
public void enterCoursesList() throws InterruptedException{

    swipeToLeft(driver, 1000);
    Thread.sleep(1000);
    swipeToLeft(driver, 1000);
    Thread.sleep(1000);
    swipeToLeft(driver, 1000);
    Thread.sleep(1000);
    swipeToLeft(driver, 1000);
    Thread.sleep(1000);

    //进入首页
    Assert.assertEquals("com.fasthand.main.MainTabelActivity", driver.currentActivity());
    WebElement el = driver.findElement(By.name("找机构"));
    el.click();

}

//向左滑屏
public void swipeToLeft(AndroidDriver driver, int time) {
    int width = driver.manage().window().getSize().width;
    int height = driver.manage().window().getSize().height;
    driver.swipe(width * 3 / 4, height / 2, width / 4, height / 2, time);
}

运行结果

运行后，app 启动，然后就出错了。
附上 server log：

有童鞋遇到和我一样的情况吗？去网上查也没看到对这个报错的具体解释。
另外，我感觉这样做滑屏是没问题的，也不知道为什么总是报错。有童鞋也遇到过引导页滑屏的情况吗？可以提供下解决方法吗？

解决

因为报错的时机在启动而不是滑屏，于是使用 try-catch 试了下。

/**
 *  Swipe to left on the screen
 */
public void swipeToLeft(AndroidDriver driver, int time) {
    int width = driver.manage().window().getSize().width;
    int height = driver.manage().window().getSize().height;
    try {
        driver.swipe(width * 3 / 4, height / 2, width / 4, height / 2, time);
    } catch (Exception e) {
    // TODO: handle exception
    e.printStackTrace();
  }
}

这样做之后，再次启动。在 app 启动页面时还是会报同样的错，但 test 没有停止，继续进行就会开始滑屏。
也就是说，滑屏部分应该没有问题。那为什么在启动时报错？报错的时候引导页还没有加载出来。
于是在执行滑屏之前先加了延迟，给了启动页的时间。

@Test
public void enterCoursesList() throws InterruptedException{
    Thread.sleep(5000);
    Assert.assertEquals("com.moduleLogin.welcome.GuidePageActivity", driver.currentActivity());
    swipeToLeft(driver, 1000);
    Thread.sleep(2000);
    swipeToLeft(driver, 1000);
    Thread.sleep(2000);
    swipeToLeft(driver, 1000);
    Thread.sleep(2000);
    WebElement btElement = driver.findElementByClassName("android.widget.Button");
    btElement.click();
    Thread.sleep(5000);

    //进入首页
    Assert.assertEquals("com.fasthand.main.MainTabelActivity", driver.currentActivity());
    WebElement el = driver.findElement(By.name("找机构"));
    el.click();
    Thread.sleep(5000);
}

这样做之后，再次启动，成功！
多谢各位的回答！我开始以为是 swipe 写错的原因，结果是没有给启动足够的时间，非常麻烦诸位！
