Appium Appium 手机 APP 测试中 Selendroid 能定位到元素，但点击该元素的时候报 An unknown server-side error
环境信息：
Appium(1.4.3)+Android(5.0)
java-client (3.0.0)
最近在做 APP 的测试，automationName 设置为Selendroid, 出现了定位到元素，但是点击元素报 An unknown server-side error
- 使用 chrome 定位节点 -
- 使用 Uiautomator 定位节点 -
如上图我去定位 “2 日” 这个元素，定位方式如下：
By specfied_locator = By.cssSelector(".playgo_list.days_panel>li:nth-child(2)");
点击按钮的操作：
setWebView0Context(driver, "NATIVE_APP");
setWebView0Context(driver, "WEBVIEW_0");
waitForClickabilityOf(specfied_locator);
System.out.println(driver.findElement(specfied_locator).getText());
driver.findElement(specfied_locator).click();
能定位到该元素，而且能获取元素的 text ("2 日")，但是 click 的时候报错如下:

已经排查，页面加载完毕，而且元素只有一个，现在没有好的解决方案
这个问题已经困扰一个礼拜了，绝不是伸手党 ，恳请大神帮忙看下！！！
哪位大神能帮忙解决下这个问题

@monkey @lihuazhang @seveniruby 已经修改好排版， 麻烦帮忙看下问题
setWebView0Context
waitForClickabilityO
是什么?
和 click 前那四句有关的 log 呢？
#5 楼 @sanlengjingvv 就是将 setWebView0Context 的方法是在 webview 和 native 之间转换 waitForClickabilityO 是等待页面加载，确认元素已经出现 ，log 日志我已经贴上了 帮忙看下
AndroidWebElement.java:233 行，可能是 selendroid 的问题。
int xSize = (new Double(result[0])).intValue();
int ySize = (new Double(result[1])).intValue();
return new Point(topLeft.x + xSize / 2, topLeft.y+ ySize / 2);
用 js 点行吗
WebElement element = driver.findElement("");
JavascriptExecutor js = (JavascriptExecutor)driver;
js.executeScript("arguments[0].click();", element);
#9 楼 @sanlengjingvv 尝试了下
js.executeScript("arguments[0].click();", specfied_locator );
没有报错， 但也没有点击到这个元素
#8 楼 @lihuazhang 这个方法之前试验过 只能获取元素在弹框的坐标 还要获取弹框的坐标 想问下还有其他的简单直接的方法吗
13 楼 @seveniruby 我之前也没有碰到这个问题，现在是启动 Appium，pom 文件中是 java—client 是版本是 3.0， 难道版本还不够高
此文甚好 容我细品
#17 楼 @seveniruby 我已经将 Appium 升级到 1.4.16 ，但是 rerun 的时候仍报上面的那个错误，在 build/selendroid 的目录下，查看到
而https://github.com/selendroid/selendroid/blob/master/pom.xml 是 0.18 是不是要更新到最新版的 selenroid
楼主， 你问题解决了吗？我也遇到了和你一样的问题。不过我试 mac 版本的。测试 ios。选取相册中 “提取” 按钮。mac 版本好像最高才 1.4.13.。。。
http://www.cnblogs.com/fnng/p/3288444.html 这个帖子解决了我的问题。
楼主是携程的啊？
能吐个槽吗，携程买火车票提前支付，结果没抢到还提前自己退款了，是什么鬼啊。
@tobe_nb 是的，反正每次报 An unknown server-side error 我就用 ActionChains(driver).context_click(z).perform() 就解决了（关键字：mac，ios，appium，python）
我的源码：
import unittest
from selenium.common.exceptions import NoSuchElementException
from selenium.webdriver.common.action_chains import ActionChains
from Package import Sign
from time import sleep
class account(unittest.TestCase):
def chaxun(self):
try:
driver = Sign.fzl.denglu(self)#获取登陆
driver.find_element_by_xpath('//UIAApplication[1]/UIAWindow[1]/UIATabBar[1]/UIAButton[3]').click()#点击银联商户
driver.find_element_by_xpath('//UIAApplication[1]/UIAWindow[1]/UIATableView[1]/UIATableCell[1]/UIAButton[3]').click()#点击对账报表
z = driver.find_element_by_xpath('//UIAApplication[1]/UIAWindow[1]/UIATextField[1]')#点击开始时间
ActionChains(driver).context_click(z).perform()
uiautomator 获取页面元素中文乱码，机型安卓 5.0.2，请问能解决吗
请问楼主这个问题解决了吗，我也遇到了相同问题，很困扰啊
