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
By specfied_locator = By.cssSelector(".playgo_list.days_panel>li:nth-child(2)");
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:
org.openqa.selenium.WebDriverException: An unknown server-side error occurred while processing the command. (WARNING: The server did not provide any stacktrace information)
