RemoteWebDriver + AndroidDriver：与浏览器通信错误

Question

我最近开始使用 - > RemoteWebDriver + AndroidDriver。我已经开始与一个基本的例子如下：

stmt1:WebDriver driver=new AndroidDriver(); 
stmt2:driver.get("http://www.google.com"); 
stmt3:WebElement element = driver.findElement(By.name("q")); 
stmt4:element.sendKeys("Cheese!"); 

“stmt1”，“stmt2”打开google.com成功地在模拟器上。 的问题是，“stmt3” &“stmt4”不工作.Emulator关闭的webdriver和日食发生以下情况除外：

问题是我使用了android 2.3.3（姜饼上的bug可能导致WebDriver崩溃）。在升级到android 4.0.3时，代码运行良好。

Answer 2

从堆栈跟踪，似乎你的硒版本是2.12.0。当前版本是2.25.0。可能使用最新版本可以解决问题。
