RemoteWebDriver + AndroidDriver：與瀏覽器通信錯誤

我最近開始使用 - > RemoteWebDriver + AndroidDriver。我已經開始與一個基本的例子如下：RemoteWebDriver + AndroidDriver：與瀏覽器通信錯誤

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」打開google.com成功地在模擬器上。的問題是，「stmt3」 &「stmt4」不工作.Emulator關閉的webdriver和日食發生以下情況除外：

問題是我使用了android 2.3.3（薑餅上的bug可能導致WebDriver崩潰）。在升級到android 4.0.3時，代碼運行良好。

從堆棧跟蹤，似乎你的硒版本是2.12.0。當前版本是2.25.0。可能使用最新版本可以解決問題。

好的一點你可以看到在2.12和2.25之間有關於android的變化。閱讀更新日誌。 – user1258245 2012-07-17 07:22:13

這不是使用2.24的問題，我得到相同的錯誤日誌 – Mandy 2012-07-17 08:32:38
