無法在appium自動化期間切換android應用程序

Question

我有以下代碼。

DesiredCapabilities capabilities =DesiredCapabilities.android(); 
capabilities.setCapability("device","Android"); 
      capabilities.setCapability("deviceName","hammerhead"); 
      capabilities.setCapability("platformName","Android"); 
      capabilities.setCapability("appPackage","com.android.calculator2"); 
      capabilities.setCapability("appActivity","com.android.calculator2.Calculator"); 
AndroidDriver driver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities); 
      driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS); 
      driver.findElement(By.xpath("//*[@resource-id='com.android.calculator2:id/digit_7']")).click(); 
      driver.findElement(By.xpath("//*[@resource-id='com.android.calculator2:id/op_add']")).click(); 
driver.startActivity("com.android.browser","com.android.browser.BrowserActivity"); 

「java.lang.reflect.InvocationTargetException」在執行driver.startActivity行時發生錯誤。我在這裏犯了什麼錯誤？

Answer 1

Invocation Target Exception:- This exception occurs when an underlying method throws an exception. So if there is any method that is invoked using Reflection API throws any runtime exception, the Reflection API will wrap that exception in InvocationTargetException

您可以通過使用getCause()方法對InvocationTargetException找出原/實際exception。

Answer 2

我也有同樣的問題。這是由於StringUtils的問題。我下載了Apache Commons Lang插件，問題解決了。

下載可以在這裏找到： http://commons.apache.org/proper/commons-lang/download_lang.cgi

下載後，在IDE中添加的commons-lang3-3.4.jar到外部庫。
