I am using Appium 1.4.8 for iOS . I have build the code in simulator using xcode and successfully able to launch the server as well as Appium Inspector. But while running my code it is throwing the below error.
我在 iOS 上使用 Appium 1.4.8。我已经使用 xcode 在模拟器中构建了代码，并成功启动了服务器和 Appium Inspector。但是在运行我的代码时，它抛出了以下错误。
My capabilities are @BeforeMethod public void setUp() throws MalformedURLException{
我的能力是@BeforeMethod public void setUp() throws MalformedURLException{
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("appium-version", "1.0");
capabilities.setCapability("platformName", "iOS");
capabilities.setCapability("platformVersion", "8.4");
capabilities.setCapability("deviceName", "iPad 2");
capabilities.setCapability("app", "/Users/arunhs/Desktop/AppiumReq/SRC/build/Debug-iphonesimulator/ComplianceWire.app");
driver = new AppiumDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
}
}
Error is:

This happens because the previous session wasn't shutdown properly and it happens when there is exception thrown in your test. Restart the appium server and try it , it should resolve the issue.
发生这种情况是因为前一个会话没有正确关闭，并且在您的测试中抛出异常时会发生这种情况。重启appium服务器试一下，应该可以解决问题。
Alternatively if you starting appium as node process, you can give option '--session-override true'and this would avoid this problem
或者，如果您将 appium 作为节点进程启动，您可以提供选项'--session-override true'，这将避免此问题

The following is working for me. I am testing by connecting Android device. Please make changes as per your need and apply, this should work now.
以下是为我工作。我正在通过连接 Android 设备进行测试。请根据您的需要进行更改并申请，现在应该可以使用了。
DesiredCapabilities capabilities = new DesiredCapabilities().android();
capabilities.setCapability("no",true);
capabilities.setCapability("newCommandTimeout", 100000);
capabilities.setCapability("noReset", true);
capabilities.setCapability(CapabilityType.BROWSER_NAME, "");
capabilities.setCapability(CapabilityType.VERSION, "4.4.2");
capabilities.setCapability("deviceName", "Galaxy nexus");
capabilities.setCapability("app", application.getAbsolutePath());
capabilities.setCapability("automationName", "selendroid");
capabilities.setCapability("noRest", true);
driver = new AndroidDriver<MobileElement>(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);

Adding the deviceName in the capabilities helped. In the appium logs I could figure out the missing thing.
在功能中添加 deviceName 有帮助。在 appium 日志中，我可以找出丢失的东西。
