这是网上测试 ContactManager 的例子，一直运行失败，麻烦各位看一下哪位出错了，不知道是什么原因；应该是 capabilities 设置出错了，导致 driver 出错，但我也不知道具体在哪里出错了，求大神帮忙。下面是源码，再往下是日志。
File classpathRoot = new File(System.getProperty("user.dir"));
File appDir = new File(classpathRoot, "apps/ContactManager");
System.out.println(appDir.getAbsolutePath());
File app = new File(appDir, "ContactManager.apk");
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("platformName", "Android");
capabilities.setCapability("deviceName", "Google Nexus S");
capabilities.setCapability("platformVersion", "4.2");
capabilities.setCapability("appPackage", "com.example.android.contactmanager");
capabilities.setCapability("appActivity", ".ContactManager");
capabilities.setCapability("app", app.getAbsolutePath());
driver = new SwipeableWebDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

用 robotframework 写界面自动化测试，如何使用 select checkbox 勾选我想要的复选框？
我的总是报错 ValueError: Element locator 'id=treeDemo_1_check' did not match any elements.
请教给我大侠，什么原因呢？
运行模拟器提示 [2014-07-25 14:53:13 - DeviceMonitor] Sending Tracking request failed!，什么原因呢

#10 楼 @umbrella1978 这里面的 error 不需要管是吧，左边那个图里面的
#8 楼 @umbrella1978 上面这个图看不出来吗？
路径是 D:\AppiumForWindows-1.0.0\sdk\adt\sdk
这个问题我都说过很多遍了。appium 的 sdk 路径里不允许有空格。

这里的文章指出了一个解决方案
注意：ERROR: error: Logcat capture failed: spawn ENOENT
我的也是这个问题，如何解决呢
我遇到和楼主同样的问题，分析正常启动和不能正常启动的 Log,不正常的时候，请求的参数少了 sessionid。
不能正常启动，请求参数中没有 sessionid
正常启动的 logo:
控制台显示的内容是：
