Appium 测试用例运行卡在了 app 包安装上了，错误日志好像是说有另外一个 session 在运行所以无法创建 session
以下是日志

eclipse 代码如下

public void setUp() throws Exception {
    // set up appium
    File classpathRoot = new File(System.getProperty("user.dir"));
    // 存放app目录：apps
    File appDir = new File(classpathRoot, "apps");
    File app = new File(appDir, "FamilyEducation_DEV_0428.apk");
    DesiredCapabilities capabilities = new DesiredCapabilities();

    capabilities.setCapability("unicodeKeyboard", "True");//支持中文
    capabilities.setCapability("resetKeyboard", "True");//支持中文
    capabilities.setCapability("deviceName","02835ebc2115d2cb");
    capabilities.setCapability("platformName", "Android");
    capabilities.setCapability(CapabilityType.BROWSER_NAME,"");
    capabilities.setCapability(CapabilityType.VERSION, "5.1.0");
    capabilities.setCapability("app", app.getAbsolutePath());
    capabilities.setCapability("appPackage", "com.fasthand.familyeducation");
    capabilities.setCapability("appActivity", "com.moduleLogin.welcome.NewWelcomeActivity");
    //初始化
    driver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities); 
}

开始我以为是因为原来安装的 apk 签名的原因，就把 apk 卸载了，但是还是不行。
Junit 的报错是

每次运行会卡到这一条日志上：

info: [debug] executing cmd: C:\software\android-sdk\tools\adb.exe -s 02835ebc2115d2cb shell rm "/data/local/tmp/KinguserV4.8.1B245.apk" && rm "/data/local/tmp/Kinguser
V4.8.5B255.apk" && rm "/data/local/tmp/cdb96382c6d52f5284d4e2480ff40c66.apk" && rm "/data/local/tmp/mq_1458735647.apk" && rm "/data/local/tmp/mq_1458735681.apk"

我没明白为什么会有 Kinguser V4.8.5B255.apk 的日志？

现在依旧不明白原因，只是看到卡到 Kinguser 这里了，猜测可能是之前用 Kingroot 来 root 手机后来把 Kingroot 卸载了出的问题？重新下载了 Kingroot，然后就好了。。。
但是 Kingroot 跟 appium 有什么关系？appium 不是不需要 root 权限吗？
