Selendroid - 无法连接到 Selendroid 服务器，假设它没有运行

Question

我正在尝试使用 selendroid 在浏览器中自动执行一些操作。我设法让服务器运行起来。如果我去http://localhost:4444/wd/hub/status，这是回复

{"value":{"os":{"name":"Linux","arch":"amd64","version":"4.6.4-1-ARCH"},"build":{"browserName":"selendroid","version":"0.17.0"},"supportedDevices":[{"emulator":false,"screenSize":"(480, 800)","serial":"47900eb4d5dc9100","platformVersion":"17","model":"GT-I8200","apiTargetType":"google"}],"supportedApps":[{"mainActivity":"io.selendroid.androiddriver.WebViewActivity","appId":"io.selendroid.androiddriver:0.17.0","basePackage":"io.selendroid.androiddriver"}]},"status":0}

显示设备也被识别。我正在使用通过 USB 连接的真实手机。 一切看起来都不错，但是当我启动测试脚本时，手机启动了应用程序，但 selendroid 服务器却告诉它无法连接。

selendroid 的输出如下图所示。还有更多，但从这里开始。

如果我让它继续运行，它只是停留在一个循环中，不断显示该错误，可能正在尝试重新连接。

我正在使用最新的 selendroid 版本，selendroid-standalone-0.17.0-with-depende，从他们的网站获得：http://selendroid.io

我正在运行的测试脚本是用 python 编写的。这里是：

#!/bin/python2.7

import unittest
from selenium import webdriver

class FindElementTest(unittest.TestCase):

    def setUp(self):
        d = webdriver.DesiredCapabilities.ANDROID
        print d
        self.driver = webdriver.Remote(
            desired_capabilities=d
        )
        self.driver.implicitly_wait(30)

    def test_find_element_by_id(self):
        self.driver.get('and-activity://io.selendroid.testapp.HomeScreenActivity')
        self.assertTrue("and-activity://HomeScreenActivity" in self.driver.current_url)
        my_text_field = self.driver.find_element_by_id('my_text_field')
        my_text_field.send_keys('Hello Selendroid')

        self.assertTrue('Hello Selendroid' in my_text_field.text)

    def tearDown(self):
        self.driver.quit()

if __name__ == '__main__':
    unittest.main()

我的操作系统是archbang，Linux archbang 4.6.4-1-ARCH。

欢迎提出任何建议

编辑

我设法更进一步。看起来像用 app 参数集启动 selendroid，像这样：

java -jar selendroid-standalone-0.17.0-with-dependencies.jar -app selendroid-test-app-0.17.0.apk

并在我的 python 测试脚本中更改所需的功能，如下所示：

desired_capabilities = {'aut': 'io.selendroid.testapp'}

让我更进一步。 我使用 android-sdk 附带的aapt 工具获得了 aut。这是我使用的命令：

./aapt dump badging ~/Desktop/selendroid/selendroid-test-app-0.17.0.apk

现在，我的手机弹出了家庭活动，这是以前没有的。我仍然在 selendroid 服务器中收到错误，同样的错误。

我设法通过切换到不同的操作系统使其正常工作。我切换到基于 ubuntu 的，但我想这没关系。
