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

Question

我试图使用selendroid在浏览器中自动执行一些操作。我设法让服务器启动了。如果我去http://localhost:4444/wd/hub/status，下面是回复

{"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}

显示该设备也被识别。我用的是真正的电话，通过USB连接。一切看起来都很好，但是当我启动测试脚本时，手机启动了应用程序，但是selendroid服务器表明它无法连接。

selendroid的输出如下所示。有更多，但这里是从哪里开始。

如果我让它运行，它只是停留在一个循环中，继续显示错误，可能是试图重新连接。

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

我正在运行的测试脚本是用python编写的。下面是：

#!/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 4.6.4-1-ARCH.

如有任何建议请见谅。

编辑

我又走了一步。看起来像使用app参数集启动selendroid，如下所示：

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

并在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。我用的是aapt工具，这是与android配套的。下面是我使用的命令：

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

现在，我的手机--家庭活动--突然出现了，这是以前没有过的。但是，我仍然在收到selendroid服务器中的错误，同样的错误。

Answer 1

通过切换到不同的操作系统，我设法让它正常工作。我换了一个基于ubuntu的，但我想这并不重要。
