android - Android 上的 Kivy : urlopen error [Errno 4] non-recoverable failure in name resolution

Question

这个 Kivy 程序可以在我的 Windows 计算机上运行，​​但当我用 buildozer 打包它并在 Android 上运行时就不行了。在 Android 上它给出错误:

I/python  ( 2173): <urlopen error [Errno 4] non-recoverable failure in name resolution.>

程序如下:

from kivy.app import App
from kivy.uix.label import Label
import json

try:
    # For Python 3.x
    from urllib.request import urlopen
except ImportError:
    # Fall back to Python 2's urllib2
    from urllib2 import urlopen

SETTINGS_URL = ('https://raw.githubusercontent.com/'
                'SpotterRF/jekyll-updater/master/package.json')


class MyApp(App):

    def build(self):
        response = urlopen(SETTINGS_URL)
        file_bytes = response.read()
        file_string = file_bytes.decode('utf-8')
        settings_dict = json.loads(file_string)

        return Label(text=settings_dict["name"])


MyApp().run()

buildozer.spec 有 requirements = fysom, uuid, dropbox, six, kivy, pytz, requests

Answer 1

正如@JustMe 和@inclement 在他们的评论中指出的那样，答案是修改 buildozer.spec 以便出现以下两行:

• android.permissions = INTERNET

• openssl 添加到 requirements 行；在我的例子中，它变成了:
  requirements = fysom、uuid、dropbox、six、kivy、pytz、requests、openssl
