Android上的Kivy：urlopen错误[Errno 4]名称解析中无法恢复的失败

时间：2016-05-12 21:53:14

标签： android python kivy

这个Kivy程序可以在我的Windows计算机上运行，​​但不是在我用buildozer打包并在Android上运行时。在Android上它给出错误：

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

以下是该计划：

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

1 个答案:

答案 0 :(得分：1)

正如@JustMe和@inclement在评论中指出的那样，答案是修改buildozer.spec所以存在以下两行：

  • android.permissions = INTERNET

  • openssl已添加到requirements行;在我的情况下它变成：
    requirements = fysom, uuid, dropbox, six, kivy, pytz, requests, openssl
