Android上的Kivy：urlopen錯誤[Errno 4]名稱解析中的不可恢復失敗

此Kivy程序適用於我的Windows計算機，但不適用於將其與Buildozer打包並在Android上運行。在Android上它給人的錯誤：Android上的Kivy：urlopen錯誤[Errno 4]名稱解析中的不可恢復失敗

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

這裏是程序：

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

權限來訪問互聯網被授予？（如果我沒有記錯，應該從cmd或buldozer文件中指定） – JustMe

發佈完整的adb日誌。 – inclement

還要確保你的要求中有openssl。這是使用https所必需的。 – inclement

由於@JustMe和@inclement在他們的評論中指出，答案是如此修改buildozer.spec以下兩行存在：

android.permissions = INTERNET
openssl加到requirements線;在我的情況下，它變成了：
requirements = fysom, uuid, dropbox, six, kivy, pytz, requests, openssl
