我已经阅读并尝试了kivy buildozer android https request fail的解决方案，但Python 3可能会改变一些事情吗？
我正在尝试运行UrlRequest;当我在笔记本电脑上使用python main.py运行它时，它运行得很好，但当我尝试在Android设备上运行它时，我一直看到日志行

11-14 10:12:14.202  6785  6939 I python  : [INFO   ] REQ   ERROR -- <UrlRequestUrllib(Thread-1, started daemon 517489732944)> <<[Errno 7] No address associated with hostname>>

字符串
如果我将UrlRequest更改为UrlRequestRequests，并将必要的wod添加到buildozer.spec文件中，我反而得到了更长但不是特别信息化的文本。

11-14 10:21:32.098  7626  7719 I python  : [INFO   ] [REQ   ERROR -- <UrlRequestRequests(Thread-1, started daemon 517496282448)> <<HTTPSConnectionPool(host='www.google.com', port=443)] Max retries exceeded with url: / (Caused by NameResolutionError("<urllib3.connection.HTTPSConnection object at 0x787e579ba0>: Failed to resolve 'www.google.com' ([Errno 7] No address associated with hostname)"))>>

我已经按照https://buildozer.readthedocs.io/en/latest/installation.html上的buildozer安装说明进行了安装（包括先安装libssl-dev，然后再安装buildozer android clean）。
最小可再现误差为：

# main.py

kivy.require('2.2.1') # replace with your current kivy version !

        lbl = Label(text="Placeholder Text")
        def _setlbl(new_text):
            Logger.info("REQ   callback started. Setting label text...")
            lbl.text = new_text
            Logger.info("REQ   text set")
            return new_text

我做错了什么？
编辑：
添加运行时权限请求本身并不能解决问题。

from kivy.utils import platform

Logger.info(f"PLATFORM {kivy.utils.platform}")

到main.py之间的现有导入和HelloApp声明，我可以看到每个单独的日志行命中终端，但它仍然导致请求错误。

除了spec文件中的permissions，你还需要在你的python代码中包含一个运行时权限请求，类似于这样：

from android.permissions import request_permissions, Permission
request_permissions([Permission.INTERNET])

字符串
请参阅文档。下面是我使用的一个示例：

from kivy.utils import platform
if platform == 'android':
    perms = ['android.permission.INTERNET']
    from android.permissions import request_permissions
    request_permissions(perms, None)

型
你可以把它放在main.py的开头，它不需要在任何类中。
