我在我的 android 应用程序中遇到了 http post 请求的问题：
libcore.io.ErrnoException: socket failed: EACCES (Permission denied)
我的应用程序在大多数 Android 设备上运行良好，除了一部 android 手机，我的应用程序无法通过该手机上的 http 连接到互联网。但其他应用程序可以在该安卓手机上运行良好，例如浏览器。
我发现有一些关于的问题EACCES (Permission denied)，我在我的应用程序中检查了<uses-permission android:name="android.permission.INTERNET" />权限，没有问题。
