Error message: the socket with no operation permission cannot be connected to the outside world, and the error is not reported. The exception can be seen in logcat and the above exception is thrown. If your program wants to connect to the Internet, it will throw this exception and eventually fail to connect to the Internet. The reason is: You must have the permission to access the network. Solution: In androidmanifest. <uses-Permission Android: Name = "android. permission. internet "/> (note that the location is the next level of the <manifest> node). Therefore, permission verification is strict for Android, and permission configuration is required for many operations ..
