Technical Field

The invention belongs to the technical field of Android system application, and particularly relates to an Ethernet sharing method based on an Android system.

Background

Many android industrial control devices on the market contain ethernet ports, and after a large number of users purchase the industrial control devices, other devices need to use the ethernet ports to realize the requirement of external network access, such as a network camera. In order to facilitate users and reduce unnecessary wired networking and additional expenses, a 4G routing device that can be used in an open environment is urgently needed.

In the Android native system, a function called a portable WLAN hotspot is provided, and the function can configure the Android mobile phone into an AP hotspot and is similar to a function of a simplified version 4G router. After the network is started, the 4G at the moment is called as a source network, and the WIFI is called as a shared network. However, it has the following disadvantages: (1) an Ethernet port cannot be configured to realize Ethernet sharing for a sharing network; (2) no source network can be specified (only the system's own default source network can be used); (3) the network segment and DNS of the subnet cannot be configured; (4) the connection state and information of all the sub-network devices connected to the shared network cannot be monitored and checked; (5) no API interface is provided to control the turning on and off of the network sharing function.
