Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
Example one
The invention is based on IP address conflict detection in android equipment, namely, aiming at equipment provided with an android system, the conflict detection of the allocated IP address is added in the process of allocating the IP address in the existing android system accessed to the Ethernet or a wireless network, whether the allocated IP address conflicts or not is detected, and when the IP address conflicts, a prompt can be sent to a user in time, so that the user can know the IP address faults in time, and the network fault can be checked.
As shown in fig. 1, the present invention provides a preferred embodiment, and an IP collision detection method based on an android system, including the following steps:
and step S1, starting the system and detecting whether the network state of the system changes in real time.
Preferably, whether the network state of the system changes is monitored by monitoring network monitoring broadcasts in the system.
That is, when the system is started, each network monitoring broadcast in the system is monitored in real time, and when the broadcast callback function of the corresponding network monitoring broadcast is executed, the network state of the system is considered to be changed. In this embodiment, the network accessed by the system is an ethernet network, a wireless network, or the like.
The network monitoring broadcast is a network monitoring broadcast carried by the android system. When the network of the android system changes, the corresponding broadcast callback function of the network monitoring broadcast is executed. And judging whether the network state of the system changes or not by detecting the network monitoring broadcast in real time. The network monitoring broadcast in the android system comprises a plurality of network monitoring broadcasts, specifically:
android.net.ethernet.ETHERNET_STATE_CHANGED，
android.net.ethernet.STATE_CHANGE，
android.net.conn.CONNECTIVITY_CHANGE，
android.net.wifi.WIFI_STATE_CHANGED，
android.net.wifi.STATE_CHANGE，
network _ STATE _ CHANGED _ ACTION.
Step S2, when the network status of the system changes, acquiring the current network and acquiring the IP address broadcast signal of the current network.
Preferably, the current network is obtained according to the type of the network listening broadcast.
And step S3, obtaining IP address information according to the IP address broadcast signal of the current network.
And step S4, performing conflict detection on the IP address of the current network according to the arping command and the IP address information, and if the conflict exists, executing step S5.
And step S5, prompting the user that the IP address conflict exists in the current network.
Preferably, the message prompt may be popped up through a pop-up box prompt or in a status bar.
That is, when there is no conflict in the IP address, the device can normally access the network and continue other operations; when the IP address conflicts, the user is prompted that the IP address conflicts exist in the current network, and the user is informed in time.
Preferably, in step S4, it is determined whether there is an IP address conflict in the current network according to the execution result of the arping command.
The arping command is to broadcast the arp packets outwards by a local computer, so that all hosts in the same local area network receive the arp packets; meanwhile, the local computer does not make any Reply when receiving the arp packets, and other hosts in the local area network can Reply and return to the local computer after receiving the arp packets. Wherein, the Reply operation refers to the network message response, and is the specific content in the arping command.
When the IP address is not occupied by other hosts in the local area network, the execution result of the arping command is null; when an IP address is occupied by other hosts of the local area network, the execution result of the arping command is 1, and the MAC address of the host binding the IP address is returned.
According to the invention, the IP conflict detection command is embedded into the android system, and after the access network of the android system changes, the conflict detection is carried out on the IP address allocated by the current network, so that when the IP address conflicts exist, a user is timely reminded, and the difficulty and cost of network troubleshooting are further reduced.
