I. OverviewI am used to network programming in Linux. I have been wondering how to get the IP address of my mobile phone before I use a smartphone ). Okay, I know that Android is based on the Linux kernel. Can I use the network programming method in Linux I learned to get the IP address? In fact, this is a relatively low-level method. on

When we learn and use the Android network programming, we touch only the upper layer protocols and interfaces such as Apache HttpClient or Android's own httpurlconnection and so on. We also need to learn more about the underlying implementations of these interfaces, which requires that we understand the network communication layer and that the network communication layer has to speak of the Iso-osi seven-layer protocol classic architecture:The left pa

. So the traceroute just fills this flaw.The principle of traceroute is very very interesting, it receives the IP of the destination host, first sends a ttl=1 to the destination host (remember what TTL is?). UDP (the next to know what UDP is the packet), and after the first router receives the packet, the TTL is automatically reduced by 1, and the TTL becomes 0, the router will discard the packet, and at the same time produce a host unreachable ICMP d

As long as you can find the system in the virtual machine through the IP address, you can do a lot of things, such as:ADB debugging, or using NC commands to transfer some files or folders, etc...The following is an example of debugging android-x86 in the ADB connection VirtualBox:Installing Android-x86First of all you have to install the
