To delete a redirection, you can use the redir del command. Where is either tcp or udp, and and sets the mapping between your own machine and the emulated system, respectively.įor example, the following command sets up a redirection that will handle all incoming TCP connections to your host (development) machine on 127.0.0.1:5000 and will pass them through to the emulated system's 10.0.2.15:6000.: Once connected, use the redir command to work with redirections. Next, connect to the console of the target emulator instance, specifying its console port number, as follows: For example, the console port number for the first emulator instance launched is 5554. You can use the redir console command to set up redirections as needed for an emulator instance.įirst, determine the console port number for the target emulator instance. Setting up Redirections through the Emulator ConsoleĮach emulator instance provides a control console the you can connect to, to issue commands that are specific to that instance. There are two ways to set up network redirections: using emulator console commands and using the ADB tool, as described below. To set up the network redirections, you create a mapping of host and guest ports/addresses on the the emulator instance. Clients can then connect to a specified guest port on the router, while the router directs traffic to/from that port to the emulated device's host port.
To communicate with an emulator instance behind its virtual router, you need to set up network redirections on the virtual router. Currently, the emulator does not support IGMP or multicast. There are no built-in limitations on port numbers or ranges except the one imposed by your host operating system and network.ĭepending on the environment, the emulator may not be able to support other protocols (such as ICMP, used for "ping") might not be supported. The emulator's virtual router should be able to handle all outbound TCP and UDP connections/messages on behalf of the emulated device, provided your development machine's network environment allows it to do so.

On your machine), you should use the special address 10.0.2.2 instead.įinally, note that each emulated device's pre-allocated addresses are specific to the Android emulator and will probably be very different on real devices (which are also very likely to be NAT-ed, i.e., behind a router/firewall) Local Networking LimitationsĮach emulator instance runs behind a virtual router, but unlike an actual device connected to a physical router, the emulated device doesn't have access to a physical network. If you want to access services running on your development machine's loopback interface (a.k.a.

For information about how to let emulator instances communicate over TCP/UDP, see Connecting Emulator Instances.Īlso note that the address 127.0.0.1 on your development machine corresponds to the emulator's own loopback interface. The instances are isolated by a router and can not see each other on the same network. That means that if you have two instances running concurrently on your machine, each will have its own router and, behind that, each will have an IP address of 10.0.2.15. Note that the same address assignments are used by all running emulator instances. The emulated device's own loopback interface The emulated device's own network/ethernet interface Optional second, third and fourth DNS server (if any) Special alias to your host loopback interface (i.e., 127.0.0.1 on your development machine) Addresses within this space are pre-allocated by the emulator/router as follows: The virtual router for each instance manages the 10.0.2/24 network address space - all addresses managed by the router are in the form of 10.0.2., where is a number. Instead, it sees only that it is connected through Ethernet to a router/firewall. An emulated device can not see your development machine or other emulator instances on the network. Network Address SpaceĮach instance of the emulator runs behind a virtual router/firewall service that isolates it from your development machine's network interfaces and settings and from the internet. The sections below introduce the emulator's network architecture and capabilities. The emulator provides versatile networking capabilities that you can use to set up complex modeling and testing environments for your application.
