I want to get the currently running Android Emulator's IP address through code. How can it be achieved?
Just to clarify: from within your app, you can simply refer to the emulator as 'localhost' or 127.0.0.1.
Web traffic is routed through your development machine, so the emulator's external IP is whatever IP has been assigned to that machine by your provider. The development machine can always be reached from your device at 10.0.2.2.
Since you were asking only about the emulator's IP, what is it you're trying to do?
Use this method you will be getting 100% correct ip address for your android emulator
To get the ip address of yoor emulator
Go to adb shell and type this command
adb shell
ifconfig eth0
After running this command I am getting
IP : 10.0.2.15
Mask : 255.255.255.0
Which works for me . I am also working for an networking application.
If you do truly want the IP assigned to your emulator:
adb shell
ifconfig eth0
Which will give you something like:
eth0: ip 10.0.2.15 mask 255.255.255.0 flags [up broadcast running multicast]
If you need to refer to your host computer's localhost, such as when you want the emulator client to contact a server running on the same host, use the alias 10.0.2.2 to refer to the host computer's loopback interface. From the emulator's perspective, localhost (127.0.0.1) refers to its own loopback interface.More details: http://developer.android.com/guide/faq/commontasks.html#localhostalias
Like this:
public String getLocalIpAddress() {
try {
for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
NetworkInterface intf = en.nextElement();
for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
InetAddress inetAddress = enumIpAddr.nextElement();
if (!inetAddress.isLoopbackAddress()) {
return inetAddress.getHostAddress().toString();
}
}
}
} catch (SocketException ex) {
Log.e(LOG_TAG, ex.toString());
}
return null;
}
Check the docs for more info: NetworkInterface.
Within the code of my app I can get the running device IP andress easily like beolow:
WifiManager wm = (WifiManager) getSystemService(WIFI_SERVICE);
String ip = Formatter.formatIpAddress(wm.getConnectionInfo().getIpAddress());
public String getLocalIpAddress() {
try {
for (Enumeration < NetworkInterface > en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
NetworkInterface intf = en.nextElement();
for (Enumeration < InetAddress > enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
InetAddress inetAddress = enumIpAddr.nextElement();
if (!inetAddress.isLoopbackAddress()) {
return inetAddress.getHostAddress().toString();
}
}
}
} catch (SocketException ex) {
Log.e(LOG_TAG, ex.toString());
}
return null;
}
