[ACCEPTED]-how to obtain the ip address of the connected wifi router in android programmatically?-wifimanager
Accepted answer
What you likely want is DhcpInfo:
final WifiManager manager = (WifiManager) super.getSystemService(WIFI_SERVICE);
final DhcpInfo dhcp = manager.getDhcpInfo();
final String address = Formatter.formatIpAddress(dhcp.gateway);
This will yield 2 the (formatted) gateway IP address, which 1 should be what you're looking for.
Since formatIpAddress is Deprecatted, here 1 is the alternative :
public String getHotspotAdress(){
final WifiManager manager = (WifiManager)super.getSystemService(WIFI_SERVICE);
final DhcpInfo dhcp = manager.getDhcpInfo();
int ipAddress = dhcp.gateway;
ipAddress = (ByteOrder.nativeOrder().equals(ByteOrder.LITTLE_ENDIAN)) ?
Integer.reverseBytes(ipAddress) : ipAddress;
byte[] ipAddressByte = BigInteger.valueOf(ipAddress).toByteArray();
try {
InetAddress myAddr = InetAddress.getByAddress(ipAddressByte);
return myAddr.getHostAddress();
} catch (UnknownHostException e) {
// TODO Auto-generated catch block
Log.e("Wifi Class", "Error getting Hotspot IP address ", e);
}
return "null"
}
