Detect wifi IP address on Android?

Solution 1:

public String getIpAddr() {
   WifiManager wifiManager = (WifiManager) getSystemService(WIFI_SERVICE);
   WifiInfo wifiInfo = wifiManager.getConnectionInfo();
   int ip = wifiInfo.getIpAddress();

   String ipString = String.format(
   "%d.%d.%d.%d",
   (ip & 0xff),
   (ip >> 8 & 0xff),
   (ip >> 16 & 0xff),
   (ip >> 24 & 0xff));

   return ipString;
}

Please Note: You need to add android.permission.INTERNET and android.permission.ACCESS_WIFI_STATE in your AndroidManifest.xml as <user-permission/> to access the code.

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

Solution 2:

Please try this code.

ConnectivityManager connec = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

//To fetch the state of the Wi-Fi network in the device
Boolean isWifi = connec.getNetworkInfo(ConnectivityManager.TYPE_WIFI).isConnectedOrConnecting(); 

WifiManager wifiMgr = (WifiManager) getBaseContext().getSystemService(Context.WIFI_SERVICE); 
WifiInfo wifiInfo = wifiMgr.getConnectionInfo(); 

//To fetch the name of the Wi-Fi network to which the device is connected
String wifiName = wifiInfo.getSSID();
