How to detect Mobile network and WiFi both networks connected current IP address using app.

https://www.android-examples.com/get-display-ip-address-of-android-phone-device-programmatically/

In this tutorial we are getting mobile phone device ip address while phone is connected to Mobile data connection or WiFi connection. This code supports both connection and get ip address from both networks. So here is the complete step by step tutorial for Get/Display IP address of android phone device programmatically.

Please add below all three permissions inside Androidmanifest.xml file.

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