title: Get IP Address of connected Wi fi in Android application
body: <p>When I get the IP Address via the command <code>wifiManager.getIpAddress()</code> the app shuts down. Can someone tell me the reason why ?
  I am obtaining the desired ip  address when I use the method at the bottom, but in the code for the same, when I try displaying the Ip address directly, it gives me an error</p>
  
  <p>EDIT- </p>
