    copied!<p>Here'e the problem.</p> <p>I have two android phones, both connected to the same wi-fi network. One phone is listening with a ServerSocket and the other attempts to connect with this socket.</p> <p>However, this is not happening. (i.e) The connection does not get established. However, when I create a listening ServerSocket on my PC (also on the same network) and set my phones to connect to the PC, the connection is established.</p> <p>In other words, I am able to create the connection between a phone and PC but not between phone and phone. Does anyone have any idea of what might possibly be causing this problem?</p> <p>Thank you!</p> <p>Below is the code I have used for getting the IPv4 address.</p> <pre><code>WifiManager wifiManager = (WifiManager) getSystemService(WIFI_SERVICE); WifiInfo wifiInfo = wifiManager.getConnectionInfo(); int ipAddress = wifiInfo.getIpAddress(); int[] address = new int[4]; String ip = ""; for (int i = 0; i &lt; 4; i++) { address[i] = ipAddress % 256; ipAddress /= 256; if (i != 3) ip += (String.valueOf(address[i]) + "."); else ip += String.valueOf(address[i]); } return ip; </code></pre> <p>Edit:</p> <p>I tried logging the exact location and cause and it gave the following error:</p> <pre><code>java.net.SocketException: No route to host at org.apache.harmony.luni.platform.OSNetworkSystem.connect(Native Method) at dalvik.system.BlockGuard$WrappedNetworkSystem.connect(BlockGuard.java:357) at org.apache.harmony.luni.net.PlainSocketImpl.connect(PlainSocketImpl.java:207) at org.apache.harmony.luni.net.PlainSocketImpl.connect(PlainSocketImpl.java:186) at java.net.Socket.startupSocket(Socket.java:735) at java.net.Socket.&lt;init&gt;(Socket.java:263) at com.test.word.WifiActivity$12.run(WifiActivity.java:460) at java.lang.Thread.run(Thread.java:1027) </code></pre>
