あるデバイスから別のデバイスに小さなパケットを送信しようとしています.私のデバイスのIPはホストである192.168.1.59です.これが私のサーバーコードです.
public class gameServer extends Thread{
/**
* Sets up a server for Android applciation
*/
private static final String TAG = "GameServer";
private DatagramSocket socket;
private int port = 50000;
private InetAddress local = null;
public gameServer( ) throws IOException
{
socket = new DatagramSocket( port );
Log.d(TAG, "Server was setup");
}
private String getLocalIPAddress()
{
try
{
for (Enumeration<NetworkInterface> nis = NetworkInterface.getNetworkInterfaces(); nis.hasMoreElements();)
{
NetworkInterface ni = nis.nextElement();
Log.v(TAG, "NetworkInterface = " + ni.getDisplayName());
for (Enumeration<InetAddress> ips = ni.getInetAddresses(); ips.hasMoreElements();)
{
InetAddress ip = ips.nextElement();
String s = ip.getHostAddress();
Log.v(TAG, "InetAddress = " + s);
if (!ip.isLoopbackAddress())
{
if(InetAddressUtils.isIPv4Address(s)) return s;
}
}
}
}
catch (SocketException e)
{
Log.e(TAG,"getLocalIPAddress()", e);
}
return null;
}
public void passClient( gameObject clientTemp )
{
}
@Override
public void run()
{
Log.d(TAG, "Ip address used:" + getLocalIPAddress() );
while( true )
{
//Send some data
try
{
local = InetAddress.getByName("127.0.0.1");
}
catch (UnknownHostException e2) {
e2.printStackTrace();
}
String msg = "hello there";
int msgLength = msg.length();
byte[] message = msg.getBytes();
DatagramPacket p = new DatagramPacket( message, msgLength, local, port );
try
{
socket.send( p );
}
catch (IOException e2)
{
Log.d(TAG, "Error with sending");
e2.printStackTrace();
}
}
}
}
これが私のクライアントです
public class gameClient extends Thread {

//DELETE!!!
//ONLY FOR TESTING
DatagramSocket socket = null;;
try
{

}
catch (SocketException e1)
{
e1.printStackTrace();
}
byte[] buf = new byte[256];
DatagramPacket packet = new DatagramPacket( buf, buf.length );
try

socket.receive( packet );
}
catch (IOException e)
{
Log.d(TAG, "Error with receiving data");
e.printStackTrace();
}
String data = new String( buf, 0, packet.getLength() );
Log.d(TAG, "Data received was :" + data);
}
}
public void sendTouchEvent(float xSet, float ySet)
{
}
@Override

{

}
コードがパケットを受信しようとすると、socjet.receive( packet ); でクラッシュします。誰でも理由を見ることができますか？
