Rosjava InetAddress failure [closed]
Hi, I have been attempting to use rosjava with android 3.1 with no success. I was following some of the examples, but I get an unexpected failure in the InetAddress. The message is: "Could not find method com.google.common.net.InetAddresses.isInetAddress, reference from method org.ros.address.InetAddressFactory.newFromHostString". My code is very simple. Here it is:
package org.blh.android;
import android.app.Activity;
import java.net.InetAddress;
import java.net.URI;
import java.net.URISyntaxException;
import org.ros.address.InetAddressFactory;
import org.ros.internal.node.DefaultNodeFactory;
import org.ros.node.Node;
import org.ros.node.NodeConfiguration;
import org.ros.node.DefaultNodeRunner;
import android.os.Bundle;
import android.widget.Toast;
public class TestRosActivity extends Activity {
String ip = "10.0.0.8";
String masterUri = "http://" + ip + ":11311/";
URI uri = null;
String host = null;
NodeConfiguration nodeconfiguration = null;
String defaultNodeName = "my_node";
DefaultNodeFactory factory = null;
Node node = null;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
String dump = "";
try
{
uri = new URI(masterUri);
InetAddress inet = InetAddressFactory.newNonLoopback();
dump += "1,";
if (inet != null)
{
host = inet.getHostName();
dump += "2,";
nodeconfiguration = NodeConfiguration.newPublic(host, uri);
dump += "3,";
factory = new DefaultNodeFactory();
dump += "4,";
node = factory.newNode(nodeconfiguration);
dump += "5,";
}
}
catch (Exception e)
{
Toast t = Toast.makeText(getApplicationContext(), "Exception: " + e.getMessage() + ". " + dump, Toast.LENGTH_LONG);
t.show();
}
}
}
I am pretty new to ros, so hopefully it isn't a stupid mistake on my part. I didn't forget to add the internet permission. I have tried this on the emulator (2.3.3) and on my tablet (3.1).
Thanks for your help.
