Can't get messages from publisher on Android
Hi, I'm using the code from the android_tutorial_pubsub on android studio and for some reason, after getting a topic on Ubuntu publishing messages, I can't get them on android even though I succeeded while trying to connect the app to the MASTER URI.
Here's the code:
import android.os.Bundle;
import android.util.Log;
import org.ros.address.InetAddressFactory;
import org.ros.android.MessageCallable;
import org.ros.android.RosActivity;
import org.ros.android.view.RosTextView;
import org.ros.node.NodeConfiguration;
import org.ros.node.NodeMainExecutor;
public class MainActivity extends RosActivity {
private RosTextView<std_msgs.String> rosTextView;
public MainActivity() {
super("Pubsub Tutorial", "Pubsub Tutorial");
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
rosTextView = (RosTextView<std_msgs.String>) findViewById(R.id.text);
rosTextView.setTopicName("test");
rosTextView.setMessageType(std_msgs.String._TYPE);
rosTextView.setMessageToStringCallable(new MessageCallable<String, std_msgs.String>() {
@Override
public String call(std_msgs.String message) {
return "MSG: " + message.getData();
}
});
}
@Override
protected void init(NodeMainExecutor nodeMainExecutor) {
NodeConfiguration nodeConfiguration = NodeConfiguration.newPublic(getRosHostname());
nodeConfiguration.setMasterUri(getMasterUri());
nodeConfiguration.setNodeName("test");
nodeMainExecutor.execute(rosTextView, nodeConfiguration);
}
}
I'm using VMWare player to run the /test topic and I'm using a SSH tunnel to connect my phone to it, which has worked in the past in tutorials like controlling the turtle from TurtleSim.
What am I missing? Thanks in advance.
