Is there any Training for "Ice for Android"

uojha

Hi All,

I am trying to learn "Ice for Android". I am able to find trainings for Ice with CPP and Ice with JAVA....

There are IceTrainningCPP.zip and IceTranningJava.zip in the following link ZeroC - Training Courses

But I could not find any training for "Ice for Android".

Is there anyway that I can learn basic things for Ice for Android? The demo examples seems very complicated for the beginners....

Any kind of help is appreciated !

Thanks,
uojha

Hi Upama,

Unfortunately, we do not have a training course for Android at this time.

I'd suggest you go through the 'Ice for Java' training course, which should help a lot. You may also want to watch the 'Ice in 20 minutes' webcast:

Hi Bernard,

I am trying to do a simple application using ICE and Android in which a client side has a button and pressing that button "Test!!!" is printed on server side.

As far as I understood server part cannot be done on android so I wrote server part in java as in the tutorial and modified the client for android.

I am confuse how to make a server.java and client.java inside the same project because server is just in java and client is in android.

I made two different projects test and test1

here is my code for server.java inside test1

public class server extends Ice.Application {
/** Called when the activity is first created.
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
} */
class TestI extends _TestDisp
{

@Override
public void thisTest(Current current) {
// TODO Auto-generated method stub
System.out.println("Test!!!!");
}

}

static public void main(String[] args)
{
server s = new server();
int status = s.main("server", args);
System.exit(status);
}

@Override
public int run(String[] args)
{
// TODO Auto-generated method stub
Ice.ObjectAdapter adapter = communicator().createObjectAdapterWithEndpoints("Test", "tcp -h 127.0.0.1 -p 10000");
adapter.add(new TestI(), communicator().stringToIdentity("Test"));
adapter.activate();
communicator().waitForShutdown();

return 0;
}
}

here is the code for the client.java inside test


import android.app.Activity;
import android.os.Bundle;
import android.view.View.OnClickListener;
import android.widget.Button;

public class client extends Activity
{

Ice.Communicator communicator;
Button sendButton;

public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

sendButton = (Button)findViewById(R.id.send);
sendButton.setOnClickListener(new OnClickListener()
{
public void onClick(android.view.View v)
{
thisTest();
}
});
}

void thisTest()
{
Ice.ObjectPrx obj = communicator.stringToProxy("test:tcp -h 127.0.0.1 -p 10000");
Demo.TestPrx test= Demo.TestPrxHelper.uncheckedCast(obj);
test.thisTest();
}

}


I have a slice file test.ice on both of the project and is as follows

module Demo
{
interface Test
{
void thisTest();
};
};



But I could not run the program its say "unexpectedly stopped"

can you help me understand the problem and organize the project because I am confuse having two different projects, it will be great if I can do it on one project.

Thanks

You can also create servers for Android.

Note that I wouldn't recommend trying to create Android and non-Android applications in the same project. I wouldn't expect that to create a usable non-Android application.

Take care,

Hi Mark,

Thanks for the response and I would love to do the both side on android too.

Is there anyway I can get a small example of Android Client and server(may be program like minimal or Printer) There is a "hello" inside demo but it is very complicated to understand.

This one is very helpful for Java

but I was not able to do the kind of program in Android...

Any suggestions will be a big help

Thanks
