Android Server

[Daniel_Kim]

Hello,

I am a student from UC Berkeley and I was wondering if it was possible to have an android server. And if so, do you have any example code that I can look at?

Thank you very much
Daniel

here is a simple server i made using the basic printer example in the ice manual that displays a notification when a new message is received. Im not sure how to run it on the emulator, because I don't know what host name to give to the client. I just run it on my phone using my wireless home network. Then use the local ip address of the phone as the host name.

Android Server

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Build.VERSION;
import Demo._PrinterDisp;
import Ice.Current;
import android.content.Context;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;

public class helloServer extends Activity {
    /** Called when the activity is first created. */
	Ice.Communicator ic=null;
	Demo.PrinterPrx printer;
	Ice.Object object = new PrinterI();
	
    @Override
    public void onCreate(Bundle savedInstanceState) {
    	if(VERSION.SDK_INT == 8) // android.os.Build.VERSION_CODES.FROYO (8)
        {
            //
            // Workaround for a bug in Android 2.2 (Froyo).
            //
            // See http://code.google.com/p/android/issues/detail?id=9431
            //
            java.lang.System.setProperty("java.net.preferIPv4Stack", "true");
            java.lang.System.setProperty("java.net.preferIPv6Addresses", "false");
        }
        super.onCreate(savedInstanceState);
        if(ic==null){
        Ice.Properties props = Ice.Util.createProperties();
        Ice.InitializationData id = new Ice.InitializationData();
        id.properties=props;
        ic=Ice.Util.initialize(id);
        
        Ice.ObjectAdapter adapter=ic.createObjectAdapterWithEndpoints("SimplePrinterAdapter", "default -p 10000");
        adapter.add(object, ic.stringToIdentity("SimplePrinterAdapter"));
        adapter.activate();
        }

    }
    public class PrinterI extends _PrinterDisp {

	public PrinterI() {
		
		// TODO Auto-generated constructor stub
	}

	@Override
	public void printString(String s, Current __current) {
		// TODO Auto-generated method stub
		NotificationManager notifier = (NotificationManager)helloServer.this.getSystemService(Context.NOTIFICATION_SERVICE);
		Notification notification = new Notification(1,"Notification",System.currentTimeMillis());
		Intent toLaunch = new Intent(helloServer.this,helloServer.class);
		PendingIntent contentIntent =PendingIntent.getActivity(helloServer.this, 0, toLaunch, 0);
		notification.setLatestEventInfo(helloServer.this,s,"" , contentIntent);
		notification.flags |= Notification.FLAG_AUTO_CANCEL;
		notification.flags |= Notification.DEFAULT_SOUND;
		//Send the notification
		notifier.notify(0x007, notification);
	}

}
    
    @Override
    public void onDestroy(){
    	super.onDestroy();
    	//ic.destroy();
    }
    @Override
    public void onPause(){
    	super.onDestroy();
    }

}
