What do you want to know? My knowledge of Android is still cursory, but I've been developing something for the platform since I'd like to get into mobile development. Android platforms also have a pretty liberal structure when it comes to getting software on their platform as well, so that gives me a better shot.

Well, im new with Android programming still. But im asking myself, i know that u can run program(app) in background (@service) of phone sistem, but can you run 2 apps in background witch
witch are connected but they do a different job? I mean, can u programm them to work that way, and is there some tutorial about it :)

I haven't tried it, but it sounds like it can be done since Android is able to run more than one program. I don't know of any example though.

I would say yes, but... could lead to "poor battery life" and/or lack of memory.

Hi all, i just started looking at the adroid and java, all my knowledge is in C++ and C#. so i'm brand new to java and android but they are a derevitive of C some it's the next thing for me to learn.

Anyway to the point, i've just done the whole Hello World thing, but i'm not sure it working.
i follow the tutorial on Hello, World | Android Developers

this is all the program is :

package com.example.helloandroid;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;


public class HelloAndroid extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        //added by tutorial
        TextView tv = new TextView(this);
        tv.setText("Hello, Android ");
        setContentView(tv);

    }
}

but in the AVD all i got is:
[ATTACH=CONFIG]3728[/ATTACH]

which looks nothing like the tutorial and seems to not have the text i want.

any ideas on what i done wrong

thanks for ya time

Supposedly the emulator takes a LONG time to load on first boot. Wait for a few minutes and see what happens.

it took 15 minutes, but ya were right, thankz. i've gone futher into the tutorials but it all xml. but very little advanced topics. AS a Games Programmer i was wondering if there was a place with higher end tutorials dealing with location render controls and how it handles class hirachacal things like ploymorphism if abstratation is possaible and under what terms.

basiclly and all android progrsmming techniques and differance from normal C or C#

I started with this : Android 3D game tutorial – Part I on Android Development

It lunched me to a right path, so I hope it will work for u 2 :)

I'm a full time Android dev.

To answer your question, yes, you can run two services in the background but be careful with battery life and also, services might get killed by Android to reclaim memory (they get killed fairly often on low memory phones).

I'll throw this out there about the AVD - I never use it. Seriously. I know a lot of people do, but I prefer hands on, right there on my phone. Faster load time too. Then again, I write tools that modify the system so.... kinda have to do it on real phone lol
