4 Creating A First Android Application ("Hello, Android")

This example is taken from http://code.google.com/android/intro/hello-android.html. It's a good test if your Android SDK is working as expected. We will create a small application that displays Hello, Android on an Android phone.

First, we create a new project (File > New > Project...):

Select Android Project and click on Next >:

Fill out the project details as follows:

Afterwards, you should see this window (navigate to HelloAndroid > src > com.android.hello > HelloAndroid.java > HelloAndroid > onCreate(Bundle) to see the source code in the source code window). Click on the Maximize icon in the upper right corner of the source code window to maximize it:

You should then see the source code in a bigger window. Modify the code so that it looks as follows:

package com.android.hello;

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);
       TextView tv = new TextView(this);
       tv.setText("Hello, Android");
       setContentView(tv);
   }
}

Save the file. To run the code, go to Run > Run Configurations...:

Highlight Android Application and click on the icon in the upper left corner that looks like a white sheet of paper:

The following window should come up. Fill it out as shown, click on Apply...

... and then on Run:

When you do this for the first time, the following message appears. Click on Proceed to continue:

Finally, the Android emulator comes up. It can take a while until the Android phone has started up (so please be patient), but afterwards you should see Hello, Android in the display:

Congratulations, everything is working as expected!

You do not need Eclipse
Submitted by rio (not registered) on Sun, 2009-04-12 08:22.

You do not need eclipse to install and develop android Application...

 Eclipse plugin is just wrapper to command line...

Take a look at my tutorial:

The instructions are perfect...I  have installed on ubuntu 8.10 (and all it's the same)

Testing the emulator on a centrino 1.5G it's slow (but you can see android without having to buy a phone)

Submitted by Benny Iskandar (not registered) on Sun, 2009-01-11 01:34.

Hi, I've just following steps , but it failed when performing the "Running project" action. The handset display emulator only display the text below : "Android _" .  But there is nothing happen after then . Please see the eclipse console displays the log below :

[2009-01-11 08:17:31 - Emulator] emulator: warning: opening audio output failed

[2009-01-11 08:17:31 - Emulator] [2009-01-11 08:17:31 - HelloAndroid] New emulator found: emulator-5554

[2009-01-11 08:17:31 - HelloAndroid] Waiting for HOME ('android.process.acore') to be launched...

[2009-01-11 08:17:34 - Emulator] emulator: emulator window was out of view and was recentred

[2009-01-11 08:17:34 - Emulator]

Is it because the audio output failed, so i can not continue the work ? And anybody can help me to this problem ? Thanks and need your help , please .

Nice article!

Great article, thanks! Just a quick FYI in case anyone else has the same problem I had (I've seen other posts on other forums about it now).

If the URL for the ADT Eclipse plugin repository doesn't work (
https://dl-ssl.google.com/android/eclipse/) try it without the https, and just http (
http://dl-ssl.google.com/android/eclipse/). That worked for me (secure version kept complaining there was no repository there).
