create your first android app

In this post i explain how to create your first android application. I use the eclipse ide for the development purpose.
See this article for the installation and configuration of eclipse for android.

Create a new android application project with name HelloWorld. (Click the image to enlarge.)

Now on the activity_main.xml file add a new TextView as shown bellow.

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"  
   xmlns:tools="http://schemas.android.com/tools"  
   android:layout_width="match_parent"  
   android:layout_height="match_parent"  
   android:paddingBottom="@dimen/activity_vertical_margin"  
   android:paddingLeft="@dimen/activity_horizontal_margin"  
   android:paddingRight="@dimen/activity_horizontal_margin"  
   android:paddingTop="@dimen/activity_vertical_margin"  
   tools:context=".MainActivity" >  
   <TextView  
     android:layout_width="match_parent"  
     android:layout_height="wrap_content"  
     android:text="@string/greeting_message"  
     />  
 </RelativeLayout>  

There is no need to make any other changes on the project. Right click the project and select run as android application to run the application.
