Hello to the Android World!

This is my first post on my new blog "Android for Beginners". The reason behind creating this blog is to help the beginners in the android development. I have just started learning Android and know what the problems beginners face. 
Here is my first post: Say "Hello to the Android World!"

Before getting into the details, first we will create a simple application to say Hello World!. This is just a simple introductory example in which we will create and run one application. (We will get into the details in the up coming posts.)

A. Installation (Windows):
1. Install Java Development Kit. 
2. Download the Android SDK. (http://developer.android.com/sdk/index.html)
3. Unzip the downloaded file. There two folders namely eclipse and sdk and one file namely SDK Manager.
4. Open the eclipse folder. Double click on the eclipse.exe file. Select the required workspace or if you want keep the default one. 

You will see the window similar as below:

 
B. Application Development:
1. Go File --> New --> Android Application Development.

Give the proper values for the Application Name, Project Name, Package Name. Set the minimum required SDK, Target SDK, Compile with and Theme as stated in the above image. Always set the target SDK to the latest available.

 2. Click Next.

 Browse the location where you want to save the project.

3. Click Next.

Here you can set the launcher icon. You can select an Image from your machine or you can create your own icon.

4. Click Next.

Here you will specify the activity. This time select the Blank Activity.

5. Click Next.

 

Specify the Activity Name i.e. the Java class, Layout Name i.e XML file and Navigation Type to None. Click Finish.

The above mentioned window is displayed because we haven't specified the compatible target yet. To do this click No. You will be prompted with the following window:

Close the Window.
Go to Window --> Android Virtual Device Manager.

 Click New.

Specify the details as mentioned in the above mentioned image. You can specify whatever name you want in the AVD Name. Click OK. It will take some time to set.

Close the window.
Again go to Package Explorer. Right click on your project. Go to Run  As --> Run Configurations...

Go to Android Application --> HelloWorldApp --> Target --> Select Automatically pick compatible device: Always uses preferred AVD if set below, launches on compatible device/AVD otherwise.
Select AVD_1 --> Click Apply -- Click Run.

Your application will run in the emulator:
