Installation of Android


This tutorial shows you how to download and install Android SDK to get you started developing Android applications.
The objective of this android  tutorial would be
a) Install the Android SDK on Windows  and configure with eclipse
b) Create an Application that Runs on the Android Emulator
1.Install Java (if it is not on your machine)
Click on Download JDK button
Select Platform and Language for your download and click on license Agreement checkbox  
Click on continue button. Then
Click on jdk-6u23-windows-i586.exe for download
Now save file and install the jdk.
2. Install Eclipse
Eclipse is a professional editor.

If you want to know more then go to  http://developer.android.com/sdk/eclipse-adt.html and read the content Downloading the ADT Plugin

2.2. Android SDK

Download the Android SDK from the Android homepage under Android SDK download . The download contains a zip file which you can extract to any place in your file system, e.g. I placed it under “c:\android” .

2.3. Configuration

In Eclipse open the Preferences dialog via Windows -> Preferences. Select Android and maintain the installation path of the Android SDK. Click Apply, then OK.
Now, set your PATH environment variable by right click on My Computer, and select Properties. Under the Advanced tab, hit the Environment Variables button, and in the dialog that comes up, double-click on Path under System Variables. Add the full path to the tools/ directory to the path, in this case, it is: ;C:\android\android-sdk-windows\tools. Then click OK , OK , OK.
2.4.Create an AVD
In this tutorial, you will run your application in the Android Emulator. Before you can launch the emulator, you must create an Android Virtual Device (AVD). An AVD defines the system image and device settings used by the emulator.
To create an AVD:
In Eclipse, choose Window > Android SDK and AVD Manager.

2.3. Configuration

In Eclipse open the Preferences dialog via Windows -> Preferences. Select Android and maintain the installation path of the Android SDK. Click Apply, then OK.
Now, set your PATH environment variable by right click on My Computer, and select Properties. Under the Advanced tab, hit the Environment Variables button, and in the dialog that comes up, double-click on Path under System Variables. Add the full path to the tools/ directory to the path, in this case, it is: ;C:\android\android-sdk-windows\tools. Then click OK , OK , OK.
2.4.Create an AVD
In this tutorial, you will run your application in the Android Emulator. Before you can launch the emulator, you must create an Android Virtual Device (AVD). An AVD defines the system image and device settings used by the emulator.
To create an AVD:
In Eclipse, choose Window > Android SDK and AVD Manager.
  1. Select Virtual Devices in the left panel.
  2. Click New.
The Create New AVD dialog appears.
3. Type the name of the AVD, such as “testAVD”.
4. Choose a target. The target is the platform (that is, the version of the Android SDK, such as 2.2) you want to run on the emulator.
5. Click Create AVD.  Your new AVD is created now!
Create a New Android Project
After you’ve created an AVD, the next step is to start a new Android project in Eclipse.
  1. From Eclipse, select Select File -> New -> Other…
Click on Android Project and click Next.
2. Fill in the project details with the following values:
  1. Project name: HelloAndroid
  2. Application name: Hello, Android
  3. Package name: com.droidbd.helloandroid (or your own private namespace)
4. Create Activity: HelloAndroid
5.  Min SDK version :        8 (as per API level)
Click Finish.
Run the Application
The Eclipse  plug-in makes it easy to run your applications:
  1. Select Run > Run.
Or Right click on project from project explorer and go
Run as ->Android Application
Yeah, you will see a black screen at your AVD with Your application name and a “Hello …..” text.

EJB - Stateful vs Stateless

For  stateless session beans  the server can maintain a variable amount of instances in a pool. Each time a client requests such a stateless bean (e.g. through a method) a random instance is chosen to serve that request. That means if the client does two subsequent requests it is possible that two different instances of the stateless bean serve the requests. In fact there is no conversational state between the two requests. Also if the client disappears, the stateless bean does not get destroyed and can serve the next request from another client. On the other hand a  stateful session bean  is closely connected to the client. Each instance is created and bounded to a single client and serves only requests from that particular client. So happens that if you do two subsequent requests on a stateful bean, your request will be served always from the same instance of the bean. That means you can maintain a conversational state between the requests. At the end of the li...
