I just found the solution to run Andy Chat in Eclipse. Follow the steps below:
Step 1: Import the AndyChat package in Eclipse [You can download the AndyChat package form here=>https://www.box.com/shared/130ph7fsbgrj1h69pksq ]
Step 2: Open "src" folder in eclipse like this.
Step 3: Drag and Drop "ChatServer.java" to "src" folder.
A new package named "(default package)" will be created along with "ChatServer.java" file.
Step 4: Now delete the "ChatServer.java" file in "edu.UTEP.android".
Step 5: Now goto Command Prompt and run the "ChatServer.java" file. This will start the Chat Server which will receive the message.
Step 6: Now Run the AndyChat application in emulator. The application in the emulator will act as a Client. Type some message in the TextBox and click Send button. Bingo!!! The message will appear in the Command Prompt.
