Whoever getting started to learn Web services - Android app interaction I hope this tutorial may be helpful, You can download the full source from here: https://github.com/harshadura/RDA-Android-ASP.WS-interact/archive/master.zip

Prerequisites: 
.NET framework, SQL server 2008, Android device/emulator
 
How to run.

1. Attach the MDF file into your SQL server.
2. Change the connection string at the C# project config according to your db connection.
3. Change the 'Web service URL' on the Android Application.

1. You will need to use WIFI tether to get connect your device with PC/otherwise you will need a router, both connected into it.
2. Sometimes you will need to configure the security restrictions of your IIS web server to get connect the device.

            {
                Console.WriteLine(e.Message);
            }
        return employees.ToArray();
    }
}

  envelope.setOutputSoapObject(request);
  HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
  try {

  }

  result = (SoapObject) envelope.bodyIn;
  
 }

Finally i was able to blink a LED on my Arduino through an Android app. Well! it was a really glad moment for me. :-D

 

Tether your phone to your computer.
You will find the option to create a "portable WiFi hotspot". This will be in the options, under "wireless connections" "internet" or "tethering" (it depends on what version of android you have). Once you have turned on the hotspot (you can use the default name and no password, or press "settings" to configure it), you connect to your phone from your PC as you would to any other hotspot.
EDIT: If your phone cannot make a hotspot (it seems the HTC Hero cannot) you have two options:
1) if your phone is rooted, install WiFiTether (code.google.com/p/android-wifi-tether/)
2) if you are running Windows Vista/7, install Connectify (connectify.me) to turn your PC into a hotspot, and then connect to it with your phone. You will find the phone's IP in Connectify's list of connected clients.
Once you're connected, make sure to set your firewall to allow connections to and from other computers in the network (I don't know how to use your firewall, but if you're running Windows Vista or 7, make sure to set it as a "home" network).
And you're done. Your phone's IP address can be found by going to "network connections" (in network & sharing centre in Vista & 7) and looking at the status of the WiFi adaptor. It will be the IP address labelled "default gateway".

Few Notes
------------------------------------
* You can use this[1] UCSC converter to convert unicode font into ttf related codes which are using in the xml view.

ex: "wessa" > jeiai
"jeiai" is the text you have to put into xml, that will result in "wessa" as output.

[1] http://www.ucsc.cmb.ac.lk/ltrl/services/feconverter/?maps=s_dlm-u.xml

* You can use any Sinhala unicode supported font instead of using "amal.ttf" font. (in case if you dont like that font style)
* No need of Tamil fonts cause Tamil unicode is already consist with Android. (South indians developers might rocking huh!)

Cheers! happy localizings!

This is an amazing news for the Android users because now you can capturing screenshots & record video of Android Phones very easily. I found this article on technospot.net. So thanks for sharing this steps. And they have tested on Motorola Milestone an Android based smartphone. You can also try it on your Android powered device. So check this out bellow.

• Download and install Java SE Development Kit (JDK)
• Download Android SDK for Windows Platform
• Extract Android SDK, run the SDKManager.exe, it will open a window titled as ‘Choose Packages to Install’, Cancel it, and click on the ‘Available Packages’ from left panel on the window titled as ‘Android SDK and AVD Manager’, there select the ‘USB Driver package’ and install it.

• Go to the folder where you extracted the Android SDK, there run the ddms.bat, this can be found in the ‘Tools’ folder.
• Running ddms will launch the ‘Dalvik Debug Monitor’; make sure your device is being displayed there under the list, select your device by clicking on it.

• Now click on the ‘Device’ tab, to get the ‘Screen Capture’ option.

• Apart from other functionalities provided by the Dalvik Debug Monitor, it allows you a full screen view.
• It dynamically changes the view, by showing you current screen, which means you can use it for Screen Casting as well, have a look.

SUBSYSTEM=="usb", SYSFS{idVendor}=="04E8", MODE="0666"

If you are like me and like developing in Linux, then you will find this guide useful. When I was setting up everything for my Android development, I ran into the problem that Linux was not recognizing my Android phone, and took me some time figuring out how to make Linux recognize my phone. Finally, after some research I was able to put this little guide together and decided to share it with the rest of the world.
ADB (Android Debug Bridge) is a handy tool that comes with Android SDK that allows you to control and interface with your Android device.

Update: 02/04/11 – HTC changed its Vendor ID, older phones have different ID than newer phones. Refer to USB Vendor IDs table at the bottom of this tutorial to see the change.
Update: 01/02/11 – By mistake I had linked the ADB tool for OSX in step 3.1. Now it should be the correct one for Linux.
IMPORTANT Update 12/11/10 – There has been a change to the new Android SDK. ADB Tool has been moved to /android-sdk-linux_x86/plataform-tools, so if you have the old SDK, please download the new one and update your path (Step 9.2 of this tutorial). If this is your first time doing this, then disregard the update and continue with the tutorial.
Update: 09/21/10 – Working code with Ubuntu Lucid Lynx and added more USB vendor IDs.

1. Download the latest Android SDK from Google: Android SDK
2. Extract the TGZ file to your home/YOUR-USERNAME directory
3. To get ADB, you need to install the SDK: Installing the SDK
   • If you are not a developer and not planning to develop, then just download the following zip file containing only the ADB tool and proceed with the tutorial: ADB
4. On your phone, click Settings > Applications > Development and make sure USB Debugging is on.
5. Login as root and create this file: /etc/udev/rules.d/##-android.rules
   NOTE: In the above file replace ## with the number 50 if you are running Gusty/Hardy/Dapper (50-android.rules) or with the number 70 if you are running Karmic Koala/Lucid Lynx/Maverick Meerkat(70-android.rules)
   • Or simply type in terminal sudo gedit /etc/udev/rules.d/##-android.rules then enter your password
6. The file should read:
   • For Gusty/Hardy: SUBSYSTEM==”usb”, SYSFS{idVendor}==”0bb4″, MODE=”0666″
   • For Dapper: SUBSYSTEM==”usb_device”, SYSFS{idVendor}==”0bb4″, MODE=”0666″
   • For Karmic Koala: SUBSYSTEM==”usb”, SYSFS{idVendor}==”0bb4″, MODE=”0666″
   • For Lucid Lynx: SUBSYSTEM==”usb”, SYSFS{idVendor}==”0bb4″, MODE=”0666″
   • For Maverick Meerkat: SUBSYSTEM==”usb”, ATTR{idVendor}==”0bb4″, MODE=”0666″
   NOTE: In the above lines the code ”0bb4″ refers to a HTC device. If your phone is from a different manufacturer, replace the code with the appropriate from the table below.
   NOTE: If you copy one of the lines mentioned above, make sure you replace the quotation marks with the ones in your keyboard, as these have different display code and it might give you a “no permissions” error.
7. Execute: sudo chmod a+rx /etc/udev/rules.d/70-android.rules
8. Reboot
9. To run ADB you need to add an environment variable to your bashrc file:
   • Open a terminal window and type: sudo gedit .bashrc
   • Add the following line at the end: export PATH=${PATH}:/home/YOUR-USERNAME/android-sdk-linux_x86/platform-tools
   • Save and close
10. You should be ready to go, type adb devices in a terminal window with your phone plugged in.
    If you see a serial number pop up that means you are done. Should look something like this:
    List of devices attached
    HT99PHF02521 device
