How are you calling the web service? Do you encode the whole file into a string and pass it as a HTTP GET parameter? — Axarydax, Mar 13 '14 at 07:09

The simplest way is convert your bitmap to base64 string :

public String encodeTobase64(Bitmap image)
{
    Bitmap immagex=image;
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    immagex.compress(Bitmap.CompressFormat.JPEG, 100, baos);
    byte[] b = baos.toByteArray();
    String imageEncoded = Base64.encodeToString(b, Base64.DEFAULT);

    return imageEncoded;
}

after converting ,you can send the string to webservice, on the server side, you must decode this string to an image ! To convert base64 to image on server side,duckduckgo or google will help you :

Have a look at this tutorial by Microsoft - you'll be able to use the Build the Web Service part for the web service.

For the Android part, you can get inspired by all other questions that try to send a POST request - for example this one.

If not too late, here is my suggested solution:

Server side: you can create a web service or RESTful application on the .NET Framework. Microsoft provides ASP.NET Web API. You can start from their website here
Client side: your Android here. You can refer to some of the following: Volley, Retrofit...

If you want to use Volley, you can refer to some following links:

Of course, you can find more available in SO.

Hope this helps!
