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 :

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:
- Working POST Multipart Request with Volley and without HttpEntity
- How to send a “multipart/form-data” POST in Android with Volley
- Trouble Sending Multipart File with Boundary via Volley
Of course, you can find more available in SO.
Hope this helps!
