Retrofit: Image Upload in POST #body - image

Question

After hours goolging and trying different solutions I gave up and I'm asking for some direction, if possible some example. Here is the problem: I have a class that have a picture atribute. I'm using Retrofit and I want to send the Image as part of the Body of HTTP POST and I'm receiving a error. Bellow the code and the error.
Thank you in advance for your help.
The POJO Class:
public class Class1 {
#SerializedName("Picture")
private Bitmap mPicture;
#SerializedName("Giver")
public Integer mGiver;
public String getPicture() {
return mPicture;
}
public void setPicture (Bitmap picture) {
this.mPicture = picture;
}
public String getLaboratory() {
return mLaboratory;
}
public void setLaboratory(String laboratory) {
this.mLaboratory = laboratory;
}
The Activity:
mClass1.setPicture(mImageBitmap);
mClass1DAO.insertClass1(mClass1, new Callback<Integer>() {
#Override
public void success(Integer uid, Response response) {
mClass1.setUID(uid);
progressDialog.dismiss();
Toast.makeText(getApplicationContext(), R.string.msgThankYou, Toast.LENGTH_LONG).show();
dispatchNavigationDrawerActivity();
}
#Override
public void failure(RetrofitError error) {
progressDialog.dismiss();
showErrorDialog(error.getLocalizedMessage());
}
});
The API
#POST("/Service.svc/Insert")
void insert(#Body Class1 class1, Callback<Integer> cb);
The WebService in c#
[OperationContract]
[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Bare, RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json, UriTemplate = "InsertMedicineToDonate")]
Int32 insertMedicineToDonate(MedicineToDonate medicineToDonate);
//insertMedicineToDonate
public Int32 insertMedicineToDonate(MedicineToDonate medicineToDonate)
{
UserService mUserService = new UserService();
if (mUserService.isUserAuthorized())
{
return this.insertMedicineToDonateAuth(medicineToDonate);
}
else
{
errorDetail = new CustomHttpError(003);
throw new WebFaultException<CustomHttpError>(errorDetail, HttpStatusCode.Forbidden);
}
}
Web Service POJO Class
namespace DoarMed
{
[DataContract]
public class MedicineToDonate
{
[DataMember]
public Int32 UID { get; set; }
[DataMember]
public Bitmap Picture { get; set; }
THE ERROR
In the debug when I open the class and look at the attributes all of them are correct but the Picture is wrong.
See the Picture information bellow:
- Picture {System.Drawing.Bitmap} System.Drawing.Bitmap
+ Flags '((System.Drawing.Image)(medicineToDonate.Picture)).Flags' threw an exception of type 'System.ArgumentException' int {System.ArgumentException}
+ FrameDimensionsList '((System.Drawing.Image)(medicineToDonate.Picture)).FrameDimensionsList' threw an exception of type 'System.ArgumentException' System.Guid[] {System.ArgumentException}
+ Height '((System.Drawing.Image)(medicineToDonate.Picture)).Height' threw an exception of type 'System.ArgumentException' int {System.ArgumentException}
and so on
When I try to save the Picture to the DataBase the code throw System.ArgumentException
What am I missing here?
Thank you in advance
