    <p>I am pretty new to both Android and WCF. I am making a user table with a very small image in the sql server db as varbinary. In my service I have the following OperationContract:</p> <pre><code> [OperationContract] [WebGet(UriTemplate = "users/{emailAddress}/Image", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare)] System.IO.Stream GetImage(string emailAddress); </code></pre> <p>Implementation:</p> <pre><code> public System.IO.Stream GetImage(string emailAddress) { //parse personID, call DB string query = "Select profilePic from Flows_Users WHERE emailAddress= @emailAddress"; SqlConnection objConnection = new SqlConnection(); DataSet ObjDataset = new DataSet(); SqlDataAdapter objAdapater = new SqlDataAdapter(); SqlCommand objCommand = new SqlCommand(query, objConnection); objCommand.Parameters.Add("emailAddress", SqlDbType.NVarChar).Value = emailAddress; objConnection.ConnectionString = ConfigurationManager.ConnectionStrings["ConnStr"].ToString(); objConnection.Open(); byte[] pic = (byte[])objCommand.ExecuteScalar(); objConnection.Close(); // if (pic == null) // return null; OutgoingWebResponseContext context = WebOperationContext.Current.OutgoingResponse; // //if (image_not_found_in_DB) // //{ // // context.StatusCode = System.Net.HttpStatusCode.Redirect; // // context.Headers.Add(System.Net.HttpResponseHeader.Location, url_of_a_default_image); // // return null; // //} //// everything is OK, so send image context.Headers.Add(System.Net.HttpResponseHeader.CacheControl, "public"); context.ContentType = "image/jpeg"; // context.LastModified = date_image_was_stored_in_database; context.StatusCode = System.Net.HttpStatusCode.OK; return new System.IO.MemoryStream(pic); } </code></pre> <p>Is there any way to read this into an Android Image View? I was unable to do it the base64 JSON way because the string kept terminating every time I tried to put it in a JSONArray.</p> <p>Any help would be appreciated, I have been working on this since Saturday. </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
