How to create a profile in Xamarin Forms, take 2

Hello!

Way back in April I tried to figure out how to automatically configure the profile to set up basic text formatting output. That thread is here:

Since the configuration was relatively simple, I left that task until last, and I am just now getting to implementing the code. After three days of searching and trying, I am not able to get auto import to work in any way, shape, or form. I have tried both a profile, and a configuration. I used the same names that were created by the export. I've tried at least three methods of copying the file. Nothing has worked. Help?

Here's my c# code:

using System;
using System.IO;
using Java.IO;
using System.Threading.Tasks;
using Xamarin.Forms;
using Android.Views;
using Android.Content.Res;
using Plugin.CurrentActivity;
using Acr.UserDialogs;

...

        private bool setuptask()
        {

            // Somewhere I saw a recommendation to not name the asset with a "known" suffix, use

            // something like .dat instead. So I tried that...
            string importpath = "/enterprise/device/settings/datawedge/autoimport/";
            string tempfile = "/enterprise/device/settings/datawedge/datawedge.dat";
            string importfile = "/enterprise/device/settings/datawedge/autoimport/datawedge.db";
            string otherfile = "/enterprise/device/settings/datawedge/autoimport/dwprofile_ScanOrders.db";
            string assetname = "datawedge.dat";
            string filename = "datawedge.db";

            try
            {
                // Make sure directory exists...
                if (Directory.Exists(importpath) == false)
                {
                    Directory.CreateDirectory(importpath);
                }

                // Clear out any old files... I have been switching back and forth

                // between the two files, so I clean up both of them before re-copying.
                if (System.IO.File.Exists(tempfile) == true)
                {
                    System.IO.File.Delete(tempfile);
                }

                if (System.IO.File.Exists(otherfile) == true)
                {
                    System.IO.File.Delete(otherfile);
                }

                // If I set a breakpoint here. The second time I call the function,

                // the file exists. (I wait a minute or two before the 2nd call.)
                if (System.IO.File.Exists(importfile) == true)
                {
                    System.IO.File.Delete(importfile);
                }

                // Create temp file from our assets
                Android.App.Activity context = CrossCurrentActivity.Current.Activity;
                AssetManager assets = context.Assets;

                using (BinaryReader br = new BinaryReader(assets.Open(assetname)))
                {
                    using (BinaryWriter bw = new BinaryWriter(new FileStream(tempfile, FileMode.Create)))
                    {
                        byte[] buffer = new byte[2048];
                        int len = 0;
                        while ((len = br.Read(buffer, 0, buffer.Length)) > 0)
                        {
                            bw.Write(buffer, 0, len);
                        }
                    }
                }

              

                // Move the file into place so auto import doesn't try to pick it up before

                // the copy is complete.
                System.IO.File.Move(tempfile, importfile);

         

                // Set permissions, in case that was the problem. I was setting executable, but

                // saw example code that the author claimed worked, and he only set readable and

                // writable. So I took it back out.
                using (var newfile = new Java.IO.File(importpath, filename))
                {

                    // I added this bit so I could check that the file is actually

                    // created. I don't know if the contents are correct, but the copied

                    // file is ~9000 bytes long.
                    long len = newfile.Length();
                    if ((newfile.Exists() == false) || (len < 1.0))
                    {
                        // Error                   
                    }
                    else
                    {
                        newfile.SetReadable(true);
                        newfile.SetWritable(true);
                    }
                }
            }
            catch (Exception e)
            {
                UserDialogs.Instance.Alert("Exception caught: " + e.Message, "Error");
            }

            return true;
        }
