Re: [mono-android] Nothing being passed back from a webservice
Hi,
That's getting me a good bit further, but there is still something not quite
right. The new code looks like this
private string rTrack;
public ListgetUpcomingRaces(string track)
{
Listf = new List();
rTrack = track;
f = getUpcomingRacesCallBack(cb);
return f;
}
private List
getUpcomingRacesCallBack(Action> callback)
{
List f = new List();
if (checkForNetwork(true) != true)
{
f.Add("No network available");
callback(f);
}
else
{
List tableData = new
List();
POHWS.webservice.Service1 Service3 = new
POHWS.webservice.Service1();
try
{
Service3.BeginGetUpcomingRacesList(rTrack,
delegate(IAsyncResult iar)
{
tableData =
Service3.EndGetUpcomingRacesList(iar).ToList();
Android.App.Application.SynchronizationContext.Post(delegate
{
if (tableData.Count == 0)
{
tableData[0].PostTime = "No Upcoming Races
Found within the next 7 days";
}
else
{
for (int i = 0; i < tableData.Count; ++i)
f.Add(tableData[i].PostTime);
}
callback(f);
//return f;
}, null);
callback(f);
}, null);
}
catch (Exception oe)
{
f.Add(oe.ToString());
callback(f);
//return f;
}
}
return f;
}
I have tried this code and it returns nothing (much as before). Now, if I
change the 2nd method to a void, how can I then propogate List to
return it to the caller?
Thanks
Paul

[mono-android] UI threading problem
Hi,
This could possibly be down to my current state of needing sleep but then
again, it could be something else. I've searched for examples on how to fix
the problem below, but can't seem to find what I need and it's starting to
drive me potty!
Essentially, I have a race condition whereby the webservice is finishing way
after return has been given to the UI, so the UI is not displaying anything
at all.
Here's the code. The webservice does actually get the correct data which is
the pain of it all! The generateNewScreen method comes as a result of
clicking some text on a ListView area
(calling routine)
private void generateNewScreen(int t)
{
string[] races = new string[] { };
View currentview =
FindViewById(Resource.Id.relLayout);
TextView text =
FindViewById(Resource.Id.textTitle);
ListView listView =
FindViewById(Resource.Id.listView);
ImageView image =
FindViewById(Resource.Id.imgBack);
image.Visibility = ViewStates.Visible;
Console.WriteLine("t = {0}, addFactor = {1}", t,
addFactor);
switch (addFactor)
{
case 0:
switch (t)
{
case 0: races =
listviewInfo(Resource.Array.RaceTracks,
Resource.Drawable.Back_RaceHorsePlace, Resource.String.Tracks);
addFactor = 10;
break;
case 1: List
race = new List();
currentview.SetBackgroundDrawable(Resources.GetDrawable(Resource.Drawable.Back_BobMoore));
text.Text =
Resources.GetString(Resource.String.ComingSoon);
webservice_user
getRace = new webservice_user();
race =
getRace.getUpcomingRaces("RP");
races =
race.ToArray();
addFactor = 20;
break;
}
if (t < 6 || t == 7)
listView.Adapter = new
ArrayAdapter(this, Resource.Layout.listview_layout, races);
break;
}
(webservice)
private string rTrack;
public List getUpcomingRaces(string track)
{
List f = new List();
rTrack = track;
getUpcomingRacesCallBack((list) =>
{
f = list;
});
return f;
}
private void getUpcomingRacesCallBack(Action>
callback)
{
List f = new List();
if (checkForNetwork(true) != true)
{
f.Add("No network available");
callback(f);
}
else
{
List tableData = new
List();
POHWS.webservice.Service1 Service3 = new
POHWS.webservice.Service1();
try
{
Service3.BeginGetUpcomingRacesList(rTrack,
delegate(IAsyncResult iar)
{
tableData =
Service3.EndGetUpcomingRacesList(iar).ToList();
Android.App.Application.SynchronizationContext.Post(delegate
{
if (tableData.Count == 0)
{
f.Add("No Upcoming Races Found within
the next 7 days");
callback(f);
}
else
{
for (int i = 0; i < tableData.Count;
++i)
f.Add(tableData[i].PostTime);
callback(f);
}
}, null);
}, null);
}
catch (Exception oe)
{
f.Add(oe.ToString());
callback(f);
}
}
}

[mono-android] Returning back from an activity that calls a SetWebViewClient
Hi,
Hi,
I have a simple problem
Activity A calls Activity B
Activity B has a webview and looks like this
SetContentView(Resource.Layout.webView);
WebView webView = FindViewById(Resource.Id.webView1);
webView.Settings.JavaScriptEnabled = true;
webView.LoadUrl(url);
webView.SetWebViewClient(new dealWithWebView());
In dealWithWebView(), I have this
class dealWithWebView : WebViewClient
{
WebView webView;
public override void OnPageFinished(WebView view, string url)
{
webView = view;
Context c = webView.Context;
// it goes away and does something
// calls another method in the class which returns back here
}
}
Problem is that I don't seem to be able to get it to return back from the
WebViewClient and then from "B" return back to "A".
How do I do this?

Are there any code examples of these specific to Mono for Android?
This is seriously annoying me now. I've used XML before now in another app
which is easy enough to do, but does seem overkill. Looking on the docs for
the ContentProvider, it seems to be best suited to apps sharing data rather
than sharing within the app itself.
Thanks for everything so far :)

Re: [mono-android] Being driven insane....
Hi, Re XML serialization... Typically, I would use (say) foo p = new p(); System.Xml.Serialization.XmlSerializer x = new System.Xml.Serialization.XmlSerializer(p.GetType()); x.Serialize(Console.Out, p); Obviously, I can't use Console.Out, so where do I need to point it to (for example a temporary file or something like that)?

Re: [mono-android] Being driven insane....
Hi,
Hmm, something is still not right. Are there any types which cannot be
serialized for Android?
Currently, I have this
[Serializable()]
public class common
{
public int p, a, w, pa;
public double bodyWeight, tempBody, tempSurround;
public double[,] correctionData = new double[3, 20];
public double[,] iterations = new double[3, 20];
public double c, b, cas;
public string s;
}
and to serialize in the main tab creator
[Activity(MainLauncher = true, Label = "@string/ApplicationName", Theme
= "@android:style/Theme.NoTitleBar")]
public class AndroidTimeOfDeath : TabActivity
{
protected override void OnCreate(Bundle bundle)
{
common data = new common();
base.OnCreate(bundle);
SetContentView(Resource.Layout.Main);
TabHost.TabSpec spec;
Intent intent;
intent = new Intent(this, typeof(TimeTemp));
intent.AddFlags(ActivityFlags.NewTask);
XmlSerializer x = new XmlSerializer(data.GetType());
StringWriter o = new
StringWriter(System.Globalization.CultureInfo.InvariantCulture);
x.Serialize(o, data);
// etc
}
The Serialize crashes and burns with a System.ArgumentException
I'm trying to figure out why this is happening and wonder if there are any
types that cannot be serialized. From a search, in standard C# Arrays of
ArrayList and certain generics can't be handled. Does Android add anything
additional to these?
I have changed the [Serializable] to [Serializable()] as well as commenting
it out and that makes no difference. The data.GetType() I have also tried as
typeof(common). Still crashes and burns.
Thanks
Paul

[mono-android] Non-serializable types in Monodroid?
Hi,
Simple question - other than types not serializable in standard C#, are
there any other additional types which cannot be serialized in Monodroid?
I'm trying to serialize a class (below) using the code below that, but it
dies when I try to serialize the class.
[Serializable]
public class common
{
public int p, a, w, pa;
public double bodyWeight, tempBody, tempSurround;
public double[,] correctionData = new double[3, 20];
public double[,] iterations = new double[3, 20];
public double c, b, cas;
public string s;
}
and to serialize
[Activity(MainLauncher = true, Label = "@string/ApplicationName", Theme
= "@android:style/Theme.NoTitleBar")]
public class AndroidTimeOfDeath : TabActivity
{
protected override void OnCreate(Bundle bundle)
{
common data = new common();
base.OnCreate(bundle);
SetContentView(Resource.Layout.Main);
TabHost.TabSpec spec;
Intent intent;
intent = new Intent(this, typeof(TimeTemp));
intent.AddFlags(ActivityFlags.NewTask);
XmlSerializer x = new XmlSerializer(data.GetType());
StringWriter o = new
StringWriter(System.Globalization.CultureInfo.InvariantCulture);
x.Serialize(o, data);
// etc
}
The Serialize crashes and burns with a System.ArgumentException
The serializer code looks right, so I'm trying to see if there is something
in the class being serialized that Monodroid objects to.
Any help would be appreciated.

[mono-android] Deserialize from Intent.GetStringExtra issue
Hi,
I'm slowly getting there (which is always good).
Serializing my class and passing it to other classes seems to be working.
Unfortunately at the other end, things aren't as good - I'm getting a null
exception.
common data;
public void deserialize()
{
System.Xml.Serialization.XmlSerializer t = new
System.Xml.Serialization.XmlSerializer(typeof(common));
StringReader reader = new
StringReader(Intent.GetStringExtra("mydata"));
data = (common)t.Deserialize(reader);
}
This should be enough to deserialize and assign to data.
The serialize code looks like this
common data = new common();
//
XmlSerializer x = new XmlSerializer(typeof(common));
StringWriter o = new
StringWriter(System.Globalization.CultureInfo.InvariantCulture);
x.Serialize(o, data);
intent.PutExtra("mydata", o.ToString());
I'm assuming that I've used PutExtra correctly and that "mydata" is the
token I need to pull in the deserialize step.
Help I'd like to see the back of this app now ;)
