Hi,

also I am getting an error after displaying another Master-Detail page and than switching back to the Map page (like the MapPins-Clear() exception.

After switching back to the Map page and clicking on a Pin I am getting this error (again clicking on the Pin the first time, before using the Master/Detail page) there is NO problem clicking the Pin):

Add commands for:

UserLocationChanged

After upgrading the version of the package (to last), the methods add and clear the CustomPins Collection were removed, what happened?

TKCustomMap map;
var CustomPin = new TKCustomMapPin ();
CustomPin.ShowCallout = true;
CustomPin.DefaultPinColor = Color.Red;
CustomPin.Position = new Xamarin.Forms.Maps.Position (item.Y,item.X);
CustomPin.Title = item.Value.ToString ();
CustomPin.Subtitle = item.Endereco;
map.CustomPins.Add(CustomPin);

Dragging a pin via user is very useful, but what if I want to animate the pin via code?
For example, live tracking a car, the car presenting the pin would be moving by updating its location, is this possible?

When installing the nuget, it requires some dependencies, on which Microsoft.Net.Http, which depends on Microsoft.Bcl.Build. This is not available for iOS projects.
Is there a way to solve that? (I have just added the nuget manually to the iOS project, don't know yet if it works...)

I just came across this, but it looks like when using TKCustomMapPin on Android, your pin is anchored at the bottom of the image, but on iOS it's anchored in the center of the image.

Is this expected?

It would be great if it were the same for both platforms and potentially customizable

Hi all,

I really like your work but i have a problem

I included your package to my xamarin forms project and i've created a page where:

1. I get the device position
2. I center the tkcustommap to my position
3. I place the mapspan to mapspan(myPosition,distance.fromkilometers(1))
4. I place a pin to myPosition
5. I place a circle centered in myPosition with radius driven by a slider

all of this work on Android and iPhone but on iPad the mapspan is always equal to default and nothing appear(pin and circle)

One thing to notice:
sometimes my app work on iPad if i build it in debug or ad-hoc mode
if I build in AppStore mode it doesn't work on iPad

Ty for your work

After updated the TKCustomMap, I needed to update other components of my project, including Xamarin.Forms. Thus, the compilation started giving the following errors:

Error CS0117 'Resource.Styleable' does not contain a definition for 'Theme_windowNoTitle' ProjectName.Droid C:....\Droid\Resources\Resource.designer.cs 1574
Error CS0117 'Resource.Styleable' does not contain a definition for 'Theme_windowMinWidthMinor' ProjectName.Droid C:....\Droid\Resources\Resource.designer.cs 1573

Error CS0117 'Resource.Styleable' does not contain a definition for 'Theme_windowFixedWidthMinor' ProjectName.Droid C:....\Droid\Resources\Resource

It has over 148 resource errors.

using SampleProject - Tested on iOS9.2 simulator and 8.3 device.

As far as I can see, the method
GetViewForAnnotation
get's called, and depending on if FormsMap.CalloutClickedCommand != null, it adds the button.

On previous XamarinForms, it was working as expected; but with last version, CalloutClickedCommand remains null; also PinSelectedCommand is null

SOLVED:

Took a while to debug this issue; the problem was (in SampleProject and my project):

instead of
public Command CalloutClickedCommand

it needs to be
public Command<TKCustomMapPin> CalloutClickedCommand

same with PinSelectedCommand; if Command<T> is not specified, it ends up as NULL in renderer. I guess this is action binding changed by Forms.

Hi Torben,

I got an unhandled exception when I tried to add a pin with a custom image on Android device.
After searching a bit, it seems that a java.lang.NullPointerException is thrown in TKCustomMapRenderer.cs at line 459 :
this._markers.Add(pin, this._googleMap.AddMarker(markerWithIcon));

Here's the exception :

01-22 15:13:10.818 I/mono-stdout( 6446): Exception : Java.Lang.NullPointerException: Exception of type 'Java.Lang.NullPointerException' was thrown.

01-22 15:13:10.818 I/mono-stdout( 6446):   --- End of managed exception stack trace ---

This is my code (I used your sample for the test) :

var pin = new TKCustomMapPin
{
    Position = position,
    Title = string.Format("Pin {0}, {1}", position.Latitude, position.Longitude),
    ShowCallout = true,
    IsDraggable = true,
    Image = ImageSource.FromFile("pinImage.png")
};
this._pins.Add(pin);

When I try to run tit on iOS simulator, there's no Exception but the pin won't be displayed on the map.

Thanks for your work,
po-connor

Changing pin Positionat android target works fine, however changing the pin Positionwill not effect the pin location at map in iOS, it seems that the pin Positionbinding is not working for iOS ?! 😢

Hi,

I'm getting this error when I show a page with a map, then pop that page and push another page with a map; it sems a silent error(no crash)

It's intermittent so perhaps a race condition.

Again, I can't reproduce it every time, it just happens randomly which is why I suspect a threading issue.

Hello,
I sorry for my bad English.

I need to make the TK Custom Map in a Bindable Object to create the Location property, Title, etc. Bindable. To do this I need the TKCustomMapPin inherit from bindableobject class.
You could make this change?
Thank you Regards
Manni Tiziano

I was unable to add a route on the map because the latitude and longitude were added to the URI with a comma instead of point (eg.: origin=40,7830603,-73,9712488&destination=40,7127837,-74,0059413). The problem occurs in TK.CustomMap.Extensios.AsString(Position).

How do I change the zoom level by the code?

I'm testing the latest version and tried to add a button through the event "MapLongPress" recently available, however on the callout not appear the button with the "i".

map.MapLongPress += async (sender, args) =>
            {
                var newPin = args.Value;     
var pin = new TKCustomMapPin
                                {
                                    Position = new Xamarin.Forms.Maps.Position(newPin.Latitude, newPin.Longitude),
                                    DefaultPinColor = Color.Blue,
                                    Title = "(New Point)",
                                    Subtitle = "Test SubTitle",
                                    ShowCallout = true,
                                    IsDraggable = true,

                                };
                                ObservableCollection<TKCustomMapPin> obPin =new ObservableCollection<TKCustomMapPin>();
                                obPin.Add(pin);

                                IEnumerable<TKCustomMapPin>  pinList = map.CustomPins;
                                map.CustomPins= map.CustomPins.Concat(obPin);
}

Previously used by a ViewModel for this event following his Sample.

Hi,

thanx for the fix concerning SetMapCenter()....no problems here any more.

BUT: I have a new problem in OnCollectionChanged(). I am clearing my MapPins collection and adding a new pin with updated GPS data.

While calling this.MapPins.Clear () a second time I am getting this error:

Hi Torben,

Just upgraded to 1.1.0 - FANTASTIC work :) 👍 One bug I've found so far is this crash when I try to clean a collection:

I have tried to embbed the map into a TabbedPage.
It works fine on Android, however it fails on iPhone (the map is white/not displaying). An idea why?

(Setting the BindingContext before displaying also causes a lot of troubles!)

It would be really great to have a way to zoom and move (animated would be a bonus) the map to either a specified region or to simply focus on the calculated route so that it fills the view rectangle.

i.e. iOS native you can do something like:

        var zoomRect = MKMapRectNull

        for overlay in overlays {
            zoomRect = MKMapRectUnion(overlay.boundingMapRect, zoomRect)
        }

        let updatedMapRect = self.mapView.mapRectThatFits(zoomRect)

        self.mapView.setVisibleMapRect(updatedMapRect, edgePadding: UIEdgeInsetsMake(mapPadding, mapPadding, mapPadding, mapPadding), animated: true)

Allowing either the helper function to zoom/focus on the route or providing helper functions to help with the calculations would be great. Right now I can only choose a center position and zoom level.

Is it possible to remove the 'legal' text from the iOS map? It looks like a tappable link but you can't tap on it.

Instead we will be showing all legal information in the About screen and don't need it on the map.

So if you're offline or in flight mode you get this crash and it'll take down your app.

To reproduce, go offline, then start an app that uses TK.CustomMap on Android

Can we change the dependency on google location services from "exactly 26" to "at least 26"?
If I install v26 in my project I get an "already added" exception from java when building, because two different google play services are installed (26 and 29).

Strange thing on iOS only. My MapClick command is not triggering when I build the iOS app in Release mode. Debug mode works fine.

I tried turning off the Linker in Release mode just to see if it was a linking issue and that made no difference. I have my Debug and Release builds identical in settings and only the Release mode build does not trigger the MapClick.

Any ideas?

This only happens on iOS as on Android you're doing the FormsMap.PropertyChanged event registration call in OnElementChanged.

On iOS however it seems the MapLoaded can be called multiple times. For me it can get called 2-3 times without any calls to OnElementChanged. Once when the map is first initialized and again when it's finished animating to it's destination MapCenter

            this.FormsMap.PropertyChanged += OnMapPropertyChanged;

As a test I unregistered right before

            this.FormsMap.PropertyChanged -= OnMapPropertyChanged;
            this.FormsMap.PropertyChanged += OnMapPropertyChanged;

and I no longer get multiple PropertyChanged notifications

Hi - been working away nicely on iOS, and the package has been awesome! Moved over to upgrade my Droid app, and get the following on Xamarin Studio running on OSX:

/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.targets: Error: Exception while loading assemblies: System.IO.FileNotFoundException: Could not load assembly 'Xamarin.GooglePlayServices.Location, Version=1.0.0.0, Culture=neutral, PublicKeyToken='.

Hi there - great v1 of a nice custom map/pin implementation, I've branched a project I'm working on and implemented your lib. Here is some feedback:

• One of the key things that seems to be missing vs the 'native' Xamarin Forms map is the ability to click on the call out to fire an event. In my app for example, the user has a bunch of pins based on their location, the click on the pin to get some more info, then click on the call out to open the full details screen.
• If I clear an ObservableCollection before re-adding a bunch of pins, the new pins are added, but the old ones are not cleared.
• The pins sit on top of the users current location, often hiding their location.

I really like what you've got as a start, and happy to help test on a real world app if you would like :) Keep up the good work 👍

Cheers,
Kolchy

I realise this is probably something I'm doing wrong but I've been banging my head against this wall for many hours and I'm not sure how else I can open a discussion with you @TorbenK

I've Enabled the Places API, I've enabled Android Maps support, I've generated an Android Key and locked it to my package, verified the SHA-1 is correct and verified that the apk I'm using was signed correctly.

For the init calls in your sample you use:

GmsPlace.Init("YOUR API KEY");
            GmsDirection.Init("YOUR API KEY");

Am I supposed to have 2 seperate API keys there or are they the same key? Right now I just seem to have the 1 key which I use for both (Credentials ->CreateCredentials->ApiKey->Android Key). I've also tried leaving off the GmsPlace call since I only really need the Direction Api.

I've also updated my Android.manifest with:

<meta-data android:name="com.google.android.geo.API_KEY" android:value="YOUR API KEY" />

Again, is this the same API KEY I'm using in the above 2 calls?

If doesn't matter if I switch this to com.google.android.maps.v2.API_KEY instead of com.google.android.geo.API_KEY, I still get RequestDenied.

If I look in the Developer console at my Google Maps API usage, I can see that the calls are coming through and they all have 'Success' next to them. The Google Maps Directions API usage though has Client Errors (4xx) next to all of them though.

I was following the checklist from here: http://stackoverflow.com/a/25374435/10957 (Even though it's for the web service)

Any other ideas? Is there a better error log I can look at to see what the real problem is?

I just had this occur on a device that a tester was using. Not sure yet on reproduction steps but thought I'd report anyway:

Message:

Error using newLatLngBounds(LatLngBounds, int): Map size can't be 0. Most likely, layout has not yet occured for the map view. Either wait until layout has occurred or use newLatLngBounds(LatLngBounds, int, int, int) which allows you to specify the map's dimensions.

Sorry @TorbenK I think it's a stupid question...but I don't find a solution.
I have created a Google API KEY for Debug and for Release. I have inserted my Key on AndroidManifest (tried with DEBUG and RELEASE), but the app is not show.
Which could be the problem?
Do I write the key also in

        GmsPlace.Init("YOUR API KEY");
        GmsDirection.Init("YOUR API KEY");

Perfrect solution would be to have a Xamarin.Forms View as template for the callout.

Secondary solution would be to override a function in the renderer to return a native view for the callout.

Hi,

I'm trying to add some lines on a TKCustomMap.
Below code works great on Android (so I think it's right) but cause a "System.Collections.Generic.KeyNotFoundException" on iPhone.
("Polylines" is a bindable property : ObservableCollection Polylines)

var coords = new List<Position>();
coords.Add (new Position (48.8583, 2.2944));
coords.Add (new Position(48.8683, 2.2924));
coords.Add (new Position(48.9683, 2.2924));

TKPolyline polyline = new TKPolyline(){
    Color = Color.Green,
    LineWidth = 10,
    LineCoordinates = coords,
};
Polylines.Add (polyline);

These are exception details :

Attached is a test project that reproduces it. Simply wait for it to load once, then 'double tap' the reload button.

TestTkCustomMap.zip

A user should be able to double tap the map to zoom in without triggering the MapClickedCommand. Therefore, the tap listener needs to wait to make sure it isn't a double tap event before firing the MapClickedCommand.

I merged your development changes into my fork because I needed the fix for the unrecognised selector and saw that you also had done the anchor points work! Thanks!

However I noticed that on iOS I see the markers flicker on the view for a moment as the map calculates the route, then when the route is rendered, the markers disappear. If I don't use a custom image for the markers, the standard pins animate in and show just fine.

On Android it seems to be working just fine.

I use the following in the RouteCalculationFinishedCommand:

if (Route.All(i => i.IsCalculated))
{
    MapView.FitToMapRegions(Route.Select(i => i.Bounds), false);
}

Just to add to this, if the map is scrolled to a location not within the pins/route, I'll see a couple of flickers of the custom pin graphics and the route and then the pins disappear.

If I refresh the pins/route collection (and the rectangle is still the same), the pins appear and stay on the screen this time.

If the view rectangle is already over the pins/route when the collection changes, the pins update correctly (including adding new pins)

The items returned from INativePlacesApi are too simple. As best as possible, each property of the underlying native API should be kept separate in IPlaceResult and not all combined together in the Description. Also, the important Name property is not being put inside the Description return value. So if I search for "Donuts" in the sample app, I expect to get back things like "Dunkin Donuts", but I just get back the addresses since the Name is not put inside the Description property.

So I'm not 100% sure if this is a bug or if it's something you might need to document as a gotcha, but thought I'd make you aware as it seems to have caused some issues in my project:

I would calculate the route and receive my RouteCalculationFinishedCommand events, and I'd wait for the route calculation to be done:

if (Route.All(i => i.IsCalculated))
{
    MapView.FitToMapRegions(Route.Select(i => i.Bounds), true);
    CalculatingRoute = false;
}

CalculatingRoute is a property I was using to show a progress spinner to show the calculation was busy.

Then when the FitToMapRegions has run, the iOS map animates over to the region and when it's there another MapLoaded event comes through.

This in turn runs:

this.UpdateRoutes();

Which then again goes out and sends out all the RouteCalculationFinishedCommand.

In my code then for every RouteCalculationFinishedCommand, as the Route was already previously calculated, I was then calling FitToMapRegions every single time I got that RouteCalculationFinishedCommand. This then resulted in more calls to MapLoaded depending on race conditions.

I've now fixed this in my code by checking first to ensure I'm expecting that the route hasn't been calculated by using my CalculatingRoute property.

if (CalculatingRoute && Route.All(i => i.IsCalculated))
{
    MapView.FitToMapRegions(Route.Select(i => i.Bounds), true);
    CalculatingRoute = false;
}

@TorbenK I'll leave it up to you for the fix as I'm not sure which way you want to go about it :)

Hi, i want to contribute improving how you handle the UpdateImage call (at least on Android platform, don't know if IOS already handle ImageSource by stream flawless

anyway, you have on TKCustomMapRenderer.cs in Android platform, two methods

private async Task UpdateImage(TKCustomMapPin pin, MarkerOptions markerOptions)
private async Task UpdateImage(TKCustomMapPin pin, Marker marker)

there you check to see if the user wants a custom image and load it, this way

if (pin.Image != null)
                {
                    Android.Graphics.Bitmap icon = null;

                    if (pin.Image is FileImageSource)
                    {
                        icon = await new FileImageSourceHandler().LoadImageAsync(pin.Image, this.Context);
                    }
                    else
                    {
                        icon = await new ImageLoaderSourceHandler().LoadImageAsync(pin.Image, this.Context);
                    }
                    bitmap = BitmapDescriptorFactory.FromBitmap(icon);
                }

the problem is that i need to use a StreamImageSource because i generate runtime a bitmap (with rotation and tilt) and if i just set the Image property of the TKCustomMapPin (you allow it), then i fall into your "else" that try to use an ImageLoaderSourceHandler, that rise an exception

so my solution is easy and works, just add to your TKCustomMapRenderer class this method

private static IImageSourceHandler GetHandler(ImageSource source) {
         IImageSourceHandler returnValue = null;
         if (source is UriImageSource) {
            returnValue = new ImageLoaderSourceHandler();
         }
         else if (source is FileImageSource) {
            returnValue = new FileImageSourceHandler();
         }
         else if (source is StreamImageSource) {
            returnValue = new StreamImagesourceHandler();
         }
         return returnValue;
      }

and then replace

if (pin.Image != null)
                {
                    Android.Graphics.Bitmap icon = null;

                    if (pin.Image is FileImageSource)
                    {
                        icon = await new FileImageSourceHandler().LoadImageAsync(pin.Image, this.Context);
                    }
                    else
                    {
                        icon = await new ImageLoaderSourceHandler().LoadImageAsync(pin.Image, this.Context);
                    }
                    bitmap = BitmapDescriptorFactory.FromBitmap(icon);
                }

on both UpdateImage methods, to this

if (pin.Image != null) {
               var handler = GetHandler(pin.Image);
               Android.Graphics.Bitmap icon = await handler.LoadImageAsync(pin.Image, this.Context).ConfigureAwait(false);

               bitmap = BitmapDescriptorFactory.FromBitmap(icon);
            }

that's more elegant (don't duplicate code) and works even for StreamImageSource

bye

In OnRoutePropertyChanged you do

var item = this._routes.SingleOrDefault(i => i.Value.Overlay.Equals(route));

Sometimes because of a race condition, this _routes list will have multiple of the same route and therefore this will assert.

As far as I can tell, this happens from the AddRoute function where it's added in the completion handler of the CalculateDirections call.

I'm still trying to reproduce it 100% so I can create a test project or fix it myself and send a pull request.

I think it might be if you change the route data while it's still calculating a previous route, but that's a guess.

Hi,

I am working with Tk.CustomMap on Xamarin Forms XAML. and I am getting this error:

System.MissingMethodException: Default constructor not found for type TK.CustomMap.TKCustomMap

When I open the page which contains the map, that error shows up and my app closes.

I have uninstall the nugget, and reinstalled, I have done all the settings correctly, still I cant get it to work .

Please help!

My XAML looks like this:

<ContentPage.Content>

    </Image.GestureRecognizers>
  </Image>
</Grid>

</ContentPage.Content>

and my code:

            Geocoder geo = new Geocoder();
            List<TKCustomMapPin> pins = new List<TKCustomMapPin>();
            foreach (LocationObject location in Globals.Places)
            {
                var position = new Position(double.Parse(location.Latitude.ToString()), double.Parse(location.Longitude.ToString()));
                var pin = new TKCustomMapPin();
                pin.Position = position;
                pin.Title = location.Name;
                pin.Image = Device.OnPlatform("wine.png", "wine.png", "Assets/wine.png");

                pins.Add(pin);
            }

            MyMap.CustomPins = pins;

Hey Torben,

Another small issue I found. On iOS, you need to click the pin twice to get the callout to show. I added a PinSelectedCommand that just shows Debug.WriteLine("Pin clicked"), and if I tap the pin once, I see the message, then tap again and the call out shows?

Cheers,
Kolchy

I'm having this problem and I am using your CustomMap and CustomPin.
Can you have something to do?

https://forums.xamarin.com/discussion/63003/pins-do-not-appear-in-release-mode?new=1

I've tried using the default image pins and a picture and none of the two cases worked.

I have an iPhone 6.
If I connect the iPhone to my MAC and debug your demo app, it works (I can search an address, do long tapping...) but if I create an IPA and install the IPA, it does not work (no search, no long tap), only the map is visualized...
Where is the problem?
Thanks
