Cross-platform Native API Access from Shared Code!

Plugins for .NET, Xamarin, and Windows

Here is my essential list of official and community plugins and libraries for applications. You will find a lot of Xamarin and Xamarin.Forms libraries, but also great libraries for .NET that can help power your apps. If you have a favorite library or are the creator of one, please send a PR!

Xamarin.Essentials: The stuff your app needs

Xamarin.Essentials gives developers essential cross-platform APIs for their mobile applications. Xamarin.Essentials exposes over 60 native APIs in a single cross-platform package for developers to consume in their iOS, Android, UWP, or Xamarin.Forms application. Browse through the documentation on how to get started today.

The repository for Xamarin.Essentials can be found at https://github.com/xamarin/Essentials. If you have any suggestions or feature requests, or if you find any issues, please open a new issue.

If you have bene using my plugins, I will continue to support the ones that aren't in Xamarin.Essentials, but I recommend you transition using my guide.

Shiny: That complex stuff made easy

Shiny is an amazing project from Allan Ritchie, Microsoft MPV and long time Xamarin developer, that makes really complex native functionality easy. This includes things such at Bluetooth LE, Background Jobs, HTTP Transers, Push Notifications, NFC, and more.

Community Provided Open Source Plugins

Plugins for Xamarin are community built NuGet and Components that add cross-platform functionality or abstracts platform specific functionality to a common API. These are both completely cross-platform and extremely small (i.e., they do 1 or 2 things really well with minimal-to-no dependencies). The Plugin API can be accessed on each platform, however, you will most likely only use the common API in a .NET Standard project.

Notice: Plugins for Xamarin featured here are produced by the amazing open source community of Xamarin developers. Xamarin does not provide official support for these plugins, please contact their creator with any issues.

Create a Plugin for Xamarin

If you are looking to create a plugin be sure to browse through NuGet first and ensure that the plugin doesn't exist. If one does join in on the fun and collaborate. If it doesn't and you want to start building a Plugin here are some tools and guidelines to get you started.

Tools to get Started

• Visual Studio Plugin Templates: Provides a complete plugin template and easy NuGet specification to publish.
• Using & Developing Plugins for Xamarin: Join Developer Evangelist James Montemagno as he walks you through creating a plugin from scratch on Xamarin University

Requirements of a Plugin

• Open source on GitHub
• Documentation on GitHub's README file
• Name: "FEATURE_NAME Plugin for Xamarin and Windows"
• Namespace: Plugin.FEATURE_NAME
• App-store friendly OSS license (we like MIT)
• No dependency on Xamarin.Forms
• Have a list of supported and unsupported OSs in its GitHub wiki

License

Licensed under MIT see License file. Each plugin licensed under parent license unless stated in it's readme file.

xamarin.plugins's Issues

Xam.Settings - not working in iOS unified environment

I converted an existing Xamarin forms with Settings plugin1.5 to unified iOS.
I got an error message that monotouch.dll is used by Settings ( which clashes with Xamarin.ios)

How to handle settings property changed

I have some settings bound to a view in my app, but when I update the settings the view does not update. Does anyone know how to properly handle this? I didn't find it in the docs or the forums, so I posted it here.

Geolocator fails with infinite timeout on WinRT Phone 8.1

The Geolocator now works on Windows Phone when you supply a positive timeout. However if you leave that argument as default (-1), it will throw an ArgumentException.

A side note, the XML docs or argument name should probably mention what the units are for the timeout. Presumably milliseconds?

UnifiedAPI DeviceInfo isn't on nuget

Seems to have been a xamarin studio error or something. Sorry.

Please add support for iOS Unified API (Settings Plugin for Xamarin And Windows)

Hi,

Your plugin "Settings Plugin for Xamarin And Windows" is not compatible with Xamarin iOS Unified API.

Can you update your project ?

Thank you

[Feature Request] TakeVideoAsync & TakePictureAsync saves file within App folder. No option to provide absolute path and save in external storage.

I would like to save file here:

var _dir = new Java.IO.File(Android.OS.Environment.GetExternalStoragePublicDirectory(Android.OS.Environment.DirectoryMovies), "MyAppName");

Also, these files are not visible in the gallery apps. Would prefer if there is an optional bool parameter to do so. Currently, I use following code to achieve this:

Intent mediaScanIntent = new Intent (Intent.ActionMediaScannerScanFile);
Android.Net.Uri contentUri = Android.Net.Uri.FromFile (_file);
mediaScanIntent.SetData (contentUri);
SendBroadcast (mediaScanIntent);

ImageCircle: Xamarin.Forms 1.2.3.0 required

James,

It would appear that there is a hard dependency on Xamarin.Forms 1.2.3.0.

I created a 1.3.0 project and after installing ImageCircle and adding the ImageCircleRenderer.Init(); to the AppDelegate on iOS, I get this:

The type 'Xamarin.Forms.Platform.iOS.ImageRenderer' is defined in an assembly that is not referenced. You must add a reference to assembly 'Xamarin.Forms.Platform.iOS, Version=1.2.3.0, Culture=neutral, PublicKeyToken=null'

Thanks, Mitch

Settings: Unable to use in Xamarin Unified iOS Project?

I am trying to use the CrossSettings Library in a PCL with this line:

public static object getSetting(string key)
{
return CrossSettings.Current.GetValueOrDefault(key,string.Empty);
}

And all I get is a "System.IO.FileNotFoundException" - Could not load file or assembly 'monotouch, Version 0.0.0.0'...

I am running version 1.4.0.1 which should be unified api compatible ?
just tried.. this also happens with 2.0.0-alpha

Thanks for your help.

Hardcoded circle image inset for Android

There's a strange inset on Android for circle image. As I understand it is hardcoded here:
https://github.com/jamesmontemagno/Xamarin.Plugins/blob/master/ImageCircle/ImageCircle.Forms.Plugin.Android/ImageCircleRenderer.cs#L69

var radius = Math.Min(Width, Height) / 2;
var strokeWidth = 10;
radius -= strokeWidth / 2;

What is the point? Should we use BorderThickness there? Like that:

var radius = Math.Min(Width, Height) / 2;
var strokeWidth = ((ImageCircle.Forms.Plugin.Abstractions.CircleImage)Element).BorderThickness;
radius -= strokeWidth / 2;

Plans for supporting .NET 4.5 application in Xam.Plugin.Connectivity?

Hi,

I am currently writing a C# connector for an API, that I want to share in a Xamarin and a pure .NET application.

We lately thought about implementing Xam.Plugin.Connectivity in there, but since it has no pure .NET support, we didn't quite know how to implement that.

Are there any plans on adding support for that?

Licenses

Hey James,

I see some discrepancies with the license stated in some of my plugins and your statements in your derivative work. For the Connectivity and DeviceInfo plugin the Apache 2.0 license is used. You can see all the "Must" stuff you need to do in order to adhere to the license here: https://tldrlegal.com/license/apache-license-2.0-(apache-2.0)

Basically you have removed the copyright and license statements in the top of the files you are deriving from. You also need to state that the files have been modified. You also need to have a NOTICE file with attribution notes.

I did give you permission to use my code, which the Apache 2.0 license already states that you can do 😄. Although I am pretty certain that you can't sub-license Apache 2.0 licensed code with a less restrictive license like MIT. Although your own code can be licensed as MIT, you must retain Apache 2.0 on my code.

If you need help fixing these things, please do tell. It might be easier to change the two plugins in question to Apache 2.0.

Thanks,
Tomasz

How To access to contacts images in Xamarin.Plugins.Contacts

Hi James,

I was working with Xamarin.Mobile and I know that there the object Contact has the property GetThumbnail() that returns the current bitmap of the contact photo.

I checked your implementation and that method does not exist. There is any way that I can access to the contact photos with your library or I can implemented if you give more details how to can be done.

Also, when I was trying to use the GetThumbnail() from Xamarin.Mobile, I found it complicated to use because it was better if you can have the URI where the image is stored that return the entire image.

Could you give your ideas, how to implemented this in a better way using your library. By the way, good job creating all this libraries.

Regards,

Gabriel

Contacts.Plugin.Android: "the bind value at index 20 is null"

I haven't stepped through the ContactsPlugin code just yet to figure out what element "index 20" corresponds to, but it looks like we're not handling a null value coming back from the contacts DB properly.

Will update if I find any more info.

Thanks!

Doubts in settings plugin

Can you clarify it, please? I am trying to use it in a demo about Notification Hubs.

Unified API issue?

Hi James,

I just added package to my project but it won't build, I get:

MTOUCHTASK: Error MT2002: Failed to resolve assembly: 'Refractored.Xam.Settings, Version=1.5.0.0, Culture=neutral, PublicKeyToken=null' (MT2002)

A quick Google suggests that it is related to Xamarin's recent updates to its Unified API support. Things that worked in beta need a bit of tweaking in the final version.

Settings Plugin - Android - Loses decimal part when storing/reading doubles

Checking the code this is because doubles read/store as long. On Android Library : Xamarin.Plugins/Settings/Refractored.Xam.Settings.Android/Settings.cs
///////////////////////////////////// --- On Read

   case TypeCode.Double:
        value = (double)SharedPreferences.GetLong(key, (long)Convert.ToDouble(defaultValue, System.Globalization.CultureInfo.InvariantCulture));
        break;

////////////////////////////////////// ---- On Store

    case TypeCode.Double:
        SharedPreferencesEditor.PutLong(key, (long)Convert.ToDouble(value, System.Globalization.CultureInfo.InvariantCulture));
        break;

PickPhotoAsync Problem

CrossMedia.Current.PickPhotoAsync() on android not return real file path. It returns path in sdcard/0/Android/data//files/Picture/temp/ / it throws the System.IO.FileNotFoundException because real file is at sdcard/0/DCIM/Camera.

Default value and nullables doesn't work very well

Hi,

Try this in Android

int? id = AppSettings.GetValueOrDefault<int?>("key", (int?)null);

it will return 0 when key doesn't exist.
i think ContainsKey method would come handy when you simply want to check for key presence anyway (it could be present with null value).
I can create a pull request if it makes sense.

ExternalMaps/Android: double toString() and current culture setting

I just noticed an issue in the Android version...
The latitude / longitude values are converted tostring using the current culture settings and in some country the decimal separator "." will be replaced with "," causing a wrong format in the intent string, so googlemaps will not find any results...

Error while trying to set up the project for Xamarin.Forms Control Plugin

I am trying to use this VS extension from you:
https://visualstudiogallery.msdn.microsoft.com/afead421-3fbf-489a-a4e8-4a244ecdbb1e
but after selecting Plugin Control for Xamarin.Forms I am getting this error:

Settings Plugin for Xamarin doesnt save key value in the first run

i developing a app that in the first run get a userid from the server. i want to store it locally, however i cant do it on android. i save the value and then try to get it and the value doesnt exists.
if i close the app and open it again the value is stored.
In IOS works fine. Any idea?

Cancel

Is there a way to stop the Text To Speech after it has started? Or have an event that launches when the speaking is done?

Thanks

ImageCircle not working as expected on Android

Hello!

https://github.com/jamesmontemagno/Xamarin.Plugins/tree/master/ImageCircle, version 1.0.0.5

It works perfectly on iOS, but on Android the pixels outside the drawn circle isnt transparent. Images of how it looks on iOS and Android (S4, Android 4.4.2). Xamarin Forms version 1.3.1.6296:

CrossConnectivity.Current.IsConnected returns false after device is put in flight mode

I use this code:

bool result = CrossConnectivity.Current.IsConnected;

If I turn on flight mode it still returns true

If I try to access the internet in safari of Facebook before I do the check it returns false

Adding new key value works ONLY in AppDelegate.FinishedLaunching in MONOTOUCH

I followed readme instruction and used _SettingsStarted.txt as an example. But it works only AppDelegate.FinishedLaunching when I call Settings.UserName = "demo".

For example, If I call Settings.UserName = "demo1" in any other view controller and then use it in some classes. I don't see that UserName value has changed.

Can you please help me with this.

[Feature Request] Media Plugin - Continues scanning?

Would it be possible to add a continues scanning feature to your library? Optimally with a callback on every frame that await the byte stream? Also access to the camera to enable auto focusing or other various features would be great.

That way it would be possible to create a barcode decoder using zxing.mobile.

Default DesiredAccuracy

i don't think that DesiredAccuracy's defualt value 0 is a good choice. That way you won't ever get a position since retrieved accuracy is always greater than 0.
Perhaps a value of double.MaxValue is a better choice?

wrt incorrect Media Plugin picture orientation

Hi Mr James,

is there any easy way to rotate the image after selecting it from the gallery (with the Media Plugin)?

Unable to install Xam.Plugin.Connectivity using Xamarin Studio

Can we relax the min client requirement in some of the NuGet packages? There are a few NuGet packages that have the following in the .nuspec:

minClientVersion="2.8.3"

The minClientVersion is preventing the NuGet packages being installed in Xamarin Studio. Xamarin Studio currently reports 2.8.1 as its NuGet client version. Xamarin Studio has not been updated to NuGet 2.8.3.

When you try to install Xam.Plugin.Connectivity into a project in Xamarin Studio it fails with the error:

Adding Xam.Plugin.Connectivity...
The 'Xam.Plugin.Connectivity 1.0.0.0' package requires NuGet client version '2.8.3' or above, but the current NuGet version is '2.8.1.0'.

The following NuGet packages seem to specify 2.8.3 as its minClientVersion:

• Xam.Plugins.Forms.Vibrate
• Xam.Plugins.Forms.ImageCircle
• Xam.Plugins.Vibrate
• Xam.Plugin.DeviceInfo
• Xam.Plugin.Connectivity
• Xam.Plugins.TextToSpeech

Connectivity sample crashes when in aeroplane mode

James, some great plugins thanks.

I ran the Connectivity sample
from Xamarin.Plugins\Connectivity\Common\ConnectivityPlugin\samples
using Android 21 on my Nexus 5 (built in XS 5.7) and if I put my phone in aeroplane mode and then press the Test connectiion button the app disappears (crashes).

ImageCircle bug in Android

Hi,

I'm using ImageCircle in a viewCell of a ListView.

as BindingContextChanged is use this method:

void ReadingCell_BindingContextChanged(object sender, EventArgs e)
{
var c = BindingContext as DbModel.Reading;
_circleT.BorderColor = MyColor.GetTemperatureColour(c.temperature);
}

I change the borderColor using a temperature.
On the visible cells, all work as expected, but if I scroll the ListView and then I return up to the previous cells, I see that the borderColor of the previous cells is now wrong (the color is the same of the ImageCircles on the screen before I scroll up).

On iOS all work perfect, i can scroll as much as i want and all the imagecircles still have the correct color.

How to use CircleImage in XAML

I am trying to use CircleImage in Xaml, but it doesn't seem to want to work. Anyone know how to make it work?

I added this to my ContentPage tag:
xmlns:ic="clr-namespace:ImageCircle.Forms.Plugin.Abstractions;assembly=MyApp"

Xaml Code:
<ic:CircleImage Source="misc/example_image.jpg" WidthRequest="50" HeightRequest="50" Aspect="AspectFill" HorizontalOptions="Center" />

CrossConectivity return false in emulator

Hi James,

I was trying to use the Connectivity.Plugin.CrossConnectivity to checked the current connectivity of the device. However, the method Current.IsConnected is always false even if I have internet active in the emulator device. Can you give a hint of use it or let me know if required an specific permission besides

public async Task isConnected(Activity activity)
{
hasInternetActive = true;
if (!Connectivity.Plugin.CrossConnectivity.Current.IsConnected)
{
bool accessedGoogle = await checkRemoteConnectivity();
if (!accessedGoogle)
{
hasInternetActive = false;
}
}
}

[CircleImage] BackgroundColor issue

When I set a BackgroundColor property CircleImage is no longer circle on Android.
Sample code:

`CircleImage startPomoButton = new CircleImage()
            {
                BorderColor = Color.FromHex(StaticData.ViewStartButtoColor),
                BackgroundColor = Color.FromHex(StaticData.ViewStartButtoColor),
                BorderThickness = 5,
                HeightRequest = 60,
                WidthRequest = 60,
                Source = StaticData.ViewStartButtoImage,
                VerticalOptions = LayoutOptions.Start,
                HorizontalOptions = LayoutOptions.End,
            };`

NavigateTo() fails on some Android devices

Hi James,
the NavigateTo() is broken on some devices (eg. Samsung Galaxy S4 Android 4.2.2)
it is caused by the "(name)" which doesn't seems to be parsed properly by Maps.
After deleting the "(name)" the navigation starts correctly.

https://github.com/jamesmontemagno/Xamarin.Plugins/blob/master/ExternalMaps/ExternalMaps/ExternalMaps.Plugin.Android/ExternalMapsImplementation.cs

I would suggest to change the format string in something like this:
var uri = String.Format("http://maps.google.com/maps?&daddr={0},{1}", latitude.ToString(CultureInfo.InvariantCulture), longitude.ToString(CultureInfo.InvariantCulture)); if (!string.IsNullOrEmpty(name)) { uri += " ("+name+")"; }

Xam.Settings: consider transparent json serialization

On iOS if I try to persist a non-value type, there's an exception thrown in the default case. Is there a reason we can't use Json.NET to serialize to/from string? I know it's kind of encouraging bad design, but still, would be useful in some cases.

Remove Option Feature Request since I Can't put null value to settings on Android

Hello!
I can't addorupdate having null as value (this causes NRE).
Is that by design?

Thank you!

Geolocator fails on WinRT Phone 8.1

I'm getting an exception thrown from CrossGeolocator.Current on a Windows Phone RT 8.1 app:

Operation aborted

You must set the MovementThreshold property or the ReportInterval property before adding event handlers.

This is with the Location capability for the app enabled.

Xam.Geolocator on iOS: GetPositionAsync never returns after a position error

We've noticed that under specific circumstances, the Geolocator plugin can get stuck and never return or throw:

1. Given the geolocator instance is used concurrently by a watcher, i.e. StartListening was called;
2. positioning fails for whatever reason, the PositionError event is triggered;
3. and another client calls GetPositionAsync after that.

My guess is that while the last position is handled here, the error state is not saved, though CLLocationManager doesn't send the same notification again.

Temporarily, it seems that calling StopListening/StartListening in pair before GetPositionAsync works around this.

Vibrate plugin documentation issue

In documentation you have

 In your iOS, Android, and Windows Phone projects please call:

Xamarin.Forms.Init();//platform specific init
Vibrate.Init();

but in Xamarin Android the Vibrate.Init(); not exists. I saw here
https://github.com/jamesmontemagno/Xamarin.Plugins/blob/master/Vibrate/Refractored.Xam.Vibrate.Android/Vibrate.cs

Connectivity Plugin crashes a Foreground Service without activities in the background

Hey James,

You can find a demo solution here: http://1drv.ms/1xvg1lq

Steps to reproduce:

1. Launch app.
2. Open recent apps list
3. Swipe the app to left/right to kill the activity
4. Foreground Service should be running still (notification should still be visible in the notification center).
5. Now turn on or off WiFi (it must connect to an access point)

At this point the service should crash without giving any errors. Debugger should also detach immediately without anything on the output window.

Weird thing is, if the UI isn't killed (if you skip step 3 above) the service does not crash.

You will notice that no code is used in the solution from the Connectivity plugin. It only has to be installed in the project(s). Uninstalling the plugin from the projects fixes the issue.

Cheers,
Ertay

Minimum Android version compatibility for TextToSpeech

Hi,

I'm trying your plugin and when I run the simple example:

CrossTextToSpeech.Current.Speak("Text to speak");

In some devices with Android version lower than 4.4 (KitKat) I get this error:

[] Missing method Android.Speech.Tts.TextToSpeech::get_DefaultLanguage() in assembly Mono.Android.dll, referenced in assembly /storage/sdcard0/Android/data/EverlapsMobile.Android/files/.__override__/Refractored.Xam.TTS.dll

[Settings] PutStringSet Missing

Hi,
I wanted to add the functionality for PutStringSet to the Settings-Plugin. But it can't be resolved.
I've used it in another app before.
I Decompiled ISharedPreferenceEditor and it is missing.
Did that got thrown out or what happened?
I mean you can look at it in the Android Dev Guide. http://developer.android.com/reference/android/content/SharedPreferences.Editor.html#putStringSet%28java.lang.String,%20java.util.Set%3Cjava.lang.String%3E%29

Unified iOS issues

I am getting a on iOS Simulator (iPhone 6 8.0) but not on the iPhone 6 plus "System.IO.FileNotFoundException" - Could not load file or assembly 'monotouch, Version 0.0.0.0'...

Other simulators work or provide another error 'Parameter obj should not be null'.

IsRemoteReachable always False when URL format is invalid

Hi James,

First of all, thank you for sharing this, its great.
I've noticed an annoying feature that should be easily fixed though.
When you do this:

Boolean reachable = await CrossConnectivity.Current.IsRemoteReachable("http://www.google.com", 80, 5000) ? true : false;
Debug.WriteLine("Reachable: " + reachable);

It will always return False, even when there is internet connection and it is reachable.
When you do this:

Boolean reachable = await CrossConnectivity.Current.IsRemoteReachable("google.com", 80, 5000) ? true : false;
Debug.WriteLine("Reachable: " + reachable);

It will work and return True or False depending on your connection.
Could you add the option that http://www.???.com and http://??.com are also supported in the call? You could simply find and remove the first part (http:// or http://www) and would make the API much easier to use, especially for beginners. This isn't documented anywhere and left me searching for an hour just to remove http://www.

Background color Android

If i set a background color, inside a ImageCircle, under iOS is perfect but under Android the background color is a square and goes beyond the limits of the circle.

Add support in Media Plugin to also show video inside an app from a file or web stream.
