What is the best way to do video conferencing in Xamarin Forms?
I'm looking at how to do video conferencing in IOS and Android,
Is there any SDK to do this? Or should it be done natively on each plataform?
Which is the best route?
I searched in the forum, but found only very old answers. And nothing concrete about the operation.
If someone has done something like this, please share it with us.
Thank you all

TokBox OpenTok SDK for Xamarin Forms.
Hi,
I have made proof of concept app for a video chat application in Xamarin Native using the below nuget packages (it works like a charm the source code is done by provider available here https://github.com/DreamTeamMobile/Xamarin.Opentok.Samples/tree/code-improvements)
https://www.nuget.org/packages/Xamarin.OpenTok.Android/
https://www.nuget.org/packages/Xamarin.OpenTok.iOS/
These nuget packages are basically a port of the native iOS/Android SDK's by TokBox for Xamarin, Created by DreamTeamMobile. I want to make use of them to for creating a Xamarin Forms application, I need some guidance how I can make the same functionality available to a Forms Project, considering that the package provider doesn't provides Xamarin Forms implementation. Would custom renderers help here.

Weird error while using MSBuild to get APK
Hi,
I am trying to make an APK from cmd line via this command:

Linking C# to additional Objective C header file.
Hi guys, I have created a UI on Mac OS recently (Not phone Apps), and I am trying to link it to an additional Objective C code.
The source of this approach is really limited as all I found was about phone apps development. Hence I am trying to verify whether my concept is do-able or not. My Approach is as below :
My solution consist of Objective C and C#, which is linked internally when I created a new solution. These are done in the background by developers of these templates, where C# is the main sequence of the whole User Interface operations. Now I have created an Objective C file (externally), with all the functions to be called in its header file. I would love to link my UI (C# and Objective-C) to this Objective C file, the similar way developers used to link C# to Objective C.
This is the only link related to the subject that I am looking for, unfortunately it is mainly about phone Apps development.
https://docs.microsoft.com/en-us/xamarin/ios/platform/binding-objective-c/index
Below are small parts of my code /:
UI code:
MainViewController.designer.cs (Visual Studio for Mac)
using Foundation;
using System.CodeDom.Compiler;
namespace Main
{
[Register ("MainViewController")]
partial class MainViewController
{
[Outlet]
AppKit.NSButton btnConnect { get; set; }
[Action ("btnSubWindow:")]
partial void BtnPopOut (AppKit.NSButton sender);
}
void ReleaseDesignerOutlets ()
{
if (btnConnect != null) {
btnConnect.Dispose ();
btnConnect = null;
}
}
}
MainViewController.m (Xcode)
#import "TestLauncherViewController.h"
@implementation TestLauncherViewController
@synthesize btnConnect = _btnConnect;
- (IBAction)btnSubWindow:(NSButton *)sender {
}
@end
MainViewController.h (Xcode)
#import <Foundation/Foundation.h>
#import <AppKit/AppKit.h>
@interface TestLauncherViewController : NSViewController {
NSButton *_btnConnect;
@property (nonatomic, retain) IBOutlet NSButton *btnConnect;
- (IBAction)btnSubWindow:(NSButton *)sender;
@end
From here, we know that Objective-C has been linked to C#, and ready to be altered from C#.
Below are part of my externally created Objective C file:
Addition.h
@interface Addition : NSObject{
int progress;
Status state;
}
-(instancetype)initWithIP:(char*)ipaddress andUIdelegate:(id)del;
-(void)startToRun;
-(int)Multiplication;
@end
I am trying to use C# to access this Objective C header file to search for the entry point of any functions that I wish to call.
Please tell me if my concept is doable or not.
If do-doable :
Please provide me some guidance to achieve this approach.
Thank you in advance.

Unable to change ListView.ItemTemplate in code behind in iOS of a Xamarin.Forms app
First I thought it was due to ToolbarItem with Order="Secondary" was not functional in iOS. Unfortunately I didn't put breakpoint and debugged it when I posted the above thing.
But after putting the breakpoint and debugging I found that the setting ItemTemplate in an event was not effective. The pros may tell me if it is a bug.
First, the postings by @NMackay and @ClintStLaurent in this thread confirmed that the way that I was accessing the StaticResource in the code is correct.
Then I found this post on StackOverflow which hinted me what may be wrong. It was mentioned that one has to refresh the ListView several times before the chanted ItemTemplate is effective. And I found that I will have to pull-to-refresh as many times as the number of rows visible. Still the new Itemtemplate is not applied to the top most item.
My code is as below:
<ContentPage.Content>
<StackLayout>
<ListView x:Name="ItemsListView"
ItemsSource="{Binding ToDoPlusItems}"
VerticalOptions="FillAndExpand"
HasUnevenRows="true"
RefreshCommand="{Binding LoadItemsCommand}"
IsPullToRefreshEnabled="true"
IsRefreshing="{Binding IsBusy, Mode=OneWay}"
CachingStrategy="RecycleElement"
ItemTemplate="{StaticResource ItemTemplateNonFramed}">
<ListView.GestureRecognizers>
<TapGestureRecognizer Tapped="GstrDoubleTapListItem_Tapped"
NumberOfTapsRequired="2" />
</ListView.GestureRecognizers>
</ListView>
</StackLayout>
</ContentPage.Content>
<ToolbarItem Text="Show Abridged"
Clicked="ShowAbridged_Clicked"
Order="Secondary" />
<ToolbarItem Text="Show More"
Activated="ShowMore_Clicked"
Order="Secondary" />
private void ShowAbridged_Clicked(object sender, EventArgs e)
{
ItemsListView.ItemTemplate = (DataTemplate)this.Resources["ItemTemplateNonFramed"];
}
private void ShowMore_Clicked(object sender, EventArgs e)
{
var template = this.Resources["ItemTemplateFramedShort"] as DataTemplate;
ItemsListView.ItemTemplate = template;
}
