Xamarin.Forms iOS Build Failure
Have a Xamarin.Forms project with net standard 2 XF assembly driving UWP and iOS apps. Running XF v3.4.0.1008975 on Visual Studio Community 2017 15.9.4 on the latest Windows 10. Mac that is performing the build is running Mojave 10.14.1 and Visual Studio Mac 7.7.2 (Build 21).
UWP application builds and runs with no problems. iOS build was running without any problems up to about two weeks ago.
Now the iOS build throws out several MT0136 warnings for assemblies that are referenced by the net standard assembly and then crashes out with MT2001 that tells me that encountered an error while processing references of the net standard 2 assembly. This is after the detection of the signing identity output and the linker setting is do not link (debug mode).
Any guidance is greatly appreciated. Note that I already tried common approaches involving deleting bin/obj directories and mac build cache cleanup.

Which version of NDK should we use? not latest?
I was told that we should always use the version NDK according to below
https://github.com/xamarin/xamarin-android/blob/master/build-tools/android-toolchain/android-toolchain.projitems
as it seems 14b version is used, we can use highest 14b? which is from march 2017, pretty old. why is it? I tried used 18b today latest version and my project works fine in debug mode and compiles also fine in release mode. Problem occurs when i want to install the app in release more or try to create a package. I get this exception
Error XA5101: C compiler for target Arm was not found. Tried paths:
"C:\Android\android-ndk-r18b\toolchains\arm-linux-androideabi-4.9\prebuilt\windows-x86_64\bin\arm-linux-androideabi-gcc.exe;
C:\Android\android-ndk-r18b\prebuilt\windows-x86_64\bin\gcc"
So, can someone confirm from xamarin team if we can rely on android-toolchain.projitems file or we can simply use latest NDK, maybe my exception is something else?

Can't debug on android devices in visual studio
Since I have started with Xamarin I have had problems getting the android debugging to work.
Every time I deploy a Xamarin Forms (PCL) project to my phone (LG G Flex 2, Android 5.1 lollipop), the deploy succeeds, enters debug mode for about 6 or 7 seconds, then goes out of the debug mode without any errors and closes the app on my phone. The app is installed however and I can use it afterwards.
I have a laptop and a pc, both running Visual Studio 2015 update 2, both have the same problem with every project.
These problems only occur when debugging for Android, not for Windows or Windows Phone, (no idea about IOS).
The output tab (Debug) only shows:
Android application is debugging. Couldn't connect to logcat, GetProcessId returned: 0
That last line is only showed on my laptop and not on my pc.
The output from Xamarin Diagnostics :
[D:RunShellCommand]: LGH955833bfe56 getprop [D:RunShellCommand]: LGH955833bfe56 getprop [D:RunShellCommand]: LGH955833bfe56 date +%s [D:RunShellCommand]: LGH955833bfe56 setprop "debug.mono.extra" "debug=127.0.0.1:8865:8866,timeout=1464533426,loglevel=0,server=y" [D:RunShellCommand]: LGH955833bfe56 am start -a "android.intent.action.MAIN" -c "android.intent.category.LAUNCHER" -n "Project.Droid/md5ebb414a62e6ccdc1a237d6523954780b.MainActivity" [D:RunShellCommand]: LGH955833bfe56 ps [D:RunShellCommand]: LGH955833bfe56 am force-stop Project.Droid [D:RunShellCommand]: LGH955833bfe56 setprop "debug.mono.connect" ""
As you can see it forces the application to close for some reason, but i have no idea what's causing it.
On my pc the output is about the same except for 2 extra lines concerning the logcat.
Any idea on how to fix this?

ToolbarItem with Order="Secondary" not functional in iOS?
It is not a problem that they appear as Buttons (???) inbetween the Title and the ListView in iOS. But when I tap them the Clicked events are not fired.
Is that normal? How do I make them functional in iOS?

Three questions on ContextAction's behavior
First, Aren't ContextAction's available in UWP at all?
Second, I see the sliding for ContextAction buttons be visible is available in iOS only. Can't we get sliding for actions in Android?
Third, In iOS they appear only on sliding from right to left. I don't find any property to set to make them appear while sliding from left to right?
How can I get around these two issues?

Request permissions not working within PermissionsPlugin
For my Xamarin.Forms-App I'm using the PermissionsPlugin v2.0.1.
If no permission is granted, I want to request the user to do so by CrossPermissions.Current.RequestPermissionsAsync(Permission.Storage)
The problem is that the function always returns Unknown instead of requesting the user for the permission. One time, it worked...but I don't know what I changed that it's not working anymore..
Here my code:
MainActivity.cs (Android-project)
public override void OnRequestPermissionsResult(int requestCode, string[] permissions, Permission[] grantResults)
{
base.OnRequestPermissionsResult(requestCode, permissions, grantResults);
PermissionsImplementation.Current.OnRequestPermissionsResult(requestCode, permissions, grantResults);
}
AndroidManifest.xml
<uses-sdk android:minSdkVersion="15" android:targetSdkVersion="25" />
<uses-permission android:name="android.permission.CAMERA" />
PermissionsExample.xaml.cs
[XamlCompilation(XamlCompilationOptions.Compile)]
public partial class PermissionExample
{
public PermissionExample()
{
this.InitializeComponent();
}
private async void Button_OnClicked(object sender, EventArgs e)
{
var requestedPermissions = await CrossPermissions.Current.RequestPermissionsAsync(Permission.Camera);
var requestedPermissionStatus = requestedPermissions[Permission.Camera];
await this.DisplayAlert("", $"Permission: {requestedPermissionStatus}", "ok");
}
}
Thanks for your help!

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.
