Recently, I have been getting this error a lot and from some research, I got to know that the cause for it is the Xamarin.Build package.
The error text is as follows:
The "User7ZipPath" parameter is not supported by the "XamarinDownloadArchives" task. Verify the parameter exists on the task, and it is a settable public instance property.
I have tried the solution here and here but nothing helped.
My configuration is as follows:
Xamarin version: 4.7.10.38
Visual Studio 2015
The Error occurs when I update the xamarin build NuGet package, If anyone has a solution to this problem please help me.
Thanks.
At last after all this time I was able to solve this problem.
The problem was with Xamarin.Build.Download package.
Now this package had a problem in version 4.7 where it is unable to find the XamarinDownloadArchives task.
I checked a lot of places and for the answer but nothing seemed to help with this issue after that I removed the bin, obj folders for all my projects.
And Updated my Xamarin.Build.Download package to version 0.4.11 and everything started working.
I hope this helps someone else, In case of any queries related to this issue feel free to comment.
Finally! I've come with a solution. The problem was in the Xamarin.Build.Download package, v0.4.0. It was a annidated dependency (in iOS) of Xamarin.Forms.GoogleMaps v2.2.1.
Updating Xamarin.Forms.GoogleMaps to v2.3.0 (the most recent version as of today) solves the issue. Make sure to clean the solution after update NuGet dependencies, though.

I'm in the process of migration a XamarinForms 5 app to MAUI and the latest error I get is
The Java type `mono.android.support.v4.media.session.MediaSessionCompat_OnActiveChangeListenerImplementor` is generated by more than one managed type
Searching online, so far I think it is because the app is using Android.Support.V4 when it should only be using AndroidX, causing the duplicate to be generated as AndroidX replaces Support.V4.
However I cannot figure out how to remove the Support.v4 package because the only reference to it is an implicit reference by an SDK which I cannot remove ( see screenshot below)
The project file (MAUI) only has these package references
Any help greatly appreciated.
Thanks
I'll answer my own question as I managed to figure out the issue after a solid several hours long session.
No packages needed to be removed. Somehow I had managed to install a version of
Birdie.Plugin.FirebasePushNotification from 2020 , instead of `Plugin.FirebasePushNotification', the current version.
The solution was to remove that old package and install the correct once which made the error go away.
I am trying to release my application so I can distribute, however when I try to build my application I get this error message.
Can't resolve the reference 'CoreLocation.CLAuthorizationStatus CoreLocation.CLLocationManager::get_AuthorizationStatus()', referenced from the method 'System.Void Xamarin.Essentials.Permissions/LocationWhenInUse/ManagerDelegate::DidChangeAuthorization(CoreLocation.CLLocationManager)' in 'Xamarin.iOS, Version=0.0.0.0, Culture=neutral, PublicKeyToken=84e04ff9cfb79065'. (MT2101)
Everything works fine when I am in debug mode. I can test on my phone and the emulator but when I think I am good to release I get hit with the error above. I read in the docs, looks like this happens when someone is trying to request access to the location information. However the only thing I can think I am requesting is the current UTC time and dateTime.Now for local time which I don't think has anything to do with the location of the device/user.
That is the only major thing I have changed from my last release, that and I updated some nugget packages. I had issues when I tried to release last time and someone on here was able to help me figure it out, it was a nugget package creating a conflict with another one. I want to think it is my Xamarin.Essentials nugget but I'm not sure. Has anyone else seen this? I saw some people requested help from Xamarin forums but the solution they explained I did not find helpful.
they said to do the following.
Updatring
pool: vmImage: 'macOS-latest'
and removing
- script: sudo $AGENT_HOMEDIRECTORY/scripts/select-xamarin-sdk.sh 6_8_0
I found the same issue in this thread:
And this should be fixed in #1606
The solution is using the latest Xamarin.Essentials/1.6.1-preview1.
If you can' switch to the preview, then you will have to install the latest version of Xamarin.iOS on the agents.
Recently the SPM has started to give me errors. Was working before.
I'm trying to use the AlamofireImage library but xcode fails to resolve de dependency and doesn't give any good explanation.
Does anybody know why and how to make it work?
this was once happened to me, maybe you can try to go ahead to File > Swift Packages > Update to Latest Package Versions. Let's see if that works
I ran into a similar issue when I was trying to arrange the files inside the project folder, and when I put them back to their old position the problem was resolved and the app run successfully.
I found something that's not ideal, but works for now. In your main xCode project file, go under Project not Target and find Package Dependencies. After finding it, remove the SDK, and then right click on the name of your project and add a package. This time when adding Firebase, use Minor version. It should hopefully resolve and install.
So I enabled proguard on one of my application. I had some problems with it but I solved them all ( had to update proguard, make a symlink of android sdk without spaces )
Now I enabled pro guard on another application and i'm constantly getting this error:
The "Xamarin.Build.Download.XamarinBuildAndroidAarProguardConfigs" task could not be loaded from the assembly C:\Users\xxx\Desktop\xxx oud\packages\Xamarin.Build.Download.0.4.6\build\Xamarin.Build.Download.dll. Confirm that the <UsingTask> declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask.
Anybody knows a way to solve this? Not sure what more I could add
I resolved my issue by restarting my computer
Edit: It seems restarting visual studio might be enough to resolve the problem
Restarting Visual Studio or my computer didn't work for me. The correct fix is to modify the package version of Xamarin.Build.Download to something that works.
For me, it meant changing the packages that referred to version 0.4.7 to 0.4.3.
It seems that a lot of people have had trouble with 0.4.7.
I started a new default working project in xamarin and I added the dll references for Xamarin.Android.Support.V4 and Xamarin.Android.Support.V7.AppCompat and I am getting errors.
Error: package android.support.v4.app.FragmentManager does not exist

Error: package android.support.v4.content.Loader does not exist
android.support.v4.content.Loader.OnLoadCompleteListener

What have I done wrong?
You needed to actually install the support library. MonoDroid has .NET bindings for it, but the underlying java can't build without it, of course. Here are instructions for getting the support library and instructions for hooking it up to a MonoDroid project.

This might be related to this or this, which were solutions to common problems in the rev. 22 update.
try calling it with this:
using Android.Support.V4;
I was reading another post in the xamarin forms with the same issue and this worked for me. I spent maybe an hour trying to figure out what to do and the guy I ran into said just to:
clean the solution,
rebuild it,
then it should be fixed.
Assuming the packages are still installed
