I downloaded Xamarin from the website and the installation fails after downloading the android SDK manager, I retried a few times, still no positive results. Should I uninstall Xamarin, if so, how? What should I do, I want to code a IOS and Android application.

I wanted to run the program I just created, but it gave an error message and the android emulator was not installed.
According to my research, it should be android sdk, unfortunately I can't find anything.
I have been on this for about 2 months before I turned here for assistance. I have VS 2019 and have xamarin installed. When I open a xamarin project, I get 1 warning and 1 error.
The warning:
Could not find android.jar for API Level 28. This means the Android SDK platform for API Level 28 is not installed. Either install it in the Android SDK Manager (Tools > Open Android SDK Manager...), or change your Xamarin.Android project to target an API version that is installed. (C:\Program Files (x86)\Android\android-sdk\platforms\android-28\android.jar missing.)Test.Android
The error:
The project Test.Android is missing Android SDKs required for building. Double-click on this message and follow the prompts to install them.
Note: In the bottom right corner, by refresh, it does say offline mode.
I have tried every solution I could find on here (and other sites). My android SDK manager is showing up fine, the only one on there, however, is Android 8.1 - oreo API Level 27. I have verified the auto install sdk's were on, I have ran as administrator, all with no luck.
Any help is greatly appreciated!
Good day, I'm using visual studio 2017 , xamarin iOS. I'm trying to implement ios push notifications with firebase, so I've installed Xamarin.Firebase.iOS.CloudMessaging and it's dependecies.
But the project is not building and I'm getting errors on each package :
"Download failed. Please download https://dl.google.com/dl/cpdc/15a4dd6c971f8bbf/FirebaseAnalytics-4.0.4.tar.gz to a file called C:\Users\Me\AppData\Local\XamarinBuildDownloadCache\FAnlytcs-4.0.4.tgz."
I've tried to add both rar and tgz files into the folder, no difference. What am I missing?
My Xamarin development was working fine yesterday and is now showing this error message when trying to run the project:
error MT1108: Could not find developer tools for this 10.0.2 (14A456)
device. Please ensure you are using a compatible Xcode version and
then connect this device to Xcode to install the development support
files.
I have updated Xcode to 8.1, Xamarin Studio is on the latest stable build and I've upgraded to macOS Sierra, but I still have this issue. Colleagues with the same dev environment as me are still able to run the project fine. I'm also able to open a different iOS project with the same settings and it will deploy to the phone fine.
Other things I've tried:
Complete uninstall/re-install of Xamarin Studio.
The Alpha build of Xamarin Studio.
So this worked for me:
Change the debug configuration to: Debug | iPhoneSimulator
Run the solution
Change the debug configuration back to: Debug | iPhone
Run the solution
I have Visual Studio 2015 RC. When I open a console app or a Windows Phone 8 Silverlight project, everything works fine, I can use Nuget without problems.
When I open a Universal App project (Windows 8.1 + Windows Phone 8.1), Nuget breaks. When I open the Nuget console, I see
When I try to install a Nuget package using the Nuget GUI, I get the same error.
One more strange thing. When I open VS2015 RC without any projects and open the Nuget console, I do not get the error. Then when I open my Universal App project, the error appears.
I am pretty sure it is connected to the Universal App project.
I testes the Universal App project in VS2013 and everything works fine there, no problems with Nuget.
I tried all the steps in installing nuget package "same key has already been added." but it did not help. I guess it is because another folder may be corrupted in my case.
Happens to me on two separate machines, both run Windows 8.1 Pro, one has only VS2015 RC and on has both VS2013 Pro and VS2015 Pro.
I have had the same problem with VS2013 from time to time. While I don't have the exact steps to resolve here, the following summarizes what worked (it may be over kill).
use the package manager to remove all packages
remove the library binding section in the app config
re-add the packages via the package manager
It is a windows machine, you may need to restart visual studio between each step.
