Cannot install Xamarin.Android.Support.v4

Posted by: admin June 15, 2020 Leave a comment

Questions:

I am trying to install this particular package into my program and get the following error:

Error Could not install package ‘Xamarin.Android.Support.Compat
24.2.1’. You are trying to install this package into a project that targets ‘MonoAndroid,Version=v6.0’, but the package does not contain
any assembly references or content files that are compatible with that
framework. For more information, contact the package author.

What exactly is my project suppost to target and how do I make this change? I already installed android 7, however I cannot even target that for some strange reason. Not even if I make a new project I can’t target that.

How to&Answers:

This package requires MonoAndroid70 to be installed. Thus you need to ensure your TargetFrameworkVersion is set to a minimum of Android 7.0. You will need to install API 24(7.0) and change the version.

For those interested in how you would find this, you can download the .nupkg from NuGet:

https://www.nuget.org/api/v2/package/Xamarin.Android.Support.v4/24.2.1

You can then extract the .nupkg and view the lib folder which will show you what the library supports.

Answer:

I recommend below steps

1- download a previous version (

<package id="Xamarin.Android.Support.v4" version="23.1.1.1" targetFramework="monoandroid60" />

)

2- delete the following local folder “..\AppData\Local\Xamarin”

3- Build the droid project (it will take some times)

Finally, no more issues with these xamarin support packages.

Cheers UP!

Answer:

The solution:

  • Try to update your xamarin visual Studio after you will install it and you will get monoandroid v7
  • update your android sdk Api 24 or api 25

I think it will help you.

Answer:

I removed from the Android SDK all API dependencies 23, ie Android 6.0 and installed from 7.0 and 7.1 (AP 24 and 25).

Clean and Rebuild the project.

Done that, it worked correctly.
Hope this helps.
