Package android.support.v7.internal.widget Does Not Exist After Installing Xamarin.Forms.Maps

Asked 2 years ago, Updated 2 years ago, 98 views

  • Windows 10
  • Visual Studio 2015
  • Xamarin version 4.1.1.3
    • installed in Visual Studio
  • Xamarin.Forms/Xamarin.Forms.Maps version 2.3.0.107
    • installed in the project
  • Samsung Galaxy Note Edge (Android 5.0) (I haven't built it yet, so it doesn't really matter)

Installing and building the Xamarin.Forms.Maps Nuget package in the Xamarin.Forms Portable app will result in an error.

There are seven errors like this.How can we solve this problem?
The error is probably related to the Java code, but it is garbled.
Conversion of garbled characters can be inferred from

Error: Package android.support.v7.internal.widget does not exist

That's it.

There seems to be a problem with the Java code.
However, the code has not been tampered with since its initial state (Hello World worked properly when I ran it before I installed Maps).

Also, how do I view the map in Xamarin Reverse Tips Xamarin.Forms? article, and I get the same error when I try setting permissions and describing API keys.

Reference component ○○ not found.

There are also 11 warnings.
Missing Components

  • Bing Maps for C#, C++, or VisualBasic
  • Microsoft Visual C++ 2013 Runtime Package for Windows
  • System.ObjectModel
  • Xamarin.Forms.Core
  • Xamarin.Forms.Maps
  • Xamarin.Forms.Platform
  • Xamarin.Forms.Platform.WinRT
  • Xamarin.Forms.Platform.WinRT.Tblet
  • Xamarin.Forms.Xaml

Yes.
Restoring the Nuget package or rebooting the VS will do the same.This did not appear in the initial state of Hello World either.It appears when you install Maps.

It's hard to find a helpful article because the characters are garbled.
We would appreciate it if you could help us solve this problem.

Additional
Thank you all for your reply.I've tried many things, but it didn't work, so I'm thinking of reinstalling everything on some occasion.
Also, no one seems to have similar symptoms, so I think it's just my deployment mistake.

Please try uninstalling any items other than those listed above, especially those with Android N, API, and Rev 24 installed.

In particular, the Android SDK, packages.config may be different.
Check it out.

Regarding garbled characters, I have installed Xamarin in Windows 10 development environment and use it in a virtual environment.The language setting here is in English, so all errors are printed in English without garbled characters.For your information.

Regarding the reference components,
This error appears to be related to the Windows project configuration.

Delete the project if you don't need it,
Nuget's
for Windows projects, if necessary Verify that Xamarin.Forms, Xamarin.Forms.Windows, Xamarin.Forms.map has been added.
BingMaps~ will also need to set up the SDK for Windows.
