# Steps to reproduce
1. Update Android SDK Tools, Android SDK Platform tools to at least 26.0.0 and Android SDK Build-Tools to latest version
2. Build some of my solution Android projects after updating VS 2017 to 15.4.
Solution contains 26 projects with 13 PCL and 13 Android projects.
Failing projects settings does not have visible configuration changes from the ones that builds successfully (compared .csprojs). I think that all failing projects tends to be "bigger" (> 5 classess) than the ones that builds successfully (< 5 classess).

# Expected behavior
Projects builds successfully as they were on version 15.3.

# Actual behavior
Projects fails to build with strange errors attached below.

# Test environment (full version information):
- Windows 8.1 Pro x64
- VS 2017 Enterprise 15.4
- latest Android SDK tools
Comment 1 David Platt 2017-10-15 14:01:52 UTC
Just reporting that I have the exact same bug. I have it on my VS Community for Mac, v7.2 Build 636. And also on my VS Community 2017 for Windows, v 15.4.0 . In both cases, it appeared immediately after downloading and installing that version
Comment 2 Jon Dick 2017-10-16 18:16:04 UTC
What version of Android support libraries are installed when seeing this?
Comment 3 David Platt 2017-10-16 18:24:05 UTC
I have Xamarin.Android SDK V 8.0.0.33 on my VS Windows installation. Android SDK 25.2.5 . 

On my Mac it's Xamarin Android 8.0.0.33 and Android SDK 25.2.5
Comment 4 Jonathan Pryor 2017-10-16 18:27:58 UTC
@David: @Jon Dick is asking about the version of the *Support* libraries that your App is using:

https://www.nuget.org/packages/Xamarin.Android.Support.Vector.Drawable

An issue with injecting `--no-version-vectors` was fixed in Xamarin.Android.Support.Vector.Drawable ~7 months ago:

https://github.com/xamarin/AndroidSupportComponents/commit/231d1c8bf8cbb8d356c6033ed6fd47c6a9fe402e
https://github.com/xamarin/AndroidSupportComponents/blob/master/support-vector-drawable/nuget/merge.targets#L38-L48
Comment 5 David Platt 2017-10-16 18:38:59 UTC
It it was fixed 7 months ago, should that fix not then be in the most recent update? And probably the one before that? Why am I encountering it now?

Also, check the link to the forum in the first posting in this chain. On that forum posting, you will see a screen shot with 7 other errors, often in nonsense or semi-sense words. The original poster has them, and I have them as well. Any ideas for a fix?
Comment 6 Jon Dick 2017-10-16 18:49:04 UTC
@David we're trying to understand what version of the Xamarin.Android.Support.Vector.Drawable nuget package you have installed in your project.  I believe you must be using an older version of the package which doesn't have the fix, but I want to be sure so that we can diagnose the problem further if this is not actually the case.
Comment 7 David Platt 2017-10-16 18:49:40 UTC
Of course. Where would I look to find that information?
Comment 8 Jon Dick 2017-10-16 18:52:57 UTC
Check your project's packages.config file, it should list all of your installed nuget packages and the versions installed.  

It might help if you can also share the contents of your .csproj file.

Comment 10 Jon Dick 2017-10-16 19:01:08 UTC
Ok, looks like you're using an old version of the Xamarin Support library packages.

I'd recommend upgrading anything Xamarin.Android.Support.* to be version 25.4.0.2.  

Fair warning, Xamarin.Android.Support.v7.CardView will probably need to be explicitly updated (most others should all update once you update Xamarin.Android.Support.Design since the are all dependencies of that package).
Comment 11 David Platt 2017-10-16 20:08:18 UTC
Working on this. Have to go out to teach now. Will resume first thing tomorrow. It may be easiest just to generate new Android project and copy source files over.
Comment 12 Maciek 2017-10-16 21:12:15 UTC
I have updated all Support packages and errors are gone and app builds. However, my app misbehaves now (eg. my Custom buttons dont get click events now), but I didn't do deeper research yet.

What I know is that I had Support packages downloaded few months ago along with Xamarin.Forms 2.3.4.231, that is versions 23.x and they were working fine until recent Visual Studio 15.4 update.

Could you please explain why that errors came out just after 15.4 update? I do not want to update my NuGets yet (especially Xamarin.Forms) as having bad experiences with recent Xamarin and Xamarin.Forms updates makes me uncertain of other hidden bugs that might come out in my product over time after that updates.
Comment 13 Jon Dick 2017-10-17 13:39:55 UTC
The fix has been released for several versions now of the Android Support Vector Drawable support library, so this is the supported and recommended fix.

You could work around this manually by removing the:

<Import Project="..\..\packages\Xamarin.Android.Support.Vector.Drawable.23.3.0\build\Xamarin.Android.Support.Vector.Drawable.targets" Condition="Exists('..\..\packages\Xamarin.Android.Support.Vector.Drawable.23.3.0\build\Xamarin.Android.Support.Vector.Drawable.targets')" />

from your .csproj project files and adding this directly into the project file as its replacement:

<!-- Adds an argument to the call to aapt to support vectors -->
      <PropertyGroup Condition=" '$(AndroidResgenExtraArgs)' != '' AND !$(AndroidResgenExtraArgs.Contains('--no-version-vectors'))">
        <AndroidResgenExtraArgs>$(AndroidResgenExtraArgs.TrimEnd(' ')) --no-version-vectors</AndroidResgenExtraArgs>
      </PropertyGroup>
      <PropertyGroup Condition="'$(AndroidResgenExtraArgs)' == ''">
        <AndroidResgenExtraArgs>--no-version-vectors</AndroidResgenExtraArgs>
      </PropertyGroup>
Comment 14 Jeff H 2017-12-13 15:52:50 UTC
In our particular instance of this issue, the cause was duplicate imports of Xamarin.Android.Support.Vector.Drawable for different versions

<Import Project="..\packages\Xamarin.Android.Support.Vector.Drawable.24
and 
<Import Project="..\packages\Xamarin.Android.Support.Vector.Drawable.25
Comment 15 Nikita 2018-01-11 08:48:35 UTC
Hey, I'm very happy that I found your discussion, I have a similar error, "--no-version-vectors", but slightly in a different context.

Here are links to the discussions I've created:
https://forums.xamarin.com/discussion/comment/313641#Comment_313641

When I run the build project, I get a "Package_resource does not exit" error, using the diagnostic mode, I found the following log:

In diagnostic mode, I have this line, just before the error. Reading forms people say to pay attention to the very end of this line.
