MvvmCross Strange Error: Attribute "MvxBind" has already been defined

Question

Hey i'm a MvvmCross beginner and i try to reproduce this in my own Example-App but i got some strange build errors:

• Error 3 Attribute "MvxBind" has already been defined
• Error 4 Attribute "MvxLang" has already been defined
• Error 5 Attribute "MvxTemplate" has already been defined
• Error 6 Attribute "MvxItemTemplate" has already been defined
• Error 7 Attribute "MvxDropDownItemTemplate" has already been defined
• Error 8 Attribute "MvxSource" has already been defined

There is no other deifinition of these Attribute's...

This my "MvxBindingAttributes.xml":

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <declare-styleable name="MvxBinding">
    <attr name="MvxBind" format="string"/>
    <attr name="MvxLang" format="string"/>
  </declare-styleable>
  <declare-styleable name="MvxControl">
    <attr name="MvxTemplate" format="string"/>
  </declare-styleable>
  <declare-styleable name="MvxListView">
    <attr name="MvxItemTemplate" format="string"/>
    <attr name="MvxDropDownItemTemplate" format="string"/>
  </declare-styleable>
  <item type="id" name="MvxBindingTagUnique"/>
  <declare-styleable name="MvxImageView">
    <attr name="MvxSource" format="string"/>
  </declare-styleable>
</resources>

Would be cool if someone could help me :)

Or any other way/tutorial with android tabs and MvvmCross.

Are all you MvvmCross packages the same version? Also, try doing a clean build. Make sure all your Android SDK items are up-to-date. – Bonefish

Hey thx for the Comment! All Cirrious.MvvmCross.Droid.XX packages are the same Runtime version (v2.0.50727) All other are (v4.0.30319) – Alaster

this a problem? I have used this command to add the packages: Install-Package Cirrious.MvvmCross.Droid.Support.V4 -Pre – Alaster

Answer 1

The newer 3.5.2 and 4.0.0 packages now include MvxAttributes.xml internally. So just remove it from your own Resource\values folder.

Hey thx for the answer, but if i remove the file there are new build-errors: Error 2 No resource identifier found for attribute 'MvxBind' in package 'TestApp.UI.Droid' – Alaster

Clean your project, the Resource.Designer.cs file is most likely still looking at something old. – Clockwise

Answer 2

You need to change the local namespace to:

xmlns:local="http://schemas.android.com/apk/res-auto"
