title: Android Support Repo 46.0.0 with Android Studio 2.3
body: <p>I updated today my support repository to 46.0.0 as the Android Studio notification popped up.</p>
  
  <p>I go the error below :</p>
  
  <blockquote>
    <p>Error:Execution failed for task ':app:processDevDebugManifest'.</p>
    
    <blockquote>
      <p>Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(25.3.0) from
      [com.android.support:support-v13:25.3.0] AndroidManifest.xml:27:9-31
        is also present at [com.android.support:preference-v7:26.0.0-alpha1]
      AndroidManifest.xml:24:9-38 value=(26.0.0-alpha1).    Suggestion: add
      'tools:replace="android:value"' to  element at
      AndroidManifest.xml:25:5-27:34 to override.</p>

  <p>I updated all my dependencies to use Revision 26.0.0 Alpha 1 from 25.3.0, but it turns out I need to bump the compileSdk from 25 to 26.
  You can't do that if you have AS 2.3, you need to get the unstable alpha/beta version from canary.</p>
  
  <p>This link shows the changes:

  <p>And concerning migrating to the new android O, that's the link:

  <p>It seems using AS stable version will not work with new repository.</p>
  
  <p>How can I go back to the Android Studio Repository Version 45 instead of the new 46?</p>
  
  <p>** Update: The merged manifest shows one of the generated library manifest contains </p>
  
  <pre><code>&lt;meta-data
          android:name="android.support.VERSION"
          android:value="26.0.0-alpha1" /&gt;
  </code></pre>
  
  <p>But since it's a generated file editing is useless, that's why for now I'd stick to rev 45 until the new AS is in stable build</p>
