title: Resolve Manifest Merger Failed error - tools:replace
body: <p>A conflict on Android Support library versions 25.3.1 and 26.0.0-alpha1 is causing a manifest merger failed error when performing a Gradle sync.</p>
  
  <p><strong>How can we use a  tag with tools:replace property as Android Studio / gradle suggests to fix this error?</strong></p>
  
  <p>(i.e. what is the exact syntax within AndroidManifest.xml to force usage of support:design:25.3.1 instead of 26.0.0-alpha1 which an included library is using)</p>
  
  <p>This is the error Gradle is producing:</p>
  
  <pre><code>Error:Execution failed for task ':app:processDebugManifest'.
  &gt; Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(26.0.0-alpha1) from [com.android.support:support-v4:26.0.0-alpha1] AndroidManifest.xml:27:9-38
      is also present at [com.android.support:design:25.3.1] AndroidManifest.xml:27:9-31 value=(25.3.1).
      Suggestion: add 'tools:replace="android:value"' to &lt;meta-data&gt; element at AndroidManifest.xml:25:5-27:41 to override.
  </code></pre>
