title: Execution failed for task :app:processDebugManifest Android Studio 2.3.3
body: <p>I'm getting a compile error after adding <strong>CardView</strong> and <strong>RecyclerView</strong> dependencies, I've checked every post but no one seems to solve this case.</p>
  
  <p>Error:</p>
  
  <blockquote>
    <p>Error:Execution failed for task ':app:processDebugManifest'. Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(25.3.1) from [com.android.support:appcompat-v7:25.3.1] AndroidManifest.xml:27:9-31
        is also present at [com.android.support:cardview-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>
