title: Manifest merger failed error
body: <p>I am in the process of moving my current projects huge application into Android Studio and Gradle. I am currently stuck on the following issue:</p>
  
  <pre><code>Error:(87, 9) Execution failed for task ':App:processDebugManifest'.
  &gt; Manifest merger failed : Attribute application@label value=(@string/app_label) from AndroidManifest.xml:87:9
      is also present at ANDROID_APPLICATION:Library:unspecified:9:18 value=(@string/app_name)
      Suggestion: add 'tools:replace="android:label"' to &lt;application&gt; element at AndroidManifest.xml:82:5 to override
  </code></pre>
  
  <p>I have tried adding the following attributes to the main <code>AndroidManifest.xml</code> file:</p>
  
  <pre><code>tools:replace="android:label, *App Name*"
  tools:replace="android:label, @string/app_label"
  tools:replace="android:label"
  </code></pre>
  
  <p>None of these attribute definitions works. What am I doing wrong?</p>
