body: <p><img src="https://i.stack.imgur.com/SFU3p.png" alt="Screenshot">
  I add the wear module into the existing application, and provide the support of another module (that handles the Auth and Network task). When we build, gradle shows the following error:</p>
  
  <blockquote>
    <p>duplicate resource attr/textSize with Config.  </p>
  </blockquote>
  
  <p>Our Android Wear dependencies:</p>
  
  <ol>
  <li>compile 'com.android.support:wear:27.0.0'</li>
  <li>api project(':core')// Network and Encryption related module </li>
  <li>provided 'com.google.android.wearable:wearable:2.1.0'</li>
  <li>compile 'com.google.android.support:wearable:2.1.0'</li>
  </ol>
  
  <p>If we remove the core module its not showing any error,  </p>
