title: Different code in different build variant
body: <p>I have two build variants in my app, one is an standard app edition and the second one is a customization app.</p>
  
  <pre><code>productFlavors {
          customConfig {
              minSdkVersion 14
              applicationId 'es.com.custom'
              targetSdkVersion 22
              versionCode 3
              versionName '3.0.0'
          }
          standard {
              minSdkVersion 14
              applicationId 'es.com.standard'
              targetSdkVersion 22
              versionCode 3
              versionName '3.0.0'
          }
  </code></pre>
  
  <p>For the customization I have to implement new features, but just for the customization, so those new features will be not available on the standard version. I am not sure what i have to do.    </p>
  
  <p>1.- Two classes , one with the standard requirements and one with the custom requirements<br>
  2.- In the standard class do something like:</p>
  
  <pre><code>  if (getPackageName()==customConfig )
      // do the custom things
      else
      //do the standard things
  </code></pre>
