title: Android Studio isn't showing Build Variants
body: <p>I'm recently struggling with a problem where my Build Variants is not working properly. I can't select variants, there is just a <code>-----</code> on the selection row.</p>

  <p>I have tried to:</p>
  
  <ul>
  <li>delete my .idea folder, invalidate caches and everything</li>
  <li>Sync Project with Gradle Files</li>
  </ul>
  
  <p>My buildConfig Gradle looks like:</p>
  
  <pre><code>  buildTypes {
      debug {
          minifyEnabled false
          resValue "string", "ADMOB_APP_ID", "\"${keystoreProperties["debugAdmobApiKey"]}\""
          resValue "string", "INSTERSTIAL_AD_ID", "\"${keystoreProperties["debugInterstialAdKey"]}\""
      }
  
      release {
          minifyEnabled true
          shrinkResources true
          proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
          resValue "string", "ADMOB_APP_ID", "\"${keystoreProperties["releaseAdmobApiKey"]}\""
          resValue "string", "INSTERSTIAL_AD_ID", "\"${keystoreProperties["releaseInterstialAdKey"]}\""
      }
  }
  </code></pre>
  
  <p>What could be the problem?</p>
