title: Android Studio 3.1.4: java.time.LocalDate" is not supported
body: <p>Android Studio 3.1.4, Java 8, Gradle 4.4.</p>
  
  <p>in my build.gradle:</p>
  
  <pre><code>        compileSdkVersion 26
          minSdkVersion 18
          targetSdkVersion 26
  
        compileOptions {
              targetCompatibility JavaVersion.VERSION_1_8
              sourceCompatibility JavaVersion.VERSION_1_8
          }
  
          implementation 'com.android.support:appcompat-v7:26.1.0'
  </code></pre>
  
  <p>In my POJO</p>
  
  <pre><code>import java.time.LocalDate;
  import java.util.Date;
  public class Product {
      private Date redeemed_date;
      private LocalDate myLocalDate;
  }
  </code></pre>
  
  <p>I must use <code>minSdkVersion 18</code> because it's client requirement.</p>
  
  <p>But when build I get error:</p>
  
  <pre><code>error: Field "myLocalDate" of type "java.time.LocalDate" is not supported.
  </code></pre>
