title: Incompatible types. Require: Object, Found: String?
body: <p>I am trying to use Google Sheets API for Reading and Writing on my App.</p>
  
  <p>(Now I am reading <a href="https://developers.google.com/sheets/api/guides/values" rel="nofollow noreferrer">Google Sheets API Tutorial documents</a>)</p>
  
  <p>I got an error which said</p>
  
  <h3>ERROR</h3>
  
  <pre><code>Incompatible types.
  Required: List&lt;java.util.List&lt;java.lang.Object&gt;&gt;
  Found: List&lt;java.util.List&lt;java.lang.String&gt;&gt;
  </code></pre>
  
  <h3>Code</h3>
  
  <pre><code>List&lt;List&lt;Object&gt;&gt; values = Arrays.asList(
      Arrays.asList(
          // Cell values ...
          "apple", "banana"
      )
      // Additional rows ...
  );
  </code></pre>
  
  <p>I think that String has Object properties because of <code>public final class String extends Object</code> in Java. (See <a href="https://docs.oracle.com/javase/7/docs/api/java/lang/String.html" rel="nofollow noreferrer">this oracle documents</a>) But, I am wondering why I got error. And I don't know how to solve this.</p>
