<h2 id="open-jdk">Platform Migration toward OpenJDK 8</h2>

<p>

  Android N moves Android’s Java language libraries to an OpenJDK-based

  approach, creating a common code base for developers to build apps and

  services. If your app depends on a private implementation of Java or

  unspecified behavior, you should be aware of these known issues:

</p>

<ul>

  <li>The {@code ArrayList} private field array is removed.

    <p>

      If your app, or a library it used, was dependent on a private field of

      the <code>ArrayList</code> class, you may encounter an exception such as:

    </p>

<pre class="no-pretty-print">

java.lang.NoSuchFieldException: No field array in class Ljava/util/ArrayList;

</pre>

  </li>

  <li>Calling a {@code Comparator} implementation with equal elements is

  possible.

    <p>

      You can now call implementations of Comparator to compare an element to

      itself. However, doing so may cause problems if the Comparator expects to

      be called only with unique arguments.

    </p>

  </li>

  <li>Crypto security provider has been removed.

    <p>

      You should only call to the Java Cryptography Extension (JCE) APIs with a

      provider listed if the provider is included in the code of the APK.

      Otherwise, your app needs to be able to handle the provider’s absence.

    </p>

    <p>

      The reason apps use this provider is to take advantage of its

      <code>SecureRandom</code> implementation. If your app was relying on <code>setSeed()</code> to

      derive keys from strings, you must either switch to using <code>SecretKeySpec</code>

      to load raw key bytes directly, or use a real key derivation function

      (KDF).

    </p>

  </li>

</ul>
