title: Nougat get LOCKED_BOOT_COMPLETED action
body: <p>As I read in documentation</p>
  
  <p><a href="https://developer.android.com/training/articles/direct-boot" rel="nofollow noreferrer">Direct Boot </a>
  in Android N to receive action that boot was completed when device is locked we should use <code>android:directBootAware</code> and <code>android:encryptionAware</code> attributes in Manifest. Like this:</p>
  
  <pre><code>&lt;receiver
      android:name=".receivers.BootCompletedReceiver"
      android:directBootAware="true"
      android:encryptionAware="true"
      android:exported="false"&gt;
      &lt;intent-filter&gt;
          &lt;action android:name="android.intent.action.LOCKED_BOOT_COMPLETED" /&gt;
      &lt;/intent-filter&gt;
  &lt;/receiver&gt;
  </code></pre>
  
  <p>Unfortunately <code>android:encryptionAware</code> is marked as Unknown attribute.</p>
