title: Where does android.max_aspect meta make difference?
body: <p>A recent <a href="https://android-developers.googleblog.com/2017/03/update-your-app-to-take-advantage-of.html" rel="noreferrer">blog</a> explains that we must use </p>
  
  <pre><code>&lt;meta-data android:name="android.max_aspect" android:value="2.1" /&gt;
  </code></pre>
  
  <p>in <code>&lt;application&gt;</code> element of <strong>AndroidManifest.xml</strong> for optimal display on super widescreen devices, e.g. Samsung Galaxy S8.</p>
  
  <p>To test this, I installed my app (no max_aspect, no resizeableActivity flags; <code>targetSdkVersion=22</code>, <code>compileSdkVersion=24</code>) on an Android 7.1.1. emulator with custom 2960x1440 resolution. All activities, including immersive, fill the screen with no margins as shown in the blog post.</p>
  
  <p>I added explicit</p>
  
  <pre><code>&lt;meta-data android:name="android.max_aspect" android:value="1.5" /&gt;
  </code></pre>
  
  <p>and this also had no effect on the emulator.</p>
  
  <p>So, the question: is this meta flag only checked on the real devices, or there is some configuration that I missed for my emulator?</p>
  
  <p><strong>Update:</strong> I tried to reach <em>Neto Marin</em>, the author of the cited blog post. I found a proud <a href="https://twitter.com/netomarin/status/847163429043494913" rel="noreferrer">tweet</a> <a href="https://twitter.com/netomarin/status/847163429043494913" rel="noreferrer"><img src="https://i.stack.imgur.com/6ltG1.png" alt="]"></a> about his contribution to the global Android Dev community, but could not get an answer from him.</p>
