title: App dies with “Sending signal. SIG: 9” while rotating
body: <p>I'm working on cross-platform Unity application. I tested apps both on Android and iOS about month ago and they rotated properly. But now Android app is not rotating. But iOS app still rotate perfectly.</p>
  
  <p>When I rotate mobile device, I receive next message in <b>Android Monitor</b>:</p>
  
  <pre><code>I/Process: Sending signal. PID: 2658 SIG: 9
  </code></pre>
  
  <p>I tried to override Activity's <code>onConfigurationChanged()</code> like <a href="https://developer.android.com/guide/topics/resources/runtime-changes.html#HandlingTheChange" rel="noreferrer">there</a>, but it doesn't invoke while phone rotating, so it stops earlier.</p>
  
  <p>I tested this behavior both on phone (Doogee X5 Max, API 23) and emulators (API 19, 22 and 23). Result is the same.</p>
  
  <p>What it can be caused? Thanks for response.</p>
  
  <p>Maybe there can be some bugs in recent versions of Android developing environment (I have Android Studio 2.3, Android SDK Tools 25.2.2, Unity 5.5.2f1), but I didn't find any info about similar bugs in Google.</p>
