title: Android Studio appcompat drawable-hdpi-v4 resources not found
body: <pre><code>Error:java.io.FileNotFoundException: 
  ...\app\build\intermediates\res\merged\debug\drawable-hdpi-v4\abc_scrubber_control_to_pressed_mtrl_005.png
  (The requested operation cannot be performed on a file with a user-mapped section open)
  </code></pre>
  
  <p>It is happenning randomly, one of each two times the project is built.
  And the missed file is not only <code>abc_scrubber_control_to_pressed_mtrl_005.png</code>, but always is a drawable resource used in AppCompat styles.</p>
  
  <pre><code>android {
      compileSdkVersion 24
      buildToolsVersion "24.0.3"
      ...
  }
  dependencies {
      ...
      compile 'com.android.support:appcompat-v7:24.2.1'
  }
  </code></pre>
  
  <p>I have also tried with older SDK versions &amp; older appcompat library version cause a possible bug in new releases, but the error keeps showing up :(</p>
