title: Bluetooth LE still required when set "requried=false"
body: <p>I have set my manifest to use bluetooth low energy feature and I want it to be optional, but when I try to update app in Google Play Store, it says I still require BTLE feature and it cuts my device range.</p>
  
  <p>I've added <code>android:required="false"</code> param but it still doesnt work.</p>
  
  <pre><code>&lt;uses-permission android:name="android.permission.BLUETOOTH"/&gt;
  &lt;uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/&gt;
  
  &lt;uses-feature
          android:name="android.hardware.bluetooth"
          android:required="false"/&gt;
  
  &lt;uses-feature
          android:name="android.hardware.bluetooth_le"
          android:required="false"/&gt;
  </code></pre>
  
  <p>My aapt dump badge:</p>
  
  <pre><code>uses-feature-not-required: name='android.hardware.bluetooth'
  uses-feature: name='android.hardware.bluetooth_le'
  uses-feature: name='android.hardware.camera'
  uses-feature-not-required: name='android.hardware.camera.autofocus'
  uses-feature-not-required: name='android.hardware.camera.flash'
  uses-feature-not-required: name='android.hardware.nfc'
  uses-feature: name='android.hardware.screen.landscape'
  uses-feature-not-required: name='android.hardware.touchscreen'
  uses-feature-not-required: name='android.hardware.wifi'
  uses-feature: name='android.hardware.screen.portrait'
  </code></pre>
  
  <p>On normal bluetooth feature it works, but on BTLE it doesn't.
  I'm using Estimote SDK.</p>
