title: android:maxSDKVersion - couldn't upload apk to alpha
body: <p>I've faced the problem uploading app to Play Store. The old "19" version was available for API versions 10 and above. New "20" version specified maxSDKVersion=22 (not higher Android 5.1).
  An error message, when trying to upload "20", says:</p>
  
  <blockquote>
    <p>"it is forbidden that a device upgrading from API levels in the range
    10-22 to API levels in the range of 23+ should downgrade from version
    20 to version 19, which could happen if...".</p>
  </blockquote>
  
  <p>This situation clearly specified in <a href="http://developer.android.com/intl/ru/guide/topics/manifest/uses-sdk-element.html#max" rel="nofollow">documentation</a>: </p>
  
  <blockquote>
    <p>...future versions of Android (beyond Android 2.0.1) will no longer 
    check or enforce the maxSdkVersion attribute during installation or
    re-validation. Google play will continue to use the attribute as a
    filter, however, presenting users with applications available for
    download.</p>

  <p>Our application not working properly on Android 6, so we should somehow to prevent installs on those devices.</p>
