Shake

<br>If you try to build your Android app with Shake SDK and a <a href="https://github.com/Guardsquare/proguard" rel="nofollow noopener noreferrer" target="_blank">ProGuard</a> version older than 6.0, you'll get an error similar to this one: 

<code>Unknown option '-if' in line 43 of file '\proguard.txt'</code>

To resolve it, update your app's ProGuard version to 6.0 or newer.
