title: Android: force gradle to include only one version of a library
body: <p>I use <code>'com.android.support:support-v4:23.3.0'</code> in my <code>build.gradle</code> but when explore external libraries I see two version of support-v4 library (23.3.0 &amp; 24.0.0). How can I find which dependency use support-v4:24.0.0 library?  How can I force gradle to only add version 23.3.0?</p>

  <p>I use <code>exclude group: 'com.android.support', module:'support-v4'</code> to avoid others adding support library but no change happened.</p>
