title: Cocos2d-X Loading OBB / Expansion Files
body: <p>My Cocos2d-X game is larger than 50 Mo so as I read on the Android documentation I have to use expansion files.
  I followed this subject: <a href="https://stackoverflow.com/questions/18573096/android-obb-zip-loading-cocos2dx">Android OBB/ZIP loading (cocos2dx)</a>
  So I modified Cocos2dxHelper.java and placed my OBB file (a renamed Zip file) on my device's sdcard: /Android/obb/com.project.id/com.project.id.obb
  Unfortunately my OBB file is not loaded.
  I added theses permissions:</p>
  
  <pre><code>&lt;uses-permission android:name="android.permission.INTERNET"/&gt;
  &lt;uses-permission android:name="android.permission.GET_ACCOUNTS"/&gt;
  &lt;uses-permission android:name="com.android.vending.CHECK_LICENSE" /&gt;
  &lt;uses-permission android:name="android.permission.WAKE_LOCK" /&gt;
  &lt;uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /&gt;
  &lt;uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/&gt;
  &lt;uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /&gt;
  </code></pre>
  
  <p>Where is my mistake?
  Did you succeeded with loading assets from an OBB file?
  Is there something else to do?</p>
  
  <p>Thanks in advance.</p>
  
  <p><strong>EDIT:</strong>
  Here is the fullpath of my OBB File: /sdcard/emulated/0/com.emedion.games.bardadum/main.1.com.emedion.games.bardadum.obb
  I read that "/sdcard/emulated/0/" is the correct external storage path since Android 4.2.</p>
  
  <p>I'm testing it on a Nexus 4 with Android 4.4.2.</p>
