title: App crashes when using function of this package REACT NATIVE
body: <p>Im building a music player and I need to get all music files, to do that I'm using this package: <a href="https://github.com/cinder92/react-native-get-music-files" rel="nofollow noreferrer">get-music-files</a></p>
  <p>But there's a problem, the app crashes im my device when I run one of its method, this one:</p>
  <pre><code>MusicFiles.getAll({
          id : true,
          blured : false,
          artist : true,
          duration : true, //default : true
          cover : true, //default : true,
          title : true,
          cover : true,
          batchNumber : 5, //get 5 songs per batch
          minimumSongDuration : 10000, //in miliseconds,
          fields : ['title','artwork','duration','artist','genre','lyrics','albumTitle']
      });
  </code></pre>
  <p>And the expected output is this:</p>
  <pre><code>    [
     {
      id : 1,
      title : &quot;La danza del fuego&quot;,
      author : &quot;Mago de Oz&quot;,
      album : &quot;Finisterra&quot;,
      genre : &quot;Folk&quot;,
      duration : 132132312321, // miliseconds
      cover : &quot;file:///sdcard/0/123.png&quot;,
      blur : &quot;file:///sdcard/0/123-blur.png&quot;, //Will come null if createBLur is set to false
      path : &quot;/sdcard/0/la-danza-del-fuego.mp3&quot;
    }
  ]
  </code></pre>
  <p>In the emulator it doesn't crash, but gives me an error <code>Something get wrong with musicCursor</code> while in my device in debug mode when I run the method the app crashes and close</p>
  <p>If I don't enable these permissions in the emulator:</p>
  <pre><code>&lt;uses-permission android:name=&quot;android.permission.READ_EXTERNAL_STORAGE&quot; /&gt;
  &lt;uses-permission android:name=&quot;android.permission.WRITE_EXTERNAL_STORAGE&quot;/&gt;
  </code></pre>
  <p>The app will crash as in the device, but if they are enable at least it will print the error but in the device with they enable it just crash, i also make sure in <code>AndroidManifest.xml</code> these permissions are in, what could be the problem? Maybe it's because this package is from two years ago?</p>
