javascript - Accessing user external sd card with cordova -


i'm working on little android application based on cordova , cordova-file plugin. i'm trying access user's files list of them (musics, pictures, media gallery).

i managed access content located on internal sd card, can't figure out clean way access removable/additionnal sd card.

the different paths using cordova.file : 

{   applicationdirectory: "file:///android_asset/"   applicationstoragedirectory: "file:///data/data/com.lbt.www/"   cachedirectory: "file:///data/data/com.lbt.www/cache/"   datadirectory: "file:///data/data/com.lbt.www/files/"   documentsdirectory: null   externalapplicationstoragedirectory: "file:///storage/emulated/0/android/data/com.lbt.www/"   externalcachedirectory: "file:///storage/emulated/0/android/data/com.lbt.www/cache/"   externaldatadirectory: "file:///storage/emulated/0/android/data/com.lbt.www/files/"   externalrootdirectory: "file:///storage/emulated/0/"   shareddirectory: null   synceddatadirectory: null   tempdirectory: null }

but none of allows access additionnal sd card content.

by looking @ folder tree of phone, found out additionnal sd card's content can found in 'file:///storage/extsdcard' or 'file:///mnt/extsdcard'.

knowing managed access it, don't think code adaptative. because i'm using static variable root path 'file:///'.

var app = {   // vars   folders: 0, // number of folder found during scan   scannedfolders: 0, // number of folder scanned   directories: [], // directories scan   // launch app when device ready   init: function(){     document.addeventlistener('deviceready', this.ready, false);   },   // launch directories listing   ready: function(){     var _this = app;     _this.listdirectories();   },   // list directories in we'll files want   listdirectories: function(){     var directory;      // loop through cordova.file directories     for(directory in cordova.file){       var current = cordova.file[directory];       if(current == null || typeof current == 'undefined')         continue;        current = this.stripdirectory(current);       if(this.directories.indexof(current) != -1)         continue;        this.directories.push(current);     }     this.initscan();   },   // launch scan each principal directories   initscan: function(){     var _this = this;     var = 0;     var nbdirectories = this.directories.length;     for(i; < nbdirectories; i++){       var directory = this.directories[i];       window.resolvelocalfilesystemurl(directory, function(dir, callback){         _this.folders++;         _this.scandirectory(dir);       });     }   },   // scan given directory files or other directories   scandirectory: function(directory){     var _this = this;     // initiate reader     var reader = directory.createreader();     // list entries in directory     reader.readentries(function(entries){       var = 0;       var nbentries = entries.length;       // loop through each entries in directory       for(i; < nbentries; i++){         var entry = entries[i];         // if entry directory, scan directory         if(entry.isdirectory){           _this.folders++;           _this.scandirectory(entry);         }         // if entry file, check type         else{           // stuffs           if(entry.fullpath.indexof('\.mp3') != -1)             console.log(entry.fullpath);         }       }       // directory scanned !       _this.scannedfolders++;       // check if folders have been scanned       if(_this.scannedfolders == _this.folders){         console.log('scan finished');       }     });   },   // strip directory 1 folder after root   stripdirectory: function(directory){     directory = directory.split('file:///')[1].split('/')[0];     return 'file:///' + directory + '/';   }, };  // initialize app app.init();

does has better , more modulable approach achieve ?
