I want to access into a Camera directory in an Android device in this path /storage/emulated/0/DCMI/Camera. I followed this tutorial http://nightlycoding.com/index.php/2015/06/phonegapcordova-read-images-from-gallery-folder-tip/ that uses Cordova File Plugin, https://github.com/apache/cordova-plugin-file. The problem is, if I ran the app on an Android 4.3, I can access into these files, but when I tested the app on an Android Lollipop device, the files/directories inside that directory are empty.
I let you the code here

var app = {

initialize: function() {
this.bindEvents();
},
// Bind Event Listeners

// Bind any events that are required on startup. Common events are:
// 'load', 'deviceready', 'offline', and 'online'.
bindEvents: function() {
document.addEventListener('deviceready', this.onDeviceReady, false);
},
// deviceready Event Handler

// The scope of 'this' is the event. In order to call the 'receivedEvent'

onDeviceReady: function() {
window.resolveLocalFileSystemURL(cordova.file.externalRootDirectory, onFileSystemSuccess, function(){alert("fail");});
},
};
//app.mediaFiles = [];
function onFileSystemSuccess(fileSystem) {
window.console.log(cordova.file.externalRootDirectory);
window.console.log(JSON.stringify(fileSystem));
var directoryReader = fileSystem.createReader();
alert(JSON.stringify(directoryReader)); //1
directoryReader.readEntries(function (entries) {
var i;
alert(JSON.stringify(entries)); //2
for (i = 0; i < entries.length; i++) {
if (entries[i].name === "DCIM") {
var dcimReader = entries[i].createReader();
dcimReader.readEntries(onGetDCIM, fail);
break; // remove this to traverse through all the folders and files
}
}
}, function () {
window.console.log("fail");
});
}
function onGetDCIM(entries) {
var i;
for (i = 0; i < entries.length; i++) {
if (entries[i].name === "Camera") {
var mediaReader = entries[i].createReader();
mediaReader.readEntries(onGetFileNames, fail);
break; // remove this to traverse through all the folders and files
}
//This will log all files and directories inside 100MEDIA
alert(" >>>>>>> " + entries[i].name);
}
}
function onGetFileNames(entries) {
var i;
var flag=true;
console.log("files");
for (i = 0; i < entries.length; i++) {
if (/\.(jpe?g|png|gif|bmp)$/i.test(entries[i].name)) {
if (flag){
alert(entries[i].nativeURL);
mostrarImagen(entries[i].nativeURL);
flag=false;
}
//app.mediaFiles.push(entries[i]);
//alert(JSON.stringify(entries[i]));
}
//This will log all image files found
}
}
function mostrarImagen(ImagePath){
alert("mostrar la foto " + ImagePath);
var imagen = new Image();
imagen.src = ImagePath;
document.getElementsByName("foto").src= imagen.src;
}
app.initialize();
the first alert on "onFileSystemSuccess" function shows {"localURL":"cdvfile://localhost/sdcard/","hasReadEntries":false}. In android 4.3 the second alert shows the list of the subdirectories on that path but with Android 5 that list was empty.
Some solution? how could I access to an external file on an Android Lollipop device?
