In my app I have a problem.
I am able to save image in gallery in using the code below. But when I build apk and install it on my phone, I can't save images on the phone. Why is it so?
//---------------- save.js file ----------------
//First step check parameters mismatch and checking network connection if available call download function
function DownloadFile(URL, Folder_Name, File_Name) {
//Parameters mismatch check
if (URL == null && Folder_Name == null && File_Name == null) {
return;
}
else {
//checking Internet connection availablity
var networkState = navigator.connection.type;
if (networkState == Connection.NONE) {
return;
} else {
download(URL, Folder_Name, File_Name); //If available download function call
}
}
}
function download(URL, Folder_Name, File_Name) {
//step to request a file system
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, fileSystemSuccess, fileSystemFail);
function fileSystemSuccess(fileSystem) {
var download_link = encodeURI(URL);
ext = download_link.substr(download_link.lastIndexOf('.') + 1); //Get extension of URL
var directoryEntry = fileSystem.root; // to get root path of directory
directoryEntry.getDirectory(Folder_Name, { create: true, exclusive: false }, onDirectorySuccess, onDirectoryFail); // creating folder in sdcard
var rootdir = fileSystem.root;
// var fp = rootdir.fullPath; // Returns Fulpath of local directory
var fp = rootdir.toURL();
// fp = fp + "/" + Folder_Name + "/" + File_Name + "." + ext; // fullpath and name of the file which we want to give
fp = "file:///mnt/sdcard/download/" + File_Name + "." + "png"; // fullpath and name of the file which we want to give
// download function call
filetransfer(download_link, fp);
}
function onDirectorySuccess(parent) {
// Directory created successfuly
}
function onDirectoryFail(error) {
//Error while creating directory
//alert("Unable to create new directory: " + error.code);
}
function fileSystemFail(evt) {
//Unable to access file system
alert(evt.target.error.code);
}
}
function filetransfer(download_link, fp) {
var fileTransfer = new FileTransfer();
// File download function with URL and local path
fileTransfer.download(download_link, fp,
function (entry) {
alert("is done" + entry.fullPath);
},
function (error) {
//Download abort errors or download failed errors
alert("download error source " + error.source);
//alert("download error target " + error.target);
//alert("upload error code" + error.code);
}
);
