That is because i would like to have one factory to generate and open pdf files and many controllers each passing his own url and filenames, to keep the controllers thin.
This is the factory from nic raboy tutorial https://blog.nraboy.com/2014/09/manage-files-in-android-and-ios-using-ionicframework/ that uses file-transfer and inappbrowser cordova plugins :
.factory('pdf-service', function($scope, $ionicLoading){
if( window.cordova && window.cordova.InAppBrowser ){
window.open = window.cordova.InAppBrowser.open;
console.log("InAppBrowser available");
} else {
console.log("InAppBrowser not available");
}
$scope.download = function() {
$ionicLoading.show({
template: 'Loading...'
});
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function(fs) {
fs.root.getDirectory("ExampleProject",{create: true},
function(dirEntry) {
dirEntry.getFile(
"pdf-number-1.pdf",
{
create: true,
exclusive: false
},
function gotFileEntry(fe) {
var p = fe.toURL();
fe.remove();
ft = new FileTransfer();
ft.download(
encodeURI("http://www.someservice.com"),
p,
function(entry) {
$ionicLoading.hide();
$scope.imgFile = entry.toURL();
},
function(error) {
$ionicLoading.hide();
alert("Download Error Source -> " + error.source);
},
false,
null
);
},
function() {
$ionicLoading.hide();
console.log("Get file failed");
}
);
}
);
},
function() {
$ionicLoading.hide();
console.log("Request for filesystem failed");
});
}
$scope.load = function() {
$ionicLoading.show({
template: 'Loading...'
});
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function(fs) {
fs.root.getDirectory(
"ExampleProject",
{
create: false
},
function(dirEntry) {
dirEntry.getFile(
"pdf-number-1.pdf",
{
create: false,
exclusive: false
},
function gotFileEntry(fe) {
$ionicLoading.hide();
$scope.imgFile = fe.toURL();
alert(fe.toURL());
window.open(fe.toURL(), '_system', 'location=no,toolbar=yes,closebuttoncaption=Close PDF,enableViewportScale=yes');
},
function(error) {
$ionicLoading.hide();
console.log("Error getting file");
}
);
}
);
},
function() {
$ionicLoading.hide();
console.log("Error requesting filesystem");
});
}
});
