I'm trying to open a PDF file in my app which I'm building with Ionic. I understand that I can do that using the inAppBrowser.
I first get the PDF from an api endpoint, after which I write it to the filesystem. Once it is written to the file system, I want to open it using the inAppBrowser. The code I have now is as follows:
Controller:
var exampleApp = angular.module('starter', ['ionic'])
.run(function($ionicPlatform) {
$ionicPlatform.ready(function() {
if(window.cordova && window.cordova.plugins.Keyboard) {
cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
}
if(window.StatusBar) {
StatusBar.styleDefault();
}
});
})
exampleApp.controller("FileController", function($scope, $ionicLoading) {
$scope.download = function() {
$ionicLoading.show({
template: 'Loading...'
});
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function(fs) {
fs.root.getDirectory(
"ExampleProject",
{
create: true
},
function(dirEntry) {
dirEntry.getFile(
"khatima.pdf",
{
create: true,
exclusive: false
},
function gotFileEntry(fe) {
var p = fe.toURL();
fe.remove();
ft = new FileTransfer();
ft.download(
encodeURI("http://www.tafseer.info/phocadownload/copy_of_the_book/khatima.pdf"),
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(
"khatima.pdf",
{
create: false,
exclusive: false
},
function gotFileEntry(fe) {
$ionicLoading.hide();
var ref = fe.toURL();
$scope.pdfFile = cordova.InAppBrowser.open(ref, '_system', 'location=no');
},
function(error) {
$ionicLoading.hide();
console.log("Error getting file");
}
);
}
);
},
function() {
$ionicLoading.hide();
console.log("Error requesting filesystem");
});
}
