I'm creating a simple webview app using nativescript-vue where there is nothing else in the app except the webview that loads a website fullscreen.
On iOS it works great, I can log in to the website turn the app off and on and I'm still logged in.
On Android, the cookies are not saved and you have to log in again every time you turn the app off.
Any way I can enable cookies in the webview for Android?
I couldn't make it work with cookies, so I had to switch and use localstorage as a backup for saving tokens instead of cookies.
Here is how my final version looks:
<template>
<Page>
<WebView #loadStarted="onLoadStarted"
#loaded="onWebViewLoaded"
src="https://yoururl.com/"
/>
</Page>
</template>
<script>
import { isAndroid } from "tns-core-modules/platform"
export default {
methods: {
onLoadStarted (webargs) {
if (isAndroid) {
const webView = webargs.object;
webView.android.getSettings().setDomStorageEnabled(true) // This will enable local storage
}
},
onWebViewLoaded(webargs) { // I use this only to disable the default zoom buttons
if (isAndroid) {
const webView = webargs.object;
webView.android.getSettings().setDisplayZoomControls(false)
webView.android.getSettings().setBuiltInZoomControls(false)
}
},
}
};
</script>
Apparently, you should be able to enable cookies doing this (at least for newer SDK users):
webView.on(WebView.loadStartedEvent, (args) => {
webView.android.getSettings().setAcceptThirdPartyCookies(webView, true)
});
But that didn't work as expected as it seemed like sometimes it would save cookies and sometimes it won't or sometimes it would remove cookies (when you log out) and sometimes not.
I hope this info helps someone as it sure seems there is little to none info about this especially if you aren't much familiar with pure Java Android development.
This code should work
const webView = webargs.object;
if (android.os.Build.VERSION.SDK_INT >= 21) {
android.webkit.CookieManager.getInstance().setAcceptThirdPartyCookies(webView.android, true);
}

I have three buttons on my website, that link to Facebook, Twitter & vk.com pages. I want to open native app, if it is installed on user device. Otherwise, I want URL fallback to be opened.
First of all, I tried to use native app schemes directly with deep-link.js plugin. But, when I tried to open native app URL scheme, when native app was not installed, Safari has shown an error, but opened URL fallback page finally. Default Android browser said that he does not know how to handle such URL scheme:
<a class="btn btn-primary" href="https://www.facebook.com/warpcompany" data-app-ios="fb://profile/838619192839881" data-app-android="fb://page/838619192839881">Facebook</a>
Then I tried to use App Links "standard", that that has so much promotion from Facebook. I even tried to use their hosted app links, to make sure I've generated everything right way. It does not work, it always redirect to website fallback. You can easily test it by yourself from https://fb.me/746134728830806
Is it possible to provide deep link on website, that will open native app without errors at least in default os browsers, or fallback silently to URL?
It is still possible, but on newer versions of the Android default browser you have to use intents instead of just trying to open the deep link. For example replace your fb://page/838619192839881 with
intent://page/838619192839881#Intent;scheme=fb;package=com.facebook.katana;end
This will fallback to Google play by default, but you can override the fallback adding a S.browser_fallback_url:
intent://page/838619192839881#Intent;scheme=fb;package=com.facebook.katana;S.browser_fallback_url=http%3A%2F%2Fwww.facebook.com%2F;end
The fallback should be url encoded.
Of course you'll have issues if the user is not on an Android phone or with an old version of the default browser (or strange browser). You can setup a bunch of conditions and replace your HTML with the correct code for each case.
The accepted answer will only work on Chrome v28 and default browsers for Android 5.0. If you want this to work on other browser like Facebook/Twitter webviews, Firefox, UC and older default browsers than 5.0, you'll need to use some code that's a little more complicated.
Add this function to your JS snippet:
var openSesame = function() {
var method = 'iframe';
var fallbackFunction = function() {
if (method == 'iframe') {
window.location = "market://details?id=com.facebook.katana";
}
};
var addIFrame = function() {
var iframe = document.createElement("iframe");
iframe.style.border = "none";
iframe.style.width = "1px";
iframe.style.height = "1px";
iframe.src = "fb://page/838619192839881";
document.body.appendChild(iframe);
};
var loadChromeIntent = function() {
method = 'intent';
document.location = "intent://page/838619192839881#Intent;scheme=fb;package=com.facebook.katana;end";
};
if (navigator.userAgent.match(/Chrome/) && !navigator.userAgent.match("Version/")) {
loadChromeIntent();
}
else if (navigator.userAgent.match(/Firefox/)) {
window.location = "fb://page/838619192839881";
}
else {
addIFrame();
}
setTimeout(fallbackFunction, 750);
};
Then your button will look like this:
Open the App
Or you can use a service like branch.io which does exactly what you're looking for automatically.
Yes it is! Have a look to this training:

Good day! I am developing a simple mobile app using jQuery Mobile with InAppBrowser plugin on IntelXDK. The purpose of the InAppBrowser is to let users view external web pages within the app. On IntelXDK emulator, the browser closes when I click on "Return to App" button and then it returns to the app. However, I encountered a problem on an Android build when I clicked on the "Done" button I received the message:
Webpage not available
The webpage at file:///android_asset/www/[object%20Event] might be temporarily down...
I have used the following so users can click and view external web pages:
Opening links in external device browser with Cordova/jQuery-mobile
I have modified the above to be used on my app:
$(document).on('click', '.link', function (e) {
var elem = $(this);
var url = elem.attr('href');
if (url.indexOf('http://') !== -1) {
e.preventDefault();
document.addEventListener("deviceready", onDeviceReady, false);
onDeviceReady(url);
//return false;
}
});
function onDeviceReady(url) {
var ref = window.open(url, '_blank', 'location=yes');
}
Thank you for your time and help. I really appreciate it.
The reason why it was displaying an error message because the test file was calling another onDeviceReady function. Problem solved!
Is there a way to create a serious HTML/CSS/JS project with multiple HTML, CSS, JS files on JSfiddle.net ?
If yes, how to do it ?
I want to create a basic mobile apps based on HTML/CSS/JS, about a dozen of HTML/CSS/JS files. I would like to develop it all on JSfiddle, my favorite Online JavaScript IDE. But JSfiddle.net while a clean way to test projects stays limited to:
1 html file (personal)
1 CSS file (personal)
1 JS file (personal)
several external resources (CSS, JS libs, data) which request you another webhosting.
The official doc suggesting Github hosting for 1HTML/1JS/1CSS/someDataFiles is not satisfying. I wish all on JSFiddle, and more files in my project.
You can do it inside a jsFiddle but there are few limitations, and you are probably not going to be satisfied with it.
You can test only 1 HTML multiple pages template. But in case of jQuery Mobile framework this will be enough, as you can place numerous jQM pages inside a 1 html file.
For example, this is my jsFiddle template when helping to this group: http://jsfiddle.net/Gajotres/yWTG2/
You cant use normal form submitting. Instead you should use ajax to sumbit form data.
In my other answer you can find solutions for ajax form submitting and how to send parameters during the page transition: jQuery Mobile: Sending data from one page to the another
In case you want to communicate with an remote host:
var ajax = {
sendRequest:function(save_data){
$.ajax({url: 'http://localhost/JSONP_Tutorial/json.php',
data: save_data,
async: true,
beforeSend: function() {
// This callback function will trigger before data is sent
$.mobile.showPageLoadingMsg(true); // This will show ajax spinner
},
complete: function() {
// This callback function will trigger on data sent/received complete
$.mobile.hidePageLoadingMsg(); // This will hide ajax spinner
},
success: function (result) {
if(result == "true") {
$.mobile.changePage( "#index", { transition: "slide"} ); // In case result is true change page to Index
} else {
alert('Login unsuccessful, please try again!'); // In case result is false throw an error
}
// This callback function will trigger on successful action
},
error: function (request,error) {
// This callback function will trigger on unsuccessful action
alert('Network error has occurred please try again!');
}
});
}
}
jsFiddle has a stupid policy where they want to prevent usage of full HTML files. They are trying to enforce this with stupid error warnings in HTML content part. You will need to have something like firebug plugin for Firefox or Chrome to remove this stupidity. Or you can even do it with Grease Monkey plugin.
In case you want to use full HTML template like in this example: http://jsfiddle.net/Gajotres/yWTG2/ you will need to use your javascript code in onDomready state.
Some functionalities are not going to work. Like window.orientationchange event.
I'm using Local Storage to pass values between pages in order to create a scroll to effect (user clicks link and is scrolled to particular part of the page based on ID)
I was previously using cookies but that didn't seem to work on Android, I read that local storage was supported so switched over to that. It works completely fine when in the browser but as soon as its packaged as a native app I lose all functionality? The API states that it should be supported, any ideas?
Here's my code:
Base URL:
var storage = window.localStorage;
$("a.scroll_link").click(function(event) {
event.preventDefault();
var value = $(this).attr("id");
storage.setItem("key",value);
console.log(value);
window.location=$(this).attr("href");
});
Receiving URL:
$(function () {
var value = window.localStorage.getItem("key");
if (value != "" && value != "undefined" && value != null) {
var storage = window.localStorage;
storage.setItem("key",value);
var scroll_type = "";
if ($.browser.webkit) {
scroll_type = "body";
} else {
scroll_type = "html";
}
$(scroll_type)
.stop()
.animate({
//get top-position of target-element and set it as scroll target
scrollTop: ($("#" + value).offset().top - 25)
//scrolldelay: 1.5 seconds
}, {
duration: 1500,
complete: function () {
storage.removeItem("key");
},
});
}
});
The code works fine in the browser just not natively, any ideas?
Thanks,
Use document.addEventListener("deviceready", onDeviceReady, false) instead of $(function(){...}
http://docs.phonegap.com/en/2.5.0/cordova_events_events.md.html#deviceready
1.Glad to know you solve your first problem. As gmh04 say, I think you should replace your init event with 'deviceready' which is triggered when the app start running.
2.
You mean window.localStorage.getItem("key") return null in Receiving URL?
I do not exactly encounter a problem as what you describe. However, you may try to move your code in receiving url to the same page of base url. I have tried for times and be very sure that the localStorage will work in the same page.
I would like add that there's a bug on the 2.6.0 version of cordova.js that make localStorage don't work on Android:
https://issues.apache.org/jira/browse/CB-3063
On the 2.5.0 version it works perfectly, and it is already fix on the 2.7.0 rc.
I am building a phonegap based mobileweb application which is built almost completely with jquerymobile.
In couple of pages, there are links to external sites and the client wants to show a popup asking if the user is willing to leave the app and go to the external site. Client also asked that the application shall exit if the user chooses to follow the link.
Here is my JS:
if (typeof CORP == "undefined" || !CORP) {
var CORP = {};
}
(function() {
CORP.mk = {
var mobile = false;
init: function() {
$("[data-role='page']").on("pagebeforeshow", CORP.mk.setHandlers);
},
onDeviceReady: function () {
CORP.mk.mobile = true;
document.addEventListener("pause", CORP.mk.onPause, false);
},
onPause: function () { // Exit the app if it goes to background
navigator.app.exitApp();
},
setHandlers: function () {
if ( CORP.mk.mobile ) {
$("a[rel='external']").click(function (e) {
e.preventDefault();
CORP.mk.externalLink = $(this).attr("href");
alert(CORP.mk.externalLink);
navigator.notification.confirm("You are about to close this mobile app and open your web browser.",
CORP.mk.popupConfirm,
"Close This App?");
});
}
}
};
})():
$(document).bind("pageinit", CORP.mk.init);
document.addEventListener("deviceready", CORP.mk.onDeviceReady, false);
Here is my markup:
<a rel='external' data-ajax='false' href='http://www.google.com'>googly</a>
Problem: I tested this code ignoring CORP.mk.mobile on chrome desktop browser and it works fine. However $(this).attr("href"); always returns '#' for the href in Android or IOS and I cannot launch external application with phonegap. I want to be able to get the actual link and launch external app. I tried many combinations and couldn't find a solution. Appreciate any insights.
Finally found the issue. This is happening due to e.preventDefault(); which is replacing the link. I am surprised that this doesn't happen in desktop browsers..
So, instead of
e.preventDefault();
CORP.mk.externalLink = $(this).attr("href");
I need to do
CORP.mk.externalLink = $(this).attr("href");
e.preventDefault();
