Best approach to Notification Sounds on Web Apps - java

I have a Delivery System that I made with Laravel + Vue.Js and all is working fine, but I'm facing some problems with Notification Sounds.
When the client makes an order on his cellphone or pc, I need to show a Notification sound alert with a custom sound to admin from the Restaurant.
But when I'm working with Chrome or Mozilla, sometimes my Notification doesn't show up and the custom sound only plays if the admin stays on the web page but not in another tab or minimized.
I want to make this process 100% with the sound and the Notification always showing.
When I see another competitor's software I see that they have a small java desktop application only to do that. I can do some similar with Electron?
But I don't have any idea where to start making some like this or the name is called.
Here is my code for notification on my Web Application, I'm using FCM:
const messaging = firebase.messaging();
navigator.serviceWorker.register("{{url('firebase/sw-js')}}")
.then((registration) => {
messaging.useServiceWorker(registration);
messaging.requestPermission()
.then(function() {
console.log('Notification permission granted.');
getRegToken();
})
.catch(function(err) {
console.log('Unable to get permission to notify.', err);
});
var audio = new Audio('urltosound.mp3');
messaging.onMessage((payload) => {
console.log("Message received. ", payload);
notificationTitle = payload.data.title;
notificationOptions = {
body: payload.data.body,
icon: payload.data.icon,
image: payload.data.image,
requireInteraction: true,
};
var notification = new Notification(notificationTitle, notificationOptions);
notification.onshow = function() {
audio.play();
audio.loop = true;
};
notification.onclose = function() {
audio.pause();
audio.currentTime = 0;
};
notification.onclick = function() {
audio.pause();
audio.currentTime = 0;
// window.location.href = '/administrativo/orders/' + payload.data.orderid;
window.open('/administrativo/orders/' + payload.data.orderid, '_blank');
};
notification.addEventListener('close', () => {
audio.pause();
audio.currentTime = 0;
});
});
});
It is working but when we are playing with Notification and Custom Sound on a Browser I'm not very confident that always will play and show and this can't happen.

How to make a URL in a balloon notification clickable?

I'm creating a simple IntelliJ Plugin that allows for creating new Pastebin pastes straight from the IDE.
When a paste has been successfully posted to Pastebin, I'd like to display a balloon notification.
Currently the notification is displayed as follows:
final Response<String> postResult = Constants.PASTEBIN.post(paste);
NotificationGroup balloonNotifications = new NotificationGroup("Notification group", NotificationDisplayType.BALLOON, true);
if (postResult.hasError()) {
//Display error notification
} else {
//Display success notification
Notification success = balloonNotifications.createNotification("Successful Paste", "Paste successfully posted!", NotificationType.INFORMATION, null);
Notifications.Bus.notify(success, project);
}
Now, this balloon notification contains the URL to the newly created paste, but unfortunately clicking it does not open the link in a browser. How can that be achieved?
The balloon notification with the URL that should become clickable:
There is NotificationListener which opens urls in notifications: com.intellij.notification.UrlOpeningListener
So you can write:
Notification success = balloonNotifications.createNotification(
"<html>Successful Paste", "Paste successfully posted!</html>",
NotificationType.INFORMATION, new NotificationListener.UrlOpeningListener(true));
After some searching I found the answer myself. It wasn't too difficult actually.
If I instantiate the notification as follows, the link is clickable as was required.
Notification success = balloonNotifications.createNotification("<html>Successful Paste", "Paste successfully posted!</html>", NotificationType.INFORMATION, (notification, hyperlinkEvent) -> {
if (hyperlinkEvent.getEventType() == HyperlinkEvent.EventType.ACTIVATED) {
BrowserUtil.browse(hyperlinkEvent.getURL());
}
});
Note: It is also rather useful that the link in the event log is also clickable now.

Cordova Jquery Mobile Local Notification onclick change page

I'm sorry for the long post, but I think this is the only way to explain whats happening... I'm looking for help after a lot of research with no answers... A big problem I think...
So this web app schedule a local notification based on a time picker that the users interact with..
I'm using cordova and jquery mobile multi-page system... It changes from page to page by div IDs, the navigation looks like this: index.html, index.html#page2, index.html#page3..
The local notification is a java plugin for cordova Katzer Local Plugin.
The plugin only works inside the onDeviceReady function and the jquery mobile does not, like this...
document.addEventListener('deviceready', onDeviceReady, false);
/* JQUERY MOBILE HERE */
$(document).on("pagecreate", "#home", function(event) {
$("a#btnpage2").click(function (e) {
e.stopImmediatePropagation();
e.preventDefault();
$( "#page2" ).pagecontainer( "change"); // change to #page2
});
});
$(document).on("pagecreate", "#page2", function(event) {
console.log("#page2 created");
});
function onDeviceReady(){
/* NOTIFICATION PLUGIN HERE */
//create notification
var msg = "notification message";
window.plugin.notification.local.add({
id: 'notif',
date: dateobject,
message: msg,
json: JSON.stringify({ test: msg }),
title: 'Title',
autoCancel: true,
ongoing: false
});
//onclick event notification
window.plugin.notification.local.onclick = function (notif, state, json) {
var msg = JSON.parse(json).test;
$( "#notificationPage" ).pagecontainer( "change", { text: msg} ); //pass data and change to #page2
}
//ontrigger notification
window.plugin.notification.local.ontrigger = function (notif, state, json) {
var msg = JSON.parse(json).test;
}
}
When the notification is fired, and when I click it, it should change the page to #notificationPage.
The problem is that the command inside onclick, does not work even when I click the notification with the app running, it throws this error:
Uncaugh Error: cannot call methods on pagecontainer prior to initialization; attempted to call method 'change'.
However the following command DOES change the page, found it on google: $.mobile.changePage( "#notificationPage" ). But only if the app is running and not interrupted. I think that if its in background or closed even if its not interrupted, it doesn't change the page... it opens the activity defined by the plugin. When I say in background or closed and not interrupted i mean that app was closed by the main button and not the back button that completely closes the app..
I guess this is the classes that handle the notification:
/* Receiver.class notification plugin */
Intent intent = new Intent(context, ReceiverActivity.class)
.putExtra(OPTIONS, options.getJSONObject().toString())
.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
int requestCode = new Random().nextInt();
PendingIntent contentIntent = PendingIntent.getActivity(context, requestCode, intent, PendingIntent.FLAG_CANCEL_CURRENT);
return notification.setContentIntent(contentIntent);
/* ReceiverActivity.class notification plugin */
Context context = getApplicationContext();
String packageName = context.getPackageName();
Intent launchIntent = context.getPackageManager().getLaunchIntentForPackage(packageName);
launchIntent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT | Intent.FLAG_ACTIVITY_SINGLE_TOP);
launchIntent.putExtra("MSG", msgJson); // here I pass the json message to the new intent, thats gonna open when clicking the notification
context.startActivity(launchIntent);
So basically, I want to click the notification, and open a specific page, so I can get the json value on click and pass to that page and then display it to a div element... It seems I can't use the notification plugin commands outside the onDeviceReady, and neither jquery mobile commands inside the onDeviceReady.... Beside that I have to deal with the problem that is to do the same thing if the app is closed and interrupted...
At the java side, I could create another activity along with the main cordova app activity, and create a layout in xml, and add a textview... On the .java file of this new activity I think I could set the setContentView to this xml layout, and set the text of the textView to the json object value I want... this json value is the same as the message of the notification... I pretty sure, like 95% convinced this would work, not tested yet, but the thing is, its hard to maintenance.
What I tried is create this new activity, exactly like the main activity of cordova, but the loadUrl, I set to the page I want to go, not to LaunchUrl, which loads the address from config.xml of cordova, and passed the json value that I added as extra on the intent creation as a url param so on the jquery mobile side I could take the document.URL and the parameter... like this, first I edited the ReceiverActivity.class from notification plugin:
/* ReceiverActivity.class notification plugin */
Context context = getApplicationContext();
//String packageName = context.getPackageName();
Intent launchIntent = new Intent(context, NotificationActivity.class);
launchIntent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT | Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
launchIntent.putExtra("MSG", msgJson);
context.startActivity(launchIntent);
/* NotificationActivity.class cordova app second activity */
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
String msg;
Intent intent = getIntent();
Bundle extras = intent.getExtras();
msg = extras.getString("MSG");
String utf_encoded = null;
try {
utf_encoded = URLEncoder.encode(msg,"UTF-8");
} catch (UnsupportedEncodingException e) {}
String url = "file:///android_asset/www/index.html#notificationPage?parameter="+utf_encoded;
super.loadUrl(url);
}
And on the javascript side, I could retrive that parameter in the url:
document.addEventListener('deviceready', onDeviceReady, false);
$( document ).on( "pagebeforechange" , function ( event, data ) {
if ( data.toPage[0].id == "notificationPage" ) {
var url = document.URL;
var urlParams = decodeURIComponent(url);
var onlyParams = urlParams.split('=')[1];
var newchar = " ";
var paramValue = onlyParams.split('+').join(newchar);
$('#notificationPage #showMessage').empty();
$('#notificationPage #showMessage').append("<p>Message: " + paramValue + "</p>");
}
});
function onDeviceReady(){
/* ondeviceready */
}
This actually worked, but it has some bugs... Sometimes the page loads, sometimes the page doesn't load, the page sometimes turned to a black screen... It works specially if the app is closed and interrupted, but if its open, most of the times it goes to a black screen... and if I click the back button on the device, it "navigates back", but it actually goes to the page that should be activated and showing the message... its like the page is behind this black screen sometimes and it won't come out to front unless I use back button..
I'm out of options... tried almost everything with no concrete and stable solution.. Flags, javascript, java, redirect url at javascript, at java, nothing seems to work...
Well I'm not a developer. I'm a designer, putting all my efforts to finish this... but god, its hard.... Theoretically a easy solution would be leaving everything at defaults, and when the plugin "launch" the app or the intent, or whatever by clicking the notification, just run a javascript with the command from jquery mobile that change pages... That would be amazing! hahah
I really need help..
Thanks to everyone that is reading this... To everyone that will try to help me...
Thank you all
Use this method:
cordova.plugins.notification.local.on("click", function (notification) {
alert(notification.text);
}, scope);
Here is the updated doc.

HTML5 Audio Mute in Android webview

I am using HTML5 audio player inside an android webview. I want to mute the audio and I am using the code like this
this.mute = function()
{
console.debug("Muted");
if(_audioHtml.muted == undefined) {
alert("Doesn't exist");
}
else {
if(_audioHtml.muted === true) {
alert("Muted");
}
else if (_audioHtml.muted === false) {
alert("Non Muted");
}
else {
alert("None of them");
}
}
_audioHtml.muted = true;
};
After each call I can see that the value of muted changes. But its not generating any effect on the device. It always generate the sound in set volume. How can I do this in android. I am using Android 4.0.4.
Thanks.
Assuming an audio tag like <audio id="player" src="something.mp3" />, you should be toggling the muted property of the tag itself using Javascript... something like
$('#player').muted = true;
It works if you set the audio this way: (the html5 tag will be muted)
In your JAVA activity:
wv.loadUrl("file:///android_asset/index.html");
wv.addJavascriptInterface(this, "jInterface");
in your html file:
to mute:
<script>
jInterface.mute();
</script>
now back to your java activity:
public void mute()
{
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 0, 0);
}
I haven't found a solution for my MotoX 4.2 device yet, but this tends to work in most cases, basically you have pause the video once it starts playing
The caveat here is that my Samsung 4.3 device is firing "playing" way too early, it should fire when the video actually starts playing, but it fires when the video starts loading
if (sdkVersion < 4.4) {
player.addEventListener("timeupdate", pauseIfPlaying); // check player.currentTime > 0
} else {
player.addEventListener("playing", function () {
player.muted = true;
});
}

Html/Javascript debugging in JavaFX WebView

Are there any ways to debug javascript and html that is executed within a Javafx WebView? Something similar to Firebug or Chrome's developer console?
I have an application that renders fine in Firefox and Chrome, but does not render correctly inside a WebView. It really could be any number of things, but without some debugging tools I don't know how to track down the root cause.
Thanks.
Here is some Java code to make use of Firebug Lite in a JavaFX WebView without modifying the html of the target page.
webView.getEngine().executeScript("if (!document.getElementById('FirebugLite')){E = document['createElement' + 'NS'] && document.documentElement.namespaceURI;E = E ? document['createElement' + 'NS'](E, 'script') : document['createElement']('script');E['setAttribute']('id', 'FirebugLite');E['setAttribute']('src', 'https://getfirebug.com/' + 'firebug-lite.js' + '#startOpened');E['setAttribute']('FirebugLite', '4');(document['getElementsByTagName']('head')[0] || document['getElementsByTagName']('body')[0]).appendChild(E);E = new Image;E['setAttribute']('src', 'https://getfirebug.com/' + '#startOpened');}");
You can trigger the code using a JavaFX Button or any other mechanism you wish.
I am debugging JavaFx WebView with chrome DevTools and safari Web Inspector.
I created minimal project to help people debug with DevTools. Get it on GitHub. You can find there:
runnable javaFXWebKitDebugger.jar
source code of created javaFXWebKitDebugger.jar
The sample opens WebView and enables WebSocket Servlet. When you run javaFXWebKitDebugger.jar open Chrome browser and load: dev tools url
You can try Firebug Lite, which can be incorporated into any web-browser. See http://www.makeuseof.com/tag/install-firebug-for-browsers-other-than-firefox/
Maybe a bit late to answer, but I think this way is quite simple.
add javascript listener in java
Java :
webengine.getLoadWorker().stateProperty().addListener(new ChangeListener<State>() {
#Override
public void changed(ObservableValue<? extends State> observable,
State oldValue, State newValue) {
JSObject jsobj = (JSObject) webengine.executeScript("window");
jsobj.setMember("java", new JSListener());
}
});
Then create the JS listener class in java.
JSListener java:
public class JSListener {
public void log(String text){
System.out.println(text);
}
}
add javascript in html file
Javascript:
var javaReady = function(callback){
if(typeof callback =='function'){
if(typeof java !='undefined'){
callback();
} else {
var javaTimeout = 0;
var readycall = setInterval(function(){
javaTimeout++;
if(typeof java !='undefined' || javaTimeout > 1000){
try{
callback();
} catch(s){};
clearInterval(readycall);
}
},1);
}
}
};
var errorlistener = function(msg, url, line){
javaReady(function(){
java.log(msg +", url: "+url+ ", line:" + line);
});
};
//overide onerror
var onerror = errorlistener;
If you want to load html from the outside, you can not to change it, you can use code like this.
var testsss = window.open("http://testError.com");
testsss.onerror = errorlistener;
but first you need to add setCreatePopupHandler in java, to make it you can see here: webview not opening the popup window in javafx

Prompt Android App User to Update App if current version <> market version

Lets say my Android App version 0.1 is installed currently on the User's phone. Everytime they launch my App I want to check if there is a different version available in the Android Market let's say this version is 0.2. If there is a mismatch between these two version I want to show a dialog box prompting the user to Upgrade the App.
I totally understand there exists a notification procedure from Android Market itself to the users but as far as my Analytics data is concerned it is not very effective in reminding users to upgrade to the new version of the App.
Any insight would be very helpful. Thanks StackOverflowers, you guys rock!
As of 2019 the best way for updating your app is to use In-app updates provided by Play Core library (1.5.0+). It works for Lollipop and newer, but let's be fair, Kit-Kat is less than 7% as of today and soon will be gone forever. You can safely run this code on Kit-Kat without version checks, it won't crash.
Official documentation: https://developer.android.com/guide/app-bundle/in-app-updates
There are two types of In-app updates: Flexible and Immediate
Flexible will ask you nicely in a dialog window:
whereas Immediate will require you to update the app in order to continue using it with full-screen message (this page can be dismissed):
Important: for now, you can't choose which type of update to roll out in your App Release section on Developer Play Console. But apparently, they will give us that option soon.
From what I've tested, currently, we're getting both types available in onSuccessListener.
So let's implement both types in our code.
In module build.gradle add the following dependency:
dependencies {
implementation 'com.google.android.play:core:1.6.1'//for new version updater
}
In MainActivity.class:
private static final int REQ_CODE_VERSION_UPDATE = 530;
private AppUpdateManager appUpdateManager;
private InstallStateUpdatedListener installStateUpdatedListener;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

if (resultCode != RESULT_OK) { //RESULT_OK / RESULT_CANCELED / RESULT_IN_APP_UPDATE_FAILED
L.d("Update flow failed! Result code: " + resultCode);
// If the update is cancelled or fails,
// you can request to start the update again.
unregisterInstallStateUpdListener();
}
break;
}
}
#Override

unregisterInstallStateUpdListener();
super.onDestroy();
}
private void checkForAppUpdate() {
// Creates instance of the manager.
appUpdateManager = AppUpdateManagerFactory.create(AppCustom.getAppContext());

// Create a listener to track request state updates.
installStateUpdatedListener = new InstallStateUpdatedListener() {
#Override

// Show module progress, log state, or install the update.
if (installState.installStatus() == InstallStatus.DOWNLOADED)

popupSnackbarForCompleteUpdateAndUnregister();
}

And we're done!
Testing.
Please read the docs so you will know how to test it properly with test tracks on Google Play.
Long story short:
Sign your app with the release certificate and upload it to the one of publishing tracks in Developer Play Console under App Releases (alpha/beta/other custom closed track).
In your release track page in the Manage Testers section create and add a list of testers and make sure you checked the checkbox! - this step is optional since your developer account email is also a testers account and you can use it for testing.
Under the list of testers you will find "Opt-in URL" - copy this url and give it to your testers or open it yourself. Go to that page and accept proposition for testing. There will be a link to the app. (You won't be able to search for the app in Play Store so bookmark it)
Install the app on your device by that link.
In build.gradle increment the version of defaultConfig { versionCode k+1 } and build another signed apk Build > Generate Signed Bundle / APK... and upload it to your publishing track.
Wait for... 1 hour? 2 hours? or more before it will be published on the track.
CLEAR THE CACHE of Play Store app on your device. The problem is that Play app caches details about installed apps and their available updates so you need to clear the cache. In order to do that take two steps:
7.1. Go to Settings > App > Google PLay Store > Storage > Clear Cache.
7.2. Open the Play Store app > open main menu > My apps & games > and there you should see that your app has a new update.
If you don't see it make sure that your new update is already released on the track (go to your bookmarked page and use it to open your apps listing on the Play Store to see what version is shown there). Also, when your update will be live you'll see a notification on the top right of your Developer Play Console (a bell icon will have a red dot).
Hope it helps.
The Android Market is a closed system and has only an unofficial api that might break at any point of time.
Your best bet is simply to host a file(xml, json or simple text) on a web server of yours in which you just have to update the current version of your app when you post it on the Market.
Your app will then only have to fetch that file at startup, checks wether currently installed app has a lower version number and displays a dialog to warn the user he is lagging.
Another option you can use, if you want to avoid having your backend server to store your current app version like it's suggested in the accepted answer, is to use Google Tag Manager (GTM).
If you're already using the Google Analytics SDK, you have the GTM in it also.
In GTM you can define a value in the container for your app that specifies your latest released version. For example:
{
"latestAppVersion": 14,
...
}
Then you can query that value when your app starts and show the user update dialog reminder if there's a newer version.
Container container = TagManager.getInstance(context).openContainer(myContainerId);
long latestVersionCode = container.getLong("latestAppVersion");
// get currently running app version code
PackageInfo pInfo = getPackageManager().getPackageInfo(getPackageName(), 0);
long versionCode = pInfo.versionCode;
// check if update is needed
if(versionCode < latestVersionCode) {
// remind user to update his version
}
Take a look at this library that you can use to query the Android Market API
http://code.google.com/p/android-market-api/
You can use this Android Library: https://github.com/danielemaddaluno/Android-Update-Checker. It aims to provide a reusable instrument to check asynchronously if exists any newer released update of your app on the Store.
It is based on the use of Jsoup (http://jsoup.org/) to test if a new update really exists parsing the app page on the Google Play Store:
private boolean web_update(){
try {
String curVersion = applicationContext.getPackageManager().getPackageInfo(package_name, 0).versionName;
String newVersion = curVersion;
newVersion = Jsoup.connect("https://play.google.com/store/apps/details?id=" + package_name + "&hl=en")
.timeout(30000)
.userAgent("Mozilla/5.0 (Windows; U; WindowsNT 5.1; en-US; rv1.8.1.6) Gecko/20070725 Firefox/2.0.0.6")
.referrer("http://www.google.com")
.get()
.select("div[itemprop=softwareVersion]")
.first()
.ownText();
return (value(curVersion) < value(newVersion)) ? true : false;
} catch (Exception e) {
e.printStackTrace();
return false;
}
}
And as "value" function the following (works if values are beetween 0-99):
private long value(String string) {
string = string.trim();
if( string.contains( "." )){
final int index = string.lastIndexOf( "." );
return value( string.substring( 0, index ))* 100 + value( string.substring( index + 1 ));
}
else {
return Long.valueOf( string );
}
}
If you want only to verify a mismatch beetween versions, you can change:
"value(curVersion) < value(newVersion)" with "value(curVersion) != value(newVersion)"
For prompting Android App User to Update App if current version is not equal to market version, you should first check the app version on the market and compare it with the version of the app on the device. If they are different, it may be an update available. In this post I wrote down the code for getting the current version of market and current version on the device and compare them together. I also showed how to show the update dialog and redirect the user to the update page. Please visit this link: https://stackoverflow.com/a/33925032/5475941
