I want to make a samsung smart tv app with tizen.
I've made an webpage using springboot.
I tried making the app using that webpage codes I made, but I've got to know Tizen doesn't support java but html, css,and javascript only.
So I used meta http-equip="refresh", and let index.html go to my webpage url,
but there were long loading time, and ugly ui for a waiting page..
also remote control's pointer was weird. (not focusing on a certain button, but there is a cursor)
is there no way to solve this problem?
I've tried to find a way but I couldn't. please help me...
It seems that you are making a redirect to your website (hosted in internet).
Maybe would be better starting reading the basic concepts about Samsung Smart TV apps here
If you try to open external content (hosted websites) into your app the TV will use its web browser to open it.

Helle everyone,
I'm wondering if there is a possible way to share a text On my Facebook profile, even while using the codenameone simulator.
I did my researchs but all what I find is the share using the "ShareButton" component which only works when you launch the app with an actual device.
Greetings.
The share button doesn't really know about facebook. It places the text into a special OS hook which offers you venues where to share that data. That's great because that means it can work for other social networks seamlessly and it uses the native OS to do the posting. Zero setup.
Desktops don't have an API like that. If you want to explicitly share to facebook you can just do something like this which will launch the browser:
Display.getInstance().execute("https://www.facebook.com/sharer/sharer.php?u=" + Util.encodeUrl(textToShare));
I am working on desktop based responsive web application where UI/front end will be in HTML/JS and back end point will be either servlets or struts/spring controllers.
My question is say after 3 years i want to have android mobile app , can
I continue to use my servlet as back end code and serves the response coming from android mobile app,
Mine understanding :- I will develop the native UI part(wherever it is required) using android SDK which then can communicate with existing servlets .
Then android app on mobile can render the html returned from my servlets or servlets can return the android specific views. so changes are required only whenever i need custom views(htmls or android specific views) for my mobile application. Is that right ?
after 3 years... can I continue to use my servlet as back end code and serves the response coming from android mobile app
We have no way of predicting the future with accuracy.
Then android app on mobile can render the html returned from my servlets
To render HTML in Android, you use WebView (or maybe a third-party library, though that is uncommon). WebView handles lots of stuff but not everything that a desktop browser does. How well that all works three years from now is unknown, and how well it works today with whatever your Web site does is unknown.
or servlets can return the android specific views
No.
so changes are required only whenever i need custom views(htmls or android specific views) for my mobile application
Can you get that to work? Possibly, but the details will depend a lot on what your existing Web site does and what sorts of client-side technologies it depends upon. For example, Android does not support Flash. There are also technical and security issues with interoperating between Java based UIs and WebView-based UIs, though this is a bit better in your case, as you are only hitting one server (I think).
All that being said, I would never write an Android app this way, and I would never recommend anyone else write an Android app this way. I would revise the Web server to have a proper Web service API, and I would write a native Android app that uses that Web service API, not using servlets returning HTML. The primary place where I would use WebView is when I had material that only exists in HTML, typically because I did not create the HTML in the first place (e.g., user-generated content).
Primarily mine question is can I continue to use existing servlets. I don't think its based on opinion. It should be either yes or no
Of course it is not "yes or no". We have no way of predicting the future, and we know almost nothing about the Web site. Your question collected two "too broad" close votes, and that is a reasonable assessment.
I am currently using a webview to load a webpage which contains lots of javascript and having lots of trouble debugging what exactly gets loaded and when in the webview .
Then I saw this post where the op seems to be using apache log to monitor webpage load events in his webview.
Enhance webView performance (should be the same performance as native Web Browser)
Can I get a similar utility plugin or anything so that I can use it with logcat in ddms view.
If possible please provide some resource as to how to configure it for android.
I think the OP is using a remote access tool (ssh?) to connect to his server and is viewing the Apache log from there.
You could try subclassing WebView and providing your own implementations of onLoadResource, onPageFinished, and so on. That should give you some idea of if/when things are being loaded in the WebView.
I have little knowledge about web programming, and I was looking through a lot of examples which gives alot of examples about writing on the webpage for web browser to see, but nothing about getting request when user presses a button the webpage.
For example, upon opening the server, it opens the port 80, then I want to go to web browser and type "localhost:80" to access the webpage made by the server client. The webpage has a button which when I click it, webpage changes to something else like "Clicked!".
Can someone show me an example code of this? Link to an example would be great as well.
Thank you very much.
I would recommend using something like Apache's HttpClient to imitate a button press, which is just an HTTP POST. And if you don't want to use a third-party library, the standard Java library already rolls its own.
I have read the Blackberry documentation and it is possible to push a notification from a webapp. I am planning to create a Blackberry application that compliments to our webapps. But I am still left in the middle whether to develop a webapp or native Blackberry app. I have also look at how a webapp runs on Blackberry browser and it looks smooth.
From your experience does the native app offer something that the webapp doesn't? Bonus question, is Facebook and Twitter app on Blackberry a native app or a webapp? If it is a webapp, is it possible to make a launcher for the application on Blackberry?
Thanks for your help.
Facebook and Twitter are on both types. The web apps are just a website formatted for a small screen so anything you do in say asp.net will show on a blackberry web app if you program it to. The native app just feels like part of my phone. You can save data on the phone so if your app is a relating to news or something that would be stored I can read it offline or slow connectivity (camping, rural areas, etc...). It can also interact with other feature that blackberry offers such as contacts, email, media player, etc...
If you would like to save anything for the user to view without pinging the internet a native app would be preferred.
It's possible to create a launcher but I haven't created one so I'm not sure of the details. I would assume it's just an app that opens the browser to your URL.
One more thing about a web app would be if your application stores users settings (twitter auth key, etc...) they would need to be stored on your server and not the users phone adding more expense and maintenance.
Good Luck.
Widget is not supported for device software less than 5 , you combine both of web and native development by using browser field ,but you need to consider that its Java Script support is poor
Let's not forget that the blackberry browser is really bad as well. I don't know any BB users who would want to use a web application because of that.
When it comes to native apps, you have some choice however and you are not restricted to java (depending on which OS version you want to target). In addition to the mentioned Java, you can use Widget (link for resources) that behaves like a native app, but can be accessed like a web app.
I was just at innoTech and they had a whole session on this topic. But instead of recaping it let me just post the funny video they showed at the end which sums it all up.
