I'm trying to make an app for website that I DO NOT OWN OR HAVE ACCESS TO ITS DB.
The website is a forum community website and I wish make an app that can list the menu and the posts in a UI suited for mobile.
Also I am trying to see if I add real time notice function that will let the thread poster know when there is a new comment/post to his or her thread. (Website does not support this function)
Do you guys think I can achieve this through Jsoup or would I need other utilities too?
Also I am quite a beginner in java so the app cannot be too complicated.
Thanks.
It means that you want to write your own web browser! You need to call the Url get what it returns, parse it and show it... also you need to implement RSS to specific pages.. It means app need to call this url regularly and check if any changes or comments... Its do-able but wont really be efficient or bug-free... I wouldnt recommend it but as i sad do-able

I have a question that I would appreciate any on to answer.
my question is:
Is there any way to update some data like adding some videos, sales, values...etc in a recycle view after publishing the app in a google play without updating the app it self in the play store?
I actually don't have a clue on how to do this..
if there's any samples or websites on answering this question please share it with us.
thanks in advance
I can see a possibility but it's dirty, you can have one endpoint (/recycler), this endpoint can send you different type of data (movies, book and such), your application calls this endpoint and upon the result you parse it into one of your class that will populate your recyclerview.
I don't think you'll find any samples about it as it's not what people tends to do.
Well, if the data you want to update is writen in you code, I believe you can't update this without update the app itself.
It seems like you need a space on you app where you want to update it easily.
You should provide a backend to your app and consume the API to get all the info you need (with this, you will not need update the app itself on the store)
If you, like me, have no skills at backend development, give a chance to firebase:
https://firebase.google.com/
It will make easy to create a backend to your app. You'll need to update your app only once ( to make it work with firebase). After this, all you'll need to do is update you firebase, the app will get all new info from there
About me
I am a quite a starter but I have worked with Android Studio before; creating simple data scraping apps and more. Bu I was bashed on here once for just asking for answers without trying, that is why I am giving much as effort to make clean as possible. I am not looking for just answers, I was hoping to learn something building this app. Sorry for my terrible English and also thanks in advance!
Infinite Campus
If you haven't heard of Infinite Campus, it is a grading website which students and teachers use. The website is generally great; it gives a lots of informations and it is clean. Besides the website, they also have an app. But the app is terrible. Reason is:
It is Slow: refreshing the data takes too much time.
Less information: for some reason it has less information; like GPA and more.
On Android it just looks terrible
And I decided to create my own app, and hoping to learn new things in the process.
My App
I want my personal App same as Infinite Campus App.
The app is fairly simple, it is only does two things:
Log in
Scrape Data and Display.
The site is: Here
Problem/Question
I do not know where to start.
Do you guys have any good tutorials?
What do I need to learn?
Is the site good for such a thing?
Yes, you can create an Application like that but first, you need to understand your requirements and what are the technologies you are going to use like.
1.) In your Campus App you want to enable the login functionality for that you must have some database where you can store the user information like email and password for this Firebase comes handy with Real-time Database.
2.) you want to store the student's score or test mark for this Again you need to design a database where you can store it so Real-time database from firebase again helps in easy to use integrate.
3.) Next process involves making the UI in android which can be referenced in java where you can implement your business logic.

I have developed an Android game that integrates facebook SDK for checking if one has liked and sharing results.
I heard from my mate that he had problem that made him unable to use the like for reward feature on my app, so I decided to install facebook app myself to check out the problem.
For some reason if I am trying to access the fb api reading data from URL "https://api.facebook.com/method/pages.isFan?format=json&access_token=ACCESS_TOKEN&page_id=PAGE_ID" it opens up facebook app on Android which only flashes and then turns off.. How can I avoid this or is there better way to check if one has liked my page in order to give him reward?
I haven't used the Facebook API, but the Facebook app is probably opening because it's listening for broadcast Intents to "api.facebook.com". You could explicitly send the intent to a browser package instead, but this isn't a good solution as there are many browsers.
I would try to do a HTTPS request using a Loader to fetch and parse the json. Have you tried this yet?
I can't paste any code right now, sorry.
From your comment to above Answer , Glad to know that you solved your problem,
Here is the answer for your Question
is there better way to check if one has liked my page
You can surely use FQL - Facebook Query Language to do this, given under the developer documentation in Facebook site.
There are Two different table
1.Page - where you can get all the detail about the page
2.Page_Fan - which you can use to know the fan-id for the page
I have basic knowledge of Java but have never developed for Android.
A friend asked me for an app that seems easy enough to develop but I would need some help for Android.
All the app needs to do is send a text field (for example license plate number) to a predetermined SQL Server database.
Is this easy in Android as it sounds?
Thanks in advance. Cheers.
Darko.
That should be easy, but does it need to be a full-blown Android application for that?
Sounds like a simple webpage with an input-field and a submit button would do the job as well.
If you're familiar with using databases from Java the task is very simple. Just write the code that sends a string to a database. The exact same code you would use on a desktop Java application will do.
The rest is a matter of defining your user interface and obtaining the string. There is a good basic tutorial you can use on the Android developers web site: http://developer.android.com/guide/tutorials/notepad/index.html.
The number of code lines in the whole application will be in the range of a couple of dozens.
It sounds like you want the license plate information stored in a separate server, but if you also wanted to store some information on the device itself there is a simple Notepad tutorial provided by the Android Developers site that explains how to setup and utilize an SQLite database on the device. This by no means would replace the functionality of a server, but is another Android feature that is at your disposal.
Processing has Android support and it seems to be pretty awesome from my 10 minutes of playing with it. But I would like to make a regular (nongraphics) application like a twitter feed reader or something. So is there something like Processing that can do regular apps? Besides Titanium...
Basically I am looking for anything that will make coding for android easier, processing was so easy to get working that I was very happy with it, but it is for graphics only. Titanium didn't give me the same wow factor and it isn't open so that kind of takes away from it. What other tools are out there?
I'm going to give you the answer you are looking for and some advice.
Processing can do ANY of the things you are thinking about doing. If you want textboxes etc, you can use the Control P5 library. It's great. If you are an expert at Processing and just want to port over your Processing code to android, Processing for android is great.
But that's not what you want to do. You want to write an application. And you want to write it on Android. There are frameworks designed to give you a leg up in writing cross-platform mobile apps, but nothing is going to make writing an android application easier than learning Java and learning how the android stack works. It's actually really well designed and easy to follow once you start grokking "intents" and "bundles".
At the end of the day, you might even want to scale back a little further. Are you trying to write an application that needs to be used without internet access or that uses super special phone APIs? If you aren't, maybe you should try just writing your app as an html5 css3 website.
You can do plenty of input based stuff with processing. The original mouse events work as specified, except pass touches, but you can also access things like pressure and multiple fingers down. The hardware keys are also supported.
