Android :: Application Design - Accessing Website Data
Oct 19, 2010
I am new to Android development and am interested in working out a design of an application. I am however, unfamiliar with the best way to handle what I want to do. I am interested in obtaining information from my band's Joomla website and placing it into an Android application. At the moment I'd like to get News articles posted and potentially other information that I create on the site. I was thinking of doing this by setting up RSS feeds for the website. Would it be better to somehow access the data directly by connecting to the database? I don't know PHP so I can't develop a webservice to access the content. Any ideas?

I have seen few apps having exact same UI when you access the app through stand alone app or through their mobile website. What are the pros and cons of both approaches while developing the app?

I am trying to make an application in which I need to fetch some data from an website. Do we have some sample application which demonstrate how to do this? I do not want to open the website from browser, just want to query through java code..and get the result.

Is it possible to programmatically access the website that is currently displayed within the Android browser?
As far as I know the native Browser doesn't handle plugins (please correct me if I'm wrong), so I thought that reading the browser cache would be an option. Is there a more sophisticated way to get the currently displayed HTML?

I picked up a Samsung Moment through Sprint back around June. I wanted the new Sprint 4G phone but figured I would make due with the Moment until the craze died down. Anyhow, I own a small firearm forum,Semi-auto Rifles. This is my main reason for going with a driod phone. It allows me to monitor my site away from home without popping out my laptop. Well for the last 2-3 months the Moment did it's job flawlessly. I was able to use it to maintain my site...even when my cable modem blew up one time and some cable guy disconnected our cable by mistake.My problem started this past weekend when all of a sudden my Samsung Moment started having issues locating my website. I keep getting the same "Web Page Not Available" message. Now sometimes it will allow me to access the home page and then freak out on the forum index page. This is the only site I have trouble with, I can access any other site and surf until I'm blue in the face. I took my phone down to the local Sprint store and they said my phone was out dated. So after 15mins and deleting all my Apps, they had my phone working again. Then come about 2-3hrs later, I started getting the same Web Page Not Available" message. During the whole time my site has been up and running with zero issues.
Anyhow, does anyone have a clue? I'm lost and this phone is worthless if I can't even access my own website. While I was at the Sprint store, I started tooling around on the new HTC 4G phone. It pulled up my web site and worked for about 10-15 minutes before it started giving me the same dang "Web Page Not Working" message. So I'm not sure if it's a phone thing or a Sprint thing? Then for the interest of Science, I started surfing other related forums to see if maybe Sprint was blocking firearm forums. I was able to tool around on other gun forums for about 10 minutes with zero issues.

I am going to develop an Android Application but before developing it i needs to have MockUp for the Android Application,so is there any way to design MockUp/GUI Design tool for the Android Application?
I know about DroidDraw tool , but i think it is not the exact way to prepare Mockup for the android application.
I have already referred this SO Question , but overthere i just found all the tools for the I-Phone only. So please feel free to share with me if you have/found any !

I am working on developing an application that requires me to establish multiple client-server based connections. Connection can be of two types where the Android device can be a server or a client. I can have up to 6 - 8 connections. Once the connections are set-up they need to be running in the background and are not typically affected by UI actions.Since each connection can be blocking, I am wondering what is a good away to design this app. Should I have two services for handling the server and client connections? Each service could have a "connection manager" that can spawn new threads when necessary. Or does creating two services even help? I presume spawning new processed would not be good as they will be expensive. Is this correct? I would appreciate any suggestions. Also, if this use case is not typical please let me know if you need more information to make any recommendation.

I haven't done any work with the Android or iOS platforms, but I have recently been pitched a project and I'm trying to see if it is even feasible.
Is there currently API hooks in the iOS and Android platforms for accessing / manipulating the voice / data streams? What I would like to do is encrypt all outgoing steams and decrypt all incoming streams before they reach and other processes that need that data.
I would assume that because the Android platform is open source one should be able to do this, it just may have to be hacked together. I'm more worried about iOS.

I am experiencing a problem with accessing an application from the Android-browser. The application uses DWR to persist connections to the clients that are connected with it. Everything works fine for me, except that if the application does not send any data to the client on the Android-phone for 2 minutes, the connection seems to be lost and no data arrive at the client. The same scenario works just fine on Firefox, Opera and Chrome. If the pause between two data transfers is less than 2 minutes, it works just fine.
So, now my question: Is there some timeout setting for the android browser that I am missing? Or is this some built-in bug/feature/whatever that I cannot circumvent? I know that I could prevent this from happening with some sort of heartbeat, I would just like to why this is happening.

I want to build an application that is able to read .CSV files. These .CSV files are downloaded NOT from within the application but just the regular Android browser. Now, when I start my custom application, is that download available to me? Any examples?

I'm building an Android application that needs to communicate with a MySQL database. The application isn't meant to be published, and I want the application to be the only thing allowed to interface with the web service I'll create for DB access.
I've been thinking how I can secure the system, and this is the idea I've come up with. I'd appreciate any feedback or other ideas. Surely there is a method built into Android that I am unaware of.
My thought is to give the web service a GUID. Each time a call is made to one of it's public methods, the web service matches its GUID with the GUID given to it by the Android application. If the GUIDs do not match, the web service refuses access. In short, my system has a 128-bit password.

I have read the topic about supporting multiple screen size as well as different DPI. I am wondering which of the following way is better in supporting multiple screens:
1. Have different layout for different screen size (stretch the images)
2. Have different set of graphics for different screen (use the same layout)
3. Have different set of graphics and different set of layout for each of the screen
Which way is the easiest? And which way is the most optical way to design? Or is there another better way?

how do you stream certain bits of information from a website. From what I understand webview launches a web page, but what if I want to only stream a paragraph that was published on a site. Example: Yahoo! Fantasy Football. Updates on players and the news feed about them.This is obviously a lot more complicated than my question. I would be interested in a tutorial that could walk me through this. Does this also take programming on the server side to send this out?

I was wondering what the best approach is on Android to retrieve information from a HTML page hosted on the internet? For example I'd like to be able to get the text from the following page at the start of each day:http://www.met.ie/ forecasts /sea-area.asp I have been downloading and parsing XML files but I have never tried to parse information from a HTML type file before.Is there a native way to parse the information I want?Or do I need a third party library?Or do I need to look into screen scraping?

I am looking into developing an App that will convert a website into more readable data for an android app. I am at university and have an online notice board which can be viewed on the web but if possible I would like to transfer this into an app on android to make it more easy to read on mobile devices.
What I thinking is that the app would go to the website where the notice board is held and read in the html code to display each notice in a list adapter view. Each notice is within its own div so I assume I could use that to split each notice up into its own button on the list adapter view. Is this possible and if so how I can go about doing this. I have tried google for an answer but I have not yet found a solution to this problem.

I'm making an Android Java app game (although this question applies to all languages really) and hope to release the first version soon. I'm nervous about how I save data in my game. My problem is that, if in a later update, I decide to store more data or store the same data in a different way, I need to be careful I don't lose or corrupt data for users that upgrade (i.e. I want users to be able to use data created by an old version in the new version, like their high scores from before).For example, say I want to save high scores in version 1.

I just got a Hero, its really cool, but I'm worried about how much data this thing is going to eat up. I've got a 500MB limit, but I dont really know how long that will last. So heres a few questions
How do I know if the phone is accessing the internet through WiFi or not? Obviously WiFi doesnt count towards the limit, so I want to know that I'm using it as often as possible.
Do widgets on the home page count towards your data limit? I've got a weather widget, facebook, bbc news, email, all getting their info from the internet. Is this going to be raking up the MBs while the phone is just sat in my pocket?
Is there a number I can ring to see how much data I've used? I'm with Orange. A number to call to check my texts and minutes would be helpful, too.

I am new to android programming and have a strong keen interest to learn it. I want to write a program that fetches the data from a website, segregates it and displays it on the screen of the phone. The data could be grocery list from a supermarket or sale items in a mall. Could you please suggest as to how I can go ahead and start this.
