Android :: Options For Pulling Data From Website?
Sep 28, 2010
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?

partybets.com wont allow me to click on games or events to bet on but I can click it but it does not load up on the side so I can actually make a bet. Every other site works and this site is one of the main reasons I got a smart phone, to make bets.

I am not yet an Android phone user but I am thinking about it. I currently have a Palm phone and I have used palm os for several years. What I appreciated with palm is the good data security level, for example some records can be hidden and opened only by entering a password. Is that kind of functions available on android phones?

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?

Just wondering what would be the best way to grab the following data and parse it.Here's an example of some the data I want to pull.
<?xml version="1.0" encoding="UTF-8" ?>
<eveapi version="2">
<currentTime>2010-11-19 19:23:44</currentTime>
<result>
<rowset name="characters" key="characterID" columns="name,characterID,corporationName,corporationID">
<row name="jennyhills" characterID="90052591" corporationName="Imperial Academy" corporationID="1000166" />
</rowset>
</result>
<cachedUntil>2010-11-19 20:20:44</cachedUntil>
</eveapi>
I've seen some examples on how to parse XML data but they are all based on if statements and that's a lot of hard coding is there a more genertic way to do this?

I'm looking for suggestions for ways to share Android app data between phones running the same app. For example, lets say I have an app that stores a database of book reviews. If person A has a book review that person B doesn't have, what are the options for getting that information from person A's phone to person B's phone?
Currently, I'm aware of the following options:
- Upload data from person A's phone to a server, then download data from server to Person B's phone.
- Write code to have the phones sync up using bluetooth
- Write code to send SMS messages
I'm wondering if there are any more options besides these, and if there's actually a best-practice for accomplishing this?
Ideally, I want the users to simply click a button in the app to make the sharing take place, so I don't want to go down the bluetooth route because that requires the user to do a bit of setup (or assumes they already have set things up in the form of bluetooth settings).
Since the data can be of variable length and potentially large, I believe that would rule out text messaging.
As far as the server route goes, from what I understand this seems to be an ok way of doing things, but my problem is that I have no experience with having users potentially sign in to a server and then uploading data. I don't know of the cost concerns (if any), or of potential security concerns (allowing just anyone to upload data, I'm not sure if I would have to take steps to ensure someone couldn't bypass the app and upload malicious data).

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 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 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.

After upgrading to CM10.2 nightlies, I noticed that neither of my purchased back-up apps function as intended anymore.
ROM Toolbox Pro fails to backup phone data (such as SMS, accounts, dialer info... etc.), and Titanium Backup gives me an "insufficient free storage space" error any time I try to back up my apps. Now, I've already tried pretty much everything with Titanium Backup outside of installing SuperSU. I've changed the backup directory to every combination of emulated/legacy and sdcard0/legacy... etc. The only thing I can think of is that it doesn't play well with Koush's SuperUser app, but I don't want to bother removing it for SuperSU because it's integrated into the ROM nicely.
So is there any way to get Titanium Backup working properly with 4.3 ROMs? I'd like to use it ideally because the update.zip function really makes it the best backup option out there when it's working right.
Otherwise, are there any other backup apps that can backup apps/data/accounts/SMS with 4.3 ROMs without problems?

I'm using the following code to grab images from the web. It uses Gridview and depending on position, picks a URL from an array. It works but the loading of images is often hit or miss. Almost every time I start the app, a different number of images load. It also has issues when changing from portrait to landscape view, 5 out of 10 images may be displayed then I'll turn the device and usually lose all the images. Sometimes a few do show up though. Any ideas on making this more robust?
try { URLConnection conn = aURL.openConnection();
conn.connect();
InputStream is = conn.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
Bitmap bm = BitmapFactory.decodeStream(bis);
bis.close();
return bm;
} catch (IOException e) { Log.d("DEBUGTAG", "error...");
} return null;

I have 50 XML files located on a remote server, one formatted for each state. I am able to read each of the 50 files by selecting a state from a spinner and using a SAX parser but I cannot seem to find out how to pull out information from each file by city. I have tried unsuccessfully to pass a city variable to the characters method of the Handler.
Each state has thousands of records and I am looking for a way to speed up the search since reading the entire file for a state takes several minutes. I used SAX since it was supposed to be the fastest way to read but it limits me in selecting specific information. If I understand things correctly I could use a DOM parser to find my state and city specific data but that would make retrieval even slower.

After I updated to android 2.2 awhile back when it came out, I started having trouble with my pull down notification screen. Simply put if I'm holding the phone vertically the notification screen turns horizontal like I was holding it in widescreen. Anybody know how to fix it? I did the leveling thing a few times? Also, I have the default clock set up but it says I'm in a city that is about 15 miles from where I actually am which is throwing off my auto wi fi enabler. I have my location set up to be determined by GPS and network. Do I need to turn one of those off or do something else? Also, can somebody tell me where on the phone I can change the battery warning and yellow and red indicators to different percentages?

I got the upgrade to Froyo yesterday AM.Twice during the day it unlocked and I had a msg "Loading" while my icons loaded. Then this morning it did the same thing, but it didn't have the name of the program under the icon, plus my buttons for "Phone" weren't there.So I pulled the battery and it was back to normal.I've never really had these issues prior to the upgrade, but if rebooting is a part of the process then I'm curious if there is a way to reboot without having to pull off the case, separate the back door and pull the battery out. Anyone know?

I have two questions about the N1. Whenever I forward emails from the native email app they forward as attachments. This is not acceptable in a corporate environment. I cant find a setting for this, am I missing one or is this the intended functionality? Also, I tried cc'ing a distro group in an email today, and it would not pull the group off exchange, so I had to switch back to my iphone to send to the proper audience.
