Android :: Reading Webpage Data
Sep 18, 2010
all in my application I want to read data from web page. if data at web page is upto 800kb then I am able to read it succesfully, but if data is larger then I get OutofMemoryException.I think it is because I am using condition as while ((inputLine = in.readLine()) != null) and in phone there is not much memory to read such a long string. I think I must have to read some part of string then write that part into some file in phone and read another part of string and write into phone but I don't know how to do that? Please help me solve this issue.

I'm working on an undergraduate level senior design project with the HTC Sprint Hero. We want to connect a device that constantly sends a serial string of data. Does anyone have any hints, tricks, or shortcuts to be able to read a serial string from the USB port and save it on the phone? I know there is not a really simple way but I'm no where near an expert in programming and wanted to see if anyone has come across anything that might help.

I'm writing an app that will periodically send information out to a remote server, and then get relevant information about other users from that server back to the local database.What's the best way to handle sending out this info (i.e.: XML or binary) and writing it to the remote server.Also,how can I assure that, when 500+ users' data get's to the server or FTP (or better alternative?) at once, the appropriate fields gets overwritten or added, without skipping any or overwriting the entire thing?

Do you know any application to prevent other applications from reading your personal data (contact, identity, history, ...) ? That would be great to be able to use our phone without giving away to unknown company/people our very personal data.

Is someone from Google able to advise when the Android SDK is likely to include a public API for reading/writing event data to the user's calendar? Searching the forums I see that this is a much desired feature by many developers but I haven't seen any indication as to when (or even if) this need will be addressed.

I searched the Incredible forums and sub forums and could not find an answer to this question, though I am sure it has been asked: If I want to go from my stock 2 GB card to a new card, and I want to preserve data AND have all apps still be able to read whatever data they were reading off the card, do I just transfer the files from one card to the other? I bet the only thing I need to make sure of is that new card is formatted with the same file system as the original card, right? I know copying data from one card to the other will preserve data, but I want to make sure I have no problems with apps, either, after inserting the newer card.

I have to create an app that draws a map reading data from a text file : for example the text file can be like
. index x y orientation
vertex 1 0 0 0
vertex 2 5 0 0.5
vertex 3 10 2 0.3
so i need to do in java something like fscanf does in c (fscanf scans the text file for known formatted data... example, in the file i written i know each line has a string float float float and i need to put them into a specific data structure that can be a list of elements "vertex"
next, when i have all the data, draw a simple image rappresenting the data..
my questions are...
there is a function like fscanf?
and then.. what's better for drawing the 2d map? i have tu use Opengl? At the end i have to draw the image pixel by pixel.. i hope there is something easier then openGL

I was hoping to make some shortcuts to web pages on my phone. I did make the shortcuts but the icons are blah. I was just wondering is it possible to make the icons more distinguishable, like the espn or cnn icon on the moment? I have any cut installed but don't think that it is the answer unless I am missing something in it.

I am trying to catch the intent that is fired when someone clicks on a hyperlink to a web page in the MMS browser. I have this in the manifest:
</intent-filter> <intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="http" /> </intent-filter>
However, when I click on http://www.ibm.com it only launches Browser. Same when I do
$ am start -a android.intent.action.VIEW -d http://www.ibm.com
in an adb shell.

When a user clicks the "about" button in my app's menu I want it to open the browser and go to a specific webpage. Is there like a one - liner out there somewhere to do this? Seems simple but Google is not being helpful right now - or I'm just searching the wrong thing.

I am just starting developing first app and not sure which way is the best fit for my needs.The key is to download a page source, get small part of it and display it using Android UI, with possibility to submit it later as a form action.The simplest way would be probably to ditch UI and go with WebView however I decided to parse it into UI, so no WebView for me.Currently I am trying to download page source using org.apache packages (from SDK Wiktionary simplified sample) and parse it using some regex (this will give me known incompatibilities when website changes layout but I am willing to go this way). Question is: is there a better/faster/easier way to pull the source of webpage (or part of it)? Or I will have to stick to org.apache due to the fact I want to submit a form based on user selection)? Maybe someone got a hold to more source code examples of similar app ?

I've come across a peculiar problem in one of my apps recently. I have a WebView that pulls down a webpage using loadUri(). This is being loaded into an activity that has just the WebView and a Button below the WebView inside a RelativeLayout. It works fine in the emulator on Android 1.6, 2.1, and 2.2. However, it does not show the webpage in Android 1.5. To strip things down to a bare minimum,
I used the following code from the API docs and tested it with similar results:
CODE:...........
Any thoughts as to what might be v1.5 specific that would cause this to not work? Am I missing something here?

Apologies if this has already been posted, but I did search the group before writing.
I am trying to launch an Android app via a hyperlink from an HTML site - i.e. tel:+448458001020 would call play.com from my phone upon clicking the button that has aforementioned hyperlink. Or putting a hyperlink on a button geo:0,0?z=17 opens up google maps on my phone with my location at a zoom of 17, mailto:n...@email.com would email and obviously http:// would take the user to another webpage.
Is it possible to launch an Android app already installed on the phone this way?
