I have a doubt in XML parsing. I'm parsing a XML file. That XML file contains more than 14000 lines. I'm fetching 15 tag in that xml file. It is taking more than 7 times to fetch. Because 14000 lines * 15 tag. That much time it is taking. Any idea for this to reduce time. Or give some other coding to fetch xml data easily. No I'm using RSS Reader to fetch data as like in Java.

As far as I can tell, there is no API (official or unofficial) to access information about Apps on the Android Market (info such as Title, Icon, Description, Downloads, Comments, etc..)
However, there are a few websites that have managed to compile this information anyway.
My question is: How is this being done?
A couple of guesses.
Manually (not likely, due to volume) Implemented the protocol used by the official app (by decompiling or observing packets) Running some kind of debugger with the official app to extract the live data Using some kind of automation + screen shots + text recognition (seems complicated) Modifying the (open) source to write a log file
I'm just curious how this was done because I sure can't figure it out.

I currently building an android apps that retrieve data from a distant Web service and I search an efficient way to bind data form XML to ListView. I already use CursorAdapter and i search on the web for an "XmlAdapter". I read on Google IO topic "Coding for Life - Battery Life, That Is" (http://code.google.com/events/io/sessions/ CodingLifeBatteryLife.html) that is more efficient to use "stream parser" instead of "tree parser" but I don't find the way to build a class that implement ListAdapter because of stream parser can't navigate backward so I don't understand how implement method that use "position" parameter (How retrieve data before current XML Parser position?).
View 8 Replies View RelatedI have created a class with 3 sub classes in Java. The 3 sub classes contain variables to store information from my XML document. I am able to store in the first two for there are only single instances of the data in the XML. The third class contains variables that repeat multiple times. I want to store an object of "third class" objects. I also have a SAX parser class. I am doing this within an Android environment (1.6).
Does this make enough sense without displaying any code?
I have been in problem of the Activity life-cycle. All though i read lots of docs on it put on getting clear picture on it. I have Activity A. In that activity I have menu options. If we click any option it opens the respective activity like if i click on 2nd button it opens Activity B Now again Activity B has same options into it. When user clicks on 1st button then i need to go back to activity A. So using this. Intent intent = new Intent().setClass(context, Articles.class); startActivity(intent); So always it starts new instance of activity and fetch data from DB. I want something like Activity A can be resumed back as it was.
View 6 Replies View RelatedI was working on implementing a more advanced list view then the standard one they teach you in basic tutorials, and I did find a great tutorial explaining how to create your own Adapter and such not. http://www.softwarepassion.com/android-series-custom-listview-items-a...
I do have a working version of the tutorial and I am currently in the process of changing the list to suit my needs, but there are a few issues I am stumped on. If your run the tutorial code it creates a little progress dialog saying that it is retrieving data. In my application it is going to be fetching data from the internet and storing it in an ArrayList of custom objects. However if I where to rotate the screen the progress dialog pops up again, I have no clue on how to set it up so that when it rotates that it doesn't recreate everything and re-fetch the data and process it again.
In my Android app I need to extract data from a xml file (the file will have less than 2000 lines). I have no experience with XML parsing, so I don't know what the best approach is. DOM parser is perhaps not a good option, because I am on a mobile device. On the other hand with SAX I would probably end with more complicated code. What would you recommend?

As we know, the apps in the apple app store has a unique itunes link, and we can fetch app data about the app from app store through the link.I am wondering how can i achieve this in the android market, just like the website http://www.androlib.com/ did?As long as I know, each app in the android market has a ID, which just like "com.gabrouze.magic", and the QR Code can be viewed in "http://chart.apis.google.com/chart?cht=qr&chs=135x135&chl=market://search?q=pname:com.gabrouze.magic".

View 5 Replies View RelatedI have some xml files, and I keep them in raw folder. Now, the problem is that I have to use them with variable name according to my application condition. But I don't know how to fetch them. The main thing is that I am not getting that how to give the path of my xml file in application.
For example:
My file application.xml is stored in the raw folder and I have to access it with a variable name.
String xmlName= application.xml;
How can I fetch my xml through xmlName variable?

My application uses a urlconnection to retrieve a soap response. This XML is run through the default saxparser available in the java/android lib.
In android version 2.1 the XML is not parsed correctly. I fact there seems to be no parsing at all, while the raw input is available.
In android version 2.2 the input XML is parsed and the return result from my handlers is correct.
In short. SaxParser on 2.1 does nothing (no result, no error, no parsing), Saxparser on 2.2 works like it supposed to work.
Are there any work arounds for this problem ?
*Comment 1 by project member e...@google.com, Sep 14, 2010*
you can have a look at the differences between 2.1 and 2.2 yourself.
