I am developing an android app and in that I want to use a XML file. I think its a kinda web services and i want to use it in my app. so first of all i am thinking that whenever I open my app it fetch the whole XML file from http://data.gov.in/sites/default/files/Date-Wise-Prices-all-Commodity.xml and save it into assets folder of my App and then after I will use this XML from my assets folder.
I know this stuff is not too much difficult but actually i am new to android that's why getting this type of problem.
Please help.
Thanks in Advance.

You can't. The assets folder is read-only at runtime.
Pick a different location to save your data, see Data Storage for more information.

As posted in other answer you have to choose different location.
Rest method is as following.
Make a method or class to make http request.
Get response from given request.
Make a xml parser (DOM Parser,Pull Parser or SAX)
these are the basic steps. hope it will help.

android app with database?

I am trying to develop an android app with a lot of text for item.
For example:
-Item A,description: a lot of words...
-Item B,description: A lot of words...
What is the best practice to do?? Save that text in a database? And if a have 1000 words? Its good practice to do it? I searched in other applications that have the same context but did not find the folder database...So,I am confused..
If the answer is yes,what is the best practice for create the database? Insert onCreate() activity or create the database in third application and put in the app's folder?
Any help will be completely appreciated.

There are three ways to save your data in android :
Using Shared Preferences which save data using (Key,Value) pair which also used to save small amount of data.
Saving data into txt or xml file.
And finally save data into Sqllite Database.
you can go through the following links for more details about that Click Here
And for your case I suggest you go with saving the data into database and you can do so by start reading this tutorial click here, and this, and this.
Hope this help.

Create an output document from Android App

I have an android app where I will be capturing various information in different forms and storing into the SQL lite database for tracking/viewing purposes. I want to give the option of exporting the information into a RTF/PDF/Doc and give the option of sending it thru email.
I looked at various similar questions posted here earlier but didnt get a definitive answer. I saw the Android PDF Writer library http://sourceforge.net/projects/apwlibrary/ but this seems very basic. I considered iText but I think there would be issues with licensing if in future I want to sell this app..
Basically I want to define a template document with a structure that will be copied and content added to it based on what the user wants to export...
Any help is greatly appreciated...

I wanted some elegant solution where I can store a template in the assets folder and replace whatever I want to create the output document. Finally I went with html. I created a html template and put it into the assets folder. After that it was as simple as read assets, read db, do string.replaceall and write the output html and email it out.....

OpenOffice.org's Universal Network Objects (UNO) interface to programmatically generate MS-Word compatible documents (*.doc), as well as corresponding PDF documents.
its basically java so it should work on android too.

How to storing data in my own application

I would like to build some simple application - for example Todo list - and I am thinking about the problem and its solving - how can I to store data in my own application on Android platform?
I should to use some text file, xml file or some database? What will be better for beginner on this field?

You'll have a VERY hard time getting anywhere with Android if you don't read through their website/dev resources. I would highly recommend visiting their site.
As far as data storage is concerned, that varies based on your need. Explained here

My suggestion is to use SQLite that comes with Android. http://developer.android.com/reference/android/database/sqlite/SQLiteDatabase.html

In my opinion, a SQLite database seems most appropriate for this kind of application. There is lots of support for using the SQLite database in conjuction with ListViews (which I imagine you'd want to use in your to-do list app).
In case you haven't already checked it out, see the page on the developer site:
http://developer.android.com/guide/topics/data/data-storage.html#db

Theres a few ways you can store data. I've created a few applications thats store data using shared preferences
They're quite handy for storing strings, ints, bool values etc. However if you have a large scaled application, that requires better database management, I would look into sqlLite.
Android has supported classes and functions to help access/store the information.
Theres a good tutorial on the android site called notepad that takes you through how to use sqlite.
That should get you started :)

Look at this Thread klick
Edit: its cool for less data, if you want to store and browse lots of data, you should use as SQLite Database

Using a file, database or xml based depends entirely on what kind of application you are building. For eg: If you parse an XML feed and store the results back in an XML file - it totally defeats the storage purpose!
Databases are used to store structured and related content like - news feed results, email client data, etc.
Files are more used for storing raw / binary content like storing images, attachments, etc.
BTW, if you are a beginner - you should try all of them! :)
Hope this helps!

Read HTML file from Website and convert into App

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.
Thanks for your help

It seems overly complicated to me. I wouldn't handle all that using Android. I'd crawl the data on a machine (server) and then I'd convert all needed data to JSON and have the Android (client) fetch the data using a simple JSON parser.
In my opinion that would be the easiest solution if you don't have access to the server the website is hosted on to get it generate a JSON feed for you directly.
EDIT: In answer to your comment Boardy.
Here is the official website of the JSON project in order to get an understanding of what it is. Then if you have access to the webserver providing that page (I assume it is a PHP based site) and want to modify or add the functionality of providing a JSON feed then you should also take a look at the PHP JSON documentation.
To parse JSON on Android check out this SO question and also don't forget to take a look at the official Android documentation on their JSON implementation.
