I would like to have a database of items stored on the user's phone. I currently have everything set up using WebView pointed at my domain, but obviously this isn't ideal if the user is in a low-signal location.
If possible I would also like to be able to search the list for multiple words.
Any pointers to tutorials etc would be ideal.
In Android you'll want to use SQLite databases, here are some places from where I learned my way with databases in Android:
Start here:
http://www.codeproject.com/Articles/119293/Using-SQLite-Database-with-Android
Or here if you want to use an existing database:
http://www.reigndesign.com/blog/using-your-own-sqlite-database-in-android-applications/
If you decide on XML, though, you might want to read this instead:
http://www.anddev.org/parsing_xml_from_the_net_-_using_the_saxparser-t353.html
http://www.androidpeople.com/android-xml-parsing-tutorial-using-saxparser
Here you have a tutorial involving both methods, downloading data in XML format, parsing it and storing the information on a database, probably the guide you want to read if you're starting with Android, since it covers pretty much what you are trying to achieve, probably :P

I was designing the classified app in android which takes the data from the db hosted at run time. I have designed it and it is working fine but it is very slow as application has to fetch the data from the server and which take much time. I want to reduce the time by some way that user get the data immediate and also can get the data offline with out internet.
Can any one suggest me the best way for store the data in the mobile app or any other way?
can i create a xml and store it on user mobile?
Please let me know.
thanks in advance.

One way is to do this by ContentProvider.
Another way is to use a framework like ORMLite, an Object Relational Mapping.
In my opinion you have two good methods . Fist one ;use store procedures ,triggers and functions to get data from database .Second method get data by using service like json do not use xml(soap).

I'm creating a website with an according app for iOS/Android and I'm doing some research for how I should do everything. I need to be able to post data from the different platforms and I want to access the same data from every platform, kind of like a wall where ypu can write stuff. I'm thinking that the data needs to be stored in a database but how do I access i.e. an SQL database from iOS/Android?
A simple research would've brought you a great tutorial on how to link a MySQL database through PHP to an Android app.
You'll be required the basics of PHP though so you may want to study a bit about that prior to starting.
Take a look at parse.com. This likely provides what you need without having to set up server with a database, etc. You can access your data on parse.com from iOS, Android, your web site, and a number of other platforms should you need to.

I am using this application: https://code.google.com/p/androidtutorial/ as part of learning to develop Android apps. I am totally new to this. In Eclipse I look through the source code, but I don't see the actual employee list (i.e. the file with the names/numbers etc). I'm guessing either I am looking in the wrong place or it links to a list held online or something? I'm sure it's obvious to anyone who understands these things, but I want to understand where the information is and where in the code this database/list is referenced.
Thanks
The list they are referring to is a local database on a computer, meaning you probably don't have it. It is just an example to show how to interact with a database.
I'm not familiar with that example project but I think the sql.xml file that is inside of EmployeeDirectory6/res/raw/ is where the data is coming from.
There is some code inside of DatabaseHelper.java that executes the SQL commands that are contained within this file to populate the database.

I'm quiet new to databases and SQLlite in general so I'm sure there's probably an easier way to do this but...
1) How can I store a database online so it is accessable by multiple devices? If this isn't clear, an example of what I'm trying to do can be seen on the Android app "whatsapp". When you update your status(i.e. set it as available or busy), it show's on everyone's device.
2) if this is too complicated to explain on here, can you recommend a tutorial series?
Thanks
Yes you can store your data on your online database but first learn about webservices and how it works. As for tutorial I think this one can give you an idea on how it will work:
http://www.androidhive.info/2012/01/android-login-and-registration-with-php-mysql-and-sqlite/
Also take note that SQLite database are stored locally on your device. :)

I am trying to build an online application for movie management. I want the application to be an online one, could any have inputs as to how to build it, as in currently i am downloading each of the dynamic content and loading the layouts which is highly inefficient. Could anyone suggest a better procedure to make an online application and guide for the same.
https://developers.google.com/eclipse/docs/endpoints-androidconnected-gae
That link will show you how to make a Google app engine project. The easiest way to use an online database with android. You can post, and get with very little code. What you do with the data you get back is up to you... Throw it into list views, text views, fragments, etc. But yes this is the best place to start as you need an online database or a social network would not work at all. I suggest you do the above totural and then come back with some more questions. Hope this helps!
