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.

How can I copy/clone a views automatically in android studio
for example, I have one imageview and a textview. how can i clone them on runtime with different values alongside with existing objects like them.
I tried to make invisible views and and update them later. but I don't think its efficient way. plus it is also limited
I'm fetching data from JSON file. which will get a text description and an image link each time I update that file online. so I want to update that in android app too! but unfortunately I can't do with single textview and single imageview. so need to automatically make them whenever the data is updated online.
if there is any other way of cloning views. kindly tell me.
First of all read this How to ask? , it's really hard to understand what you want us to help you with.
If i understand you correctly you want to display some kind of a list that updates when u update your JSON/Online database.
If that's the case I think the best way to go is RecyclerView
it's basically an efficient way to create a dynamic list that can be updated at runtime
And here is a nice tutorial you can use

I read at the Android documentation, and the "sqlite helper" is crazy complicated! Is there a way to not use it and maybe use standard sql commands instead? I come from the php mysql, that's my reference; I took a look at the php sqlite too and it also looks much easier.
UPDATE
Thanks soulreaver! Now, another question:
When would I want to use the sqlite helper ? what are the benefits ?
You can always use raw SQLite queries RawQuery. I can agree that sometimes for simple tasks using SQLiteOpenHelper doesn't help at all (It is usable for more complicated things though).

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!

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
