JSON image to sqlite Android programming

I am new to Android Programming and would like to ask about JSON/sqlite. I have already parsed JSON text and store it in sqlite and then displayed the data in a listview in my app. However, I didn't parse the images in my JSON file (started with the easy part first). Now I have to do the image parsing and I have looked through many websites but still feel too confused about how to do it.
In the following link
http://www.androidbegin.com/tutorial/android-json-parse-images-and-texts-tutorial/
I have looked at how they do the image parsing but they're caching the images while I have to store the data into DB. In the link there is ImageLoader.java, MemoryCache.java, FileCachee.java,and Utils.java; these classes made me even more confused, do I need all of these for the images?
Can anyone please guide me like what steps I should follow? which classes of these do I need and which are not necessary?Or any kind of help.
Thank you in advance

To read in a single image, no you don't need all that. All you need is to read in an array of bytes (the contents of the file) and turn that into a Bitmap object. What all that is useful for is to hold lots of images at once- to make sure you don't use up too much RAM (MemoryCache), request them from the network more than once (FileChace), and to manage all of those (ImageLoader). So if you want to download lots of images its useful. For a single one its overkill.

Using an online .txt file as a data source

I am building an Android app for a client and most of the data that i need is contained in an online .txt file attached to my clients website. I've never used an online .txt file as a data source before and don't really know where to begin?! Can anyone point me in the direction of a good tutorial on the subject.
Many Thanks in advance
P.S. I haven't asked whether it's possible because i have assumed it is due to the fact you can use an internal .txt file as a data source

I think the best approach is to download the file on the device and then read it like a normal file. If the file changes on a period of time, then configure the app to download and read the file and then update the local info in the app.
I don't think you can use an online txt as a DataSource, but you can implement this so you have an abstract source for your file, and then just call read on it.

Expose the txt/xml file over web,if you want to get it down to phone use URL loader and load it to the phone and operate if you want to use it online (like others may also be using it) it will be a bit complex in order to deal with data coming from more then one source but possible. clear you question a bit more.

Can I use an sqlite database created for ios in android?

I would like to access the string-files stored in an sqlite database created for an ios application.
Any suggested methods to do this? I have searched all over the net but have not found anyone who has done this.
I know it is possible to convert a plist file to an xml file, but in the future the app I am working on will get all the resources (including strings) from a server.
I hope someone can help with this.

You could just include the SQLite database file as an asset in your app then use it like any other SQLite DB in Android.
You then mention that you will get resources from the server and I assume from your question that the data is currently in pLists so I think there may be 2 questions in one?
You might consider using JSON which, in many cases, is much faster than parsing XML. I recently used "Sublime Text" to convert a bunch of plists to JSON. It did a great job. v1 of my app parsed pLists. I tried SAX, DOM and the pull parser to find the quickest (SAX in this case) but, after conversion to JSON, v2 of the app is much, much faster. I haven't measured it because I don't need to. The user experience is enough. Where I previously had to use a loading progress dialog on a particularly large pList, with the new JSON parser, the UI is responsive at all times.

Converting SQLite to PDF

I am developing an Android application and got a SQLite database in it, which has quite a lot of rows and columns. Showing those inside the application is no problem, but I want to export the information of the database as a PDF file to upload it to Dropbox or the SD card.
I found a way to create a PDF file within the application from a bitmap file, but that doesn't help me much. The information of the database can only be seen in the application by scrolling around, as it is to big for the screen. Is there a solution for this problem?
Exporting a screenshot as PDF won't help me much as not the whole database can be seen within one screen.

I'd look for some reporting solution for example http://jasperforge.org/projects/jasperreports possibly on the server side.
You can also try iText which is very low level.

Generate the bitmap in your software from or in parallel with the generation of what the users sees, write it out as a file, and give it to the pdf generator.
