I am trying to fetch sms messages from inbox, sent items and drafts. I would like to do a pagination for my list view for that it's imperative that I fetch records in pages/chunks.
I am not familiar with sqlite which is the database I understand android use to store the data. Can someone tell me how can I restrict the number of records I am fetching by using contentResolver.query?
Also what is the way to pull the sqlite database file onto my machine and browse/query it locally to experiment or see data on my machine?
Are there any other better ways to implement pagination in android?

I have this query which does work fine in MySQL
CODE:............
Distance is in Kilometers, the input is lat=12.345 and lon=67.89
The SQLite is 3, and I can't run custom functions with it as it's on Android. I also don't have acos() etc... as that is not part of the standard SQLite.
How would be the above query in SQLite?

I am currently trying to store an image into the sqlite database as a blob and retrieve it back.I am not sure if this is the correct approach since i dint find much of sample codes related to inserting images in sqlite. I am able to insert values but when i try retrieving them as byte using decodeByteArray it gives me the following error. DEBUG/skia(13003): xxxxxxxxxxx jpeg error 53 Not a JPEG file: starts with 0x%02x 0x%02x.The image retrieving query works fine as i have checked retrieving an image previously stored as blob in a sample database.I have tried storing and retrieving different image files but i am getting the same error.Could any one tell me as how to solve this problem

i have a problem with double values i need to store in an android homed sqlite database. since these double values represent gps values (lat & lng), i really NEED an absolute precision down to the 9th number after the comma.when reading lng from this table into some (java) double variable, i get a value like "0.999956837" - this renders the values pretty useless to me.is there a way to enforce the precision i need other than storing the values as "text" fields (what would make expensive casts neccessary) or storing them as integers (meaning i need to multiply/divide at each write/read-op)?

I am developing an application for android phone, In this I need to use at least 400 audio file which can
be played for some respective texts,Now my question is which is the optimized way to do this.One solution is putting all the audio files in the resource folder and referring from there, this will never be a feasible solution as the application size will increase. Is there any way to convert the audio file into some format and dump into the SQLite database and retrievr flexibly.

Suppose, you have a larger database of customers, such as 5000 records. Using a simple select query it can take 2-5 seconds on a mobile application to populate a listview with all thousands of customers available. But the user only needs to select one, so what is the best way to select the customer?

I want to use the SQLite clause LIMIT and OFFSET, so that I can fetch my records in pages. But, though I can find the LIMIT clause in the SQLiteQueryBuilder.query() which would effectively limit the number of record in my result.

My ultimate goal is to limit records that are able to be created so that I can have a trial version of my application. I'm thinking I can do this rather simply by returning an int variable within a sqlite count statement, and using a simple IF statement to determine if a new record should be created.

I created a database with records in it and everything. I am trying to use its fields and put it in a spinner. The database contains university names.
I created a spinner with:
CODE:............
where I am feeding the spinner the records from an array. I want to do it from the database that I created. I read thru the classes and there are 2 ways but I can't find a proper code to use any of them. I just want to insert the code to get records from the database. It shouldn't be complicated is it?

So i have been recording a good amount of pool side videos in 720p on my EVO. I usually home movies through my western digital tv box with all my movies loaded on portable hard drives. So today i decide to take some movies from my phone to the hard drive and i realized that the phone records in 3gp. Why 3gp? That may be an old cell phone format but its not what todays 720p movies really record in. Does anyone have any recommendations for a conversion software or file type to convert these movies. It seems kind of useless to record movies that can only be watched back on a computer. And i know its not a canon hidef camcorder that cost over 1k. Its a cell phone.
