Say I have data about customers and I initially have around 1000 pre-determined customers details I want to insert into my SQLiteDatabase.
Would it be wise to store that data into a text file in my assets folder with my own formatting (tabs to indicate columns and new lines to indicate rows), then just read the text file and insert the data into the database with insert statements? I feel this is not the best way and very in-efficient.
Is there a better way of doing this?
You can use the utility to create your SQL Lite database offline on PC, such as this:
http://portableapps.com/apps/development/sqlite_database_browser_portable
You can package this database along with your app and then put it on phone storage and continue from there.
You can do do in two ways..
Way 1:
You can make one .sqlite file with already 1000 customer records inserted in database and you can use it that .sqlite file from assets folder. Then you can copy those records in your internal database or use that only database.
Way 2:
You can put this 1000 records on server and call it by web service at first time app is launched..
Hope it will help you.

When I create an SQlite Database I dont find it in resources of my android project so I want to locolize it in my hard disk , and how to proceed to open it ?
You can't directly save your database into harddisk But you can create database in sdcard
then copy that database from sdcard to your harddisk.
Then you can access that database using SQLite Database browser
You have to do some selection from your database to see all records
here is a tutorial that can help you
i have to create a DIRECTORY in a database in which a few file will store.when user need any kind of file, the file fetches from that directory .
You can't cerate a directory in an sqlite database.
Either you create a directory on the filesystem using File.mkdir.
Or you create a table in a sqlite database. Here's a good tutorial.
There is no way to make directories in sqlite db.
Use android provided api for data storage read this tutorial.
Please first read about databases & then try to use it!!
Database:
A database is an organized collection of data, today typically in digital form.
Directory:
A directory or folder is nothing more than a location on a disk used for storing information about files.
I am a novice, and am creating a simple app that just reads data from a table in an SQLite database and displays on the GUI. (Just select operation )
During development, I created the database and the table from the tool "SQLite Database browser". And I inserted all data into the table through the tool.
Now, my doubt is ..
1) In java code, should I have some method that creates database and table ?? (For now, I have methods to do the select operation alone)
2) The database I created is located in my local drive. When the apk file gets created would the database also be included in the apk file ??
Pls help !! Thanks in advance !!
1) In Java code, should I have some method that creates database and table ?? (For now, I have methods to do the select operation alone)
No, You have to just copy your database file from /asset directory to /data/data/<package_name>/database directory. And only use select operation alone. You don't need to use create Database and table operation..
2) The database I created is located in my local drive. When the apk file gets created would the database also be included in the apk file?
For this, as I mentioned above you have to first put your database file into application's /asset directory, then copy it to internal storage (when your application start), then it works.

Copy your database file from /asset to internal databases directory /data/data/<package_name>/databases/, then use that database file.
