Thank u in advice.
So at a guess you are using a pre-populated SQLite database? You could use SQLCipher to encrypt the database - it works with pre-populated and new ones created by the app.

This is the logic I am trying to achieve:
Download the database from web services
unzip it
load the database using SQLite asset helper
delete the zip file
I am wondering if it is possible to achieve using SQLite asset helper, or I should use other method?
SQLiteAssetHelp is designed to copy the database file from the assets folder, which is part of the shipped app package.
You already have the file; copying is not necessary.
Just open your file through SQLiteDatabase.

No, sorry.
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.

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