I am not sure about the concept. Please suggest the best way to do this.
you can use shared preferences to save local data, to check it in file folders manner you can use DDMS. You can also use SQLite.

I have an app that just need to read from a database. I do not want to parse a big file in the app because it takes a lot of memory.
So is it possible to populate a database and ship it with the app?
Just parsing the file and storing it in the app the first time the app is run will not do since it will create the same memory problem.
An alternative would be to have the database on Google Appengine but I would like to avoid that because the app would be unusable if there is no internet connection and there are costs for the traffic.
So is it possible to populate a database and ship it with the app?
Yes. Create a SQLite database containing your data, then package it with your app using SQLiteAssetHelper. It will be unpacked into position when you first try to use the database.

How to sync SQLite database on Android phone with MySQL database on server?

I am new to using services. In my application I want to run services in the background. I am creating the same database in MySQL server and SQLite. If I change some data in a table in the SQLite database, does it mean it should automatically store the change in the MySQL-server also?
To answer your question: no, it does not automatically reflect the changes made in SQLite into MySQL.
Why? Because you basically have 2 different databases, although they have the same name (and probably structure). In order for them to communicate and get synchronized, you need to implement some kind of communicating mechanism.
As suggested to you by eggyal in an above comment, take a look here, as a solution for this kind of problem is explained there.

I have seen many solutions which are code oriented, like if you have to create a table, you would have to create it using code, but this is not good for complex applications, as we have SQLite Browser to create database and its tables, and it generates a database file.
Now the question is, where to place that file in my project, there is no data folder in eclipse project, I dont know what to do, its interaction is not like MySQL where we use driver or connection?
You can follow this steps to use an existing database in your application:

I've also made a blog post some time ago which combined the solution above with the use of ormlite:

I've created an sqlite3 database and a number of tables using SQLiteManager 3.5.1. However, i've no idea as to how i should be able to connect, access and use the database. Moreover, i also want to be able to modify the tables and the data in the tables. Is it possible to put the database (with the .sqlite extension) within the assets directory and work back and forth from the android to SQLiteManager?
Yes, it's possible. Here it's explained:
