I have finished the notepad tutorial on the android site. I did this because i want to create a DB for my app. Once i finished i found out where the data is located in the DDMS. Then..
I downloaded the SQLite browser database i created a mini DB. Know i am trying to put this data into my project.
Can i put this new saved database file(i made with browser)into the notepad database file & and delete the old one. So when the emulator loads it will load my data.
Because i made a database with android notepad with all the code etc. with this SQLite browser i am thinking the code is done for me(table, columns,)
I guess am asking you is can i just make a full database with sql browser and just input it so how in my project.
Your database class needs to be specifc to your database, so you cannot just change databases on the back end and expect the handler class you wrote for the notepad tutorial on the front end to work properly with it.
That being said, you can create a handler to run your custom db. It's rather round-a-bout though. After you get the helper class created, you have to put your db into the assets folder. In your db helper you need code to copy the file out of assets to it's proper home in your applications data directory.
You can find instructions on how to set up your database so the Android framework can use it properly as well as code for copying it out of assets to your data directory here.

Background:
I don't have any knowledge in Android. I want to develop an app with 2 forms, one is to take customer data and one is to search the data. I can do this app in web or in Jface/SWT but just want to check feasibility of writing it in Android.
Problem statement:
Can we create an app in Android like mentioned above with SQLLite DB? but the data should be accessible from another android device with same app. i.e. my DB will be hosted on one Android device and I should be able to access that from another device also. The architecture is shown in below image.
Can we do something like this in android?
So I have two ways to do that:
Conver your csv file to db or sqlite using SQLite Database Browser and than paste this file into your assets folder of your project and than on create of your Application or Activity write it in the Data folder/directory of your app property and so that you can get your Database on each device.
If it does not help follow this one:

How can I view the DB in IntelliJ to view its content and perform operations on it. Now I have created my tables etc but i have no idea what data is on the DB and I do not want to create queries in java to check it. seems like a slow workflow so ill wait til I know how to access the db that resides on the Android emulator im using.
Is it possible?
You can also use Stetho. A nice debugging tool from Facebook.
Just simple to use, initialize it in your Application class and access your sqlite and even shared preferences from Google Chrome's developer console.
You can create a database file outside of Android and use any tool to create and read it.
Then, you place it in the assets folder and setup your code to read the database from there instead of private app data. Caveat here is that a copy will be made from the assets folder to the app data, so any updates within the app won't be mirrored to the database file in the assets folder.
I believe you can access the DDMS window in Intellij/Android Studio and there is a Database Explorer there
see #alexsimo's answer.
Without root you cannot access your database on your device, unless the file is created with a+r permissions.
Since that is something that is unrelated to the issue, you can just search in plugin.jetbrains.com for sqlite and get a variety of plugins.
For testing, I wanted to manipulate the sqlite database for my Android app. I copied the database file to my laptop, edited the file with the Sqlite manager plugin for Firefox, and copied the file back to its directory.
I thought that would work, but the app crashes, because it can't open the database. The ownership and permissions of the file is like before.
Can someone explain to me why it won't work, or suggest how I could do instead?
1.Use Sqlite browser..download here
2.Pull your database to your computer..
3.Edit the database using sqlite browser
4.Delete the database from eclipse then push the edited database to your aplication Run the app to see the result
I'm writing my first serious Android App, which basically is interface to three DB tables.
Data in those tables are predefined by me, so, user should install those app with those data.
What is the best way to include those data in application package? Maybe there is a way to embed SQLite into my application distribution?
Or is the only way is to define array of "insert into" strings somewhere in class and execute them to fill internal SQLite storage?
Would appreciate any recommendations.
I am currently doing the same thing in my app. Having a sqlite database file in my assets folder and copying it into the SD card at startup if it's not in there. There's a nice tutorial there and I use part of its code.
Put the database file in your assets and then copy it over to your application's data directory.

I am having Registration screen as my first screen but before that i want to create database. is it possible to create database at time of installation in android rather than creating in first activity.
This is a great article that helps http://www.reigndesign.com/blog/using-your-own-sqlite-database-in-android-applications/
Create the sqlite db using SQLite Database Browser and store it in your assests folder
When app launches, copy the db from assets to your apps data directory
Open the DB
This way you don't have to parse csv files or dynamically create the db on the device, saving time during first load.
If you want to use a previously created database in your application,at the time of installation the you need to create a database put it in assets folder and then copy it in application.
