My proble is I created a device in sqlite database browser and its work fine in emulator.
but when a try my application to my device it cause force close.
and when I remove the database and create a new one using eclipse it works fine even in my device. But inserting a lot of data in database 1 by 1 realy freakin me out so anyone know a sqlite database browser that also work for device??!
check out this tutorial for using database file in application.
Remember one thing that it only copy you DB file in application that's it.
On real device you don't have permissions to sqlite database. That's why you won't be able to browse database like you can on a emulator.
See this for a work around.
Tool to see android database, tables and data
If you want to create a pre-loaded DB outside of your app and use it in your app later, you will have to put it in your assets directory and then copy it to your apps storage space the first time your app is started.
This is due to the fact that as a security measure, on real (unrooted) devices nothing but your own app is allowed access to that apps databases directory (and certain other ones as well).
There is a good tutorial for creating/copying your own DB outside of the app and copying it to the apps databases directory here.

I have a question regarding creating an android application for travel guide. I am creating it offline. I am familiar with the problem that we access the database on the real device. I want an external database file in which the data is already filled. I just want to include this database in my apk and just want to access that database in my phone offline. I am using SLQite database. I had imported db file from assets folder. It works on emulator but not on a real device due to no access to system files.
I think this blog post does what you want to do. I am using this approach in my applications for a while and I am satisfied with it.
It is fast and relatively easy.

I have included the db in assets folder and the db file is copied in the path sdcard/Android/data/packagename/test.db on a real device..now I am accessing the db, it works fine on emulator but when I used it on a real device it get crashed.the db is still not working on real device.
I have a app that has a database... So through DDMS i exported its database as .db so i want to know how do I open it to see its tables/values ? Is there a specific program that opens it ?
You can use any SQLite software, for example, SQLite Database Browser or SQLiteSpy. If you use FireFox, you can use SQLite Manager.
Also, if you have SSH-access to your rooted android device, you can use sqlite3 program from console and perform any SQL queries you want. By such way you do not need to copy database from device, and can debug what you need in real time.
I have a problem related to the app that I developed which runs on honeycomb. When I reinstall the apk its database gets deleted. There did not used to be this almost 1 week ago. Why this is happening now? What can cause db to be deleted and how to prevent it?
I think, If your database stored in application's internal storage /data/data/<package_name>/databases/ then when your application un-installed from device, all directories with your application package are removed from the device this cause your database removed.
To prevent put your database copy in application's /asset directory so whenever your application first time runt it copy the database from asset to internal storage path. And you can access it whenever application re-installed, also you can put your database in /sdcard but user can also delete it..

Thanks...
i guess it about checking existing database in your code. but i'm not sure exactly, it can occur from many causes. Just give an idea.
I could not find the sqlite db file of the application that I am developing runs on a tablet (not on emulator). Please anyone share with me that where does android keep db file of an application. And how do I export it to the computer? And finally is there any tool that can parse an sqlite expression even if it has no db or table? I mean it will only check the phrase and will say the phrase is available to run or not.
Unfortunately, application's database files are not available on non-rooted devices. You can either use a rooted Android device, or Android standard emulator, or Genymotion (see https://www.genymotion.com) in order to be able to access database files of your app.
It keeps it in a private embedded linux folder that's based on your application name, but that only the userid of your application can access.
There is no way for you to copy that file directly unless you root your tablet. In the emulator, that file is directly accessible, but the emulator is a special case.
That being said, there is a programmatic way to pull out the data from that database and reconstruct it on the SDcard to pull it back on your PC (that solution is not perfect, but at least it's better than nothing).
Nope, You can't access the DB of the device (eithr phone or Tablet) via ADB or any other third party Eclipse plug-in.
This was restricted because of security, but you can access it if you root your Tablet or Phone, which is again most people don't prefer to do.
or you can choose to make the db in sdcard (which recomended when the db is too huge).
I am designing an app in android, for my app i created one database for data storage now i want to browse my app database from device so that i can monitor my tables and it's data. I am able to browse the database from AVD(using SQLite Database Browser) but it's not working for the device, so pls guide me.
Thanks,
Balaram.
Balaram , currently there is no way to browse database on the device (the way you want it) (without getting the root permission) similar to browsing on a SQLite Database Browser
While to browse the database on the device you need to follow programmatic steps given here at 'Using your own SQLite database in Android applications'.
Hope it is helpful.
You need to root the phone and get SuperUser permission to access app databases. The database will (after getting root) then be available in the "/data/data/com.your.application/databases" folder. Also, after getting root on your phone, you will a file browser capable of using the SU permission to display system files. For e.g. Root Explorer.
What works in the AVD works exactly the same on the device. Ideally, there is no need to grab your DB from the device. But if you must, be careful with the other system files.
