I make an application which cannot run in emulator. So I use android debugging mode or live running. It is running well on my device. and in that application, I create a database for user login. I want to see the data on my database. I mean I want get the database file, and access using a tools like sqlite manager to see the inside. the question is, how to get the database file?
Generally, if I using emulator, it places in data/data/com.package/databases/namedatabase(.db or without it).But when I connect my device in pc and running it, actually there are 3 directories, data, mnt, and system. When I was try to check the subdirectories of data, it is none. There is not any directory in it. so I can't get the database file.
I use eclipse.

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 about access to database. I have a database, but I can't see this database in data on my davice. On emulator in data I can see this database but on device data folder is empty. I need to do this because when I want to see database in DDMS perspectiv with emulator, my eclipse is stuck and I must restart.
Android doesn't provide access to its application data folders in a device. You can either root your device(which essentially means you give everyone access to all files in your device) or you could move the db to sdcard (if that is a possible option). You can access files in sdcard from adb.
You can access the database using ADB from the terminal (in android tools folder or platform folder). You can't access the database in the device unless you root your device. That's to restrict the application data from being open . (Other application's data).
I have been using an SQLite database in the application I am developing for the android platform. I would like to explore the data from my PC and see the tables and entities. I don't think I have the proper security to access it when I try from the DDMS file explorer on eclipse. I can't open the data folder and when I copy it on my desktop it is empty. Does anyone know how to dump my mobile android SQLite database onto my PC?
You could use cellObject sqlite browser to browse directly from DDMS below is a link to the eclipse plugin: http://www.cellobject.net/Tools/CellObjectSQLiteXMLBrowser.aspx
Without rooting your phone you can get a copy of the DB by running the app on the emulator and then use the DDMS to pull it.from there. It will be the same as if you pulled it off your phone.
You can get DB file your application. Even if your device not rooted.
You must add debug action: copy from \databases\database.db to sdcard. Get database path by getDatabasePath.
From sdcard you can get file by adb pull or File Explorer.
Also you can process back operation: copy from sdcard to app. Of couse you app at device don't
be started.
Иut I have not had any problems, even when the application is running, but there is no access to the base.
I am working with SQLite in an App. It writes to the database, etc., with no problem. However, I can not find this new database. I have tried changing the directory with cd /data/data/packageName/databases, but it says "no such file or directory". Also, this database is not found when I click on the File Explorer in eclipse. My logging tells me the database was created and that it is being written to. I think I need to set the path in the shell or something to that effect using adb, but I have no idea how to do that. Can anyone give me some instruction? Also, I am using my phone for development. The database also does not show up when using the emulator.
Thanks very much.

Matt,
This thread gives a good explanation on why you might not be able to access the data folder on your phone.
Can't access data folder in the File Explorer of DDMS using a Nexus One!
You can still test the Sqlite code though. Just boot up an emulator. The emulator will have no access restrictions. Once it's booted up you can use the ddms tool (located in the tools directory under your android SDK install folder). It has a File Explorer and you can download the files from the /data folder.
Also, I am using my phone for development.
You cannot access the database on a standard Android device except via your own application code.
Your options are:
Do this sort of testing on an emulator, in which case you can access the directory that you are failing to access on the device
Add a database backup feature to your app, that copies the (closed) database to external storage, so you can examine it
Root your phone (leastways, I am under the impression this can help get you to this directory -- haven't done it myself)
The database also does not show up when using the emulator.
Try harder. If you can store data in the database and read data out of it using SQLiteDatabase, then the database file is there.
Apps runs fine on emulator, but the same does not on device(Samsung S5670). Its showing that the database is empty.
Should i need to upload databases separately or it is embedded in apk itself.
I have also check the File explorer in DDMS -> "Data" section could not find any data in it.
Do i need to make any other setting on device
I guess you didn't write the required SQLite helper class that initializes your database. Somehow once you managed to create the correct database on the emulator, so it works on that. Try uninstalling your app completely from you emulator, reinstall it, and see if it works. Only updating you app doesn't remove data associated with it on the device, so i doesn't affect your database, hence you need to uninstall.
If it stops working on you emu too, then you need to go look into your SQLite helper class.
