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.

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 opened a SQLite database in my project. To see if the db was actually created I went to Data/Data to find the package name... not there. While testing I would like the ability to delet the file.
So I added data to the db, then read it out. This works fine, but still no file at either /Data/Data, or at /Android/Data/Data. Is the file hidden? Other dowloaded aps have data at /Data/Data/package/... but not the one I wrote. It does exist - I can read and write to/from it, but cannot find it.
//data/data/Your-Application-Package-Name/databases/your-database-name NOT THERE
Using a Samsung Galaxy Nexus for testing, not the emulator. The Nexus does not have external SD memory card.
SQLite databases are only accessible to the creating project, but is there a tool that can access it externally? I have sqlitebrowser (awsome) i will try if I can find the file.
I would try to Root the Nexus, but I can already see /Data/Data/ other items/Data/their data, so hopefully I do not have to go that route.
You're not able to access any contents of /data/data if you access it from adb shell without first rooting the device. Shell is considered as another app (more precisely another linux user), so it's prevented from accessing other app's data in /data/data.
Root the device or use emulator to see the data.
Personally I really recommend rooting the device for development.
ALL,
I wrote a simple android app that uses database.
When I execute it everything is OK. However when I switch the phone to mount mode I can't find the actual *.db file.
I am trying to execute following:
cd /media/
find . -name *.db
I also tried to search for the database file without success.
After playing a little with SQLite database browser I know that I need to save the file after creation.
Is there such a function in Android API?
Thank you.
If your app uses a database, it will be placed in the /data/data/<your-apps-package-name>/databases directory on your phone. To see it on the phone, I believe you need root privileges.
You should be able to pull the database locally to a connected machine which has adb installed on it. Or you can use ddms with Eclipse to pull the data to your machine.
I have created an android application for my Android device which stores records into sqlite databases and even the retrieval of the data from the database works correctly on my application. Now i want to access the database file located in the location as follows:
/data/data/org.project.compdroid.dash1/databases/data
where data is my database file.
This data file i want to export to my pc to keep a backup of all the records.
for this I first tried accessing it from the emulator by the command
adb pull /data/data/org.project.compdroid.dash1/databases/data [local address path]
this worked correctly for the emulator. but when i try to copy the same file from my Android phone it says permission denied. I think since I am not the root user for my phone I am not allowed to access it and I am allowed to achieve it in my emulator since I am already rooted there.
Now is there a way by which i will be able to copy the data file from my android phone without rooting it? or is rooting the only solution for my problem?
Please do suggest any other technique(if there are any) for copying the database files from an android phone to my computer.
Thanks in advance...
You can include code in your app that will copy the file from internal storage onto the sd card, since your App has full access to its own storage. See How to backup database to SD and Backing up your Android..
You could also spit out the Db as a text file which can then be imported into any DB.
i have created a db in the phone and have inserted some values in it as well. now there is a large excel sheet which contains several more records that need to be inserted.
i am trying to find the db file in the phone so as to use sql lite db tool to upload some data in it. but the folder is empty.
can any one suggest or guide.
thanks
If you are on a real phone the /data folder will appear empty unless you have root access. An application like root explorer can allow you access to these folders (with the proper permissions). This probably isn't what you want to/should do.
If you are on an emulator you can use the file explorer in eclipse to browse your phones data/data/package folders and copy your database to and from the emulator quickly (or use adb shell commands).
Are you just doing this to test something? You should have your application insert the data you want, or create your own SQLite database and package it with your application. If you externally modify your database like this, reinstalling the application - or installing it on a different device - would result in an application still using your old/unmodified database.
