I am developping an Android apllication i wich i have an sqlite database which i want to extract the file (.db) to manage it with a manager (like sqlitemanager for example).
For that, i searched in many sites and the answer of the "how question" was the same, it consists of the following steps ( from http://forums.xamarin.com/discussion/4991/copy-sqlite-db-into-android-app ) :
1) Open the Android-sdk-windows
2) then open the tools
3) then ddms open
4) Dalvik Debug Monitor is open
5) then Device -> File Explorer.
6) data/data/your_project_package/files/your_database_file.db
7) copy your_database_file.db and open sqlite manager
I have followed these steps normally but my problem is that my data folder is empty !!, it does contain any another folder, and am getting this although i installed the application on the device, so i do not know what is the problem source.
I will be gratefull for any help
Thanks.
In the image below,Let if com.android.browser is the package name of your application then your database will be created in the db folder (not in the image ) as a sibling of lib.
Note: While working with sqlite database in android,I came to know that the created database will not show up even after the create statement for the tables are executed.They(the databases) are visible only in the DDMS file explorer, when some row is inserted in the table.So make sure you are performing some insertion before you start dealing with the database.

I've already followed the instructions in the top answer Here.
Using the device file explorer in Android Studio, I find my app's database. I then right click on the "databases" folder and click save as. I save it in a development folder elsewhere.
I have downloaded both DB Browser for SQLite and Sqliteman. Both of these programs cannot open the files from above.
When I "Open Database" in DB Browser for SQLite, it does not see the files in my file path.
When I open the files in Sqliteman, I get an error. This is true for all three files.
In my app, some fields in the database are working. When I try to display the data (in my app) the date and time stamps show up, but the text does not. I was hoping that I could look at the tables in my database to see if they're even being saved.
I'd love to see the tables in my database. What am I missing? Thanks!
I was able to figure it out. Here's what I did:
All three files just needed to be renamed to .db, .db-shm, and .db-wal respectively. DB Browser was able to open the files. Sqliteman still won't work. It's probably too old.
I am developing an application on Android where I need to use a database (SqLite). However, I don't know where it is saved and even if the database is really created... How can I ensure it?
Thanks
The SQLite database is by default stored at below path:
data/data/application_package_name/databases/your_db_file
However this path is private to the application and you cannot access it unless the device is rooted. You can have a look at this path when you run you application in emulator and then access above path using 'android device manager' from Android Studio.
Go to DDMS -> file explorer -> data -> data -> see your package name -> databases -> here your database file. (In the upper right, choose "Pull file" from device.) Export it and open through an Sqlite database connector.
It totally depends upon your code implementation. You can create Database in internal(that is app memory) or in external memory as well. Well in case of internal memory the database is not visible in directory structure while in external case you can see database file physically.
I implemented my first app using Xamarin Studio (Mono for Android). This app stores some data in a SQLite db, which works fine on a Sony Tablet S device.
My question is: is there a way to get db file and see, for example, its size?
I looked up to the following path
/data/data/My-Application-Package-Name/databases/My-database-name
but it doesn't seem to exist.
Thanks for any help!
You can use Eclipse to go right to it using the sqlite manager plug-in (http://www.coderzheaven.com/2011/04/18/sqlitemanager-plugin-for-eclipse/)
Download the *.jar file from the website I reference above to the
"dropins" folder in eclipse (open your eclipse folder and you should
see it)
Then restart eclipse and go to the DDMS. You may have to do
windows->views-ddms if it isn't already being displayed...
Select your device from the left panel then use the file explorer to go to your data
directory/YOURAPP/databases. Hopefully there will be an icon that
shows up when you select your database. If not, rename your database to use the "db" ext.
Click it and it should open in the manager tab.
This is a valid database location (//data/data/My-Application-Package-Name/databases/My-database-name), but you can access it from file managers if you have root access only.
Look how it can be done here. Otherwise, if you want to get some info trough the code, you're doing something wrong, so publish the code and logcat.
i am new in android database.i downloaded sqlite database browser.
can u give me the steps how to use already generated database in android sdk with eclips.
give me proper structure where to store database in eclips folder structure
When you create a database in your application, it is stored in
/data/data/com.zenika.droidcontact/databases/nameOfYourDatabase.db
You can find this file by going in the DDMS perspective in Eclipse, in the file explorer view, select the emulator and then, follow the path here above to your file. Then, select it and you can use the "Pull a file from device" to get this database on to your computer. Then you can start SQLite Database Browser. now you can open your file, modifiy it in the software, execute request with the 3rd tab, browse tables and data with the first and second. Then, you can save the database modified and push it back onto the emulator just the same way as you pulled it, but with the push button.
Is this clear or do you need more explanation?
How can I browse the SQLite database that I am creating in my app on my Android myTouch phone?
When I log in through adb shell, sqlite3 gives me a permission denied. Is there another way to check if my database and tables are actually being created, and if rows are being inserted?
I am not able to use the emulator, since it doesn't play videos etc. very well that is the main feature of my app, so I can only test on phone.
The entire database is a single file, so via the DDMS view in Eclipse or via the command line you can pull that file from the phone. You can then use SQLite DataBase Browser to view the contents, for example.
Using this library you can browse your SQLite database directly from your application

Its a single java activity file ,just add the java file to your source folder you can view the tables in your app database , update ,delete, insert rows to you table .Everything from your app.
When the development is done remove the java file from your src folder thats it .
It helped me a lot .Hope it helps you too .
