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?

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 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 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 downloaded the jar file and placed it in /plugins directory. Restarted eclipse as asked for eclipse to load new plugin. Opened file explorer and navigated to /package.name/databases/file.db but not able to open it in the plugin. It appears unclickable. What to do here? Check screenshot.
From the emulator unistall the app.
Then in the code, when you create the database, name it with extension.
For e.g. if your database name is MyDB, then write it as MyDB.db
This will enable the Open File Icon on sqlite manager on eclipse.
As from your Screenshot it is clear that your database doesn't have an extension currently.
Therefore it is not allowing to open the database file but if you can see here
You can delete the database from here using the "-" option delete both the database and .journal file.
Add .db extension where you are creating the ordersManager database and run the application again.(Remeber to create the database)
when you will again come to DDMS to see your database and click on ordersManager.db file the icon which i have circled will become enabled then click on it and you will be able to read data.
Also you can pull the database from device and use something like SQLLiteBrowser
Here are thr few useful links :
1) Link 1
2) Link 2
The mistake that you are doing is that you didn't mention the ".db" extension with your db name. Delete your previous db and name a new db with .db extention i.e. "Sample.db" try it i hope it will solve your problem.
You have to mark the database like you did in your screenshot but then you have to click the database icon in the top
also its better to place the plugin in the dropin folder because you haven't loaded it by a url
Try this download SQLite3 manager from this http://sqlitemanager.en.softonic.com/ . And install it.And pull your database (i.e. file.db ) from DDMS to now location and try to open it with using Sqlite3 manager.
And you will be able to see your database contents.
I think this is what you want.
Try this..
Download the Android Sqlite Manager here.
Add it to your eclipse > dropins Directory.
Restart eclipse and go to DDMS.
Select .db file in DDMS Perspective
click Sqlite Manger icon.
Now you're able to open the .db file.
I am able to view the database from eclipse(from file explorer), but I want to view the whole detail, I mean the data that I have inserted, which I am unable. And my complete Android installation has made on F Drive.
You can access this folder using the DDMS for your Emulator. you can't access this location on a real device unless you have a rooted device.
You can view Table structure and Data in Eclipse. Here are the steps
Install SqliteManagerPlugin for Eclipse. Jump to step 5 if you already have it.
Download the *.jar file from here
Put the *.jar file into the folder eclipse/dropins/
Restart eclipse
In the top right of eclipse, click the DDMS icon
Select the proper emulator in the left panel
In the File Explorer tab on the main panel, go to /data/data/[YOUR.APP.NAMESPACE]/databases
Underneath the DDMS icon, there should be a new blue icon of a Database light up when you select your database. Click it and you will see a Questoid Sqlite Manager tab open up to view your data.
*Note: If the database doesn't light up, it may be because your database doesn't have a *.db file extension. Be sure your database is called [DATABASE_NAME].db
*Note: if you want to use a DB without .db-Extension:
Download this Questoid SqLiteBrowser: http://www.java2s.com/Code/JarDownload/com.questoid/com.questoid.sqlitebrowser_1.2.0.jar.zip
Unzip and put it into eclipse/dropins (not Plugins)
Check this for more information
Dowlnoad sqlite manager and install it from Here.Open the sqlite file using that browser.
Try this..
Download the Sqlite Manager jar file here.
Add it to your eclipse > dropins Directory.
Restart eclipse.
Launch the compatible emulator or device
Run your application.
Go to Window > Open Perspective > DDMS >
Choose the running device.
Go to File Explorer tab.
Select the directory called databases under your application's package.
Select the .db file under the database directory.
Then click Sqlite manager icon like this .
Now you're able to see the .db file.
I recommend the firefox plugin(SQLLite Manager) if you always use firefox.
Here is the link
If you are able to copy the actual SQLite database file to your desktop, you can use this tools to browse the data.
1. Download SQLite Manager
2. Go to your DDMS tab in Eclipse
3. Go to the File Explorer --> data --> data --> "Your Package Name" --> pull file from device 4. Open file in SQLite Manager.
5. View data.
Open DDMS than in DATA>DATA>"Select your package like com.example.foo"> than select your database folder than pull that data
in eclipse you can see the pull an push icon on top right side ...
If you don't want to download anything, you can use sqlite3 tool which is provided with adb :
Examining sqlite3 databases from a remote shell
and :
Command Line Shell For SQLite
