For testing, I wanted to manipulate the sqlite database for my Android app. I copied the database file to my laptop, edited the file with the Sqlite manager plugin for Firefox, and copied the file back to its directory.
I thought that would work, but the app crashes, because it can't open the database. The ownership and permissions of the file is like before.
Can someone explain to me why it won't work, or suggest how I could do instead?
1.Use Sqlite browser..download here
2.Pull your database to your computer..
3.Edit the database using sqlite browser
4.Delete the database from eclipse then push the edited database to your aplication Run the app to see the result

I have accessed my sqlite file under data/data//databases/. Then I tried to open it in Android Studio. I selected SQL File as the file type, but Android Studio showed me a sequence of characters. Not a browser of sqlite file.
Is there any way to fix this? Can I open that sqlite database file under an application like 'DB Browser for SQLite', without saving that file under a folder and opening it from there?
No, you can't open sqlite files in Android Studio yet. Every day I do it this way:
stetho (http://facebook.github.io/stetho/) - powerful tool which allows browse tables and execute queries
or downloading DB file into my local file system (through adb or Device File Explorer) and open with SQLite Browser (https://sqlitebrowser.org/)
Please take a look at SQLite Administrator. It is a free software, you can open a database file, create tables, launch queries, etc. I use it quite often when I need to take a closer look at a SQLite db file.

I want to use my own sqlite3 database in my android project.
I created this database with command-shell line (windows) and exported it with SQLite Database Browser (sql format).
I followed this tutorial and my database can't be open :
go here to see since i can't post image
My package is org.opencv.samples and my DBName is "maif" placed in /assets directory.
So it seems that my exported database is incorrect, can someone helps me ?
I suggest to use this helper to solve your problems: https://github.com/jgilfelt/android-sqlite-asset-helper
I don't believe you can transfer an external database through the file system to Android unless you have a rooted phone. If you have to transfer data you need to use data transfer via HTTP using XML/JSON.
In my android application, I am copying the sqlite database file to "data/data/com.mypackage/databases" at runtime.
I am using ormlite for database operations, but I'm not able to perform any databse operation (e.g. insert, retrieve, delete) because it is not getting any tables from the sqlite file.
However, when I copy that file in my SDCard everything works fine. I have verified that the file gets really copied in "data/data/com.mypackage/databases", which is the case.
Does anybody have any idea about how to read sqlite file stored in data/data directory using ormlite in android application?
select your file from data/data folder and pull the data base file in any location of your pc and simply open it with Firefox SQLite Manager
First of all if you want to read data/data folder from your device its not possible unless you r phone is rooted.
Second thing if you want to see the database in data/data of your emulator follow this:
go to DDMS Perspective.
select data/data/your package name/database/yourdatabsename
select that on the top you can find two options and one among them is pull you file.
save the file some where in your computer.
download sqlite browser by searching in google.
using the sqlite browser you can access your database.
hope it helps.
I created a app and added some tables, columns and some info in it and i want to check it, how do i do it?
Switch to DDMS perpective(Window > Open Perpective > DDMS).
Find out your database's db file in file explorer. Select it.
Export it by clicking on the button in the top right corner of the UI.(ie; Pull the file from from the device)
Use SQLiteman to view the data.
Hope it helps.
If you are running your app on the phone, you cant access your internal storage unless it is rooted. If that is your case simply run the app on a virtual device, then go to DDMS perspective, from there data/data/yourapplication/database/urdb.db then pull the db on the your computer and explore it with the tools stated above.
you can query the database from your android code to do this.
check the link http://codinglookseasy.blogspot.in/2012/08/sqlite-database.html where you can find creating table , inserting data into tables and retrieving it . Or use SQLite Database Browser http://sqlitebrowser.sourceforge.net/ to check the values without using the code
use Sqlite Database Browser tool to see the your Sqlite database.
Go to the DDMS and export your application database and open this database in Sqlite Database Browser
This post on how to access sqlite database on Android, will help you out. There is one mozilla plugin which can also help you to see the database.
I believe that Motodev Studio allows for database browsing.

Or you could just export the database to your desktop, for example, and then browse it with the Firefox SQLite plugin.
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.

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.
