I have created my database in NAVICAT FOR SQLITE, now i want that database to be connected with my android Application.
I have surfed many webs but didn't found anything as a solution to my problem.
i don't know what will be the exact code for it?
However an additional feature i have to overcome is to handle some events like, if I update something in my Application, it should also be updated in my database which is currently in my desktop application.
I think it needs a WiFi connection for it?
Can some one guide me regarding this?
there's two options for ur problem..
keep that database in assets folder and after starting the application copy the db from assets into application package.. refer this http://iamvijayakumar.blogspot.in/.../copy-sqlite...
keep that database on ur internal storage or sd card.. and give the full path as database name.. it will work...
Recommended: use 1st option..

How can I view the DB in IntelliJ to view its content and perform operations on it. Now I have created my tables etc but i have no idea what data is on the DB and I do not want to create queries in java to check it. seems like a slow workflow so ill wait til I know how to access the db that resides on the Android emulator im using.
Is it possible?
You can also use Stetho. A nice debugging tool from Facebook.
Just simple to use, initialize it in your Application class and access your sqlite and even shared preferences from Google Chrome's developer console.
You can create a database file outside of Android and use any tool to create and read it.
Then, you place it in the assets folder and setup your code to read the database from there instead of private app data. Caveat here is that a copy will be made from the assets folder to the app data, so any updates within the app won't be mirrored to the database file in the assets folder.
I believe you can access the DDMS window in Intellij/Android Studio and there is a Database Explorer there
see #alexsimo's answer.
Without root you cannot access your database on your device, unless the file is created with a+r permissions.
Since that is something that is unrelated to the issue, you can just search in plugin.jetbrains.com for sqlite and get a variety of plugins.
I am developing an app in android which consists of activities that need to connect to the Database . I added my database file in assets folder which gets copied over to applications database directory on first time the app runs but "assets" directory and "data" directory(on rooted devices) can be accessed by any other application . I'm confusing between using database file or create database in code . If i create database in code it make the database file disappear in the "assets" folder . When users change the file extension from .apk to .zip ,database file will not appear in assest folder . What I should to do ?
Please give me some advice !
Both ways are good and useful it completely depends on your need.
By creating database in code you can secure your data from other applications but it will take so much pain to create it in that way so i suggest you to use a db or sqlite file in assets folder and while copying database on device or data folder use some security parameters to encrypt it or you can hide your app database folder on device so other applications and users will be not able to access it easily.
Well keeping Database in assets folder is not at all a bad practice plus it saves coding of creating a database , as far as you want to make it secure you have to do 2 things
1.keep you database in assests folder , and copy and save it in the internal memory , now its available only to your application and delete it from assests folder .
2.Use Proguard to protect it from somebody decompiling your application and obtaining the assests.
And yea if its a confidential data in the application and your application is worth it then you can also go for "encrypting data" but yea its a TDS task , see for yourself what suits you now.
Honestly, this is the best explained and a very complete tutorial on the subject
SQLite Android Tutorial
Don't get repulsive, because it's a bit longer one. Everything is explained nicely and you don't have to do the thinking about the location of your asset folder on different devices and so on...
I have a question regarding creating an android application for travel guide. I am creating it offline. I am familiar with the problem that we access the database on the real device. I want an external database file in which the data is already filled. I just want to include this database in my apk and just want to access that database in my phone offline. I am using SLQite database. I had imported db file from assets folder. It works on emulator but not on a real device due to no access to system files.
I think this blog post does what you want to do. I am using this approach in my applications for a while and I am satisfied with it.
It is fast and relatively easy.

I have included the db in assets folder and the db file is copied in the path sdcard/Android/data/packagename/test.db on a real device..now I am accessing the db, it works fine on emulator but when I used it on a real device it get crashed.the db is still not working on real device.
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'm writing my first serious Android App, which basically is interface to three DB tables.
Data in those tables are predefined by me, so, user should install those app with those data.
What is the best way to include those data in application package? Maybe there is a way to embed SQLite into my application distribution?
Or is the only way is to define array of "insert into" strings somewhere in class and execute them to fill internal SQLite storage?
Would appreciate any recommendations.
I am currently doing the same thing in my app. Having a sqlite database file in my assets folder and copying it into the SD card at startup if it's not in there. There's a nice tutorial there and I use part of its code.
Put the database file in your assets and then copy it over to your application's data directory.
