I have a database in my sqlite Manager in that i have one table.
Now i want to access that table through my android code.
Is there any possible way to do that...
Please reply me....
There is a bit of extra work involved but it can be done to include modifying your primary key and changing some of your db structure.
This article talks you through all the steps in depth.

It might actually be easier to just create a new db and populate it.

I have created a database in SQLiteStudio. The database consists of a single table, with columns 'Name', 'Age' and 'Occupation', and several rows of data.
I want to transfer that database from SQLiteStudio to an Android phone. How would I do this?
Well, the simplest way if there are only a few rows would probably be to create the schema and populate it in SQLiteOpenHelper.onCreate(db) using SQL statements executed with db.execSQL().
If you would like to avoid that however, and just directly take the database that you've created externally over into your app, you could look into Android SQLiteAssetHelper
Yes, the Android SQLiteAssetHelper is really simple compared to other guides that uses hundred of lines with codes. Tried numerous guide and tutorials before I found out about that helper. Here is a really simple guide to follow where he's using it and explains it pretty good.
Import and use external database in Android
I wonder whether there is a way to store data in like a MySQL inside of Android OS.
I have more complex data that I need to save and I dont think SharedPreferences will work.
Is there a predefined way, and how can I access it? Is it in SQL?
Of course there is. On Android each application has own place for database (SQLite). Read http://developer.android.com/reference/android/database/sqlite/SQLiteOpenHelper.html
for further details. It's really easy to maintain
Yep, there is SQLite
Here is a question asking for examples.
Here is the SQLiteDatabase class. Goo start point.
well there is SQLite database which is very light weight database to store data in android..
Edit
when you start working with SQLite on android you should not mix it up with MySQL or PHPMyAdmin or any other complex database structure. SQLite is just about storing some information on your device internally and accessing it for some purpose. It is not used for complex database tasks that you do in PhpMyAdmin.
Rather you should visit the links given by #Vee in the answer.
I'm working on an android project that requires writing to a created database and later reading from it.
The idea is for the user to fill out a form and then submit, it will submit into a database table in the first row. Then if they hit submit again it will submit to the second row.
I have all of the activity layouts defined but I'm confused on how to make the databases. I'm thinking maybe I can make a content provider?
Can anyone advise me on what to do? All of the questions I look at on here skip the baby steps, and that's what I need
Yes you should make a content provider. There are a lot of great tutorials out there for making databases - try section 8.0 of this one
http://www.vogella.com/articles/AndroidSQLite/article.html
Since you plan to use a pre-loaded (created) database wherein the DB structure has been already defined, Refer to this link on how to include your pre-created DB file into your app :
http://www.reigndesign.com/blog/using-your-own-sqlite-database-in-android-applications/
And to then add new data to your database refer to this tut.. You can ignore the create Table part here since you already have the table structure ready.

Hope this helps.
First of all you dont need Content provider...Content provider is only need when you want to provide your data to other application...Its kind of central repository of data for other applications.
Now You have to use the SQLITE database in android...Since android support sqlite database..
Below link will guide you...
http://developer.android.com/training/basics/data-storage/databases.html
Google has large manuals for all the aspects of Android development http://developer.android.com/training/basics/data-storage/databases.html
it might be done without content providers too.
this might be helpful.

I'm currently trying to learn how to use a SQLite database with android. I've managed to successfully follow http://www.androidhive.info/2011/11/android-sqlite-database-tutorial/ but I'm now looking to make a table with 25-30 fields. It seems like it would be a huge task to type out all this in a similar style to that link especially as I'd want to be able to search by many of those fields.
Is there something I can use to automatically generate a database helper class with this number of fields and methods to search them? Or am I going about this completely the wrong way?
Thanks
First off i just recently started android programming also and i particularly enjoyed this tutorial about databases : http://www.vogella.de/articles/AndroidSQLite/article.html
To generate the queries i think it will be better you use an SQLite Database Manager and just copy and past your queries in the methods.
Okay, so I am still learning to do some coding here, and I seem to have gotten stuck.
I want to have a select number of documents added to a package for the Android OS
but I don't know how to store said documents. Do I add them all under res/raw, or make an SQLite database and call from there?
More importantly, I need to be able to call those documents when a search criteria is added.
I was on the Android reference site, and they add write functions for the SQLite db, which I would prefer not having as an option.
What kind of database should I implement here?
I would prefer a link to an example, but anything would help at this point.
Try reading this.
Notepad example
or make an SQLlite database and call from there?
No you don't create a SQLlite database it will be created for you after your App start the database call.
See this SQLiteOpenHelper
And SQLiteDatabase
