I am not creating any database in android. We just copy and paste the database from assets:
getmyapplicationContext.getAssets().open(DB_NAME);
How we can integrate ORMLite with our App?
It's no difference if you're creating database with ORMLite or use existing one. Moreover usually you create it only once, and then work on existing one.
So you should probably use:

HelloAndroid example presents how your Activity should looks like
and create ORM schema classes that correspond to all your database tables.
There you can also configure correct path to your existing database file.
Good luck ;)

My project has some initializes data so I have already create a sqlite database with navicat application. I use kotlin instead of java and use room ORM too (android-architecture-components).
how can i copy my database too my project from asset folder without any problem?
referring to this question , you have just make sure of having same db schema in order to do that. and to copy file to /database folder in internal app storage there is plenty of resources and example just search.
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 am making an Android version of an iOS app that I already have. I want to use a local database so that the user can use most the app offline.
Initally I thought I could use the sqlite database created by Core Data in Xcode, but as I am reading things online it seems like this is not possible. Is this true? Or is there a good way to export it to something Android could use?
If not, I want to create a local database with values from a database on the cloud(I use Parse.com). How can I do this? The data on the cloud doesn't change very often (maybe twice or thrice a year) if that makes any difference.
This is a good tutorial to handle preloaded databases:
http://www.reigndesign.com/blog/using-your-own-sqlite-database-in-android-applications/
Essentially, once you have your precreated database, put it in your assets directory in your apk. Then on first app use, copy this from assets to "/data/data/YOUR_PACKAGE/databases/" directory.
You have to create the database by code in Android, using a DatabaseHelper http://developer.android.com/guide/topics/data/data-storage.html#db. If you want to use your already created database you will have to export it to SQL statements and then "import" them to your application.
I am developing an app in android which consists of activities that need to connect to the Database. I am having an existing sqlite DB with me. But I don't know how to include it in my project. This might be a very basic question, but as I am a newbie, I am finding it quite complex to get it working. Any help would be appreciated.
The easiest solution, by far, is to use SQLiteAssetHelper. You add one JAR to your project, package your database in a ZIP file in a specified location in your project's assets/ directory, then use SQLiteAssetHelper to access your database (much like you would use SQLiteOpenHelper).

I am creating a sample application using sqlite database unfortunately I am not familiar in sqlite database concepts. I have the following requirements,
I have a sqlite database named as quotes.db. The database having two fields in is number and Quotes. Which is stored in assets folder.
In my Activity i have two fields one is edittext and another one is button.
When the user enter the value (number) in edittext and click the button. Now I display the corresponding quotes which is stored in database.
if any one having sample code snippet similar to this kindly post. Thanks in advance.
You can follow this tutorial which is an introduction to Android apps and especially to databases in Android.
Quting the website:
This tutorial on writing a notepad application gives you a "hands-on"
introduction to the Android framework and the tools you use to build
applications on it. Starting from a preconfigured project file, it
guides you through the process of developing a simple notepad
application and provides concrete examples of how to set up the
project, develop the application logic and user interface, and then
compile and run the application.
There are a couple of ways of creating and accessing a database in android.
Method 1: Use simple SQL statements
For that follow this tutorial: http://saigeethamn.blogspot.in/2009/10/android-developer-tutorial-part-12.html
Method 2: Use a class that extends SQLiteOpenHelper
For that follow this tutorial: http://www.reigndesign.com/blog/using-your-own-sqlite-database-in-android-applications/
I would recommend you to follow method 2 as that makes it much simpler to query and update your database once it is all set up. Also note that when you move on to 'Content Providers' method 2 will again be very very helpful.
The Android dev manual has a useful introduction to the process. Take a look at the Searchable Dictionary for some example code.
