I created a small application in JavaFX and deployed it in my Android device using Gluon Plugin. One of the requirements of my application is to store data in SqlLite database. I know how to do it using Android SDK but I dont have any idea on how to do it in JavaFX. Need help!
Download and add the SQLite JDBC to your classpath.
Following it, create a connection :
Class.forName("org.sqlite.JDBC");
connection = DriverManager.getConnection("jdbc:sqlite:somefilename.db");
You can replace somefilename.db with somefilelocation\somefilename.db, if you want to specify the location of the database file.
Then use the connection to create Statements and ResultSets to interact with the database. Everything is mentioned in the tutorial, #MadProgrammer just gave you.

How can I make an online database for an android app?
I am making an android app about the impressive speech and I want to make a database storing accounts of users so they can retrieve their progress anytime anywhere. But how can I make it online so it is accessible from every device?
You have to use a service such as Firebase or write a backend-server which runs a database (for example using Spring Boot and a simple H2 database would solve it).
the best solution for your problem is to use Firebase and especially Firebase Database.
Another solution is to use Parse Server.
My question is how to connect android with java,and Mysql? I am doing a project on android where i need to save the data given by the user in database. can anyone help me in this?
I would generally expect JDBC to work on Android against MySQL. I am sure you can find plenty of good examples there and make it work if this is really what you want. However there are a few things you want to make sure of before you go this route:
Is your app connecting directly to a database server?
Is that expected to be available through a firewall?
Are you sure you won't need something like connection pooling?
I could imagine cases where one might want to connect directly to a database server from Android but these are niche cases. Make sure it is what you want to do and then use the relevant JDBC driver if it is.
I'm using galaxy note with rooted software but I'm retying to find some way to test and manage and browse all my sqlite contents values and tables via eclipse
I have used com.questoid.sqlitebrowser_1.2.0.jar plugin but it give me disabled button in DDMS
note : I'm deploying my app on real device not emulator
I'm not sure if this gonna helps you. But, i had the same problem with questoid and the problem was that i tried to access a database file that wasn't closed by my application.
I also was using WAL Sqlite database. If you are using a WAL sqlite database and then you found 2 files with extension .shm and .wal, then your database file is not closed.
I have an Android app that uses a db4o database, and I would like to query this database while running my application. I have already installed OME (ObjectManager Enterprise) plugin on Eclipse, but I don't know how to connect it to my Android db4o database.
Has anyone been able to do this successfully? I'm not even sure if there is a way to access my Android app's data while the program is running.
I am afraid, there is no direct way to do this. You have to copy database from your android emulator to your machine and then query the db using OME

I am developing an app in Android. I would like to attach a database (created in C++) to my app Android that my Android app could read. In which format should I create this database with my C++ program?
Android provides a built in SQLite database, which is used by the applications developed for it. The Android SDK provides a well-defined, easy-to-use API to this database, and as long as you don't have a real special need for your own database, I would suggest using it.
You might want to have a look at sqlite (www.sqlite.org/).
sqlite - http://developer.android.com/guide/topics/data/data-storage.html
SqlLite is the built-in database. Portable across Android, iPhone, HTML5 and just about every embedded system.
I take it that your question is how to create a database on a host computer (using C++) and transfer it to the Android App. If so, then have your C++ program create a SqlLite database on your host computer and then either package the database with the app, or download it into the App's data folder from a server.
