I need to design an Android application that stores a database on a device and a copy of that database on a server. This application also needs the ability to query the information based on username, date, and three other parameters. What is the easiest way to go about this? I'm new to programming and any help would be appreciated.
To create Database in your Device you can use Sqlite.Refer Android Documentation for Storage.
Also create a copy of this database on your server and sync these Server Database and Local Database.
(Or) you can use Syncing to the Cloud google cloud storage and sync the local device database and cloud database.

I have an android application which uses SQLite database (stored in APK) for storing offline working data. The app is used only in offline mode.
Now I want to create iOS version and I want to implement idea of synced databases on both platforms - Change database on server and it will update databases in device when will be online
My first idea was to replace SQLite to Firebase Realtime database but there is a problem with offline mode. Is there a way to cache the whole JSON for offline use?
Or is it easier to use a cloud for storing SQLite database and implement syncing with new versions of the database?
Thank you for your responses.
The Firebase Realtime Database client automatically downloads the data at these locations and keeps it in sync even if the reference has no active listeners. You can turn synchronization back off with the following line of code.
DatabaseReference scoresRef = FirebaseDatabase.getInstance().getReference("scores");
scoresRef.keepSynced(true);
scoreRef.setPersistedEnabled();
But this need very first internet connection to sync, this will no enable data without that first request.
For detail about the offline capabilities, head out to the official doc link here.
I have software that connects to an SQL database. I am now working on the software on Android, using SQLite, and need to transfer the SQL database (with the data) to SQLite.
How can I do this?
One way would be to create the SQLite database on the device and download and persist the data into the local SQLite data base. A good place to read up on how to do this is in the Android docs.
Another possible solution would be to create the SQLite database at the server level and download it directly within the Android app then open it. But if you modify anything locally within the app you would need to send data back to the server to keep in sync.
Create Rest API that will fetch my SQL data in JSON format.
Now from android app access that API to get data and insert that data in in your SQLite.
or if you want to fetch it in background process use sync Adapter.
I am trying to develop an android app to get clients(Clients android device) current location and send it to the server (Admins Android Device).
I want to use SQLite DB for it,
How can I make database to be shared among various clients & a Admin.
There is no way to store database on online, you have use webservies to sync your current location to server.
I need your help on SQLite database development, We have an application existing with 3rd party database which help us to store collected measurement data using Android Tablet.
For example : Time of recording, Latitude , Longitude.
These should be recorded in mobile and tablet devices.
I tried to get database schema through the DDMS file explorer but I do not see any .db file.
Usually these are stored under data/data.
Our intention is to create own SQLite database and this will support to store huge data.
In above scenario, how should I get 3rd party database schema ?
I have tried, but it doesn't gave me successful result with emulator and SQLite manager ?
In general how do i access db in real device?
If your database supposed to store some huge data, you should set your database on a server and connect to it from your application on the android-device via internet.
For this you have to know How to connect to a SQLite database and config the server's firewall to have access to the database using your app.

I'm developing a web app with Java Servlets that can access an oracle database through the Tomcat server. I am also developing an android app that I want to use to be able to display the information that is stored on this database, so I will need to provide the user with the ability to log on and access the data from the database. The information will then also have GPS coordinates to display the items on a map.
Any ideas of the method or process involved in achieving something like this? Thank you!!
One really easy way to solve this problem involves using another product from Oracle, Database Mobile Server.
Having your Android devices connect to Oracle Database over the network has serious security and other implications.
Instead, you can just use the local SQLite database that is built into Android. Database Mobile Server provides a sync client that runs on each Android device, and synchronizes the local database with the remote Oracle Database in the background.
You can read more about the product and download an eval copy here:

Good luck with your project.
