Previously, my application did not connected to AWS Database. I want to change database connection to AWS Database. But i found some trouble. I think it was same like we connect AWS Database into a Website Application. But it really different.
Mobile apps usually don't connect to a database directly but do crud operations through an api like a webservice.
So just create web_services and get data like normal https request in android app then handle received data with android apps logic

I wand to access the postgreSQL database from android using Pydroid3 application in my mobile phone. to access postgreSQL database i need to import psycopg2, but android doesn't support this.
can anyone please suggest the way to solve this issue.
With Android you typically don't make a hard database connection, unless its a local one.
psycopg2 doesn't work for the same reason you're not supposed to use JDBC . You should talk to a remote database via a RESTful API, meaning a server sends you data that it itself retrieves from the database.
So your next step would to create a web site/service that handles GET requests. So your app can talk to it, and it can talk to the database.
I am making an app which requires a database, so I want to use PostgreSQL from Google Cloud Platform, I did not find any tutorials helping me to do that, How to access the data? a link at Can i use PostgreSQL or mySQL in android App development
no longer works or outdated, found the REST API documentation for Cloud SQL but unable to understand if these APIs are just to access DATABASE or the data inside DATABASE?
As mentioned in the accepted answer to the post suggested by #JGH, there are a few ways to access data of a DB from an Android App.
The most commonly used way is definitely by communicating to a service hosted on a server that can connect to the DB, and provides endpoints to request any operation (read, write, update, delete).
However, since you specified a direct connection from the Android App to the Cloud SQL instance, the best option would be to try to make it work with the JDBC connecting to, possibly, a public IP of the Cloud SQL instance. You may find more information in the Connecting to Cloud SQL from external applications documentation.
So far I think it's a security thing that you're not allowed reading/writing to an Android SQLite database outside of the containing app's process.
But are there advanced techniques or tools that can be used to achieve this?
For instance, I want to make a web interface with a textbox where the Android app would connect to and then I can run SQL queries via said interface to read the database or to insert records into it.
I'm writing this question because I'm really stumped. Usually my search gives opposite results which is accessing a remote database with an Android app.
You will have to develop an API backend. The mobile app ( client ) will communicate with the API and do the desired operation based on the response.
It's not possible to directly connect to the app sqlite database. You can send web request and get the info you want, handle it in your app to store it in the sqlite database
You will have to add security measures, so everyone can't access your API.

Apps can read and write to their SQLite databases. Otherwise, the database would not exist.

You are certainly welcome to embed a Web server into your app. For example, Stetho does this to integrate with Chrome Dev Tools, offering your SQL interface among other things.
However:
Doing this for anything other than a debug build of your app is very risky, as securing a Web server is difficult enough when it is on a traditional server environment, let alone an Android device
The Web server is only accessible by whatever can reach the device via an IP address, which means it's usually only useful on WiFi (where it could be reached by other devices on the same WiFi LAN segment)
I want to develop a mobile application (android app) for my company web application. So , it will use the same database with the web database. My company use mysql google cloud. How can i connect my mobile application with the database ?
Actually ran into the same scenario recently. What i did was went ahead and looked into how to specifically connect your android application to phpmyadmin, which is a database that can connect android to your web sites database. Not sure who your web host is but i have a site that is hosted by Hostgator and they implement phpmyadmin in order for the webmaster to go ahead and handle the database. For more info i have posted this link which will guide you on the proper steps to take to connect phpmyadmin to your android application.

Hope this helps. :)
Create api interface in backend (php, etc...) through web to access database.
Use httpconnection to connect web interface and upload/download data by parameters.
I'm trying to create a login system for an android app and I would like to know if creating a Sqlite database solution would work across different devices. For example if I register in a device, could I access the app from another device with that same account without having to register again? If that does not work, what would be the solution? Thanks for the help :)
Ideal solution would be to connect the app to the server for authentication and authorization. The server can be build using any type of database whether it is sqlite or mysql etc. So it does not make any difference.
You can create a web service for the purpose of authentication using php, java or .net (your choice) and the android application can use any web service client framework such as service stack etc. for connecting to the web service.
What kind of authentication and other features you want will depend solely on your application design.
The best option is using a web server. I am doing the same and am using a .net web services for users authentication
For allowing same user to loggin in different devices with same credentials in the app you need to use central database .
Below is the link which will help you a lot.

Note : Sqlite database is the local database , we can not use it for our central purpose or out of the specific device.
