I created a MySQL database in PHPMyAdmin using the free hosting of 000webhost. I want to get the data in my flutter application in a Listview. I'm just wondering if I can do that without using any API. Does flutter allow getting data from an internet server without using API?
I guess it is not possible, since you need some sort of logic to handle what you want to take from database, and what you want to add into it, or other parts of CRUD. And that will be your API. I would recommend to take a look at some REST API tutorials, where you can build simple interface to send data to your flutter app or other applications. Try this for example.

This is just a information question. I'm new to Android app development and currently I'm working on my first app and and it is ready for the release. Now I'm concerned about how to handle heap of users and where to save all their details my app is a service booking app so it needs to save all the order details products details and lots other stuff.
Currently I'm using cloud firestore to load and save all the data of app. But I'm having some issues like without authentication it won't allow users to access some of my data and other. I wonder how large apps save their data and load them perfectly.
I wish someone will help me how can I save all my app data and load them perfectly in app. And suggest me for a best way to manage large user base. And other stuff.
First of all, firestore is good option if you don't have complex backend logic on the database. For simple CRUD operations on data firestore is a good choice but as you said you have a bulk of data then you must go for the Backend database and then connect your database with Rest API. So that all your complex queries will be done on the backend and you can simply consume your API in the app.
If you have lots of data from different users, maybe you should use a central server(DB), something like Postgres or MySQL should work fine.
At the same time, you can also do some sort of caching to accelerate the fetching process, like create a small database locally(you can use Room) to store some user specific data.
Hey guys I am new to android development I just created an app for android using back4app parse database where data stored in classes hope you are familiar with that and now I want to use the same data for my website using the same parse database please help me and suggest me something good to do this
parse-server store your data in a MongoDB database means that after the data is being stored you can access it from any device at any location. In your case you can start with a Web app, read, create, update and delete data and then you can just create an android app and use the same API's there and you will see exactly the same data that you see in your web app (if the logic is the same of course).
The best way to get started is with parse Javascript SDK for your web app and parse android SDK for your android app.
Later, you can create it for iOS or any other platform that you like. If for some reason you don't have the relevant SDK for your technology you can always use parse-server REST api's
If you need more info or have specific issue please let me know.
I am making an android project which inserts information into mysql database via php code. I am able to do so on my local server (using xampp). I have taken a free webhosting byethost7.com domain http://hpisys.byethost7.com for using my database and php file from that server. I am able to open php page on internet and insert the information into the online database server. But via android app I am not able to insert information using the same php code. Please help me out of this.
If you are also using this data in a web project I would set up a RESTful service and get the data that way. If not I would use something like Firebase instead, as it will be much easier to set up.
Either way you will need to research those yourself. You should be able to find a lot of tutorials.
I am developing an android dashboard app to display various charts.
I am having a local SQLLitedatabase in my application which contains all the values to be displayed.
But I want that whenever my app loads my db should get refreshed by hitting a web server if data connection is ON or else it should display the charts with the local db in offline mode.
Can I update my db using the JSON parser provided by the Android API?
Please suggest the best protocol for this
Yes you can do that. For network related queries you can use the Volley library. That will be good try that one.
clicke here for Tutorial how to use the Volley.
i want to create an android application but i don't know how to use the sqlite database i already have.
In fact, i have an existing sqlite database using by an existing software application for computer. The database is stored on a server.
I want to know how i can read the database stored on the server to be always up to date when using the android application ?
I don't know if i'm clear, my english is not really good and i tryed my best to explain.
You can imagine that like a restaurant. The main application is already created but i want to develop an android application and each server has an android tablet with the application so they can access to the database when they have to.
Thank you.
you have to have the following:
Call Webservice from your android app.
the Webservice has all methods and functions that you need to interact with database on database Server.
the Webservice must return the data you need from the database server back to your android app.
Here is a good tutorial that you can start with to get clear idea in how can you use Webservice with android apps.
