I'm making a native android app with has some user data that I want to be stored in a database.
I'm planning to use Heroku to host it. The app should be able to retrieve it and overwrite it.
Right now, I am very confused as to how to start working on it.
There are three parts:
1)writing the actual database: right now I'm using SQlite database browser. I have created a simple table database. I have no clue how to deploy this to Heroku...
2)writing a REST API to communicate with android app on device: I gather that I should also deploy this to Heroku?
3)Connecting with the device: ??? I have no clue how this works... do I write a REST API in my native android app too?
Very confused! thanks for reading.
You should follow these steps as per my knowledge:
The database that you create should be for the device(the one that you have created using sqlitebrowser.
Create a separate database at the server side and create an api that'll perform CRUD operations using an xml or json file to reflect the data in it in the database at server
whatever operations you perform you can do them in the local database and later after checking the internet connection write the edited valueds in xml or json format and send it to your server where it'll be synced with the server database.

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 want to connect my Android Application to SQL Server database to check login credentials and then loading that data in GridView.
But now i don't know how to work with calling or executing the SQL-Server stored procedures in android application. Can you please help me in executing Stored Procedures from Android Application?
If you want to use stored procedure in SQLite, you can't. SQLite does not support stored procedures. Neither in Android, nor in other environments.
If you want to call external SQL-server, you can use JDBC.
Is it possible to connect to a mysql database using android service and asynctask without using any server site scripts such as php??
My application needs to create an offline replica database, and synchronize if updated by user.
Please give suggestion and possible links, references or code.
Thanks in advance.
be aware of this :
if you connect to a remote DataBase without using a webService you will store the database login credentials inside your app. so it'll be easy to extract your login for that database and access and edit it even destroy it by decompiling your app.
I've created a pre-made database in SQLite for an Android app I'm developing. The app should interact and pull data from the database and display it on different 'Intents'. For now I just want to set up a local server on my Windows Computer for the database.
I was wondering what is the best way of doing so? I have little to no experience with setting up local servers or anything with regards to servers.
Thanks for any help!
There is no such thing as an SQLite "server". SQLite runs locally only through libraries. Also, Android database connections can not simply connect to anything on a server.
If you need a database on a server and an Android client to manipulate the data, you need to implement some kind of client-server architecture, for example using (RESTful) WEB services or any other client-server-communication.
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.
