Develop Reference

I need to make an Android App which will retrieve data from a web database server, so what type of access (telnet, ftp etc) do i need?

I am a beginner in developing android apps, and I need to know which kind of access do I need in order to retrieve data from a web database server to an android app.

You can use Firebase from Google for better database support for your app. You can easily do that using Firebase Documentation.

Can i publish an app using sqlite instead of shared data like google volley?

Are there any specifics for the database or do I need to switch to Google volley and PHP for a shared storage option? or is there a way to publish using sqlite.
I want shared data usage for all app users.
I have an app I made on Android studio using sqlite and is there a way to publish the app without using Google Volley for shared data resources, zim new to this.

If you are going to use VOLLEY and PHP you have to implement and host the backend.
But you can simply use a service like firebase so you dont need to care about a centralized data store.
Another one is DREAMFACTORY where you can create API end points and can use MLAB (an online mongoDb server) as data store. Those are free and open source.

User Sign up and retrieval of all user data app in android with SQLite

I am a newbie in Android Development, I want to build an app where user from anywhere can register (Userdata should be save in sqlite db) and after registration n login process user can see all the other user list who are register.
Is this possible using android and sqlite db. I search many times on google but all i found tutorial for sqlite. I started to follow the tutorial but i am confuse as it is stated that Sqlite can only save APP data and private data of user. How could i make app for register user from anywhere. Suggestion and links for another method to do that is also helpful, Please Help
Thanks in Advance

SQLite can save only data for specific user in the specific device of the user. No one can access SQLite database which is stored in my device from any other device. Such scenario can be implemented by centralized system where all the details are stored in Mysql, mongo DB or similar. These databases are stored in centralized system so that it can be accessed from anywhere by anyone as per authorization settings. It is accessed by the internet.
So as per your requirement go for centralized system where database can be used by using web services. Web services can interact with server in which database is stored and can give you desired output in form of JSON or XML.

SQLite or Parse for android app?

I am an amateur app developer. I have developed many android apps but for offline use only. Now I'd like to make an online app. The users should login with Facebook account and I handled that. The problem is that I want to save some data like the user Facebook friend-list and some other stuff. I knew that there are 2 ways to solve such problem the first one is using Parse and the second one is using the SQL-lite so which of them should I use?

I think that the Parse database is more suitable in this case, because you will be able to sync the data automatically, when you store it in the cloud

Can you use the database on a website for android?

I'm developing an app and a website simultaneously. The website will be done in django and using Google' app engine, so therefore Google's database. IS there anyway i can download and use the database for an android app? Preferably I would like it to download and make it available offline to the users.

use a REST api like django tastypie on the server side, and consume the rest resources for the models you need with your android app. After you get the Json/xml messages on your android just save it to the local sqllite db

Android does provide a SQLite interface for you to read and write to a local db. You could fetch the db through a web request and save it locally, yes. Being on Google App Engine does not help / hinder your ability to do this.
