I wrote an application in android which will sync with SQL-server database that is sitting on my Local Server.
i used web service to connect my apllication to my database and it works perfect in local. Now i want to test it in real device "Samsung" but it gives nothing !
Any suggestion please. Thank you
When you say Local Server, do you mean the database is on your development machine and NOT the phone? You are not using SQLLite for storing data? Usual practice is to use SQLLite (or any other data storing techniques like SharedPreferences or Files) in android but all the data is stored Locally on the device. If you need server side storage, then you need to provide an interface (for e.g. web service) that the phone can talk.

I am unable to figure out what is the best way to achieve a scenario like this:
Working on a project that would have android application as client.
User will take their device with the android application installed to field/visit and capture/punch/key data through out the day. This data would be stored locally on the device in SQLite database.
The data captured in SQLite needs to be exported out and imported into the desktop app (it could be java or .net based) for further processing.
Other points:
A. User could connect the phone via usb to desktop.
B. data flow would always be in one direction (i.e. Phone to Desktop).
C. No internet connection on the phone
My dilemma is how to access the sqllite database programmatically in desktop application? Are there any JDBC drivers that could read data from the sqlite database from a device connected via USB to the computer?
This is just a way to do what you want, there are more ways to do it but from my point of view is the most accurate and scalable.
You would have to make a webservices server on Java, PHP, etc ... with a database MySQL, MongoDB, etc ... and so the mobile device is synchronized with the database that was the cloud.
Thus after a desktop client would connect to the webservice to bring the data in order to process it on your desktop client.

I started developing an app that uses sqlite that is to be installed on multiple devices and any updates done on sqlite database from any device are to be reflected in other devices as well. I have researched a little and found that Sqlite DB is local to a device and changes done in one device are not reflected in others and for that I have to use external server. Is there any way around it?
Is it optimal to directly store data in external server or use sqlite and sync it regularly with external database?
Thanks in advance
As far as I know, there isn't a way without an external database. I would recommend you to sync it regularly with an external database.

Answer of Andrew White
Create a webservice (REST is probably best) and serialize your SQLite/MySQL data and PUT/POST/GET it to/from your web service. This will give you a nice layer of abstraction in case you decide to switch from MySQL to something else server side.
You will achieve your goal using external server. It's not necessary to create your own server, just use data store services like Parse. For more look here.
You can use data directly from external server or cache them on your device first (sqlite, prefs, json etc.) – it's up to you.
I'm new to android and I've created sample application that retrieve data from MySql DB (through PHP script) ..and its working fine on android simulator but my problem is when i tested the application on my mobile device there is no data retrieved !
I think this is because my DB on localhost so what is the correct way to retrieve data from my database to real device ? Is there specific IP should i use for this purpose ?
knowing that I've used WAMP server to create mysql database.
Any help is highly appreciated .
I think the easiest way is to host your database on a free database hosting site and connect to that.
You can try http://www.000webhost.com/free-mysql-hosting (Havent tried it but have heard it works)

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'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.

Good luck with your project.
