I have a web application built on java and an android application. Both are deployed on different servers. How can i send request from android application to web application? Also, how can i send corresponding response from the web application to android application?
use REST api's (in JSON format).
This can be done with the help of web API's . You have to create webApi's on your server and, You can use AsyncTask in your android application to communicate with those web Api's.

I have created Login page in asp.net with MySQL and that web application published on IIS. I want to access that username and password using Web service in my android app. how to create web service for that and how to access it my app please help me.
WEB Api is a platform to create Restful services which can easily consumed by your android app, web application etc. Refer this link Create Restful services
Hi guys so I am new to android development or any mobile device development.
So I am working on a project that consists of two application.
One with ASP.NET MVC4, one with Android.
what it is doing right now, Android device is accessing database server of ASP.Net application and saves data. This is able because currently, android app has database access information in the codes(db login info).
Since method above is extremely stupid I need help.
So what I am looking into is to use JSON(if possible). ASP.NET MVC4 application is already JSON ready, and i've made sandbox application that brings information from web app to android app. BUT my question here is is it possible to do same thing the other way around. Is it possible to make android application to make JSON and web application to access that application? I dont think this is possible.
So how do other REAL mobile applications save users data on their database server without including db access information within the code?
This is usually done through web api - have a look at twitters api as an example https://dev.twitter.com/docs/api/1.1
You would have to pass data to the server using the api, just as you would use an api to get data from the server.
I was reading that SOAP is really not for Android. Rather Android prefers REST web services. So my question is, are there any other kinds of restrictions ? For example, some web services are built with JAXB. Is that ok for Android apps ?
I other words, does it matter how the REST web service is built ?
What if the web service returns data in XML format, is that ok with Android ?
It does not matter what kind of Webservice you are communicating with.
You communicate using HTTP protocol. If you use SOAP then you can parse your xml at client side.
Also there are many SOAP clients already available so you dont have to do much work.
Check this - http://code.google.com/p/ksoap2-android/
There is no restriction with REST web services on Android. Yes android can handle xml. You can get detail knowledge and help by going through GAE (Google app Engine). Find the link below:
https://developers.google.com/appengine/docs/
Android does not provide a built in SOAP client, there are many third party libraries that can be used to call a SOAP web service with native android APIs.
Where as REST is so simple & can be used directly without any third party libraries.
I've built a Rails 4 web application with PostgreSQL database and hosted it on Heroku. The future plan for that database is to also be used by one Android application.
I am not completely sure how can I accomplish that. Do I need to build another REST application and host it on Heroku and somehow connect to the same database or there is another way?
How to connect with Android application to that database which is used by the web site? I know I can't connect directly.
Thank you for your guidance.
You don't need another app - just build an API for current one and then you can communicate from Android app to your web application (web app will connect to db and return data).
Have a look at Twitter API as example - you can access different resources and manage them via Twitter API
https://dev.twitter.com/docs/api/1.1
You can build something similar - create rails controllers that access your database and respond with structure you want - preferably JSON format of your models (or something custom if you need)
From Android app you can send request to your API and parse JSON responses - then process data your own way on Android app.
Don't forget about authentication between your Android app and web application - let only your Android app to use it.
I encourage you to browse internet for best practices 'How to create an API' :)
Can we create webservices in Drupal? Our web development team is creating a website in Drupal and they want to build an android application for the same and for that I need to use webservices to access the database.
Have a look at the services module
A standardized solution of integrating external applications with
Drupal. Service callbacks may be used with multiple interfaces like
REST, XMLRPC, JSON, JSON-RPC, SOAP, AMF, etc. This allows a Drupal
site to provide web services via multiple interfaces while using the
same callback code.
It's build for this reason. Drupalize.me android app is built on the services module, so too for many android applications.
Hope this helps... Muhammad.
Can we create webservices in Drupal?
Yes, You can Do it.
I had done it via JSON webservices.
