I am developing a news application. I dont want users to register in the application. When users download the application, data should be populated in the app from the server and any data added should be updated in the application.
How to update the data when any news has been added i.e how to identify users and send the data?
Your server don't need to track the new user. It is your app which will tell the server about the user. Write your data fetching code on the very first screen of your application (say Splash screen) and do check if there is any update on the server end
You can use the concept of fetching data on your Splash Screen, but if you dont want your user to get stuck you can use Intent Services to fetch your data in background, Once your data is received from server you can show it to the user.

I am working on an application which shows so many data to user, but problem is that it takes too much time to load data even we are using paging too. I want to know how facebook shows the data to user. are they storing the data in database first and then display it to user? if yes then how they maintain the user activity on that.
I want to use a facebook friend picker as a UI for integrate a blacklist in my app.
What I want to do is show user's friends which use my app and allow the user to select some of them and put them in a blacklist.
I have no problem with that but how can I re-show the previous user selection when he comes back to this picker a second time?
I've tried the way suggested by il4.serg here and using a json to get the friends blocked, but when I try to add another friend, in the setOnSelectionChangedListener I only get data from the already selected users, and if I touch a selected friend the activity crashes....
i'm developing an android application which allows different users to login and see a list of favourite songs.
Each user has its list of songs, and a song is an instance of the corresponding class Song, with some attributes (singer, year, title...). The MainActivity contains the form for the login, so the user has to set its Name and Password. After login, a second activity is started, and it contains the ListView with the user's favourite songs.
How can i associate a single user to its corresponding song's list?
I thinked to use a database to store the songs, but then?
Look at Parse it's very easy to use and let you focus on your android App, instead of spending much time writing and configuring a server-side application.
You need also to implement on your android application a service to handle json ( or xml, it's your choice ). This is an awesome library to handle json JSONP.
Look also to this link for an overview on RESTfulservices.
For example (getting user info):
You need an info on userA.
You format a json with the right info.
Start an http request to your server. It will answer you with another json containing some info.
Parse this json recieved and use the data in your app.
I hope I made myself clear.
Hello I am new to Android .I have been given an Android project to do. As a part of my project I need to do the following :
1)Create an Android application that takes 3 inputs from user via EditText namely id,address and contact no, and has a submit button at the end to send that data
2)After clicking the submit button , a web service that we will create using Netbeans should get invoked and display it's contents on the phone to the user
The web service will basically contain some predefined data entries that I want to display it to the user with a checkbox
say eg. xyz
yax
where 'xyz' and 'yax' are contents of my web service. The user selects any checkbox say 'xyz' , clicks another submit button below and the entire data namely id , address ,contact no , and now 'xyz' goes into a mysql database.
3) After reading this I am now aware of how to create a web service but the problem I have is how to invoke that web service from an android phone ???
Can someone please help me ?
You can directly use web-service from URL.
