I have an android APP. I need to connect to a remote D.B. on the internet. All i know is that i have to use a Web Service, installed on the remote DB server.With my Android APP i have to connect to the web service, and the web service will do the logical operations to get the necesary data from the D.B. and will send them to me. the web service is not a problem, i have a friend that will do it (i have no idea about web services), but i dont know how i have to do the connexion with the Web Services, and also i dont know how have to be the functions of the Web Service.I have searched for tutorials on google but i can't find a good tutorial for beginners like me.can someone give me a little help? for example, a good tutorial for beginners connecting android to a remote DB with webservices?

How I'm able to do what I've written in the topic. I've looked through many tutorials on AsyncTask but I can't get it to work. I have a little form (EditText) that will take what the user inputs there and make it to a url query for the application to lookup and then display the results.
What I think would seem to work is something like this: In my main activity i have a string called responseBody. Then the user clicks on the search button it will go to my search function and from there call the GrabUrl method with the url which will start the asyncdata and when that process is finished the onPostExecute method will use the function activity.this.setResponseBody(content).
This is what my code looks like simpliefied with the most important parts (I think).
CODE:.......................

The Facebook app on my Desire doesn't seem to be working. A couple of days ago I couldn't refresh the "Notifications" page, it gave me a brief message about an error. Now I'm getting the same message on the News Feed page
"An error had occurred while fetching data. [101/Invalid API Key]". I'm on T-Mobile, if that helps.
Anyone else having this issue or any advice?

Now I want to periodically (say 2 mins) fetch the new data from the server and add it to view.Periodically fetching data (polling) from the server in Android.

I am developing an application which require accessing a website for data, and will show that data on device. I wants to fetch data from Internet in background and show ProgressDialog or ProgressBar on
device and when application receive response from server app will dismiss the dialog or bar and will show data .
For this i am using AsyncTask -
code for AsyncTask is as follows--
CODE:..........
And calling this code as follows--
CODE:...........
But ProgressDialog is not shown.(I guess the reason for it is the thread is not complete and android invalidate only when thread has completed).
My Questions-
1- If my guess is right ? If yes then how I should implement it?
2- If there is any other better way to do this?

I think this is the right place to look for some tips and stuff for android programming ahah. So I am completely new at all this java/android programming. My friend gave me the challenge to parse some json data as a listview. I was succesfully able to display the content as a textview however not everything appeared. Only the last few line of text showed up. He told me that by putting it as a listview everything should go well. Now setting up a listview isn't the same thing as setting up a textview. So my question is with all the code that I have how can I display the content as a listview.
[HIGH]DefaultHttpClient httpclient = new DefaultHttpClient(new BasicHttpParams());
HttpPost httppost = new HttpPost("http://ec2-54-213-155-95.us-west-

Can you point me to some code samples that retrieve data from Android and return it to the browser. The browser fills in some form data fields and returns the form to the server for processing The application can be seen at http:gpsmancer.com/ourtown-B

I'm starting to develop an application for Google Android and heavily relying on a web API that can deliver data in a restful way via json or xml. I now have to decide which library to choose.
I saw that google includes org.json classes in the API but haven't tested them yet.
How are your experiences? What library/API should I use and why?

I am currently trying to send some data from and Android application to a php server (both are controlled by me). There is alot of data collected on a form in the app, this is written to the database. This all works.
In my main code, firstly I create a JSONObject (I have cut it down here for this example):
JSONObject j = new JSONObject();
j.put("engineer", "me");
j.put("date", "today");
j.put("fuel", "full");
j.put("car", "mine");
j.put("distance", "miles");
Next I pass the object over for sending, and receive the response:
String url = "http://www.server.com/thisfile.php";................

I have a Windows web server already set up with a website (unlimited application pools) and I want to be able to access a database on that server via the Android app I'm developing. How can I do this? Can someone point me to a tutorial or give code example of how this cross-platform (Android/Java to ASP.NET/C#) communication can be done? (I'm trying to create a leader board or global scoreboard for my Android game on my server.)

I created the following method for retrieving stored settings from the database:
public String getEntry(long rowIndex){
String value = "";
Cursor c = db.query(DATABASE_TABLE, new String[] {KEY_NAME, VALUE}, KEY_NAME + "=" + rowIndex, null, null, null, null);
int columnIndex = c.getColumnIndex(VALUE);
int rowsCount = c.getCount();
if(rowsCount > 0){
String value = c.getString(columnIndex);
}
return value;
}
On debugging I can see cursor c contains two columns and one row but when it comes to line
String value = c.getString(columnIndex);
it throws the CursorIndexOutOfBoundsException although columnIndex = 1 which should point to a valid entry. Does anyone know what could be wrong here?
