Currently the app on the device polls the server with a unique ID that it received when it made the request. This could easily be changed to use SMS but the current implementation hopefully makes it easier for the competition judging since they don’t have to simulate an SMS message being sent to the device for it to work. Since the focus for the ADC is on the device end user experience I decided to keep it as simple as possible.

Just have one more questions …
in which way do you get the acceptanze back from the taxi server? SMS or what notification intent is the android app listening? (last 3 screenshots)

Thanxx

Interesting idea, let us know how it goes. As for the question regarding connecting to the web server, I use the URL’s openConnection() method like this:


URLConnection conn = url.openConnection();


You can then set it up for input or output and use I/O streams for reading/writing. I’ve seen other ways as well but this one seems easy to me. Hope this helps and good luck!

Is it possible if you can share the code where I can make request to Servlet using HTTP connection on Apache web server?

I have function as belows:
private void invokeServlet(URL url) {
// TODO Auto-generated method stub

HttpURLConnection hc =null;
hc = new HttpURLConnection(url);
InputStream is = null;
OutputStream os = null;
StringBuffer b = new StringBuffer();

try
{
hc.connect();
}catch(Exception e)
{
e.printStackTrace();
}
}

Here it doesnt allow me to call the constructor
hc = new HttpURLConnection(url);

Actually we are building the relevant application called Taxi Ride Sharing where based on the user location, the system will display no of users who want to share the ride when they have same destination. This is very typical case in metro cities like San Francisco and NY..

I will higly appreciate if anybody has relevant material.

Once we are done with this app, we will post it here as well anddev.org

@Christian, Sounds like an interesting project you are working on. Here are some responses to your questions:

- The server is implemented in PHP, for no particular reason, it was just convenient because of my hosting provider.
- I’m using normal XML, there is not alot of data being exchanged and I wanted to keep it lightweight.
- The data is parsed on the Android side using the Simple API for XML (SAX).

Hope this helps and thanks for visiting!

Very interesting this app - think it could work good. Cross the fingers for the chellenge!

Have the same group of people in mention because I’m making a diploma thesis of android for mobile communities at the telematic area. So i want to create a mobile community. Maybe you could give me some answers of your implementation.

- Your Server has implemted a webservice in php?
- Which technologies did you use? SOAP XML RPC ? Normal XML? For the communication between android and the Server
- How did you parse the answer in Android or did you make this with a sms and an intent receiver of this incoming thing?

Thanxx a lot for answering!
