I would like to create a Java-written RESTFul Web Service, possibly using an eclipse plugin.
This service should be consumed by an android application, using the apache HttpClient.
But my question is, which is the best/ideal technology (server side) to implement this kind of web service?

I got one blog which interacts with servlets... Link as follows
http://groups.google.com/group/android-developers/browse_thread/threa...
In that program 2 libraries were used..
1---> import org.apache.commons.httpclient.HttpClient; 2---> import org.apache.commons.httpclient.methods.GetMethod;
When i check these libraries in my program, its show error....how to resolve this error?
I'm trying to use the Amazon Web Services java sdk jar but it has references to org.apache.commons.httpclient. All I seem to have in my Android sdk is org.apache.commons.http.client, which is a different namespace and obviously causes the build to fail. I'm new to Java and Android dev... is there a way to "map" one to the other or create some sort of symbolic link? If not, does that mean I have to import a "standard" org.apache.commons library?

But when I try to execute it(with some small changes, Post instead of the the Get method) I get a

When this failed I tried using:
CODE:.................
At first I have only overridden "realm" and "nonce" DigestScheme parameters. But it turned out that PHP script running on the server requires all other params, but no matter if I specify them or not DigestScheme doesn't generate them in the Authorization RequestPreperty when I call its authenticate() method. And PHP script returns HTTP response code 200 with a message that PHP script requires cnonce, nc and qop parameters.
To enable logging for apache commons HttpClient in normal Java application I used:

But on android I don't see logs in LogCat.
How can I call a Webservice with a byte[] parameter? Tried using the namedvaluepairs, but they take strings only. I am not using the Ksoap2, we decided to use the HttpClient / HttpPost method.
Here is my code:

I am trying to import the code from this tutorial http://www.anddev.org/bbc_download.php?p=777&item=7
Into my eclipse,the tutorial is oldand I have trouble importing the packages that it referes.
Are those packages deprecated? or I have to manually download and install them into my projects classhpath? if so can someone give me a link on where to find them?
I'm doing a Get and Post method for an android project and I need to "translate" HttpClient 3.x to HttpClient 4.x (using by android).
My problem is that I'm not sure of what I have done and I don't find the "translation" of some methods...
This is the HttpClient 3.x I have done and (-->) the HttpClient 4.x "translation" if I have found it (Only parties who ask me problems) :
CODE:...........
I don't know if that is correct. This has caused problems because the packages are not named similarly, and some methods too. I just need documentation (I haven't found) and little help.
I am trying to download a zip file using HttpCLient 4 and it is going at around .5 (kilobytes/kilobits)? per minute. The file is less than a MB large, and the download will probably take an hour! Am I doing something wrong? How else should I do this?
Here is my current implementation:
CODE:..................
I have a problem.
1 - From a webservice. NET 2008 (vb), I have a method that returns an array of bytes, the byte array is actually a string "Hola Mundo" ("Hello World" in English) compressed with the Class of System.IO.Compression GZipStream.
2 - The method returns the string "Hola Mundo" compressed, and this is what the webservice returns:
CODE:..............
3 - if I do a test from a windows application from Visual Basic. NET to run this method returns me this string and Unzip with another function I have, it brings me the "Hola Mundo" ....
4 - On Android (Eclipse) and I managed to make the request and bring me the previous string ... but do not know how to decompress and show me "Hola Mundo" ...
5 - I have tried several codes from the web, but none work.
I've removed my convoluted and badly malformed question so that it doesn't detract from the very neat and correct answer beneath. Given the (surprising) difficulty of finding an on-line example for doing this incredibly common task, I hope Yoni gets a few more up-ticks for his response.
So the question...How do I use Apache.Commons to upload a file to some destination. I'm using it in Android and uploading to a PHP script, but obviously it can work from any Java program and to any HTTP based listener.
I am trying to login to a site and maintain that session/cookie so that the server will recognize my login, but I am struggling to figure out a way of extracting the cookie from the response and setting into a request to maintain my login. I'm wondering if I should go about taking the header "Set-Cookie" or using a CookieStore. Any help is greatly appreciated. Here is my code that I have, with comments where I think the getHeader/getCookie methods would go.
CODE:.......
In hopes of others better understanding my confusion am adding code that I know DOES work and maintains a session but when I tried to move the code into my actual application it broke somewhere down the line.
CODE:...............
I know for a fact it works, and you can see that in this code I consumeContent() but adding that to the top code didn't seem to make a difference so I left it out.
I am still unable to get the code working in keeping a session going. I am posting the cookies from my current code, along with the cookies of the second code that is working. Perhaps someone will notice an issue, I certainly do not.
CODE:............
Is it possible to implement the Model-View-Controller pattern in Java for Android? Or is it already implemented through Activities? Or is there a better way to implement the MVC pattern for Android?

I am currently trying to integrate a live search functionality in android. I use a customized Autocomplete widget. The widget itself provides me with a threshold to only start a query after a certain amount of characters have been typed in. But what I also want is that a query only starts, say if a user has stopped typing for 2 seconds.
As I load my contents with a AsyncTask I tried blocking the doInBackground function by calling Thread.sleep() right at the beginning. If the user would then continue typing the program would look after an existing task, cancel it and start a new one. This was my idea. But it doesn't quite work the way I expected. Sometimes it sends out queries even if the user is still typing, sometimes queries are canceled after the users stopped typing. Do you have any ideas on this or maybe a better way to solve this? Here are the code snippets:.....................

View 2 Replies View RelatedI have a custom camera application. I'm using a BroadcastReceiver to launch it when the Camera button is pressed. Unfortunately, once my camera app is launched the camera button KeyDown event used to launch my camera activity is also passed to it, which cause it to immediately attempt to capture a picture. Is there a way to consume the KeyEvent so that this doesn't happen?

i have a web service made in php now i want to consume it in android can any one guide me how to achieve this?
i have tried many code samples on net but failed to achieve this goal.
i am using Eclipse with ADT.
I am still not able to save a picture when I send an intent asking for a photo to be taken. Here's what I am doing:
Make a URI representing the pathname
android.content.Context c = getApplicationContext();
String fname = c.getFilesDir().getAbsolutePath()+"/parked.jpg";
java.io.File file = new java.io.File( fname );
Uri fileUri = Uri.fromFile(file);
Create the Intent (don't forget the pkg name!) and start the activity
private static int TAKE_PICTURE = 22;
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE );
intent.putExtra("com.droidstogo.boom1." + MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult( intent, TAKE_PICTURE );
The camera activity starts, and I can take a picture, and approve it.
My onActivityResult() then gets called. But my file doesn't get written.
The URI is: file:///data/data/com.droidstogo.boom1/files/parked.jpg
I can create thumbnail OK (by not putting the extra into the Intent), and can write that file OK, and later read it back).
I have HTC Desire, and I know that I have QuickOffice. The problem is when I put a word or excel file on the .quickoffice folder on my phone, nothing comes up on the mobile when I disconnect. Therefore I was wondering if anyone could recommend me a program where I can either write, or read written files like Word and excel files?
View 1 Replies View RelatedI want to access camera pictures and camera pictures only. I could not find a specification of how the default camera application stores pictures...
1) Is /sdcard/DCIM a standard of any kind? On the Android devices I've used, it looks like the default camera app always writes to this location. Are there devices where pictures are written to a different location? 2) Is it specified that camera JPEGs will always be accessible on the file system? (And not in some private database for example?)
I'm hoping that if the above two are true, then I can simplify my code by simply reading the jpeg's in /sdcard/dcim. Or do I have to use MediaStore.Images.Media.query() for reliable access to camera images?

I am using Ksoap2-Android for consuming the WCF Services.
For the dotnet client we keep the allowCookies="true" in our binding configuration and it sends the same sessionid and keeps my sessions intact in my WCF services (My services are
interdependent and use the sessions).
Any one know any such setting for ksoap2-android, that will allow me to consume the
WCF service keeping my session intact on the server.
Currently when i make a new call to the service, the sessionid gets changed and all my
session variables clear out and loose their values.
why after upgrade to 2.1 can not Written Chinese ,i can't written chinese in my sms or mms
View 1 Replies View RelatedMy application writes data to a file in the SD card directly. There are no errors during the write. But, the file never shows up on the card, in the file browser (on the device - I use Glance). Where did the file go? When trying to browse the device from my desktop, I notice the USB Mass Storage option is missing guess that's expected since others in the forum explain that it was removed in this version. But, I can't get my PC to browse the memory card when it's stored in the phone. This all just seems to add up to a flaky memory management problem, but I can't be sure.

View 3 Replies View RelatedThis would apply to any widget. It just so happens that on most screens (all but my home screen) I have the "Beautify Smaller Home" or whatever its called at the very top. I like easily seeing the time from each screen. And I think it looks nice. Beautiful might be a stretch... but I understand the marketing.But the hypothetical question still applies. If I had the "music" widget or the "messaging" widget on EVERY page. Would that widget use more battery than just one instance? In other words, does EACH INSTANCE of the widget poll for data? Or does the process just poll for data and then each widget just repaints itself on its respective screen as appropriate? I need to know! I'm wondering if I disable "beautiful home" from all but one screens if my battery life will improve.What do you think? Are there any hard-core techies out there that can help me figure it out?
