&lt;a href=&quot;http://restlet.org&quot;&gt;Restlet&lt;/a&gt; is an excellent REST framework and has an Android edition.

Any HTTP Client library should be perfectly adequate to interact RESTfully with a web API.   E.g. http://developer.android.com/reference/org/apache/http/client/HttpClient.html

try out Spring Android - is has very handy class RestTemplate.

I&#39;m also looking for a SMALL solution for rest client on Android. After a quick comparison, I found:

 - **Resting** v0.7: resting-0.7-dev-release-android.jar - **1.3MB** (all-in-one according to
   the doc)
 - **Restlet** v2.1.2: org.restlet.jar - **728KB** (however must &gt; 1MB after adding httpclient extention and json extention)
 - **Spring for Android** v1.0.1: spring-android-core-1.0.1.RELEASE.jar 113KB + spring-android-rest-template-1.0.1.RELEASE.jar 186KB + gson-2.2.3.jar 194KB = **493KB** (without auth support, otherwise spring social will be a dependency)

Please correct me if any miss.

I am using [JSch][1] for sftp communication, now i want to use facilitate the key-based authentication, key is loaded on client and server machine once by my network team and all later communication would be only user based for which we have loaded the key.

    sftp -oPort=10022 jmark@192.18.0.246

as `tjill@192.18.0.135`

like this command work fine and connect to the sftp, how i can achieve this functionality programmatically.

if it is not possible using JSch, please suggest some other library. I came across [Apache SSHD][2].

I&#39;m about to build an Android application that will use a RESTful Web Service. I don&#39;t want to write the REST client by myself, as I want it to be as effective and stable as possible (this is the first time I&#39;m using REST).

Are there any (free) frameworks or utilities avaibale for Android/Java that I can use in my project?

<p>I'm about to build an Android application that will use a RESTful Web Service. I don't want to write the REST client by myself, as I want it to be as effective and stable as possible (this is the first time I'm using REST).</p>

We use the Java preferences in some of our apps and haven&#39;t really noticed this since the utility that makes the calls is fairly old and was written in Windows XP days. But it seems the Java preferences are no longer stored in the registry in Windows 7 - or they are stored somewhere different. 

I&#39;m expecting it to be in:

`HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Prefs`

But I don&#39;t see it there.

What makes it wierder, is that when I run this app:

	public static void main( final String[] args ) throws BackingStoreException {

		Preferences systemRoot = Preferences.systemRoot();
		Preferences preferences = systemRoot.node( &quot;com/mycompany/settings&quot; );

		systemRoot.put( &quot;foo&quot;, &quot;bar&quot; );
		systemRoot.put( &quot;baz&quot;, &quot;lolz&quot; );
		System.out.println( &quot;-------------------------------&quot; );

		String[] keys = preferences.keys();
		for( String key : keys ) {
			System.out.println( key );
		}

		System.out.println( &quot;-------------------------------&quot; );

		keys = systemRoot.keys();
		for( String key : keys ) {
			System.out.println( key );
		}
	}

It actually writes (I can comment the put out and run it again and it works) but I don&#39;t see the new keys in the registry.

Also, I can&#39;t seem to see this documented anywhere. Thanks in advance.

**EDIT #1** The only reason this matters is that the setting changes dependent upon which environment it is ran. This being said, it is often useful to simulate that environment by inserting the registry keys manually and then doing some checking.

I was running as admin, yet I did not see the keys in the registry where I expected them to be.

Where are the Java preferences stored in Windows 7?

I want to build a REST Client on an android phone.

The REST server exposes several resources, e.g. (GET)

    http://foo.bar/customer		 List of all customer
    http://foo.bar/customer/4711	The customer with id 4711
    http://foo.bar/customer/vip 	List of all VIP customer
    
    http://foo.bar/company			 List of all companys
    http://foo.bar/company/4711		The company with the ID 4711
    http://foo.bar/company/vip 		List of all VIP companys

I (think) I know how to talk to the REST server and get the information I need. I would implement a REST Client class with an API like this

    public List&lt;Customer&gt; getCustomers();
    public Customer getCustomer(final String id);
    public List&lt;Customer&gt; getVipCustomer();
    
    public List&lt;Company&gt; getCompanies();
    public Customer getCompany(final String id);
    public List&lt;Customer&gt; getVipCompanies();

Referred to the presentation &quot;[Developing Android REST client applications][1]&quot; from Virgil Dobjanschi I learned that it is no good idea to handle the REST request in an Worker Thread of the Activity. Instead I should use the [Service][2] API.

I like the idea of having a Singleton ServiceHelper which binds to a (Local) Service but I am afraid that I did not understand the Service concept correct.

For now I do not understand how to report a REST call result (done asynchrounous in a Service) back to the caller Activity. I also wonder if I need ONE Service which handles all REST requests (with different return types) or if I need a dedicated service for each REST request.

Probably I have many other understanding problems so the best thing for me would be a **sample application** which meets my needs. My use case is not unusual and I hope there is in example application out there.

**Would you please let me know!**

Any other suggestions which points me in the correct implementation direction are also helpful (Android API-Demo does not match my use case).

Thanks in advance.

I&#39;m taking a C# class right now and I&#39;m trying to find out the best way of doing things. I come from a Java background and so I&#39;m only familiar with Java best-practices; I&#39;m a C# novice!

In Java if I have a private property, I do this;

    private String name;
    
    public void setName(String name) {
       this.name = name;
    }
    
    public String getName() {
       return this.name;
    }

In C#, I see that there are many ways of doing this.

I can do it like Java:

    private string name;
    
    public void setName(string name) {
       this.name = name;
    }
    
    public string getName() {
       return this.name;
    }

Or I can do it this way:

    private string name;

    public string Name {
       get { return name; }
       set { name = value; }
    }

Or:

    public string Name { get; set; }

Which one should I use, and what are the caveats or subtleties involved with each approach? When creating classes, I am following general best-practices that I know from Java (especially reading Effective Java). So for example, I am favoring immutability (providing setters only when necessary). I&#39;m just curious to see how these practices fit in with the various ways of providing setters and getters in C#; essentially, how would I translate best-practices from the Java world into C#?

**EDIT**

I was posting this as a comment to Jon Skeet&#39;s answer but then it got long:

What about a non-trivial property (i.e., with significant processing and validation perhaps)? Could I still expose it via a public property but with the logic encapsulated in `get` and `set`? Why would/should I do this over having dedicated setter and getter methods (with associated processing and validation logic).

Getters, setters, and properties best practices. Java vs. C#

When loading a widget if it cannot find a resource or something it says Problem Loading Widget. That&#39;s all! Amazing! This message remains on the home screen and does not even say which widget it had trouble loading. 

I figured it out by trial and error but I would like to know if there are any places to find the error message when this occurs. Where will Android say what problem it had loading the widget or even which widget it failed to load?

I&#39;m working on a Java application at the moment and working to optimize its memory usage. I&#39;m following the guidelines for proper garbage collection as far as I am aware. However, it seems that my heap seems to sit at its maximum size, even though it is not needed.

My program runs a resource intensive task once an hour, when the computer is not in use by a person. This task uses a decent chunk of memory, but then frees it all immediately after the task completes. The NetBeans profiler reveals that memory usage looks like this:

![Java program memory usage][1]

I&#39;d really like to give all of that heap space back to the OS when not in use. There is no reason for me to hog it all while the program won&#39;t even be doing anything for at least another hour.

Is this possible? Thanks.

Is there a way to lower Java heap when not in use?

Let&#39;s say I have a vertical linearLayout with :

    [v1]
    [v2]

By default v1 has visibily = GONE. I would like to show v1 with an expand animation and push down v2 at the same time.

I tried something like this:

    Animation a = new Animation()
    {
        int initialHeight;
        
        @Override
        protected void applyTransformation(float interpolatedTime, Transformation t) {
            final int newHeight = (int)(initialHeight * interpolatedTime);
            v.getLayoutParams().height = newHeight;
            v.requestLayout();
        }
        
        @Override
        public void initialize(int width, int height, int parentWidth, int parentHeight) {
            super.initialize(width, height, parentWidth, parentHeight);
            initialHeight = height;
        }
    
        @Override
        public boolean willChangeBounds() {
            return true;
        }
    };

But with this solution, I have a blink when the animation starts. I think it&#39;s caused by v1 displaying full size before the animation is applied.

With javascript, this is one line of jQuery! Any simple way to do this with android?

I&#39;m trying to explore the posibilities with running a native web-app on different platforms using HTML5. Currently, an `&lt;input type=&quot;date&quot;&gt;`field just opens the standard soft keyboard on Android and iOS. I suppose that in the future the mobile OS&#39;s soft keyboards will include date pickers and such - just as `&lt;select&gt;` invokes the native select today.

Since this isn&#39;t implemented on either Android or iOS, but is implemented in native UI, is it possible for a web-app to invoke the native date picker, i.e. when clicked on?

This would make it possible for us to stop using JavaScript libraries like jQuery mobile and YUI.

If my question is in any way unclear, please tell me. Thank you in advance :-)

My app is using JSoup to download the HTML of a message board page (let&#39;s say in this case it is a page containing the posts of a given thread). I&#39;d like to take this HTML, strip out unwanted items, and apply custom CSS to style it to be &#39;mobile&#39; in a WebView.

Should I inject the styles into the HTML as I process it (since I will be processing it anyway) or is there a good way to add a CSS file to my app&#39;s assets and simply refer to it. I figure the latter would be ideal, but unsure how to go about it.

I see hints in WebView&#39;s [loadDataWithBaseURL][1] that you can refer to local assets, but not sure how to utilize it.

I&#39;d like Jackson to deserialize a class with the following constructor:

    public Clinic(String name, Address address)

Deserializing the first argument is easy. The problem is that Address is defined as:

    public class Address {
      private Address(Map&lt;LocationType, String&gt; components)
      ...
    
      public static class Builder {
        public Builder setCity(String value);
        public Builder setCountry(String value);
        public Address create();
      }
    }

and is constructed like this: `new Address.Builder().setCity(&quot;foo&quot;).setCountry(&quot;bar&quot;).create();`

Is there a way to get key-value pairs from Jackson in order to construct the Address myself? Alternatively, is there a way to get Jackson to use the Builder class itself?

I have JSON object as follows:

    member = &quot;{interests : [{interestKey:Dogs}, {interestKey:Cats}]}&quot;;

In Java I want to parse the above json object and store the values in an arraylist.

I am seeking some code through which I can achieve this.


Parsing JSON Object in Java

I&#39;ve got a problem.

Using ajax I sent a correctly formed JSON object using:

				$.ajax({
					type: &quot;POST&quot;, 
					url: SITE_URL+&#39;/data.php&#39;,
					dataType: &quot;json&quot;,
					data: { ajax: 1 },
					success: function(data) {
						console.log(data);
					}
				});

However, Opera and Chrome, although receiving the same object, print out the object in an incorrect order, it seems like they both perform a sort by ID number instead of just leaving it alone!

Is there a way to stop this auto sort?

Edit, after finding out it is a sort by index number I&#39;m thinking the best method might be to not use the index for storing the object_id and instead store the id number which I want to order the object by.

However I would still like to know if there is a way to stop the sort.

Thank you

Edit2, I&#39;ll just like to note that I&#39;m going to work on a different way of doing this, as I feel like I&#39;m abusing objects with this method. However I&#39;d still like to understand why Opera and Chrome feel it is their right to change the order of my objects IDs:

The problem would be me trying to save processing power, lets say we have people with an ID,

1.John, 2.Frank and 3.Sally. However each of these people have a hight property set (and other things). 1.John.180, 2.Frank.220, 3.Sally.150. To save on processing, my I request the result of people be sorted by their height so I get an array of 2, 1, 3 with their other properties. I JSON this array and send it to the browser.

Now FF will keep the new order
People[1] would still be John but in a For n as person loop they&#39;ll be out of order.

If I can&#39;t get around this I&#39;ll just have to not bother sorting at the SQL stage and add extra looping and sorting into an array in the JS stage although I wanted to avoid more stress on the browser as its already a Js heavy page.

Many thanks

From what I can read on [json.org](http://json.org/), all JSON strings should start with `{` (curly brace), and `[` characters (square brackets) represent an array element in JSON.

I use the `json4j` library, and I got an input that starts with `[`, so I didn&#39;t think this was valid JSON. I looked briefly at the JSON schema, but I couldn&#39;t really find it stated that a JSON file cannot start with `[`, or that it can only start with `{`.

I&#39;m writing an iPhone app as a hobby project and it will need a web service to provide it with data. It&#39;s not very different from what I do at work, but at work I only write views and controllers. Someone else is responsible for writing the model and usually the clients provide the web service.

I have done some web programming before, back when everyone were using MySQL and PHP, so my skills are a bit outdated, but I&#39;m confident that I would be able to pull it of using the techniques I already know. However, I don&#39;t want to waste my time using obsolete tools. I&#39;ve figured out that the state of the art would be to write a REST API. I was thinking that there should be some pretty good frameworks out there that pretty much just gives you a REST API with CRUD functionality as soon as you&#39;ve defined a model.

I guess my question is: What would be the fastest way to get a REST API up and running? I really just want to focus on writing the iPhone app and not spend too much time on this API. It would be great if I could get web administration and revision history too. I should also add that the API isn&#39;t supposed to be public, so support for authentication would be great as well.

Just to be clear. I wouldn&#39;t mind a PHP framework. In fact it could possibly be better since I know that my current hosting supports it.

How to write a REST API?

I&#39;d like to follow the RESTful pattern for my new django project, and I&#39;d like to know where the parameters are when a PUT/DELETE request is made.

As far as I know, I only see GET &amp; POST QueryDict in the request, no others.
Is Django adding a new PUT or DELETE QueryDict regarding to the request, or does it add the parameters to GET or POST QueryDict ?

Thanks for your help.

Django - Where are the params stored on a PUT/DELETE request?

I&#39;m currently designing and implementing a RESTful API in PHP. However, I have been unsuccessful implementing my initial design.

    GET /users # list of users
    GET /user/1 # get user with id 1
    POST /user # create new user
    PUT /user/1 # modify user with id 1
    DELETE /user/1 # delete user with id 1

So far pretty standard, right?

My problem is with the first one `GET /users`. I was considering sending parameters in the request body to filter the list. This is because I want to be able to specify complex filters without getting a super long url, like:

    GET /users?parameter1=value1&amp;parameter2=value2&amp;parameter3=value3&amp;parameter4=value4

Instead I wanted to have something like:

    GET /users
    # Request body:
    {
        &quot;parameter1&quot;: &quot;value1&quot;,
        &quot;parameter2&quot;: &quot;value2&quot;,
        &quot;parameter3&quot;: &quot;value3&quot;,
        &quot;parameter4&quot;: &quot;value4&quot;
    }

which is much more readable and gives you great possibilities to set complex filters.

Anyway, `file_get_contents(&#39;php://input&#39;)` didn&#39;t return the request body for `GET` requests. I also tried `http_get_request_body()`, but the shared hosting that I&#39;m using doesn&#39;t have `pecl_http`. Not sure it would have helped anyway.

I found [this question](https://stackoverflow.com/questions/978061/http-get-with-request-body) and realized that GET probably isn&#39;t supposed to have a request body. It was a bit inconclusive, but they advised against it. 

**So now I&#39;m not sure what to do. How do you design a RESTful search/filtering function?**

I suppose I could use `POST`, but that doesn&#39;t seem very RESTful.

How to design RESTful search/filtering?

I have a requirement for RESTFul webservices. It is up to my team to decide whether to go with Jersey or Restlet or RESTEasy or anything else. after omitting other frameworks, we are not able to choose between RESTEasy and Jersey.

Since both of them seem to be almost the same, what should we consider?
 
The client API should be simple and rich. We are already using JBoss 5.1 in production.

Please let me know the pros and cons of Jersey and RESTEasy. Except that it is from JBoss, I&#39;m not able to find any valid point over Jersey.
