I need to explore for my project use of web services on Android. I know that there is no official library for XML - RPC web service.
But there is for REST XML and i need to test it.

View 2 Replies View RelatedI need to send asynchronous calls to the server. During network connection this works fine. How ever if i disable my LAN from Network connections android will through a socket exception after the specified timeout for that particular call. Now the issue that i face is the time out happens in a synchronous manner. Though both the calls has been started in a thread the timeout is not happening at the same time. If i keep the timeout as 20sec i am getting a socket exception for the first call after 20 sec and after the next 20 sec i get the timeout for the next call. Why is this happening..? I am not opening two connections asynchronously in this case. I am attaching a sample code that can replicate the above scenario. Code...
View 9 Replies View RelatedI'm making an http request. I'm on a platform (android) where network operations often fail because the network connection might not be immediately available. Therefore I'd like to try the same connection N times before completely failing. Was thinking of something like this:
DefaultHttpClient mHttp = ...;
public HttpResponse runHttpRequest(HttpRequestBase httpRequest)
throws IOException
IOException last = null;
for (int attempt = 0; attempt < 3; attempt++) {
try {
HttpResponse response = mHttpClient.execute(httpRequest);
int statusCode = response.getStatusLine().getStatusCode();
if (statusCode == 200) {
return response }
} catch (IOException e) {
httpRequest.abort();
last = e;
throw last;
I'm mostly worried about the connection being in some state which is invalid on subsequent retries. In other words, do I need to completely recreate 'httpRequest', should I avoid calling httpRequest.abort() in the catch block, and only call it in the final failure?
I am using org.apache.http.*; API's to make HTTP Post Connections over Internet from the Android Application. I added the Internet Permissions in the Manifest file and it works fine. Now i want my application to make the same HTTP requests over WiFi network through which the handset is connected.
Do i need to make code changes to achieve this? Do i need to add some permissions? as i am unable to make requests...
is there a way to force a connection (http) to go over OTA (Over-The- Air) even if you have a wifi connection?

I need to make HTTP request on Android using GSM connection, not Wifi. My current solution is to disconnect from all wi-fi connections and perform a request. Is there any better solution? I could not find any relevant methods in the API (I looked in package org.apache.http, but it seems it is completely unaware of what type of connection should be used).

View 2 Replies View RelatedI'm facing an annoying problem here. My application is connected to a server that sends some data from time to time. It's some kind of eventing server. In order to receive data, I'm connecting to the server with an HttpURLConnection, retrieve the response InputStream and loop on it with the read method. The connection is always open. The distant server is cutting the connection every 5 minutes (for test purpose). When connection is closed, my application has to reconnect again. We detect a Connection Reset by Peer exception when the server closes the connection. The problem is that most of the time, I never receive the Connection Reset by Peer exception. So my application can't know that is has to reconnect and it's stucked on the read instruction. The InputStream.Read() method shouldn't always raise an exception if the connection is closed? What can I do to always detect Connection Reset by Peer exception?

what are the settings do you have to change in order to completely stop any data connection? I have an unlimited data plan so I don't care now that there is a lot of apps using my connection, but going overseas soon, the roaming charges are really expensive. I found some settings (like sync) that I can configure not to use data connection but I am not sure if these are all.
View 8 Replies View RelatedI assume that when I do a read on the inputstream, it blocks until it gets more data to read.
I also assume that when the connection is closed, the read throws an IOException.
The problem is that sometimes when I change the connection from carrier to WiFi or from WiFi to carrier, the read just gets stuck and never throws the IOException.
The SDK is 1.5 and the phone a HTC Hero.
This behavior is quite ugly for me because I need to stay always connected.
Does someone else have ever seen this problem ? Is it a bug or am I the bug?

View 8 Replies View RelatedI know this has most likely been discussed many times. But I am looking for a decent email widget.
At the moment I am using the default htc email widget, however when ever I read an email from my gmail account it doesnt update the read status so it still shows as unread.
I would like one that would update the read status and possible the support for unified inbox so I can see new mail from hotmail account and gmail.
I'm using ThreadSafeClientConnManager to manage a pool of client connections, because my application has several threads, which are simultaneously connecting to a webserver.
Abstract sample code:
CODE:..............
Now lets say on of this threads is downloading a large file, but then the user of my application is switching to another activity/screen. Therefor the file is needless and I'd like to abort this download connection.
In ThreadSafeClientConnManager I found this method: public ClientConnectionRequest requestConnection (HttpRoute route, Object state) Returns a new ClientConnectionRequest, from which a ManagedClientConnection can be obtained or the request can be aborted.
So far I've been using:
CODE:.........
Now from what I understand, I've to use:
httpclient.getConnectionManager().requestConnection(HttpRoute route, Object state);
And that's the point where I'm stuck. I assume that for the route I can just use new HttpRoute(new HttpHost("10.0.0.1")) or whatever my server is, but what to put in for Object state?
And second, as soon as I've the ClientConnectionManager I can call getConnection(long timeout, TimeUnit tunit). But then from there, how I do I execute my HttpGet httpRequest = new HttpGet(URL_TO_FILE); as I did before with HttpResponse response = (HttpResponse) httpclient.execute(httpRequest);?
I've been gone through the documentation and tried out quite a few different things, but I wasn't able to obtain a working solution. Therefor any suggestions and/or code examples are more than welcome.
Whenever a application needs internet and connection fails, I get a message dialog

I'm coding a very basic FTP client on top of my application and I have 2 activities. The first one is the file explorer and the second one is the image viewer. Once I click on the image filename on the explorer, I want to pass the connection to the other activity to handle extra stuff. Basically, I want to keep the same org.apache.commons.net.ftp.FTPClient object (which handles the connection) alive in-between the 2 activities. I know I can't pass an object inside an intent so I don't know what my best bets are.

View 3 Replies View RelatedI tried the free version. I like it. I want the additional functions in the paid version. Its only a few bucks. So I created an account in google checkout via my computer. Yes I used the same email as on my phone. It took the info just fine. But when I try to buy the app it says Invalid Credit card. I reentered it a couple of times, no help. So then I chose the option of adding a card at time of purchase. Same deal, takes everything fine, then says invalid credit card. This credit card works just fine and does not have any over limit issues. Google has no customer service, so I am dead.
If google wants to be a consumer company with things like checkout, they need to have some option to get to a human being (even in some third world country) or they are dead.
Any ideas how I buy an app now?
Do I have to wait 24 hours after creating my google acct to use it?
