Jun 22, 2010

I'm passing in parameters and returning string values, but all I receive is: org.apache.http.conn.EofSensorInputStream. Do I need to do something special in my web service to access the parameters being passed?

Android :: GetFromLocationName Always Throws IOException First Time - But Is Successful Second Time With Same Input

May 29, 2009

My calls to getFromLocationName() always fail the "first" time I start my app. I catch the IOException which has reason:

Unable to parse response from server

Then I make a second call and it succeeds. Once things are "awake" all future calls to getFromLocationName() succeed, it's just that first one, and there is a ton of latency.

I haven't run this on a device yet, just in the emulator. This seems like a network problem, but it is so reproducible I'm thinking I'm not initializing something properly. I'm using Android SDK 1.1.

Android :: HttpPost And Byte[ ] ?

Jul 14, 2010

I am dealing with http post method on Android. I have successfully send simple string pairs using HttpClient and HttpPost class with the NameValuePair as entity. However now I want to send a simple array of bytes[]. Unfortunately the only entities I have found for the HttpPost class are the NameValuePair and FileEntity. However my byte[] is not from a file. Wirting it to a file and then sending by the FileEntity seems to be pointless and stupid. How can I send this array using default HttpClient and HttpPost class?

Android :: IOException On SAX Parsing

Apr 25, 2009

I'm trying to parse an XML file from res/raw or assets/ using the javax SAX parser. When the file is too large (~ 1MB), the parse(...) method throws an IOException without further information, such as message or inner exception. When I reduce file size to e. g. 600 kB, it's working again.

Android : How To Send An Image Through HTTPPost?

Feb 7, 2010

I'm creating an activity which needs to upload an image to a webservice using their api. I found that if i use UrlEncodedFormEntity and send the image data through that. the webservice doesn't receive that. ( at least it will not be able to read that .) In fact if i add some vars to send with the image data ( like name of the file, filesize ) they can be read from the webservice but the image data still doesn't appear if i try to read it serverside.

Android :: IOException On Geocoder.getFromLocationName

Jul 29, 2010

I am trying to get the geo codes for an address.

I am using: Geocoder geocoder = new Geocoder(GeoNoteEditor.this, Locale .getDefault()); List<Address> addressList = null; addressList = geocoder.getFromLocationName(addressString, 1);

The problem is that I am getting an IOException sometimes when I call getFromLocationName for the same addressString. This does not happen all the time. When I get the IOException, if I repeat the getFromLocation call, sometimes it works sometimes I get the IOException again.

How do I prevent the IOException from happening?

Android :: IOException While Reading A Raw Resource

Aug 13, 2009

I'm running into a strange problem while reading from an InputStream on the Android platform. I'm not sure if this is an Android specific issue, or something I'm doing wrong in general.

The only thing that is Android specific is this call:

CODE:........

This returns an InputStream for a file from the Android assets. Anyways, here's where I run into the issue:

CODE:........

When the read() executes it throws an IOException. The weird thing is that if I do two sequential single byte reads (or any number of single byte reads), there is no exception. Ie, this works:

CODE:........

Any idea why two sequential single byte reads work but one call to read both at once throws an exception? The InputStream seems fine... is.available() returns over a million bytes (as it should).

Stack trace shows these lines just before the InputStream.read():

CODE:........

Changing the buffer size to a single byte still throws the error. It looks like the exception is only raised when reading into a byte array.

Android :: HttpPost Works With Wifi Not With Mobile

Jan 3, 2010

I'm trying to use HttpPost to send data from an android device to a server. It works great with a Wifi connection, but I get the IOException "The target server failed to respond" with a Mobile connection (3G, Edge, etc.). It doesn't seem to be a timeout problem (I set it to 90s). The use of HttpGet works perfectly with both Wifi and Mobile connection... Any idea of where the problem could come from?

Android :: HttpPost Not Works In Java Project

Nov 19, 2010

I've written some code for my Android device to login to a web site over https and parse some data out of the resulting pages. An HttpGet happens first to get some info needed for login, then an HttpPost to do the actual login process. The code below works great in a Java project within Eclipse which has the following Jar files on the build path: httpcore-4.1-beta2.jar, httpclient-4.1-alpha2.jar, httpmime-4.1-alpha2.jar, commons-logging-1.1.1.jar.

public static MyBean gatherData(String username, String password) {
MyBean myBean = new MyBean();
try {
HttpResponse response = doHttpGet(URL_PAGE_LOGIN, null, null);
System.out.println("Got login page");
String content = EntityUtils.toString(response.getEntity());
String token = ContentParser.getToken(content);
String cookie = getCookie(response);.......................

Android :: IOException Everytime Try To Upload Anything To Emulator

I'm using Windows 7 Ultimate 64 bit edition and Eclipse 3.5 with the Android plugin. Every time I create a new project and try to publish it, I get an error like this:

CODE:............

The emulator is working perfectly, adb can see it, I can even logcat from it, but it can't push or pull anything from it. Nothing appears in logcat to suggest the emulator even received any command. It doesn't matter if I have the Firewall on or off, or if I try invoking adb install to bypass the plugin. Nothing works even with a blank app.

Android :: HttpPost - Ssl And Error - Not Trusted Server Certificate

Feb 9, 2010

I want to use HttpPost over https/ssl. I get 'Not trusted server certificate' error. I've found a lot of posts, seems that many people have similar problems and I've found two suggestions: 1) Change server's certificate. Current certificate is self-signed as localhost.localdomain. Unfortunetly it's not my server and I cannot change the certificate. 2) Use HttpsUrlConnection instead of HttpClient. But I cannot use it because sometimes (when response's code is 401 or 403) I got IOException during getting response code or reading inputstream.

So I've found 3rd solution - use httpclient, when system throws excetpion 'not trusted server certificate' than display warning, inform user that certificate is not trusted and ask if he wants to add this one to the keystore (webbrowser works this way). But I've no idea how to get certificate from the server and add to keystore.

Android :: Issues With Httppost - Authentication Challenge Is Empty

Nov 3, 2010

I'm developing an Android app which needs to perform an HTTPPost to get a token back. Then use that token for subsequent calls. When I perform the initial call to get the token, it throws an exception: org.apache.http.auth.MalformedChallengeException: Authentication challenge is empty

Here is my code:...............

I googled "Authentication challenge is empty", and one this website: http://fmpwizard-scala.posterous.com/using-apache-httpclient-authenti... he had a similar problem. He determined that his web server requires preemptive authentication. Which I believe ours does too. I tried implementing what he did, and still, no dice.

I've hard coded the token in other requests, and I am able to perform HTTPGet calls.

What is the Authentication Challenge that I'm missing?
