Android :: Network Access With HttpClient Using AsyncTask

Mar 16, 2010

I am trying to use a certain wrapper of HttpClient, called HTTPRequestHelper with an associated responseHandler as the basic class for my wrapper to a web service which is implemented as a singleton.

HTTPRequestHelper and samples of usage are described in chapter 6 of "Unlocking Android" published by Manning.

My problem is that invoking both the helper and the handler from a thread started on the main UI thread (either from an AsyncTask or directly) works only sporadically.

Here is the basic setup.

public class APIService { private ArrayList<Something> myThing;

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

Android :: Fetching Data - Responsebody - HttpClient In An AsyncTask And Returning Data

Mar 16, 2010

How I'm able to do what I've written in the topic. I've looked through many tutorials on AsyncTask but I can't get it to work. I have a little form (EditText) that will take what the user inputs there and make it to a url query for the application to lookup and then display the results.

What I think would seem to work is something like this: In my main activity i have a string called responseBody. Then the user clicks on the search button it will go to my search function and from there call the GrabUrl method with the url which will start the asyncdata and when that process is finished the onPostExecute method will use the function activity.this.setResponseBody(content).

This is what my code looks like simpliefied with the most important parts (I think).

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 :: AsyncTask And Simultaneous Network Downloads

Jan 28, 2010

I am performing several https posts and http downloads from two different servers using AsyncTasks. The connections are fairly quick but I'm surprised to see that they are running synchronously instead of in parallel.

To be more explicit, here is pseudo-code for what's happening when I initiate a call to AsyncTask1():

Android :: Instance Variable Of Activity Not Being Set OnPostExecute Of AsyncTask - Return Data From AsyncTask

Jul 28, 2010

I'm trying to figure out the correct way to create an AsyncTask to retrieve some data from the internet and then to take that data and bundle it up in an Intent and pass it to a new activity(A list display). So in the first activity I just have an EditText and Button. In the event of an OnClick the task should be called and when it is finished the data should be bundled inside an Intent and passed to the next Activity. The problem is when I take the results from onPostExecute and set them to an instance variable of the main activity, that instance variable is still null when the task is complete. Here is the barebones version of the code:

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

When I debug the application I see onPostExecute does contain a valid PlacesList full of results, so why is the instance variable places set to null after the task is executed? I am going about "returning data" from an AsyncTask incorrectly?

Android :: Network Access Is Slow In Emulator

Aug 5, 2010

I've noticed very poor performance in the emulator (1.6 and 2.1) when trying to complete the forth statement below. It will take 5+ minutes running in the emulator. Interestingly, when I debug on my phone it's not nearly as bad at maybe a minute or so, but still not great. Running the app on my phone without debugging yields great performance (seconds). URL url = new URL(CommonProperties.BASE_SERVICE_URL + "param=1"); DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); DocumentBuilder builder = factory.newDocumentBuilder(); Document dom = builder.parse(url.openConnection(). getInputStream()); is there something I can do to speed up network access while using the emulator? Has anyone noticed anything similar?

Android :: Network Connections / Access Points

Jul 16, 2010

I have some code that uses a network connection. I create a connection by calling openConnection() on a URL object. Is there any documentation that explains how this process works? Which access point is being used? When that access point becomes invalid, will it automatically switch to another accespoint? etc. I would like to use only WiFi access points and otherwise fail even tho 3G or GPRS could be available, is that possible?

Android :: Network Access When Phone Sleep

Mar 21, 2010

I'm using a combination of alarm (set with AlarmManager) and background service to periodically synchronize data in my application. The only problem I have is that when sleep policy terminates Wi-Fi connection the synchronization no longer works. Is there a way to "wake up" the Wi-Fi connection that has been put to sleep? GMail somehow manages to do that because it notifies me about new e-mail even if the phone entered sleep mode.

Android :: How To Make Applications To Use Only Network Access Point?

Feb 3, 2010

Is there a way to force all my requests to be made through my APN and not through wifi, without having to disable WiFi? I want to know if it is possible for my application to use exclusively the network access point. I'm already able to set the default network APN and to use it but for this I have to disable the Wifi first.

General :: Tethering Setup - No Access To Network

May 21, 2013

I have a problem ( but i think that's more my setup problem).

My phone: i9100g
Rom tested: CM10, SlimBean v5

Neither wifi/usb tethering are working, when I connect my phone to pc it tells me "no access to network".

I'm having same problem with different roms,so i think that i should change my settings,and it's not a bug of the rom. My default APN at "APN Type" was "default,supl". i Have changed to "default,supl,dun" but nothing,tethering doesn't work.

Samsung Captivate :: Access Forbidden For All Webpages - AT&T 3G Network

Oct 25, 2010

So I got my Captivate this weekend, and have been using it on my WiFi at the apartment and everything is working fine. But today I went to work, and now any webpage I try to access just shows up as a blank white page with the words "Access Forbidden". Other apps work just fine, I just can't visit any webpages. I'm definitely connected to 3G, with a strong signal strength. I read in one thread that clearing APN proxy settings solved this problem for them, but I can't find any way to edit the APN settings on my phone (can only view them). I read another thread that this happens to people who switch over from an IPhone; only problem is, I've never owned an IPhone. I'm contemplating giving AT&T customer support a call, but wanted to check here first to see if anyone else is having this problem/has a fix. Here are my APN settings in case this clears anything up:

Name: ATT WAP
APN: wap.cingular
Proxy: wireless.cingular.com
Port: 80
Username: Not Set
Password: Not Set
Server: Not Set
MMSC: http://mmsc.cingular.com
MMS proxy: wireless.cingular.com
MMS port: 80
MCC: 310
MNC: 410
Authentication Type: None
APN type: internet + mms

These are the default phone settings and it won't let me change any of them, although it will let me create a new APN and edit the settings of that. It seems odd that the default APN is Cingular...that is the service I had years ago, but it merged with AT&T a while back.

HTC Desire :: Phone Stopped Getting Internet Access / Got Network Error

Nov 1, 2010

I am on a debranded Orange handset running Android 2.2. Had the phone for around 4 months without issue. I went to London last weekend and started noticing problems with the mobile internet. I was largely relying on it to get me around but the mobile internet is playing up. Even if I have H or 3G signal, my phone has suddenly stopped getting internet access or i get network errors. Nothing has changed on my handset and I usually get good signal wherever I go. I'm currently in work where I always get 3G symbol. I have the 3G symbol now with both arrows animated yet my web browser won't load anything and the market place just says I have no network access. Could this be something to do with the Orange/T-Mobile merge? Or has my phone died on me?

Are there any easy apps to encrypt myself while on it? I see SSH Tunnel and Connectbot, but I don't have a server.
