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...
Android :: How Http URL Connection Work?
Jan 18, 2010I 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 RelatedAndroid :: Retrying Http Connection
Oct 14, 2010I'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?

Android :: Way To Make HTTP Connection Using GSM Network?

View 2 Replies View RelatedAndroid :: Http Chunked Response - Connection Reset
Sep 6, 2010I'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?

Samsung I7500 :: Wifi Connection Lost After Screen Lock And Can't Regain Connection After Unlock
Sep 7, 2009If my screen locks while I have a wifi connection, then the connection is lost when I unlock the phone.First, is this perhaps deliberate, to save power? Also, either way, when I unlock the screen and go into wifi settings, I see that the phone is trying to make a wifi connection, but it never succeeds, even though it's my home network and I'm in the same room as the router. It just states 'Obtaining address.
View 10 Replies View RelatedAsyncTask Force Close Errors / HTTP Request To MySQL Database
Aug 22, 2012I'm trying to connect my app to a MySQL database to retrieve data. Obviously I have to do this in a new thread hence why I chose AsyncTask, something I'm new to.
I have included Toasts to tell me if there are problems when trying to carry out any part of it. However these toasts are not showing on the UI thread. I tested this out by turning off the server my SQL database is on so that it could trip the first toast. It didn't show it though and instead it gave me a force close error. When my server is running I have no issues and although I haven't coded the bit to retrieve data yet the code below does connect to my database and at least lets me view the page "CurrentSeasonDrivers".
Here is my code and the logcat showing the errors below that:
package com.android.history;
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.ArrayList;
[code]....
All I want it to do is show a toast if the application cannot connect to the server instead of force closing.

View 3 Replies View RelatedAndroid :: Doing Broadcasts With HTTP Server Push Over WiFi?
Apr 2, 2010We are designing a system with a PC base station and 100 Android mobiles communicating over WiFi. They will use XLM-RPC as the method of mobile to base station communication. However, sometimes the base station needs to broadcast a message to all mobiles. Should we use "http server push" for this, i.e., have the base station leave the connections open to all the mobiles? Is there a better way? Publish-subscribe is possible, but doesn't seem mature on Android yet.

WiFi sees the network, says "Connecting", comes up "Failed to connect", "Scanning" and loops on that sequence. I know the router's working because this laptop is using it right now
Nexus :: Data Connection Force-restarting
Nov 28, 2010Whenever I use the data connection, the phone crashes and it reboots.Sometimes it happens some minutes after browsing, other times it happens once the packets start flowing, and other times instantly just after a reboot, which forces another reboot again.Some applications started crashing too, mostly games.Since a couple of days ago I've been getting some restarts just browsing on the settings too.I did a factory reset which proved unsuccessful, and I've been wondering how to do a full wipe of the system to reinstall Android and hope that fixes it. However, I fear it could be a bad memory block or some hardware problem that's causing the crashes.AFAIK, there haven't been any incidents (drops, spills, etc), the problem just started happening and has increased in frequency.Also, could someone guide me to how do I reinstall Froyo?

Aug 4, 2010This is a newbie question: I've had my Droid X for only four days so far, but love it. While at home, I sometimes have problems connecting to a network. I think the problem is that 3G is not as strong here, but I have a good WiFi network. Is it possible to have the phone use WiFi as the first option so I will keep the connection even if 3G is weak? Or is my problem something else?

Jun 23, 2010We live in the sticks and we get a bit of a G connection here, maybe 1 bar if we are lucky.
What I've found is that my samsung galaxy S with android 2.1 uses the G connection no matter how bad it is despite a perfectly good wifi connection here.
It's only if the G cononection completely drops and the red no entry sign appears to show us that the carrier isn't available at all that suddenly the phone uses wifi.
Is there a way to change the provider order so that the phone will use wifi before g/3g ?

Aug 21, 2011I'm new here and I'm using a doixanh ROM, GingerDX (but I already used Froyobread). So, some time ago I had a problem...I couldn't connect my device (Sony Ericsson Xperia X8) to wifi.
What I did? I full wiped the phone...and that fixed the wifi issue. But now I have the same problem...I can't connect my phone to wifi anymore!
I could do another full wipe, but this problem would just appear again and again...I googled for some fixes and I found some answers...one of the solutions would be deleting one file (dhct or something) from the phone...the problem is: I don't have that file...
Another (on a youtube video) to download an "hot fix" package with 3 files and place them on the phone...but the link that he gave is broken and I couldn't find those files on the internet.
Like wifi, my phone's GPS doesn't work too.
