How To Detect If Socket Is Closed By Remote Peer

Jul 11, 2012

I am writing a proxy in Android. I want to know, how one may detect if the server or client has closed its socket? I am using pre-NIO sockets. It should be noted that, the YouTube App will connect with my Proxy server (I have installed proxydroid) and then data will pass between YouTube App and Youtube Server through my proxy.

I have used read() method for reading. When I am reading (with read() ) as a client (from the server) if I get -1, does it mean that the server has closed the socket?

In the same way, If I am reading (with read()) from the client and get -1, does it mean that the client has closed the socket?What is the best way to detect if a remote peer has closed the socket or not?If I use methods like isInputShutdown() or isOutputShutdown() ?My main goal is read into a byte array until the remote peer has closed the socket?

Android :: Java Socket Not Throwing Exceptions On Dead Socket?

Jun 29, 2010

We have a simple client server architecture between our mobile device and our server both written in Java. An extremely simple ServerSocket and Socket implementation. However one problem is that when the client terminates abruptly (without closing the socket properly) the server does not know that it is disconnected. Furthermore, the server can continue to write to this socket without getting any exceptions. Why? According to documentation Java sockets should throw exceptions if you try to write to a socket that is not reachable on the other end!

Android :: Socket Programming - Java - Many Clients One Socket

Nov 12, 2009

Essentially Im trying to get many many java clients connect to a socket on my ColdFusion server (Using the Socket Gateway). However before i even start to code this, Im a little confused about sockets and their performance. First of all, are sockets meant for many(1000+) clients connecting to one socket (say port 2202) on one server? How is the performance if all there waiting for is basically a ping, or something such that when these clients receive this "ping" they can go get some new data.

Android :: How To SetRouting - And DoRouting Which To Select Endpoint Audio Device Is Implemented

May 14, 2009

I want to add one more endpoint audio device in android and am trying to modify the setRouting() functions to support the selection of the new added audio device. As far I traced, the doRouting() in class AudioHardwareOss should perform the audio endpoint device selection. However, donRouting() just returns NO_ERROR without any other functionalities. So, my question is where and how endpoint audio device selection is achieved.

Android :: Connecting Android Bluetooth Client Socket To Ubuntu Server Socket

Jul 15, 2010

I am writing an Android app that should exchange data to a server over Bluetooth, with the server side on a PC running Ubuntu, using the bluez library, in C (or C++).

My Android app fails (IOException) when I try to connect to my server socket on the PC.

Here is essentially what I in the java code (in Android, full eclipse project here: http://dl.dropbox.com/u/2968234/ThinBTClient.zip)

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

This throws IOException after a timeout of 10seconds or so.

On the server side (in Ubuntu 8.10), I basically set up a Bluetooth server socket, along the lines described in the example bluez/sdp-register.c

Down below is my C++ program. To compile it do

g++ -I/usr/include/glib-2.0/ -I/usr/lib/glib-2.0/include -o bt_server bt_server.cpp -lbluetooth

I can do the reverse succesfully, i.e. create a server socket in Android and connect from Linux, however this is not what I want to do!

I think either the problem has to do with my config of Ubuntu.

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

General :: Mount Operation Not Supported On Transport Endpoint

Apr 29, 2014

I've created a single primary Ext2 partition in my phone's external SD card but Android refuses to mount it automatically. Whenever I attempted to mount it manually it kept throwing the error "mount operation not supported on transport endpoint".

How can I mount it?

Using (SlimKat) Android 4.4.2.

EDIT: I'm now able to mount it only manually but have to specify ext4 as its filesystem -- why and will it make a difference since ext2 is non-journalled? Also, I tried adding a mount entry in /fstab.smdk4x12 but it was deleted upon reboot; does this mean no manual entries are allowed in that file and I will instead have to hack my own /init-xx.rc file to manually mount the partition at boot time?

Android :: WiFi Network - Password Invalid After Disconnected

Apr 20, 2010

I have a WiFi network at work and it requires a New password generated from a secure token each time when I try to re-connect. Since Android WiFi setting remembers the password, if it try to re-connect using the saved password (it becomes invalid after disconnected), my secure token become invalid. If I remember to remove the connection each time after I disconnect, I can enter new password when the connection is discovered as a new connection again. The problem is what if I forget. In addition it is inconvenient. Do you know any Android application supports remove a chosen WiFi connection password each time the connection is lost?

Android :: WiFi Disconnected When Phone In Sleep Mode?

Oct 6, 2010

I have a service which polls a server at certain intervals. I use an AlarmManager and a BroadcastReceiver to start the service. My problem is that after a certain duration, even though the WiFi is still enabled, but for some reason, my application can't contact the server. I get an "Unreachable network" error. Note that I've already acquired a partial wake lock as well as a wifilock. Here's my code for the BroadcastReceiver.

public class ServiceAlarmBroadcastReceiver extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
WakeLock wakeLock = null; WifiLock wifiLock = null;
try { PowerManager pm = (PowerManager) context .getSystemService(Context.POWER_SERVICE);
// acquire a WakeLock to keep the CPU running
wakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "MyWakeLock");
if(!wakeLock.isHeld()){ wakeLock.acquire();
} Log.i("ServiceAlarmBroadcastReceiver", "WakeLock acquired!");
WifiManager wm = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
wifiLock = wm.createWifiLock(WifiManager.WIFI_MODE_FULL , "MyWifiLock");
if(!wifiLock.isHeld()){ wifiLock.acquire();
} Log.i("ServiceAlarmBroadcastReceiver", "WifiLock acquired!");
context.startService(new Intent(context, ThePollerService.class));
} finally { // release the WakeLock to allow CPU to sleep
if (wakeLock != null) { if (wakeLock.isHeld()) {
wakeLock.release(); Log.i("ServiceAlarmBroadcastReceiver", "WakeLock released!");
} } // release the WifiLock if (wifiLock != null) { if (wifiLock.isHeld()) { wifiLock.release();
Log.i("ServiceAlarmBroadcastReceiver", "WiFi Lock released!"); } } } } }

Samsung Epic 4G :: 4G Network Disconnected

Nov 7, 2010

I live in nyc where according to sprints coverage map I'm located in a dark blue area where 4g is supposed to be working even indoors. However, when I try to connect to 4g indoors my phone always tells me "4g network disconnected". The only time I get 4g is if I'm outdoors and even then it sometimes disconnects after a few minutes. So is this what we have been waiting for? For a 4g speed that only works if you're outside? I'm wondering if this is only in NYC or in all other places that officially have 4g? I can't believe that I'm paying 10 dollars extra for a service which I won't be able to use 90% of the time!

HTC Hero :: USB Connected And Mounted But Sync Disconnected

Jan 14, 2010

I have done a search and found problems of people cannot mount and are not connected. However, my prob is different. This is my second PC to attempt with same problem. I dl HTC Sync and connect with USB cable that came with phone. I get the USB icon on the top of Hero but HTC Sync says disconnected. When I bring down the USB icon and press Mount I get a "Removable Disk (E" popup. The options at this point are: Copy pictures to folders, Use slide show of images, Print the Pictures, Copy Disc, Play, Play Video Files, Open Folder to View Files, Take No Action. This tells me that the PC is reading my phone, however, HTC still says disconnected. Do I select one of these options in order to be connected on Sync? My goal is to update the firmware.

Motorola Droid :: Mobile Network Disconnected

Oct 11, 2010

I have a Motorola Droid that I FULLY FLASHED(all the features) to Metro PCS about 4 weeks ago and it hasn't had any problems until now. I know Metro Flashed phones are only supposed to have all the features but just talk and text but come on,I got it specially programmed you know for full features.what's the point in having an awesome state of the art phone if you can't do crap with it? For some odd reason since yesterday morning,the phone's internet connection has been off.There is no icon of 1x or 3g,etc.In settings it says Mobile Network Connecting and later it says it has disconnected. WHat should I do?Believe it or not,I called metro and they kept on giving me the run-around.I'm guessing I wasn't going to get anything out of them because this flashing thing is kind of 'under the counter'.Should I call the programmer about this problem?Factory Default/Reset? I actually love my phone this time around.I use the internet a lot and this is like killing me.I feel 'blind'.lol.Plus I got this new Assassin's Creed game I need to install. I don't know what's wrong. :-/ :-S I know I have my Wifi turned off btw.

At home i've noticed that even though I have wifi on, it'll drain 15-20% of my battery over night (8 hours). When I turn the display on it'll show that there's no wifi connection available, but wifi is still enabled. After i turn the display on, it'll quickly connect to my wifi. Is this normal? How do i make it stay connected to my home wifi when the display is off/phone is in standby?

Sprint HTC Hero :: Bluetooth Headset Disconnected

Jan 4, 2010

Two issues I would appreciate help with.

1. How do I stop this message? "Bluetooth Headset Disconnected" I get it very often on my Hero. I have the phone paired with my 2009 Toyota, and leave the Bluetooth turned on on the phone all the time, so I don't have to remember to do that each time I enter or exit the car. I have also paired my phone with my wife's car, but she uses her phone with her car most of the time. Is there a way to stop this message? It has been hours today since I used my car, and I continue to see this message pop up on the phone. It does go away after a few seconds, but it is annoying.

2. When I go to Bluetooth settings, there are 3 devices shown, CAR MULTIMEDIA, CAR M_MEDIA, and HANDS FREE. I think our two cars are called CAR MULTIMEDIA and CAR M_MEDIA, and another one that I once paired with a Garmin GPS called "HANDS FREE". Is there any way to delete that 3rd device? And is this causing the above message?

I have restarted the phone, pulled the battery,put my sim card in my brothers captivate and it works fine on his. After the phone restarts the 3G icon will appear for maybe 1 minute and I connect for that short time then it disappears and no more 3G. If I switch to wifi I can connect just fine.

Samsung Galaxy S :: USB Connected Notification Stays On / After USB Is Disconnected

Aug 20, 2010

The "USB Connected" notification stays on after the USB is disconnected, there's no way to evict it other than a reboot but now will reboot only if USB is reconnected to PC or Charger.I was so pleased by my new Galaxy S cell 3 days ago after a week of exploring and managing to get the best carrier and plan for this bright Samsung Smartphone. Then, the day after it lockup, but removing the battery for few seconds then replacing it back fixed that problem for that day. The following day been great too up the second lockup at night and this time, removing temporarily the battery did not permit to have the cell working anymore.So today I have been trying all day to determine under what condition these lockups occur. During those tests, I've first determined that during charging or during USB PC connection, I could repower up the Galaxy S. Then the cell could work for long period of time if connected to USB PC or power supply, but when I remove the USB cable, the firmware fail to detect that there is no more USB connection and start to flash every couple of seconds the message "USB connected" replacing the status bar at the top of the screen.

Then after several minutes, the cell freeze, and only by removing for few seconds the battery and then plugging the charger again, will permit to successfully power up the phone.I have of course made a Hard Reset to Factory Default, to no avail, during those tests. I think it's a hardware malfunctioning around the USB Port section. The connector look good seen with loop and both USB cable seem ok.If it's corrected by an update, I wonder if I'll be able to re-flash under this condition.
