Connecting App Android To PC Server
Apr 10, 2013
I'm trying to connect my Android app to a PC server using Socket. Unforunately, the PC server doesn't receive any connection request from the app (there's no connection between them). I'm running the app in android emulator.
I've seen many tutorials and discussions in the internet about this problem and I fellow them literally, but still having the same problem that I mentioned above. the android app is running on eclipse emulator and the PC server on netbeans
the PC server source code:
public class server{
ServerSocket server;
public server() {
try
[code]...

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.

I have a hosting account at godaddy ruinning Linux. Is has MySQL. I am creating a J2ME application that runs on android and I was wondering if there is any simpler way to connect from j2me application to my MySQL server?
Is it required to install anything at my server? which I cannot do because of the shared account. Any way to just open the connection, update some data in the MySQL from j2me application?

Using appbrain on my PC seems to work fine when I'm not logged in. When I do log in and try to click on an app I get this error message:
"Error: Server Error The server encountered an error and could not complete your request. If the problem persists, please report your problem and mention this error message and the query that caused it."
Anyone else have this issue when using Appbrain on their pc?
Well, It looks like I solved the problem. I just deleted my account and created it again and it's fixed (for now).

I have a widcomm example BluChat "WIDCOMM SDK RFComm Service" running on my PC with an USB dongle (BT-2400P). I would like to connect this chat from my HTC Desire. So I stared with the Java example http://developer.android.com/resources/samples/BluetoothChat/index.html. This is also using BT RFComm. If I'm using my HTC as a server it work's fine, but I would like to use my PC as a server. Then .connect() comes back with "Service Discovery Failure".
I have modified the UUID string in the Java example to match the PC-application

What about handheld devices (PDAs, Smartphones, etc)? For Windows Mobile devices, there is SecureW2 for Windows Mobile. For iPhone, see our iPhone Web page. Currently, we know of no method for connecting Palm, Blackberry, or Nokia devices that are not running Windows Mobile to the UIC-Wireless network.

When at work I switch on my Wifi so that I don't use my plan data unnecessarily. When I do that it switches off 3G (which is good) but then most of my apps don't seem to connect - eg Facebook, Market, GMail, etc... So are most apps not able to operate on Wifi alone? Is there some config I need to change to make the apps be able to switch easily between 3G and Wifi connectivity?

I need to test my android app 24h day and I have 3 ubuntu boxes to do it. I would like to connect my development system (MOTODEV Studio 1.3) to a Remote Device.
Well, the interface ask me about ip for machine and port to connect to.
But it doesn't. I found that the adb sever on remote seems not to listen to external ports, only internal loopback, making connections machine-machine impossible.
Could it be true? If so, why there is a section on Device to connect to Android Remote Device on MOTODEV Studio?
I've found an explanation and a workaround in this post (http://rxwen.blogspot.com/2009/11/adb-for-remote-connections.html) but it seems complicated and post's links doesn't work, so I'm confused whether there is a solution to do that.

I just got a Android Eris and plugged the USB cord into my computer and phone, it looked like it was going to work, then said it needed to install a file from the cd (I have no idea what that means). I am at school right now and forgot the name of the file it needed, but I have no idea how to do this. I want to tether my phone to the computer with PDAnet but can't even get my phone connected to the computer. I also want to put music on the phone. I am on Windows XP. If you need more info, I can get it when I get home from school. Just hoping there is an easy step I am overlooking.
