Android :: App And Website Server Connection
Sep 13, 2010
I want to create a browser to view as an administration.My project is about ferry booking using an android phone. The application is connected to the server. The ferry timing and other info are retrieved via server connection. The database is currently in Microsoft Access.My question is how do I create a browser to view data (e.g view users, delete users, create notification etc etc)? I want to create so called a 'website' that have access to the same database as the android application. Do I use Microsoft Visual Studio? How am I suppose to create a connection to Microsoft Access so that I can edit the database appropriately?

I have been trying to setup a Droid to Droid 3G connection. I can confirm that all works great in wifi mode. The Droid can make connection requests (Http, Telnet, raw sockets) in 3G, but I cannot get the Droid to accept a socket connection in 3G mode. I was told by Verizon that a special license may be needed to accept socket connection requests and they would send me some information. So far none has been received. If anyone knows how to program the Droid to accept socket connection requests over 3G, please respond. Also if anyone knows why this not allowed please respond.

I wrote this:
HttpsURLConnection con = (HttpsURLConnection) new URL ("Here my server URL is provided")
openConnection(); con.setDoOutput(true); con.setDoInput(true); con.connect();//
At this point I am getting error saying Java.net.SocketException:permission denied..
Actually I am sending request to server after getting request in XML format I want parse using
xr.parse(new InputSource("URL"));
But its giving error at con.connect(); only. And I have added Internet permission in manifest file.

I am playing around a bit with peer-to-peer communication with android devices.I have written a basic program that creates a listening ServerSocket on each phone using the application. Using the application you can also connect to other devices that is listening, by connecting to the remote ServerSocket. Nothing strange about that.My problem is that it seems that the listening port is not open for connection on different devices. I can connect to my HTC Desire, works like a charm. But connecting to a HTC Hero I get timeout, same if I try to connect to the emulator. But connection FROM the emulator to the Desire and FROM the Hero to the Desire works like a charm. Whats up with this? No security apps is installed and both devices(and the emulator) is running 2.1.

I have set up a VPN server on OSX Lion Server edition.It is using l2tp with preshared key and username/password for login. i(beep) works fine and connects. Laptop works fine and can connect.But...
1. When Iam on local network (same IP segment) I can connect using Android native l2tp VPN connection setup with PSK and user/pass.
2. When I try to connect from external (3G or other WiFi net) I am unable to connect.
3. When I enabe native tether on Android device, and connect i(beep) to the Android AP, I still am able to connect from i(beep).
These three steps tells me it is not a carrier issue, and possibly an Android issue.Kinda like the l2tp connection for security, and also Lion natively does not supply pptp connection.

I have to create an app that allows other devices to connect to my android terminal via wifi, without access point, so my device should become an access point to host their connections. i don't have to share the internet connection with them, just have to make them connect directly to me, then they send a UDP packet, and I have to read it, so on my device will have to be an UDP server after the connection creation. how to manage wifi? any step to follow? my android version is 4.0.3

I have a question about Google Talk. Is there any way to keep it from disconnecting after a while after the screen has been turned off? I have "always-on mobile data" active but after a minute or so after turning the screen of Google Talk disconnects and I don't receive any messages until I manually turn on the screen and wait for it to reconnect and retrieve the new messages.Just to note it doesn't actually show the splash screen saying signing into Google Talk it just says "Lost connection to server. Messages will be sent when online" bellow the most recent message.

I have exchange set up on my Droid through the email program that comes with the phone.. Its been working fine until this weekend, really. 3 separate times, it's failed to load my inbox or sync new messages, and it pops up with the unable to open connection to server message.Ive quadruple checked all of my settings, removed my account, re-added my account, refreshed it, and still, it wont sync my inbox and it still shows that message. I even tried installing touchdown, and touchdown wouldnt sync my email either? I didnt like how it kept my contacts all separate from my gmail contacts, so I went ahead and uninstalled it. I REALLY just want to use the regular exchange email program..But get this, I am able to sync my sent mail though, and Im able to SEND email messages, just not receive them.
We have our own exchange server for our company, and we have 4 other people in our office running exchange on their phones, (2 Motorola Droids, 1 Droid X, and an HTC 6800...) Nobody else is having issues with their phones syncing their email so I know this isnt an exchange issue, but a phone issue instead.Ive run an update (just the *228) on my phone, reset it like 3 times, killed all the apps, and it still wont sync my inbox (just my sent mail..) And again, it'll send email but wont receive it.I know calling or going into a verizon store will be a waste of time.

I have a question regarding my new HTC Hero. I bought an unlocked one and are currently using it with Tmobile. My internet works but I am unable to go to the market to get applications. Does anyone know what to do? I already called and spoke to TMobile but they were unable to help me. The message I get is: Can't establish reliable data connection to server.

I am on the Nexus 5.I have already looked up about this problem online, but the fixes for this seems to be either a hard reset, a factory reset, or the YouTube trick, where one signs into their gmail through YouTube and fixes this issue.
I have attempted all three of these things, but I still can't add my gmail account. The "Can't connect to server" message still pops, even when trying to sign in through the YouTube app.

I have a Motorola Atrix2, running Android 2.3.6 on AT&T. I have used Google Talk since getting the phone last December, but for the past week have had trouble.
When I wake the phone I find that I am no longer signed into Talk. My contact list is subdued in grey, a notice appears at the bottom of my chat window saying that the connection with the server has been lost, and my 4G icon has gone from blue to white indicating that I no longer am connected to Google.
I haven't done anything to the phone / settings to cause this. I've tried many things to fix this including: rebooting, hard booting, force stop the application and clearing it's data (cache is always empty), and replacing the SIM. Needless to say none of these steps have worked. I have not tried a factory reset as I have read elsewhere of people trying this with no luck.
As far as I have been able to tell, this problem only happens when connected to my service plan, I have never noticed this happening when hooked onto WI-FI
Having searched online all I can find that might be at fault is the version of Android (the phone originally had 2.3.4 but was upgraded several months ago), and the fact that AT&T has recently upgraded to "true 4G LTE" in my area. I have no idea if either of these are actually the cause of my problem.
Google Talk is one of my two main means of communication and I really need this resolved.

I use an LG Optimus L4 II (e445). I rooted it but then decided I had too much on it and decided to restore to factory settings. It all worked fine. However, when I got to the Google Account sign in page, it gave me the "couldn't establish a reliable connection to the server" error message. I followed every single tutorial I could find online as to how to solve this. None of them worked. Eventually, I re-rooted it (using VRoot) and managed to download an apk of ES file explorer and locate the hosts file. This had one line that shouldn't have been there:
[URL]
From what I can make out, this is the address of google's sign in servers. So somehow (I suspect malware/dodgy rooting program?) my hosts file has been edited to stop me logging into google. Restoring the device does nothing, neither does unrooting/rerooting. When I open up the file in ES (when rooted) and edit out the bad lines, I can't save for some reason- I think the /system folder is write protected.
So I tried to make the /system folder writeable. I used the android sdk to do this (mount -o command) but this did not do anything. I downloaded the mount /system apk and installed that, it did not work either. I tried /pull and /push on the hosts file to edit it and send it back using the apk. I could successfully pull and edit it, but it would not let me push it back. I can effectively not use my phone- I can't use most apps and can't download any.

I recently downloaded K9, having read on here what a good email program it is. I can't get the thing to work with my Yahoo.co.uk account. It's Pop 3. The account works ok with the standard HTC email program, but when I try to set it up using K9, I get "Setup could not finish Cannot connect to server (Unable to open connection to POP server)." I've googled it, I tried setting it up without using wifi, and tried changing settings to IMAP and port numbers, but just can't get anywhere with it.

I'm trying to set up a VPN connection between a Linux Mint 10 PC (server) and a Nexus 7 (client).
All I'm getting so far is a "Connecting" status from the Nexus 7, followed after a few seconds by a "Disconnected" one.
As it is my first attempt at setting up a VPN (both on the server and client sides) I was wondering if there was a log file generated by Android on the Nexus that would give me a clue as to where I'm going wrong.
A similar file on the server side

"Unable to open connection to server." That's the message I'm getting from my Droid every time I try to set up a connection to my web hosts SMTP server using IMAP. The settings I put in the Droid work fine on my laptop and on my blackberry.
I've tries using ports 25, 1025, 465 and 587. I even tried 143 and 585. Anyone have any clue why this is happening? Anyone else having trouble with SMTP/IMAP connections to their email server? Right now I can't send emails from the Droid and that's a HUGE problem.

I have a Samsung i7500 (Galaxy).Originally, it had Android 1.5 installed, but I could not enter the Google Market with my google account and got this message: "Can't establish a reliable data connection to the server".I read here and across the web I should Factory-reset my phone, but it did not work.So I upgraded the firmware to Android 2.1 using this guide: How to Mustymod It worked, and now the phone had Android 2.1 installed, but I still cannot access the Google Market with my Google account. This time I did a factory-reset (Settings -> Privacy -> Factory reset) and also followed this guide to delete the provider-settings (eventually I removed the whole /data/data/com.android.providers.settings/ directory and not only that file.
