Android :: Sending Data To Server When Device Connected To Internet

Feb 18, 2010

My app needs to send some data to a server when the device is connected. I have been reading about native Android Broadcast actions. I was willing to find a way to use one as gmail does when the device connects to the Internet. (The "loading" icon on the top while it syncs mails) Is it ACTION_SYNC what I am looking for? If not, how does gmail knows when the device connects to internet?

Android :: To Find A List Of Connected Server In Device?

Jun 30, 2010

Programmability i want monitor IP ever connected to my Adnroid device. My initial thought is i can write a background service which will run tcpdump command and forward its output to inputStream. By putting any regular expression i can retrieve list of connected IP to my device.I think that would be bulky to continually run command like tcpdump.

Android :: Way To Get Virtual Device's Browser Connected Internet?

Oct 15, 2010

When running a virtual device, how do I get it connected to the internet? When I check the settings of the Android SDK and AVD Manager, it knows about my proxy, but when I actually run a virtual device, the browser won't even bring up the Google home page. Instead, I get the dialog box: Data Connectivity Problem 'The server failed to communicate. Try again later.' and the browser displays 'Web page not available'.

Sending Message From Android Device To PC (computer) Using Internet Connection

Nov 11, 2012

I am creating an Android application. This application should send message to computer via internet and Wifi (check whether if the device is using internet). The main function is by pressing on a button in Android device a message should go to computer via internet (I don't know, but I think it should be with UDP). I know that I need to set the server for computer and write down IP and port to the android app code. I don't have any clue how to do it. I kinda need to create a computer (windows 7) server receiver, which would receive messages. I am using Eclipse Android SDK

Feb 19, 2009

I have a newbie question which is puzzling me regarding using Intents to start a new Activity but passing some data with the Intent for the new Activity to use.

Android :: Application Goes To Background Still Continue Working (sending / Getting Data From Internet)?

Oct 19, 2010

my application is not a service, it's a normal application, with some windows and some stuff. i dont wanna make it a service cos is too munch complicated and i prefeer to avoid it then, if my application is not a service, when it goes to background (home key pressed for example), it continues working (sending/getting data from internet)? i ask this because i read this on a developer guide tutorial: "Because an Activity can perform actions only while it is active and in focus, you should create your status bar notifications from a Service"

HTC Desire :: Connected To 3g - H - But Will Not Sync Email Or Allow Internet Browser - Data Connectivity Problem

Oct 8, 2010

The H symbol is displayed at the top of the screen and the arrows occasionally flash. The 'up arrow' flashes more often than the 'down arrow'. I have at least 2-4 bars reception.

However when I try to browse there is a 'data connectivity problem' and websites will not load. None of my apps, gmail, facebook etc will sync.

I am on t-mobile.

Fixes I have tried:

- turn on/off
- APN settings check
- Airplane mode

Have spent hours looking at other 3g threads, but have not found an identical problem. My phone says im connected to 3g ('H'), but will not update email or let me access websites on the browser.

Android :: Best Approach To Send Data From Server To Android Device

Jan 16, 2010

I am developing an Android app that needs to communicate bi-directionally with a server. By that, I mean either the server or the device can send a message at any time, with an arbitrary amount of time in between messages. Sending data from the device to the server is a common and I think well understood task, but I'm not as sure what the best approach is to go in the opposite direction from the server to the device.

I think having the device periodically poll the server may be a bad idea due to latency and the drain on the battery, but I'd be willing to consider this option. My plan at the moment is to send text messages from the server via an email-to-SMS bridge, and to have my app run a service to receive and handle these messages.

The question I have is if there are any best practices for this scenario, and if using text messages has some downsides that I have failed to consider. For the sake of this question, I want to assume that users have an unlimited text data plan, so paying per text won't be an issue.

I wish to send a list containing objects from server to client and vice versa through httpurlconnection. Elaborating the same, the list contains a set of objects which is defined both in the server and the client. Its just that the server queries a database and sends the object to the client which collects the same and displays it to the user.

Android :: Sending / Receiving Java Objects To Server

Sep 23, 2009

I have a Tomcat Server in front of a Servlet that gets/stores information in a MySQL Database. My Android application needs to get/ put information on to this server. I control both ends of the communication, so I've basically been exploring the "best" way to send information back and forth. So far, I've tried Jackson for JSON and the native Java Serialization packages. My object is relatively complex and completely serializable.I have no desire to write a "custom" guy at all, as I doubt I'd actually be able to improve on most of the packages.So with that being said, are there any other strategies/packages I should try to get information to/from my server?

HTC Hero :: Mobile Internet Always Connected?

Oct 2, 2009

I just bought a Hero today, and it looks like if it's always connected to mobile internet. The "E" icon is always there. What does that mean? I would prefer my HTC to connect only periodically. For example every 15 minutes to check my emails and sync my calendar. Is that possible? I think the battery life would much be better if we could do that, and I personally don't need my mobile phone to be connected to the internet 24 hours a day!

Nexus :: Connected To Hotspot But No Internet

Jul 17, 2010

First of all i got the Nexus 1, with stock 2.2 FRF91. my phone has an internet connection by itself (i always have the 3g icon and ability to browse the net at all times - both with or without the hotspot on). i also have a laptop running win7 32bit which connects to my wireless router with no problem. i tried setting up wifi hotspot on my nexus (both opened and secured - same result) then connecting with my laptop, it connects fine but then win says it has no internet connection (also when opening the "network and sharing center" it shows that the connection between the laptop and phone is ok, but phone-internet is broken). also, im not sure if that is related, but i tried connecting the desktop computer (win7 32bit) with usb tethering. my desktop has the nexus drivers installed (i am using adb commands here and there with no problem) again, it is connected and the pc is saying something about a "remote internet device" but no internet connection!

Samsung Galaxy S :: Using Internet When Not Connected To WiFi

Nov 20, 2010

I recently purchased a GTI-i9000. GPS on it is terrible and I have ready many forums with other users experiencing the same problems. I was thinking, and wanted to clear up a cloudy understanding. On my previous phone (iPhone 3G), when I was not connected to WiFi, I was still able to browse webpages etc, albeit slowly. Is that called GPRS? The form of data?

On my Galaxy, I cannot do this at all. If I am not connected to a WiFi connection, I have 0 internet. I'm just wondering if this is the cause of my dodgy GPS. Is there a setting i need to change or does the SGS not do internet if you're not connected to WiFi. I live in Australia if that helps at all.

Sony Ericsson Xperia X10 :: Connecting To Internet Via PC - When Connected By USB

Oct 28, 2010

I have a Xperia X10, great phone ! but some issues.

1) It seems to use loads of data even when i am not actively using the phone, and i have disabled google's background data setting. I would stop using the phone with the 3g connection on and my NetCounter app would say 2,5mb used , i would sleep and wake up and it would note 23mb used for instance. Does this phone send background info to SE and Google over and above what we can control in the settings. As i live in South Africa , our internet browsing cost are high even via 3G and this seems extreme. What should a average user be using in a month? ( ?MB)

2) The next issue blows my mind. Due to the fact that i used to have a SE p910i and it did connect with ease. The Experia seems unable to connect to the internet via the USB cable. It does connect to the PC to trf. files and music , photos etc , and it can use the internet via PC (connected to LAN) to do an update. Yet with my phone connected to PC i cannot simply use LAN through PC to browse on the phone. I know the phone is aimed at mobile connectivity via 2/3G and WiFi, i get that. But if my phone is connected to my PC most days when i am in the office ( it charges like this obviously) then why am i forced to use 3G or wifi, it seems odd that such an "amazing" phone in constrained like this. So if i want to browse the Android Market while connected to PC i am forced to use 3G or connect to a wifi network to do this , thus having to pay for data , that would otherwise be accessed if i could get access to the LAN.

Please can someone explain why an advanced handset, "smart" phone cant seem to do , what most handsets prior to these fancy touch screens could do. I mean i had a Samsung Omnia and decided to go back to SE, the Omnia could share its internet connection with my PC and it could also connect to the internet via the USB ( access LAN via PC)

SE dont you think it is embaressing that clients have to bring up issues like this. For all that android is , it seems more limiting in my experience so far , having used the X10 for 3 months.

SE please suprise me with some options or at least news of an update that can remedy what i would call an embarassing oversight. I think the Windows OS phones do this in their sleep.
