Android :: Sending Data To Dev Phone Using 3G Connection
Aug 3, 2009
I have a server application listening on port 5001 on an anroid dev phone. The client application running on my laptop tries to send data to the server application.
The client can successfully connect and send data to the server machine when the phone has wifi enabled. The command to do this is - iperf -c <ip address of wifi interface>
But when I enable the 3G connection and try to send data then it fails. iperf -c <ip address of the 3G interface>
I cannot even ping the <ip address of the 3G interface>. Is there any port blocking enforced in case of external 3G network connection. Can anyone please tell me how can I send data to the server application on 3G network. Is there any specific port on which the server application should be listening??

Dear I have an app developed and deployed on my HTC mobile phone. I am able to debug this in eclipse with the USB driver SDK. The mobile phone appears now in the hardware manager ADB interface. I would now be able to send data through this USB connection to the mobilephone which my app is able to handle. I know some tethering software which does this, therefore there must be a way to communicate with user data and with my app.

I saw this commercial the other day for the iPhone where they were saying how the iPhone can look up stuff on a map and lookup restuarant info on the web all while on a phone call. I thought, that's silly, can't every smart phone do that? I had never tried it before on my Hero, so tonight I just did a simple test, where I was on the phone and tried to look up some info on the web. No go. There was no data connection. Boy was I not happy about that. Is that a function of the OS (v1.5), or the network I'm on (Sprint)? It seems like its pretty basic that I should be able to be on a phone call AND look something up at the same time, just like the iPhone commercial. Or am I doing something wrong? Is there a setting somewhere?

I tried getting my new HTC Magic to work with my Tom Tom Sat Nav, the basics worked fine but then I got this message. Your phone needs to support Wireless Data Connection (Dun) Capabilities to use TomTom Plus Services. Can this be done soon? I need to use those services, would it be an update type download or a separate download? or if there is already a setting please let me know asap

Does anyone know if the VZW Backup application can send contacts to the Droid? I'm currently using a non smartphone that uses VZW Backup to back up my contacts on the phone online somewhere. I don't know if the Droid is compatible with the VZW Backup app tho.

I got the phone last week and very disappointed with low sound volume but seems I am not alone....anyway that's not my question.I am interested in how much my 3G connection is active and how much data my phone is receiving/sending. I installed the 3G Watchdog app and for example this morning with browsing BBC website with NO downloads etc it is showing 4.76MB data alone (3.96MB received and 838KB transmitted). My 3G connection is almost always flashing with the arrows showing data transfer but what is it?!
Facebook has all updates off
Email is synced hourly
Moxier calendar daily
I seem to have a "background" data transfer of 3MB/day and this is without any browsing etc...what is going on?!

What's the technical term for being able to have voice connection and data connection simultaneously? Like AT&T was promoting heavily for a while.Apparently, the new T-Mobile Vibrant has this capability. A friend got one and was accessing the web while talking to me, double jealous now.I have benn lusting after the Verizon version, Fascinate, and wondering if there is any chance it will as well.

Okay so my phone keeps dropping 3G and it wont be able to find it for hours but then it will find it then lose it again. I tried restarting the phone and it still is doing it. I also looked on my brother's Evo and his has connection when mine does not so I know it is not a problem with our tower, any suggestions on what to do.

some apps sending GPS and phone# data surreptitiously to advertising servers
Some Apps caught sending private data to advertising servers
you may want to check if your apps are on the list & decide if you're OK with keeping them.
I believe I have the BBC app installed.
I just checked but my BBC app looks like it is the official one

Is anyone else not getting a mobile internet connection right now? This has happened before on Orange but it's different this time because my phone doesn't seem to be searching for a network to join (before in the settings it would say "searching" or something and be greyed out but not this time)
Hopefully it's just a network problem, rather than my phone
I've managed to fix it i think. It would seem something I installed (im thinking SwitchPro Widget) changed the APN name in the settings to orangeinternet_off.

Principally to save battery charge, i need to find an application or a method that automatically shut down data connection when i lock the screen and resume it when i unlock the screen.
I've tried many of the most popular software that do this, but, with dual sim phone, they are able to shut down data connection but not to startup.

My main phone is my new HTC Sensation, and I have all my regular apps installed on there (via the Android market, using my Google account).
My old phone - Rooted HTC Hero - I keep as a spare, and use only when I am travelling overseas, to put a local SIM Card into.
My question is, can I install apps on the spare phone on an ad-hoc basis, without using my regular Google account?
Ideally, downloading .apk files for Android market apps?
As it's only a spare, and mainly used for voice not data, i don't really want all the same apps as on my main phone, just some of them -things like Go SMS, JuiceDefender, etc
Also currently, the plan I have with the local SIM card I'm currently using has no data - only voice. So apart from connecting it via my laptop, I could only install apps using free wifi.

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

So, first, here's what happened. Did a factory reset of my phone. When it came back up and I went to activate it, no data connection, unable to make phone calls. After 2 hours on the phone with VZW tech support, I can make calls, but have no data connection. They are sending me a "new" one. The concensus of the VZW tech and myself, problem with my phone. 2 days later, my wife resets her phone because of memory usage issues (she had to much on it). Same exact thing happened to her. Being the fiesty woman that she is she is going to a VZW store today to raise holy hell and throughorly degrade the poor rep that she is going to talk to, to get some answers. My question to all my fine fellow Eris users, have you seen this before? If in our position, do we deserve a new phone, and not an eris? Will this happen with a replacement eris due to a fault in the 2.1 update?

I'm trying to get ksoap2 working on android. I have spent at least 10 hours now reading forum posts, and documentations. Just querying some methods like getServerTime where I don't have to send any values, works. My goal is to send data, and receive a response. For example: send city name, get city time.
I'm practicing on this site: http://www.nanonull.com/TimeService/TimeService.asmx
This is my code:

Ok, I have 2 Activities I want to send data between activity A and B.My problem is that some random code of mine seems to be called between startActivityForResult() and onActivityResult()in Activity A.This doesn't make any sense because there is no code after startActivityForResult() is called.Shouldn't onActivityResult() be the first thing A does after B finishes?

I have a broadcast receiver the looks at SMS, when it receives an SMS that is destined for my application it needs to send some data to an activity or start the activity if it is not running. How do I find out if the activity is running and send data to it if it is? I know I can use StartActivity and stuff the intent with the data I want to send to it but if I start the activity that is already running, another instance of it will be created (wont it?).

I'm writing a Android gps application using locationmanager with locationlistener and I'm only testing with the emulator. This is my problem. - When sending only $GPGGA nmea sentences to emulator by telnet, everything works fine. - When sending only $GPRMC nmea sentences to emulator by telnet, the first location is recognized by locationmanager, the gps provider goes into status 2, next $GPRMC sentence is not recognized.
This happens not only with my application, the Google Maps application and also others show the same behavior: they get only the first $GPRMC location. When sending a $GPGGA sentence after the $GPRMC, the locationlistener gets control and location is shown.

Is there already functionality similar to the push registry or wireless messaging API in J2ME implemented in Android? Or at least plans to do so?I have been looking at this issue for a while, because in a corporate environment it is essential to be able to push information out, or trigger actions via SMS or other connections.I have successfully sent an SMS between emulator instances, and successfully received an SMS by using a BroadcastReceiver on another emulator instance. I have also been able to use SmsManager. sendDataMessage to send a data message to a port on another emulator instance, but in this case the BroadcastReceiver is never triggered. This seems to be the closest the API's get to what I'm looking for.

I am little confused with the use of intents used for sending data to activity from service. In my application I have to have startactivity from the service and have to pass data ,so that activity can utilize the data while launching.For this i have written the following code Intent intent = new Intent(Service.this,Activity.class); intent.putExtra("data", data); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.start Activity(); I assume that the data is passed to the activity and can be parsed on the oncreate function of the activity.Now the service running in the background has to pass data to the activity continously for UI updates.For this I have written the following codeIntent intent = new Intent(Service.this, Activity.class); intent.putExtra("Data", data); intent.setAction(Intent.ACTION_ATTACH_DATA); sendBroadcast(intent,null); (Do I need to broadcast the intent???) In activity I have done following things:- Implemented broadcast reciever:private BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { if (Intent.ACTION_ATTACH_DATA.equals(intent.getAction())) { Bundle extra = intent.getExtras(); float Data[] = extra.getFloatArray("Data"); update(Data);

I have a main class activity that does the task of sending control to other activities on click of a button. I am also starting a thread in the main class. This thread basically sets up a connection with the server and is active throughout the lifetime of the application.I have two functions in the thread class, send and receive data from server.Therefore, when the other activities need to send/receive data from server, they use those particular functions.First of all please let me know if what I am trying to do is fine as per the architecture of the operating system. If its fine, when I try to run the code, the app crashes and i see a NullPointerException and a RuntimeException in the DDMS log.Could some one please help me out in this or suggest a better way to implement the concept.Also, please be assured that, the other functionality of the code works perfectly fine.

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?
