Android :: No Data Connection While On Phone?
Dec 20, 2009
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 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??

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

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.

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.

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've got my Desire to allow background sync and auto sync etc, but I was wondering if there was an app that anyone knew of that would tell me which application has been using the data connection and for how long etc? A bit like the battery stats that says which application has been using the battery but for data connection if you see what I mean.
I've seen a few apps that seem to give an overall usage figure so you can track how much data you're downloading in a month but nothing per app.I originally posted this in the HTC Desire section but I think this section is more appropriate, not sure how to move a post so have done it again. Sorry if that's a problem.

Long time reader, first time poster here. How does one know if the Epic is using the wifi connection as opposed to using the 3G connection? When wifi is connected both that and the 3G connection shows at the top. So which one is in control per se? And how can it be verified?

T-Mobile myTouch 3G
Firmware version 1.6
Baseband Version 62.505.20.17H_2.22.19.261
Kernel Version 2.6.29.6-cm42

I have an unlimited data plan through T-Mobile. I am using my phone in the United States, West Coast. The issue I am having is when I am using the Tethering for root user and I receive or send a call, my connection seems to pause. This also causes web pages to not load and the 3G or E icon goes away from the Status bar at the top of the screen. Does anyone know of a way for me to have the data connection continue when a cell call comes in?

I have a scenario where I need to control how many retries are allowed per hour for data connection establishment in case of failure? How can this be achieved? There is something like nextReconnectDelay in GsmDataConnectionTracker.java, but can't figure out how to reconfigure this so as to reduce number of reconnection attempts? Also is there any settings so that after n retries of failed 3G data call, Android waits for x hours to initiate next connection.

HTC Sense has a widget to enable and disable your data connection. I don't want to use Sense though, and since disabling it, I don't have that button anymore. Anyone know of a widget I can use?

I've been trying to wrap my head around this and it's probably an obvious answer but why can't I dial out using my GV number unless I have a data connection active? Per Google and from what I can see, no VoIP is being used and it seems to me when I have a data connection and use GV to dial out it just dials a Google number first. I'd think the call would be made to GV, GV would patch the call through to the person being called and pass on the GV caller ID number. So why does the app need to have a data connection to work?

I have an app in which there are several requests to a server in internet (http), for example to retrieve images in threads outside the main UI process. The thing is that I have a Thread that manage the request with a while(!end) loop and in the end a Thread.sleep(500) that checks if there are new unhandled requests. As I read here [1] I know that this is not a good practice. And users have complain about ANR (app not responding) in several cases.
Knowing that obviously I want to refactor all the way my app manage the requests and I want to do that the best way. So, the question is; what is the best approach for doing this? A service? a broadcast receiver and send intents when I need a request to be handled?

I know that unfortunately detecting and changing programmatically data connection (GPRS/UMTS) on vanilla Android is not possible, and the common workaround is to edit APN settings. This is hardly a nice solution. However on my device (Xperia X10) I have an additional setting near "data roaming", that allows to enable or disable MMS and data. I suppose that this is a personalization made by Sony Ericsson, and maybe even other vendors have something like this. Is there a way to access this setting?

I use HTC Desire (updated to Froyo) and at home Google Maps Navigation works great and I never worry about the data connection because I have a large data allowance each month. But I'm now in Germany for a few days and I don't really want to pay roaming rates. So, I find that I can of course use the hotel wifi to plot the route.
This can work but most of the time it doesn't. The problem is that the route is not downloaded (at least not completely) until the phone has a GPS fix. Usually this happens after I'm out of range of the wifi signal and so I have no route to navigate. Is there a way of downloading the route without needing the satellite fix to validate it? This would make life so much simpler!

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.
