3g

I have an app I'm writing that crashes when I call addSubview on a UIScrollView with "EXC_BAD_ACCESS". It only does this on iPhone 3G in release mode and only on the device. I works fine in all these other configurations: iPhone 3G - Debug mode iPhone 3GS - Debug AND Release Mode iPhone 4 - Debug AND Release Mode Simulator - all. Furthermore, there is no rational reason why this should be happening. My object is not released by any of my code. I had the exact same problem recently, however I am not entirely sure the cause is the same. What I can tell you though is what resolved the issue for

I am just wondering how to enable/disable 3G/2G using the Android SDK and not just intenting to the 3G settings page. Thanks. Also is there a way to do the same thing, but with GPS. Thanks! There is no exported to the SDK functionality to switch between 2G and 3G. For a given device you could probably figure out the private functionality, but it wouldn't work unless the app was signed with the system key. You can disable the radios though, by turning on airplane mode. And you might be able to make a shortcut to open the appropriate settings activity directly, instead of going through a few

Right now, I am having application which works with WiFi, but while I am going to mobile providers network my application does not working. I have maintained one background service which checks for network, but im not getting how to handle network switch WiFi to Mobile and Mobile to WiFi? I am not getting how to handle WiFi to mobile network switch because already WiFi is enabled and I am not in WiFi coverage area; in this situation I want to get switched to mobile network automatically and vice-versa. My approach is as follows which is not working: String networkStatus = "disconnected"; int

Is there any way to use UPnP for NAT traversal on Android with a 3G/4G connection, and if so, is it carrier dependent? No, for the time being thee is no way to do that, for the simple reason that the mobile carriers don't use residential-class NATs - what they have is "Carrier-Grade NATs" CGN, see here http://en.wikipedia.org/wiki/Carrier-grade_NAT , and these devices have very different port allocation and management mechanisms from the residential gateways. See the Carrier-Grade NAT (CGN) related documents in this collection: http://www.scribd.com/collections/3292450/P2P PS there currently

Some Huawei 3g modems like mine (E1752) has ability to make and receive calls. I believe onboard there is PCM channel that can be used while making or receiving the calls but I do not have any more information on that. I am using their app called the Mobile Partner which is a fairly complete app which supports making and receiving calls. But I want to build my own app which will run on Mac OS X. But I am not able to locate any documents detailing the Voice API and the onboard PCM channel. If anybody is aware of this please let me know. Thanks Harryd Sai Chaitanya Voice is implemented as

For statistic network traffic per APP, what I'm using now is Android TrafficStats That I can get result like following : Youtube 50.30 MBytes Facebook 21.39 MBytes Google Play 103.38 MBytes (and more...) As I know, the "Android Trafficstats" just a native pointer to a c file. (maybe an .so ?) But it mixed Wifi & 3g traffic, is there any way to only get non-WiFi traffic statistic ? RRTW Evening all, I got some way to do that... First I have to create a class which extends BroadcasrReceiver, like this: Manifest definition: <receiver android:name=".core.CoreReceiver" android:enabled="true"

I am working on an iOS app, and want to determine which type of cellular connection the device has. I'm most interested in the kind of cellular network my device is using: 2G or 3G, or other. However, the Reachability.h only provides checking for wifi or 3G. How can I check for 2G, 3G, etc? 2G / 3G cannot be distinguished via Reachability.h or any other third party libraries, as iPhone only provides network type information ( WWAN , WiFi , no Network ) to API. However, if you are able to know the IP range of 2G or 3G network, you can determine which network speed / frequency the iPhone is
