3g

问题 Currently, I need to perform some network communication with a mobile gateway. The mobile gateway is expecting 3G network traffic of selected telco operator. I was wondering, is there any I can mimic such traffic from my laptop? Or, from my 3G smartphone which is not subscribed to selected telco operator? The reason I ask so is selected telco is a foreign telco. Hence, it is not possible to use its sim card locally. Is there any way, or any services, for me to mimic 3G network traffic from

问题 I have made an App that can connect to a program that I am running on a server, but it only seems to work with WiFi. When I try to use 3G it doesn't make the connection. Is there something special that I have to turn on or set in order to use 3G? 回答1: At the application level you (normally) don't have to worry about what data connection is available to the phone. Have you looked into problems such as when you use WiFi you web server is accessible since you are hitting it from within your

问题 I am running into a annoying problem with HTC Legend (Android 2.2). Not seeing this issue on Xperia, Galaxy, Nexus, etc. When I launch my app on a 3G connection, fetch some data, then go into phone Settings and enable WIFI, the phone automatically obtains a WIFI connection which is favoured over 3G. The trouble is, once i switch back to the app, it appears to have lost all network connectivty and unable to connect to anything. However, other apps, like Web Browser for example, have no problem

I want to read file from one device to another device and write the same using wifi of both devices same as the way we can do using Bluetooth . Is it

问题 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! 回答1: 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
