I'm building an application for my own use, and I like to get connection via mobile network but I don't know how to do that. What I want is the same behaviour that offers severals existent widgets to turn on/off the data connection.

I am developing an Android application and I would like to setup a tcp/ip type of connection between two Android phones using the 3G/Edge network. My test version will establish a connection if I have both phones on a lan using wifi but when I use T-Mobile's network a connection is not established. Could this issue be a port or ip address?

View 6 Replies View RelatedI got my HTC Hero the other day and am very very happy with it. The only problem is that I cannot connect to the internet through "Mobile Network". I am on a "3" contract and I am able to access "my 3" which is where I can look at my account, look at my last bill, check my usage, etc. I can also connect to 3 - Home - that loads fine. But any other website (google, bbc, facebook, etc.) will not load - it just times out after a while.
It seams obvious to me that this is an issue with my account on 3. I don't know how many hours I've been on the phone to these guys. I have gone through all the settings with them, more than twice - replaced my SIM card and tried my SIM in another phone. So Three are now looking into it and have passed my issue onto the network's team, now they said that it may take up to 21 days for someone to get back to me!
Does anyone know why in wireless & network settings it says connection failed under mobile networks?It'l connect to 3g for a bit but then come up with connection failed?
View 1 Replies View RelatedIm wondering if this is an issue with my phone or an issue with the network in my area. Basically, i try to turn on my mobile network and it freezes at "turning on" i hit the back arrow, head back in and it says that the connection failed or "standby for connecting to the mobile network.The only thing different i have done today is install spare parts, and read a few issues people had with sense turning off, and wondered if maybe something within it is bugging my phone, just a thought though.

Everything was going smoothly and I was reinstalling apps and data when I noticed that I had no network phone connection. Slim Beam did not seem to recognize the sim, and I came up empty searching for networks. I removed the sim and put it in another phone, and everything was fine.
I decided to restore the previous android 2.1 (which I had backed up) using ClockWorkMod Recovery. I did restore, then reboot. Now the only thing I get is the initial screen ... Vibrant and Samsung in bold white letters. I have tried repeatedly to launch CWM Recovery, without success.
I using the Cyanogenmod 10 with JB . I got a big problem cause every time i turn my phone into standby i loss my connection to internet and also i loss my mobile signal. after unlock my screen i have 2 enter my pin , i can only phone emergency. when i enter my pin, the phone reconnect and i got signal. i tried nearly every update, i flashed stock ROM and re-flashed cm10, nothing better.
View 2 Replies View RelatedI have been trying to find a way of quickly switching off/on the Mobile Network setting from the home screen. When searching Google there's loads of pages stating that it is an HTC Widget that can be added. I have checked all the widgets on the Desire HD and cannot seem to find it anywhere. I am using an unbranded handset.
The Desire HD manual even states "You can also add widgets that allow you to quickly switch on or off certain settings of your phone, such as Wi-Fi, Mobile Network...".
Does anyone else with an HD handset have this widget ?
I have been looking at the ConnectivityManager class documented at http://developer.android.com/reference/android/net/ConnectivityManage... .
I would like to know if an Android application can open a network connection (socket) on a specified network interface [on a device supporting multiple network interface types WiFi, Cellular, WiMax etc] ? I am looking for the capability for an application to open a socket on a given type of network for example over WiFi network or over 3G Cellular Data network.
If this is possible in Android, how would I code this requirement within the API Framework ? The ConnectivityManager enables an application to learn about available network connections and currently categorises them as either TYPE_WIFI or TYPE_MOBILE.
There is a member function in the ConnectivityManager class called requestRouteToHost(int,int) [url] which "Ensure that a network route exists to deliver traffic to the specified host via the specified network interface. An attempt to add a route that already exists is ignored, but treated as successful." Sounds like this would install an IP routing table entry to reach a given host via a specified network interface type (WiFi or Mobile). After calling this would it be sufficient for an application to open a socket and connect to the desired destination address ?
Or perhaps the application needs to bind() a socket to a local address of a network interface of the desired type (WiFi or Mobile) Or by setting a socket-level socket option of SO_DONTROUTE ?
I seem to be seeing an issue with the data network access on the EVO. When it happens none of my applications get internet aceess and my mobile network status says "turning on". The only way I've found to fix it is to pull the battery. Any one else seeing this? If so is there a better fix than pulling the battery?
View 5 Replies View RelatedMy eris has always has pretty alright battery life, what I would expect out of a smartphone, if unplugged at 9AM it usually was running on its last leg around midnight. I've had it for over 5 months now, I've always had it activated on alltel, I installed the 2.1v3 leak before the official OTA was out and just lately it seems like there something very wrong with my battery life...
If I unplug my phone at 9AM within the past week and occasionaly check and respond to a text message, my battery had been down to almost 30% by NOON... what?..
I have noticed that if I disable Mobile Network (3g/1x data), the thing lasts all day and some... If I turn mobile network ON, I can't see that I have any network traffic or any apps running in the background that are syncing data at all... I've had google account sync mess up on me before and have to reset my google account because it gets stuck in a syncing loop, but its not doing that, already checked. Very weird.
Anyone thing it could be something wrong in my ##PROGRAM#/##778# provisioning menu, maybe something got changed?.. Maybe it could be do to Alltel's AT&T merger that's happening right now, maybe some 3G tower's radios are turned off or something...
I love my aria, i got it 9/29/10, for free from best buy because my contract expired... but ive already used 20MB and i only bought a 200MB plan... i might go to 2 gigs, but for an alternate, since my billing cycle ends the 28th of every month... if i disable application syncing, and mobile network from the hold menu... can i connect to my home wifi network, and go on the internet from there without that using any of my data plan?

Network: Base - a brand of e-plus, Germany
Taskiller Used: None
Issue: Switch on tethering OR mobile hotspot ->mobile network dies
I've installed Froyo on a T-Mobile branded Desire. After the update, turning on USB tethering leads to immediate loss of mobile network - it just turns itself off. Same goes for the mobile Wifi hotspot: turn on -> for 2 seconds, it's working -> mobile network drops off. Moving into airplane mode and back brings back the network, but tethering is a goner. With 2.1, USB tethering had worked. I'm on Base, a brand of e-plus. I've talked to their customer services, they say Base absolutely supports tethering.
I need to make HTTP request on Android using GSM connection, not Wifi. My current solution is to disconnect from all wi-fi connections and perform a request. Is there any better solution? I could not find any relevant methods in the API (I looked in package org.apache.http, but it seems it is completely unaware of what type of connection should be used).
View 1 Replies View RelatedI'm working on some data transmission program and current it works alright on WIFI connection.
However, I understand that if I am in an environment where there are both 3G and WIFI coverage... the phone will (by default) be turned onto the WIFI network connection.
However, if for some reasons, I wish to be connected directly to 3G (e.g. 3G is more stable in public WIFI area).... is it possible to do so programatically on the Android phone? If i'm not wrong, it's possible using the ConnectionManager API, am I right?
May i ask if anyone has done something like that and don't mind sharing the code snippets to do so , or point me to the right direction for this?
I wonder if anybody has ran into the issue where a running emulator would lose network connection all at a sudden for no obvious reason. And I am sure the computer running the JVM is still online.Restarting the emulator seems to fix the issue but it's been a major PITA for me as it interrupts the work flow.I am using 2.1 SDK 7.

How do you detect the network connection type on Android?
Is it through ConnectivityManager.getActiveNetworkInfo().getType(), and the answer is limited to Wifi and mobile?

View 3 Replies View RelatedI am writing a UDP client/server application. The android phone (client) can send and receive UDP packets if connected to wi-fi. When using mobile network (2G), however, it can send packets to the server, but cannot receive packets. The server does receive and send back packets in all cases. The client side code is as follows: byte[] buf = new byte[4096];DatagramPacket packet = new DatagramPacket(buf, buf.length);while (true) {packet.setData(buf); socket.receive(packet);
View 2 Replies View RelatedIn my application it is necessary to have internet connection. Therefore i check while starting if a Internet connection is available. If not I ask the user if he would establish an Internet Connection, and what type (wifi oder mobile). The wifi connection i can establish with the following code WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
wifiManager.setWifiEnabled(true); But how do i establish a mobile connection? Couldn't find a single code snippet at Google.
Trying out a vibrant. The T-Mo rep told me it used the hspa plus network. Now i read the the first hspa plus phone for T-Mo will the HTC vision/vibrant. Was i lied to? It is a bit of a moot point, if the vision/vanguard has a bigger screen and real keyboard i will be re boxing the vibrant and limping the G1 into September.

- Reset Phone (Soft & Factory Settings both)
- Rooted Phone

I want to check that the network connection is alive on the phone from program but when i try to run this code
Code:
private boolean isOnline() {
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo netInfo = cm.getActiveNetworkInfo();
if (netInfo != null && netInfo.isConnectedOrConnecting()) {
return true;
}
return false;
}
I get the message "Sorry 'Appname' is stopped unexpectedly. Try again".I might have to search the solution elsewhere, i added permissions for network, run the application and got the same error but when i tried to start it from the menu it said application not installed.
This was working until today on wife's phone.Now it just says mobile data state disconnected. All shes done is installed a load of new apps.Is it possible that a bad app can screw the mobile data connection?Or could it be faulty phone?Tried the sim in another phone and data works fine so its not the network or sim.
