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 ?
You can use the 3G network for surfing the Internet and at the same time the wifi network to move files only?
View 9 Replies View RelatedI have a T-Mobile Galaxy Vibrant that was running Android 2.1. I rooted the phone (successfully), and installed Slim Bean 4.2.2 plus Google apps. 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.
My problem, I have a Samsung Infuse 4g with gingerbread which I installed through Odin with all the info I gathered reading post here. When the problem occurred of no network access, the phone had the stock froyo firmware and that had been working very well until now.
I cannot get data at all. I can get on wifi, send calls and text messages. I tried changing the mobile network access points and nothing. One thing that I did notice after reading all your post, was that my IMEI is a bunch of symbols, diamonds, question marks, etc.. but is not numbers like it should. The issue started with the stock firmware (froyo) and continues with GB. Another thing is that I have never backup the system at all, I currently cannot find an EFS folder, even after installing RootExplorer.
I dont put all kinds of fancy utilities on the phone, the only one there is Golf app. This just happened out of nowhere. The phone is not even a year old which I got from ATT. You can say, send back to ATT for warranty! I am a Soldier stationed in Germany, because my account with ATT is suspended until my return to the US, the warranty does not cover the phone. In the end I am screwed anyway since I changed the firmware to GB and it is rooted. My questions are;
1. Is it possible that I dont have an EFS folder?
2. The lack of EFS folder constitutes to an unreadable IMEI?
3. What can I do to fix it? Is there a dummy guide to fix this?
My friend was using my phone and he stopped some running services, since then my phone's wi-fi and GPRS not working, I have already tried restoring it to factory reset , but it doesn't work even after restoring phone to factory settings. Phone just keeps on searching wi fi network and in GPRS mode it shows network connection error.

View 2 Replies View RelatedI'm developing an App that sends keep-alive packets to its server to ensure the connection is still alive.
The server is java based and thus easily to run. I run the server on a virtual machine (Windows 7). After my App is connected and the first keep-alive packet is received (it displays a message in its console output) I disable the network interface in Windows. This step is very important because by disabling it, there is no way to send any packet back to the client informing it about network changes.
The clients are configured to send every 25 seconds a keep-alive packet, so you don't need to wait long.
When you use the sample JavaClient on Windows 7 it takes less than a minute after the keep-Alive packet and an exception is thrown which triggers reconnection (which currently can't occur). This is the expected behaviour.
When you use the sample Android App on an emulator (tested Android version 2 and 4) it is the same behaviour. So in less than a minute after the keep-alive packet it recognises that the connection is dead, throws an exception, this triggers reconnection.
Problem is now when this App runs on a real device (tested several, Xpearia Arc S, one Cyanogen Mod 4 on Galaxy S3 and my Galaxy S3). I've waited 5 minutes, but there was no exception. This behaviour is reproducable.
Since this is a sample App, it uses no wakelock or service, so to test it is important to have it in foreground all the time (don't switch to other Apps or homescreen) and increase your display timeout to a few minutes to ensure that it doesn't go off. Use Logcat-Output to get informed whats happening, because there is no output in the App itself.
Now Sample-Code is in the attachement. Something had gone wrong. The Code consists of 3 Eclipse projects which you can easily import.
I am having this error since last two weeks "Your SIM does not allow connection to this network." I have tried everything to the best of my knowledge:
- Reset Phone (Soft & Factory Settings both)
- Rooted Phone
- AnyCut application to reset Radio
- Updated radio to 63.18.55.06JU_6.35.09.26-signed
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.
Recently I've started facing a problem on my Desire. Sometimes it acts like the network is down, and the signal bar shows a cross. At that time when I tried another sim card, the network was working fine. Then after a while my phone starts showing network with the original sim. But it won't connect to the internet. It simply won't connect, although I am toggling the mobile data connection tick mark.
Right now the network has gone again, and I'm trying to get connected to it through either Automatic registration or manually selecting from the list of network providers. But I get the message "unable to connect to this network at this time"...
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?

Must say I'm loving android, for the sheer ability to customise it, altough not brave enough to root yet!
Installed folder organiser and launcher pro plus cos I want to change icons and names of folders etc.
My problem is when I switch from sense to laucher pro, i lose my data connection widget/ shortcut and cant get it back. On my sense screen I have the power control widget, which gives me the wifi connection toggle and also a mobile web toggle. I want a mobile web toggle that works with launcher pro.
Downloaded the widgets pack from curvefish, but the APN on/off does nothing at all.
Dinc will not obtain IP....I just updated to 2.2 and it worked fine .....then i made changes to my router......turned all the security OFF.....
Does the Dinc hold old info on a current connection? if so can i delete a connection and start fresh....more than just "forget"? Should I name my Routers SSID?
3G coverage where my office is located is really poor and the office doesn't have a wireless network (lol I know).
Is there any other way I can share my network connection from my laptop? I know I can use the 3G to my laptop but basically I want to reverse that.
Does anyone know if I activate the Wifi connection it trumps the carrier network connection? In other words, if the Wifi connection is active (assuming i have a signal) and my carrier signal is also active, and I want to stream some audio--which pipe does the phone use to bring in the audio?
View 11 Replies View RelatedAfter reading the forums and changing settings and doing a few battery cycles, I had been getting really good battery life of at least two days on medium usage and 3 days on light with my connection not having any real issues. Then, 2 days ago I installed weatherbug and beautiful widgets. While I enjoy both, it seems like my network connection goes down fairly often now and I need to turn on wifi to check email or do anything else web related. Has anyone else lost their network connection and been able to narrow down the cause? I'm hoping it's not one of these two, but I can't imagine what else it would be.
View 5 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!

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 have been a very happy HTC Magic user for exactly 6 months now but then a strange thing happened; I work up new year's day and I could no longer connect to internet or use my apps (and the 'G' network symbol has disappeared from my system tray). I thought the network (SFR in France) may have had a hangover from the night before but no, the problem persisted into day 2. I went into the SFR retail shop on 2 January and the assistant played with every option of my handset's menu for 20 minutes before declaring "I suggest you go home and reinstall the OS from the CD that would have come with the phone".. or at least that's what I think he said as my grasp of French is not absolute. He also offered to send the phone away to reset it or something.
I am convinced, though, I didn't get a CD with the HTC because the box is only half the width of a CD! I recall a USB type cable in the box though. So I turned to these forums and tried the advice given previously by Carl C but that didn't help. I've tried every logical option in the phone's settings (and the 'G' icon does appear for half a second in the system tray after I change/save a setting, before disappearing again) so I'm convinced the problem does not lie there. I am even considering uninstalling some of my recent apps in case they may have inadvertantly caused this problem............

Im 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.

I did a search and couldn't really find any threads with people having similar issues. I saw that people were having trouble keeping their X connected to a network, but that's not my issue.
I have a Droid Incredible and added a line to get the X figuring I'd just sell off the Inc when my X arrived. Since I got my X, I've noticed that when I am connected to a wifi network, it almost seems to crawl when I hop around from page to page.
I ran some speed tests on my internet connection, it seemed that it was my phone. So then I ran speed tests with the app in the marketplace, first on the DInc and then on X. The upload speeds were pretty close to identical, but the download speeds were consistently 300 kbps higher on the Droid Incredible.
So after running those tests, I decided to just do some side by side browsing on the X and Inc to see how big the difference was between the two. I opened up a few pages that I don't ever really visit so they weren't in my browsing history and the Incredible would again open pages 10-15 seconds quicker.
Has anyone else had these same issues? I know their was a software release shortly after the initial launch, is their another one in the pipeline?
I love the phone, it's a multimedia beast. But I don't think I want to keep one that has a busted wifi connection.
