I'm new to Android development and working on an Android application that requires the phone to be connected to the internet, through either Wifi, EDGE or 3G.
This is the code that I'm using to check whether an internet connection is available
CODE:................
I've also set these permissions in the manifest file.
CODE:.................
This works fine in the emulator running version 1.5 of Android when 3G is enabled, but it crashes when I disable the 3G connection. My application throws a null pointer exception when I call isConnectedOrConnecting(). The same thing also happens on my HTC Desire running Android 2.1.
I want to create an Android service, which notifies the main activity whenever disconnects and when internet reconnects again. I have following function for checking internet connectivity:.
CODE:...........
But I want to know, how to use it in a service.
I am working to send request to internet and get data, my emulator show the 3G sign on it, i have also sent the permission to internet connectivity in my app. But when i click on button to send request it return null. I have checked the request link in chrom it send data successfully.

View 3 Replies View RelatedI am looking at which HTC phone to buy. I need WiFi to connect to the Internet at home. I also want PUSH email, my understand of PUSH email is that every half n hour or something I can get the software to go out and search for new emails whilst not having to go into the app and click refresh to see new emails, something which I have to do on my N95. I also need a decent SatNAV, now I know that google navigation is out. I don't know how good it is due to the lack of information out on the Internet. Do all HTC phones drain the battery with GPS? Okay so I need SatNAV, then I also need a phone with decent car cradles, I need something that enables me to rotation it portrait and landscape easily.
Do HTC phones come with a car charger in the box? I also use Gmail a lot, now is there any advantages that I will get from getting a HTC phone and utilizing my Gmail account, as well as calendar. Is there a simple way of getting the phone to sync with outlook such as the tasks and notes you make? Are most applications on Android free? Do the phones last a long time? I like the idea of the kickstand in the Droid incredible I think, that phone is very appealing for me. I am just thinking of getting the phone not for phone and text use but for just Internet and applications.
So I dropped AT&T for the Incredible and my number successfully ported over, but I cannot connect to the Internet.I can make/receive calls and SMS, but no Internet besides wifi.I've been on with vzw support and went through reactivating the phone (*228) and a couple hard reset to no avail.They said it could have something to do with porting from AT&T, but I'm not understanding that connection.I don't have too much faith in support figuring out so I'm trying this forum. Does anyone have a clue how to resolve this or is it a defect with the phone.Some details: there is no 3G symbol near the signal status bars.Settings/Wireless & networks: shows "Mobile Network" with a green check, buts its grayed out so no action can be taken on it.Directly underneath "Mobile Network" it says "Turning on..." and it seems to flash that status every once in a while.
View 5 Replies View Relatedmy WiFi on my Evo has been acting up, so I went and restarted modem and router, turned off WiFi on Evo, battery pull Evo, then as a last resort, I updated my router's firmware (since its been over a year since update =/) so I figured maybe that would solve something. Nope, can't even update Twitter, Facebook, get on internet. I did update on 6/28 and everything went smooth and my WiFi was working then. I have done nothing since and then all of a sudden, last night and today WiFi wont work.
I guess to explain this better, I can connect to my router, Evo shows that I'm connected with Good/Excellent connection and 55 mbps, but its like no internet connectivity, Facebook, Twitter, Internet, nothing. Like I've said up until last night everything was working until now. Did the update on 6/28 just slowly kill my WiFi?
Anybody notice they are losing their Internet connectivity while tethering with 2.2 Roms. I have run BB, Kangerade, and CM6 rc1&2 with them all losing Internet connectivity completely. I have tried different kernels and different baseband all resulting in the connectivity loss. Is this a hardware problem with the phone or is it software based. This is a somewhat new phone and I honestly can't remember my previous one giving me this many problems while running 2.2 roms when they first came out.
View 10 Replies View RelatedMy Epic 4G just lost all connection to the internet about an hour ago. Out of the blue, so to speak. I was browsing, set it down, then when I used it again it wouldn't connect. My browser, facebook, and any other connection required apps throw error messages saying - "connection error", "no connection". I've reset the phone several times, and as far as for the network settings, everything looks set the way it always is. I have done nothing to the network settings/options to have accidentally messed it up myself. I am connected via 3G, and this network problem is new to me. This phone has been nothing but constant problems and this is the newest one in a long list.
View 2 Replies View RelatedThe H symbol is displayed at the top of the screen and the arrows occasionally flash. The 'up arrow' flashes more often than the 'down arrow'. I have at least 2-4 bars reception.
However when I try to browse there is a 'data connectivity problem' and websites will not load. None of my apps, gmail, facebook etc will sync.
I am on t-mobile.
Fixes I have tried:
- turn on/off
- APN settings check
- Airplane mode
Have spent hours looking at other 3g threads, but have not found an identical problem. My phone says im connected to 3g ('H'), but will not update email or let me access websites on the browser.
What is the simplest way to check whether my app can access the internet? I am using some APIs that use the internet, but they crash if there is no connectivity. So I just want to check if there is internet access by any means.

View 1 Replies View RelatedI'm basically trying to check that the device is connected to the internet to that I can access and parse an RSS feed. This is also the 1st android app I have written so I'm still finding my way around so any help/advice would be appreciated. I'm sure the variables should be assigned to something but I don't know what. The classes don't appear to have public constructors so I can't do "WifiInfo info = new WifiInfo()".............

It will be perfect if our app can access internet without asking for the permission INTERNET. I found it is OK to open browser with a URL without that permission but the user will notice that. Is there a way to access Internet without the INTERNET permission and hide from user?
View 3 Replies View RelatedI was trying to make an anonymous class to upload a file to a server.
I wanted to make that easily reusable much like some kind of component.
Everything works fine but as a final touch i wanted to add a function to check if internet connection is available.
Problem is, the call to the connectivity manager needs the Context :
ConnectivityManager connec = (ConnectivityManager) getSystemService (Context.CONNECTIVITY_SERVICE);
Since i'm in an anonymous class and I've read that it's not a good idea to pass the whole context to classes, I wondered about two things :
1 - Is there another way to check internet connection without the Context ? 2 - Why in Android internals make it necessary to have the context just to check if the device is connected to internet ?
I was just wondering how, if possible, to check Internet usage? I'm with Orange on a monthly contract, think my allowance is 500GB a month? Is there a way to check usage as going along, don't fancy getting a bill at the end of the month which is huge! Say I use the Internet (Google, Facebook etc etc) one hour a day, is that a reasonable amount to be within the 500GB limit? I don't want to get a huge surprise when the monthly bill comes through.
View 5 Replies View RelatedSo I was very happy to show off my Hero to my friend who just got his pre. Anyway he was on this website to check his internet speed on his pre and so I wanted to check mine. I was averaging ~500kbps and I hit 1000kbps once. But my friend, he was averaging 8.5MBps, yes MBps. Obviously same network, at the same time. What up wit dat?
We also tried to go to websites we had never been to at the same time and he was beating me pretty handly. Anyway, I wanted to see what you guys were getting? Site is mobilespeedtest.com, then it run test and post results! Whoa, just did it right now and I got 1311kbps.
Does the Epic have a spell checker that works w/ email, text, & Internet browser?

It states that enabling this will "require more battery plus view of sky"
When checked, it states "deselect to conserve battery"
So, the question is, should this be enabled?
I imagine for some applications, knowing your precise location should be useful, especially if the turn-by-turn maps are installed and used.
I'm thinking to deselect this, and selecting it at times when I need it.
So, to check or not to check?
My application has some code which detects if the Android device is connected to a Wi-Fi or Mobile network.
The code appeared to be working fine for Andoid 1.5, but does not seem to work correctly for Andorid 1.6.
Here is the code I am using:
CODE:..........................
Under Android 1.5 this code would correctly detect if the current connectivity was Wi-Fi or Mobile. However under Android 1.6 the call to getActiveNetworkInfo seems to always return a networkInfo instance with the type set to TYPE_MOBILE. This is happening even though the icons in the bar at the top of the android screen show the Wi-Fi connected icon with the full signal strength bars showing.
I don't know if this means that under Android 1.6 it is actually using the phone data network for connectivity instead of the Wi-Fi connectivity when both networks are available, or if the getActiveNetworkInfo call is just returning the wrong information for Android 1.6.
Has anyone else seen this issue with Andoid 1.6? It would be too bad if 1.6 is really using the bandwidth on the phone data network instead of the Wi-Fi network when both networks are present. Does anyone know if there is a different way to correctly detect if the Android device has Wi-Fi connectivity?
I am with first Droid phone. I have had an HTC Desire for approximately 1 week and absolutely love it. When I first got the phone, the connectivity was always H in the status bar, with very good I-net speed. For some reason, unbeknown to me, it is now a G, sometimes a 3G. The speed is still quite good though. This 'change' would appear to have been since I received a text from T-Mobile (I'm aware of the 'G' issues on their forums) alongwith the lines. They hoped I liked their new webpage. Now they have reverted to the original webpage I may have to re-load my favorites. I have not had to do this, thankfully. Under Wireless & Networks, WiFi is off, as I am on an 'unlimited' 3GB plan, and I am using GSM/WCDMA auto under Preferred network mode.
Questions: -
1. What is the difference between the three, namely H, 3G and G?
2. Which is quicker?
2. Can I change it back to H, if I wanted, as I believe it was quicker?
4. Sometimes, although not very often, the G, 3G and H disappear altogether and I am left with no connectivity at all. However, if I try to access the I-net, I can, and either the G, 3G or H appear again miraculously. Is there a particular reason for this?
Hope to hear from you experts soon and apologies for such basic questions, as I'm still getting used to using a droid. My last phone was a Nokia N95 2GB. Huge difference!
We are developing an Android application that uses bluetooth to connect to a board that we developed. If we try to connect to the board after the system has been off for a while, the system connects correctly and begins to stream data. The data stream will freeze momentarily, then start, then freeze, then shut off after about 6 - 8 seconds. If we try again it will repeat this process. It is almost like the Android is checking to see if it is an ok device to connect with, and decides no for some reason.
The only way we have been able to then connect again is to un-pair and then re-pair the tablet to the board. After we unpair and re-pair, the connection works well and will continue to work well until we turn the tablet off.

I am currently in China and therefor run a VPN on my PC to connect to the outside world, I would also like to run the same VPN (PPTP) on my android. I can connect via VPN if I am using WiFi but when I try to connect over GPRS/Edge I can't get any connectivity. All web pages load with the standard "web page not available" and apps, eg. the market place, won't connect either. I would have thought that if it was a carrier issue (CMCC) I wouldn't be able to connect to the VPN in the first place. So is this a Android issue, a setup issue or a carrier issue? And can you actuality run a VPN over GPRS om Android?
