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.

How can I check got a successful Internet connect (Wifi/3G/whatever else) I already display an error to the user if they don't have Wifi connection but how can I make sure then that the user does got 3G connection if they wish to connect to use the application without the Wifi connection?
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()".............
View 5 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 wondering if would be possible to perform an action for each time the USB status of the device changes.
For example if the user plugs in the cable and it is in sync/charge mode it performs a certain action, if the user then changes the phone into USB Memory Card mode another action is performed and if the user then disconnects the cable then the another action is done.
I would like to know if it's possible check connectivity in android without having a Context, because the thread i have running in background doesn't know the context. if there's no way, is a best practice passing to the thread the context?

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.

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.

But it gives me network/ wifi connectivity if wifi is connected it gives me true and if internet is not connected then it also gives me true.
Iam connection to services trougth my app, I woul like to check if the connections gets broken, alert a message than.
Or is this taken carre of in android? If not, How should I take care of it? is there a timer?
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:.

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?

CODE:......................
I've already created a database for users using SQLite. The database name is Users and the table is called User. The records inside the table are Username, Password, LastName, FirstName. I've inserted one user's info into the database. The problem is I do not know whether my UserDB.java is correct.
And I've also created login.java. Hardcoded Login page:
CODE:........
So I want to know how I should apply the database connection on the login.java. Should I insert database connection something like db.Open();? I studied ASP.Net a few months back and I kind of forget most of what I've learnt.
So how should I open the database connection on login.java and how to check with database whether the user enters the right username and password?
Just incase you need my xml, here's the code:
CODE:......
I need to learn how to do it so that I can apply for other pages for example Register.java page.
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.

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?
View 6 Replies View RelatedI have work on Application That use Internet.
It contains XML parsing from url. than Showing Progress Dialog While parsing time. Stop dialog when parsing is done. set TEXT(Data) in ListView.
My issue is that, When device is connected to internet than my Apps works fine But when Device is not connected to internet "Progress dialog" is running for infinite time. I want to stop dialog if device is not connected to internet or wifi. how to do this? I have change my mind i want to check internet connection when i click on button. what i have tried so far is..
CODE:...................
But this is not working.if device is not connected to internet than i want to show AlertDialog. otherwise it will start Activity.
In my application I must use the internet connection ,so I check it first before I open an URL connection using this :-
public boolean IsConnectedToNetwork(ConnectivityManager conManager) { NetworkInfo allNetworkInfo = conManager.getActiveNetworkInfo(); NetworkInfo currNetworkInfo; boolean anythingConnected = false; for (int i = 0; i < allNetworkInfo.length; i++) { currNetworkInfo = allNetworkInfo[i];
if (currNetworkInfo.getState() == NetworkInfo.State.CONNECTED) { anythingConnected=true; }
}
return anythingConnected; }
However this code runs well when I connected to either the operator internet Or to a Wi-fi network. But when I'm connected to the operator but without credit and no internet the mobile also sees it as there's internet,or even connected to a Wi-fi network but without internet gateway it also sees as if it's connected to the internet.
when i plug my phone to htc sync, is there any setting that grant me Internet connection as well? phone data is switch off, wanna make use of the pc to access Internet. just like window mobile active-sync which allow device to connect to Internet via the PC connected via.
View 2 Replies View RelatedI am a newbie to Android so please excuse me if this is a silly question or one that has been answered many times before. When connecting to and using the Internet, I am trying to find out what determines the connection that the phone will use when more than one connection is available: Wifi, 3G etc. Is there a standard priority order for connection and use? can the user set the priority order? Usually I would expect the wifi connection to be preferred for reasons of speed and cost. I have looked at my phone user guide and the official Android user guide but cannot find any information about this.
View 4 Replies View RelatedI recently moved to an area that has limited internet choices which in turn makes for higher internet prices and longer contracts. A friend suggested a droid and tethering it using pdanet to my Mac. I use my internet primarily for browsing, sometimes I'd like to watch hulu or small pdf files through e-mail. Would this be a good option to consider or should I go with an internet connection? If I choose a droid, which one is the best one for tethering? I'm somewhat drawn to the ones with touch screens and no keyboards....but will listen to your reviews.
Supposedly verizon has a bandwidth limit of 5gb. Anyone know if that is monthly? How much is 5gb? Am I going to find myself a month out hating that I made the choice to rely on a droid for my primary internet source? Is there anything else I need to know about tethering a droid to my mac? Are there restrictions for OS X? Is there anything else I should know so I don't get the phone and hate myself later?
i have this android application that requires to load data from a remote server via the internet. this update-functionaliy obviously requires the device to not only be connected to some kind of network, but also to the internet.so: is want to schedule the update-service to some date and when it starts, it should determine whether it actually CAN reach the target server or not. therefore, a simple "is the device connected to wifi?" does not suffice, as the device may be connected to a wireless network that does not offer internet access. something like a PING is required.whats the easiest / best way to determine, if there is an internet connection is available i.e. server is reachable?
View 3 Replies View RelatedI 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.

I have the 3g connection on the magic and want to know if I can share it somehow to my laptop using a wireless network or the usb data cable. I would love to be able to surf the net on my laptop using the phone as the modem!

I have just got my Motorola Milestone ready and working. I have set up the Internet carrier APNs (HSDPA, EDGE, 3G etc) and I wonder if it is possible that Android asks me for confirmation when connecting to one? I don't like the idea of changing the APN name to cheat/workaround it (to make it impossible to connect by setting up non-existing APN), I like to see what connection possibilities are around me. When I'm at home I have a WiFi and also would like to be sure the whole transfer is being done by WiFi, not EDGE. With each connection request confirmation I'd be sure I have it under control.

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.
