my android device supports both wifi and 3g. At particular time which network is available on this device. Because my requirement is when 3g is available I have to upload small amount of data. when wifi is available entire data have to upload. So, I have to check connection is wifi or 3g.

How to check any kind of network status in android...
View 1 Replies View RelatedWe have a very patchy wi-fi network here. The wi-fi router's pretty old and I tend to need to switch it off and on every couple of days. Is there an app I can use that will - perhaps in conjunction with Locale so it only runs when I'm in the office - periodically check if our wi-fi connection is up and running?

You need the following permission to get status view source print? 1 <uses-permission android:name="android.permission.INTERNET"></uses- permission> 2 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses- permission>
My application needs to perform some activities in background (like interacting with the network and check the location and some other stuff), having or not the main activity visible. Which is the best way to achieve this? Should I write a service for each kind of job? Or just one service that performs everything? I am aware that I will need to launch threads / asynctasks in any case because the service runs on the same thread of the UI, but maybe having several services is a more clear and readable structure.

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.
How would i know whether my device is connected the web or not? How can i detect connectivity? Any sample code?
View 3 Replies View RelatedIs there a way to check if our code is running in the emulator vs a real device? I'm using a Map View which requires a signing key. I'm using the signature of the eclipse debug key when running on the emulator, but this won't work when I build a release version. I think I need to have a check to see if I'm running on a real device, and set it to the real release key at that time.

View 1 Replies View RelatedI have an Eris with Android v. 2.1 and a Belkin 54g router. The phone lists my home network in its list of of wifi networks. When I press the entry, an info box says that signal strength is good and security is open. (for the purpose of trying to have my phone connect). When I press "connect," it says "Obtaining IP address." Then after a couple of minutes, it says "Unsuccessful."
My phone has connected to other WiFi networks with no problem; indeed, it has done so automatically, with no effort on my part. My router assigns IP addresses via DHCP. It also broadcasts its SSID, which the phone recognizes.
We have multiple Android phones, including my Incredible, in our house on our wireless network. Is there a way to assign a name to each phone so that they are identified on the router like computers and other devices are? Currently the Android phones just show up as "unknown" device. The Wi-Fi is secured with 128-bit encryption, so I'm not concerned with the neighbors connecting, but it would be nice to be able to see which phones are on the network at any one time.

View 6 Replies View RelatedAt work, we are networked together (not wireless), anyone can type, for example \cpu1253c$ and you are now mapped to that person's computer, you can view anything on there and they don't even know you are in their computer. So I am wondering how to hide or protect my phone when it's plugged in, just charging or as a disc drive. I could use a wall charger but when I want to do file transfers, I am not sure if anyone can access my phone (Samsung S4). I am not sure what kind of network our company is on, when I log in from home, it comes to a SSL-VPN screen, another says Sonic Wall. Today I tried the properties option in the folder I had open with my phone and there was no "no share" option that I could see
View 4 Replies View RelatedThere is 3G into Android tablet.If device (Android tablet) looses network connection, it's just impossible to connect network until resetting of the device (Android tablet). What can be changed or adjusted in /system to fix it?

I want to select preferred network operators automatically from device. After I search for it, I found following:
Code:
final int EVENT_AUTO_SELECT_DONE = 300;
Message msg = mHandler.obtainMessage(EVENT_AUTO_SELECT_DONE);
phone.setNetworkSelectionModeAutomatic(msg);
So I need an instance of class "Phone". I tried this:
Code:
String phoneFactoryName = "com.android.internal.telephony.PhoneFactory";
String phoneName = "com.android.internal.telephony.Phone";
Class phoneFactoryClass = Class.forName(phoneFactoryName);
Class phoneClass = Class.forName(phoneName);
Method getDefaultPhone = phoneFactoryClass.getMethod("getDefaultPhone");
Object phoneObject = getDefaultPhone.invoke(null);
But the method "getDefaultPhone" can only called by looper.
Next I tried this:
Code:
String phoneAppName = "com.android.phone.PhoneApp";
Class phoneAppClass = Class.forName(phoneAppName);
Method getInstanceMethod = phoneAppClass.getMethod("getInstance");
Object phoneObject = getInstanceMethod.invoke(null);
But I get a ClassNotFoundException.
While using network provider for location updates, I found that it is the same time that I set on my device. Can it not be that provided by network as it goes when it is GPS. Or if network provider cannot provide time , then atleast location.getTime() should return 0 instead of device time. Is there any way to avoid device time, as I want to distinguish it.
View 1 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 trying to determine the most accurate location of a device, in the shortest time possible.I am storing the data as a geopoint, and have it displayed on a mapview.The last time I activated the GPS on my device and let it get a location lock, i was approx 80 miles from where I am now.I have a location manager setup and a location listener.If I do this, I get NULL. myLocOverlay = new MyLocationOverlay(this, mapView); GeoPoint test = myLocOverlay.getMyLocation(); but in the next couple of lines; myLocOverlay. enableMyLocation(); mapView.getOverlays().add(myLocOverlay);With this, the overlay on the map shows the current location. It is using the Network provider, but is also attempting to get a GPS fix (it can't as I am indoors and no where near the top floor).If I construct the geopoint like this Short of getting the geopoints from both GPS and Network and then comparing them, and disregarding the GPS result if it is say 1 mile out of the Network location - i'm a bit stuck. why doesn't getMyLocation() work, shouldnt that return the GeoPoint of what myLocOverlay is showing on the mapview?
