In my application, I want to collect the surrounding cell ID and LAC on my Android phone (to estimate the location).I use the telephonyManager.getNeighboringCellInfo() function which returns a list of NeighboringCellInfo.
If the phone has enabled the option "use only 2G networks" I receive the correct list but if this option is not enabled (connecting also on 3G networks), the NeighboringCellInfo has "-1" for cell ID and LAC for the whole list.
why 3G networks provides less information than 2G ? Is there some technical reason ? Can I still get the cell details on 3G ?
I need some advices about the Android OS and application.i wonder if the Android OS is able to push network connecting status to applications.(I found applications can get a network connecting status from android OS. But I can't find reverse cases.)However, I am thinking android OS may push network connecting status to applications.when application is installed on android os, is it possible to register something for monitoring phone's network status on android os.Because I want my application can receive phone's network status from android os.(not by asking directly to android os.) It means: when phone's network status changes, does android os automatically informs phone's network status to application?I'm sorry my English writing is bad TT;

Is it possible to know if the application is using coarse or fine grained location information? Is it possible to detect which type of localization is being provided, i.e. gps vs. wifi?

View 2 Replies View RelatedMy program is targeting Android 1.5. I would like to retrieve system information about the device itself. I have found very few helpful classes by searching the APIs. the best I've found so far is the Runtime class and a few Build.* system properties.
I would like to be able to get information like the total amount of memory on the device, the amount of free memory (which I do not know if the Runtime class is actually giving me, since it specifically refers to memory available to the JVM) along with information about the processor.
Is this information available, and if so, where can I find it?
The most important things i want to know are the device type, the os version, if it has a hardware keyboard and maybe the screen resolution. but if you know other useful debug information.

I use iCal on the Touch and iCal on my Mac as well as the address book on both everyday and as a Mobile Me user, my two devices sync so everything is mirrored and up to date. I also HATE AT&T for their terrible signal strength and coverage and have been a loyal Verizon customer for many years and this is why I don't have an iPhone. Okay, all that being said, is there an easy way to still use everything I love and rely on with my Mac (the calender and address book, mainly) and easily sync all of my existing information and future info to an Android based device? How easy is it to use an Android device with a Mac? I don't want to have to manually re-enter my entire address book into a new device.

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 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?
Specifications Android tablet:
Allwinner A10
Built-in 3G
7"
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?

View 1 Replies View RelatedI 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'm wondering if, with the G1, it's possible to force the network traffic to pass through the Wifi or through the Cell GSM network. I need to force an application to connect through the tower network to get some login information. Is this possible? Anyone have any ideas as to how this would be possible? I'm trying to accomplish this inside an app with the Android SDK (Sorry I wasn't more clear about that originally)
