I have developed an application get location but i need to save it to server using aspx webpage.
I have created tables on the webpage and i need to save these lat,long to the webpagepage using the unique id as imei?
I have created a table with imei, latlong, datetime
aspx name /http://Log.aspx/
can anybody help me please I have searched many but I couldn't understand.

I am trying to get location name or address. I have successfully fetched the latitude and longitude by Google Fused Location API.
Now I want to fetch the location address (example : City name,Road no, or specific address) by using the latitude and longitude.
For this purpose I am using Google Geocoder and it works fine. But in some devices the location address returns the null value.
I searched in the net for the solution of this problem and found that some device manufacturers does not include this feature in their devices. That's why those device can't find the the address by Reverse Geocoding method. Here is the link of that information
So is there any alternative way to find the address name as string without Geoconding ?
Here is my code for fetching address by Geocoding
public static void getAddress(Context context, double LATITUDE, double LONGITUDE) {
try {
Geocoder geocoder = new Geocoder(context, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(LATITUDE, LONGITUDE, 1);
if (addresses != null && addresses.size() > 0) {
String address = addresses.get(0).getAddressLine(0); // If any additional address line present than only, check with max available address lines by getMaxAddressLineIndex()
String city = addresses.get(0).getLocality();
String state = addresses.get(0).getAdminArea();
String country = addresses.get(0).getCountryName();
String postalCode = addresses.get(0).getPostalCode();
String knownName = addresses.get(0).getFeatureName(); // Only if available else return NULL
Log.d(TAG, "getAddress: address" + address);
Log.d(TAG, "getAddress: city" + city);
Log.d(TAG, "getAddress: state" + state);
Log.d(TAG, "getAddress: postalCode" + postalCode);
Log.d(TAG, "getAddress: knownName" + knownName);
}
} catch (IOException e) {
e.printStackTrace();
}
return;
}
Use this its working for me
public class LocationAddress {
private static final String TAG = "LocationAddress";
private static String area = null;
public static void getAddressFromLocation(final double latitude, final double longitude,
final Context context, final Handler handler) {
Thread thread = new Thread() {
#Override
public void run() {
Geocoder geocoder = new Geocoder(context, Locale.getDefault());
String result = null;
try {
List<Address> addressList = geocoder.getFromLocation(
latitude, longitude, 1);
if (addressList != null && addressList.size() > 0) {
Address address = addressList.get(0);
StringBuilder sb = new StringBuilder();
for (int i = 0; i < address.getMaxAddressLineIndex(); i++) {
sb.append(address.getAddressLine(i)).append("\n");
}
area = address.getSubLocality();
sb.append(address.getLocality()).append("\n");
sb.append(address.getPostalCode()).append("\n");
sb.append(address.getCountryName());
result = sb.toString();
}
} catch (IOException e) {
Log.e(TAG, "Unable connect to Geocoder", e);
} finally {
Message message = Message.obtain();
message.setTarget(handler);
if (result != null) {
message.what = 1;
Bundle bundle = new Bundle();
/*result = "Latitude: " + latitude + " Longitude: " + longitude +
"\n\nAddress:\n" + result;*/
bundle.putString("address", result);
bundle.putString("area",area);
message.setData(bundle);
} else {
message.what = 1;
Bundle bundle = new Bundle();
/* result = "Latitude: " + latitude + " Longitude: " + longitude +
"\n Unable to get address for this lat-long.";*/
bundle.putString("address", result);
bundle.putString("area",area);
message.setData(bundle);
}
message.sendToTarget();
}
}
};
thread.start();
}
}
To call this in your Activity use
LocationAddress locationAddress = new LocationAddress();
locationAddress.getAddressFromLocation(latitude,longitude,
getApplicationContext(), new GeocoderHandler());
GeocoderHandler
private class GeocoderHandler extends Handler {
#Override
public void handleMessage(Message message) {
String locationAddress = null;
String area = null;
switch (message.what) {
case 1:
Bundle bundle = message.getData();
locationAddress = bundle.getString("address");
area = bundle.getString("area");
break;
default:
locationAddress = null;
}
if(locationAddress != null)
locationAddress=locationAddress.replaceAll("[\r\n]+", " ");
Log.d("===========>>>",area);
Log.d("===========>>>>",locationAddress);
}
}
I have found this solution: here to get the location name but I don't know how to display it in my textView:
LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
String provider = locationManager.getBestProvider(new Criteria(), true);
Location locations = locationManager.getLastKnownLocation(provider);
List<String> providerList = locationManager.getAllProviders();
if(null!=locations && null!=providerList && providerList.size()>0){
double longitude = locations.getLongitude();
double latitude = locations.getLatitude();
Geocoder geocoder = new Geocoder(getApplicationContext(), Locale.getDefault());
try {
List<Address> listAddresses = geocoder.getFromLocation(latitude, longitude, 1);
if(null!=listAddresses&&listAddresses.size()>0){
String _Location = listAddresses.get(0).getAddressLine(0);
}
} catch (IOException e) {
e.printStackTrace();
t.append("\n " + ????? + " ");
}
}
The t is the textView
You have the name address in the String _Location. Therefore, you could set the value of TextView in the try block.
try {
List<Address> listAddresses = geocoder.getFromLocation(latitude, longitude, 1);
if(null!=listAddresses&&listAddresses.size()>0){
String _Location = listAddresses.get(0).getAddressLine(0);
}
t.setText(_Location);
}
Further Infomation
String address1 = listAddresses.get(0).getAddressLine(0);
String city = listAddresses.get(0).getLocality();
String state = listAddresses.get(0).getAdminArea();
String country = listAddresses.get(0).getCountryName();
String postalCode = listAddresses.get(0).getPostalCode();
String knownName = listAddresses.get(0).getFeatureName();
t.setText(address1 + " " + city + "\n" + state + " " + postalCode);
You could use this code to get further information about the adress
Does someone know how to get gsm information in android? Information like BCCH (Broadcast Control Channel) and BCIS (Base Station Identity Code). I already got the LAC (Location Area Code) and CID (Cell ID). I know that is a low level information but does someone know to get those information? I am having a hard time researching and i don't have an idea about cellular network. Please Help thanks :)
Here is function which gives you complete information of gsm network.
just Call with context from your activity

mcc = Integer.parseInt(networkOperator.substring(0, 3));
mnc = Integer.parseInt(networkOperator.substring(3));
}
String SimNumber = telephonyManager.getLine1Number();
String SimSerialNumber = telephonyManager.getSimSerialNumber();
String countryISO = telephonyManager.getSimCountryIso();

You can use requestLocationUpdates of LocationManager Class
requestLocationUpdates (long minTime, float minDistance, Criteria
criteria, PendingIntent intent)
So, the first param you can specify as 30 mins according to your requirement.
To keep track of hours elapsed, you can have something like :
var1 = System.CurrentTimeMillis(); //Get time when service started
In onLocationChanged()
var2 = System.CurrentTimeMillis();
Now calculate var2-var1 to get elapsed time. if >17 hrs, removeUpdates from locationManager
I have a similar project going on, I am using a Service for this, fired by an AlarmManager.
Check here for more info.
The approach provided by Schaemelhout and the approach taken by library referred to in the comments is the only workable solution I have found.
Using an AlarmManager to wake your service guarantees the service is periodically invoked/restarted. This serves to counteract any power saving actions that the OS/phone might hit your service with in the mean time.
Registering a location listener from your alarm BroadcastReceiver wakes up the GPS (the GPS would not normally be running if the phone is asleep). In your alarm BroadcastReceiver you will need to take and hold a WakeLock and stay awake until results are passed back to the listener.
The down side to this approach is that it takes a while for a location to be available and the accuracy may be bad. Your service might have to wait a while until acceptable accuracy is achieved (the Location accuracy value can be wrong, so it might be be best to wait for a few samples). The whole approach will need to be tuned to your required update frequency and accuracy requirements. If you need very frequent and accurate updates I suspect holding a wake-lock and keeping the GPS alive might be the only way to go.
I also tried using the lm.requestLocationUpdates() using a PendingIntent. This did faithfully wake up my service and pass it an Intent, but if the GPS was sleeping prior to the wake up the Intent lacked a location.
What i have: currently my app is only telling me the coordinates of my current location.
What i want: Get location name from coordinates fetched by gps, so that i could know where exactly i am. (Name of location)
Here is complete code from fetching long - lat to getting address:
LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
String provider = locationManager.getBestProvider(new Criteria(), true);
Location locations = locationManager.getLastKnownLocation(provider);
List<String> providerList = locationManager.getAllProviders();
if(null!=locations && null!=providerList && providerList.size()>0){
double longitude = locations.getLongitude();
double latitude = locations.getLatitude();
Geocoder geocoder = new Geocoder(getApplicationContext(), Locale.getDefault());
try {
List<Address> listAddresses = geocoder.getFromLocation(latitude, longitude, 1);
if(null!=listAddresses&&listAddresses.size()>0){
String _Location = listAddresses.get(0).getAddressLine(0);
}
} catch (IOException e) {
e.printStackTrace();
}
}
You can us the GeoCoder which is available in android.location.Geocoder package. The JavaDocs gives u full explaination. The possible sample for u.
List<Address> list = geoCoder.getFromLocation(location
.getLatitude(), location.getLongitude(), 1);
if (list != null & list.size() > 0) {
Address address = list.get(0);
result = address.getLocality();
return result;
The result will return the name of the location.
Here i am given a single just pass the latitude and longitude in this function then you got all the information related to this latitude and longitude.
public void getAddress(double lat, double lng) {
Geocoder geocoder = new Geocoder(HomeActivity.mContext, Locale.getDefault());
try {
List<Address> addresses = geocoder.getFromLocation(lat, lng, 1);
Address obj = addresses.get(0);
String add = obj.getAddressLine(0);
GUIStatics.currentAddress = obj.getSubAdminArea() + ","
+ obj.getAdminArea();
GUIStatics.latitude = obj.getLatitude();
GUIStatics.longitude = obj.getLongitude();
GUIStatics.currentCity= obj.getSubAdminArea();
