GPS data on android phone

I am building an app which can detect location change by reading GPS data. I am observing the change on longitude and latitude to detect the location change. But my app is only working when I go far away. The value I get on latitude and longitude is only upto two decimal points.Is there any way to get more precise data of latitude and longitude in android? I want get the value upto 7 or 8 decimal point. My code is given below-
if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
Log.d("GPS ", "ON");
mysample = mysample + "GPS = 1 \n";
Location location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
double latitude = 0;
double longitude = 0;
if (location != null) {
latitude = location.getLatitude();
longitude = location.getLongitude();
}
if ( plat != latitude || plong != longitude) {
Log.d("GPS MOVING ", "ON");
mysample = mysample + "GPS MOVING = 1 \n";
Log.d("GPS CORDINATE ", "" + longitude + "" + latitude);
plat = latitude;
plong = longitude;
} else {
Log.d("GPS MOVING ", "OFF");
mysample = mysample + "GPS MOVING = 0 \n";
Log.d("GPS CORDINATE ", "" + longitude + "" + latitude);
}
} else {
Log.d("GPS ", "OFF");
mysample = mysample + "GPS = 0 \n";
Log.d("GPS MOVING ", "OFF");
mysample = mysample + "GPS MOVING = 0 \n";
}

Getting precise data of latitude and longitude is a nice idea however, setting location results to 7 or 8 decimal points is practically used in surveying purposes, as shown in Decimal degrees in Wikipedia.
A perfect explanation for this concern can be found in this thread.

How to find distance between two longitude location? [duplicate]

This question already has answers here:
How to calculate distance between two locations using their longitude and latitude value
(14 answers)
Closed 6 years ago.
I want your help to calculate the distance b/t two longitudes. Can anybody tell me how to find the distance? I am new on Android studio. I want to find the distance in my app. Destination address in defined by mlat and mlong and current address is calculated through GPS whose value goes in longitude and latitude.
My code is:
double mlat =30.726030;
double mlong=76.759268;
imgButton1 =(ImageButton)findViewById(R.id.imageButton1);
mgButton1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Location gpsLocation = appLocationService.getLocation(LocationManager.GPS_PROVIDER);
if (gpsLocation != null) {
double latitude = gpsLocation.getLatitude();
double longitude = gpsLocation.getLongitude();
String result = "Latitude: " + gpsLocation.getLatitude() +
" Longitude: " + gpsLocation.getLongitude();
tvAddress.setText(result);
} else {
showSettingsAlert();
}
}
});
Tell me how to find the distance between two longitudes and latitudes.

Use the distanceBetween method to calculate distance:
Location.distanceBetween(double startLatitude, double startLongitude, double endLatitude, double endLongitude, float[] results)

get latitude,longitude and insert url

i got the latitude and longitude use Location.
and save in
private double mLatitude;
private double mLongitude;.
mLatitude = location.getLatitude();
mLongitude =location.getLongitude();
locationMg =(LocationManager)getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_COARSE);
criteria.setPowerRequirement(Criteria.POWER_LOW);
criteria.setAltitudeRequired(false);
criteria.setBearingRequired(false);
criteria.setSpeedRequired(false);
criteria.setCostAllowed(true);
String bestProvider = locationMg.getBestProvider(criteria, true);
Location location = locationMg.getLastKnownLocation(bestProvider);
if(location != null){
Toast.makeText(this,"Latitude" +location.getLatitude()+"\n"+"Longitude"+location.getLongitude(), 0).show();
mLatitude = location.getLatitude();
mLongitude = location.getLongitude();
}
and
private String url ="http://api.openweathermap.org/data/2.5/weather?lat="+mLatitude+"&lon="+mLongitude+"&mode=xml";
I saw LogCat After running this code .
However, the value of the longitude and latitude of 0.0 came out.
Why is it?
Is it because the string type url??????????????
and Latitude and longitude should only type is double.
Do change the url?
help.
I do not know what to do.

From the documention
If the provider is currently disabled, null is returned from getLastKnownLocation()
check whether location object is null.
Register for location updates using requestLocationUpdates (long minTime, float minDistance, Criteria criteria, PendingIntent intent)

Maybe you are not defining url after location is known. Put ir here:
if(location != null){
Toast.makeText(this,"Latitude" +location.getLatitude()+"\n"+"Longitude"+location.getLongitude(), 0).show();
mLatitude = location.getLatitude();
mLongitude = location.getLongitude();
url ="http://api.openweathermap.org/data/2.5/weather?lat="+mLatitude+"&lon="+mLongitude+"&mode=xml";
}

Get current location using gps not using Lastknownlocation

I have an application where I need to get my current location I am using
setNlocation(locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER));
Because of this I am getting last location I also try to use
#Override
public void onLocationChanged(Location loc)
{
glat = loc.getLatitude();
glng = loc.getLongitude();
Toast.makeText( getApplicationContext(),"GPS Lat:" + glat + "GPS Lng" + glng,Toast.LENGTH_LONG).show();
}
but that GPS icon is blinking and blinking and blinking .(Not getting GPS Lat Lng of current position)

Here is small application with step by step description to gets current locations GPS co-ordinate
locationMangaer.requestLocationUpdates(LocationManager.GPS_PROVIDER, 5000, 10,locationListener);

How to get the latitude and longitude or gps data quickly while we are indoor in an android phone?

I'm trying to get the latitude and longitude information from an android phone through GPS, when i'm outdoor or under the sky directly i'm able to get the values instantly but when i'm indoor or inside a room its taking more than a minute to get the values. Can anyone help me in getting this values fastly when I'm using my app inside a room.
I'm using the following code in getting the values:
LocationManager locManager;
locManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000L,500.0f,
locationListener);
Location location = locManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
and
private final LocationListener locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
EditText myLocationText = (EditText)findViewById(R.id.editText1);
EditText myLocationText1 = (EditText)findViewById(R.id.editText2);
String latString = "";
String LongString = "";
if (location != null) {
double lat = location.getLatitude();
double lng = location.getLongitude();
latString = "" + lat;
LongString ="" + lng;
} else {
latString = "No location found";
LongString = "No location found";
}
myLocationText.setText(""+ latString);
myLocationText1.setText(""+ LongString);
}
Is there any other way in getting the GPS values other than using LocationManager??

You can get the last known location, and it's quite fast:
/**
* Gets the last known location.
*
* #param locationManager the location manager
* #return the last known location
*/
public static Location getLastKnownLocation(LocationManager locationManager)
{
Location bestResult = null;
float bestAccuracy = 10000;
long bestTime = 0;
List<String> matchingProviders = locationManager.getAllProviders();
for (String provider: matchingProviders) {
Log.d("LOCATION", "Provider: " + provider);
Location location = locationManager.getLastKnownLocation(provider);
Log.d("LOCATION", "Location found? "+ (location==null?"NO":"YES"));
if (location != null) {
float accuracy = location.getAccuracy();
long time = location.getTime();
Log.d("LOCATION", "Acc: "+ String.valueOf(accuracy) + " -- Time: " + String.valueOf(time));
if ((time > minTime && accuracy < bestAccuracy)) {
bestResult = location;
bestAccuracy = accuracy;
bestTime = time;
}
else if (time < minTime &&
bestAccuracy == Float.MAX_VALUE && time > bestTime){
bestResult = location;
bestTime = time;
}
}
}
Log.d("LOCATION", "BEST FOUND? "+ (bestResult==null?"NO":"YES"));
return bestResult;
}

You can get the last known location of the device using the following method in LocationManager, this is the location that has been last found system-wide.
This method is the key:
Location lastKnownLocation = locationManager.getLastKnownLocation(locationProvider);
See for more details Obtaining User Location

If you are indoors, you would be better of using LocationManager.NETWORK_PROVIDER as you are unlikely to get a signal inside. You could also use getLastKnownLocation(), but this may be non existent or out of date.

If you want get position in a room, gps provider is slowly. You can try changing:
locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000L,500.0f,
locationListener);
Location location = locManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
By:
locManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,1000L,500.0f,
locationListener);
And you will receive location in 'public void onLocationChanged(Location location)' method.

I used Network provider to fetch the Co-Ordinates and it is always much faster inside the house in living room. But when I try the same in the Basement area, it doesn't fetch the coordinates at all though I waited almost couple of minutes.
Note: I could able to make a call from basement area and I am also able to browse as well..
