I am not getting the lat and long in samsung S3.In other devices my code is working fine and getting the proper lat and long.Below is my code to get the lat and long.
public class MainActivity extends Activity {
TextView textView1;
Location currentLocation;
double currentLatitude,currentLongitude;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView1 = (TextView) findViewById(R.id.textView1);
findLocation();
}
public void findLocation() {
LocationManager locationManager = (LocationManager) this
.getSystemService(Context.LOCATION_SERVICE);
LocationListener locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
updateLocation(location,currentLatitude,currentLongitude);
Toast.makeText(
MainActivity.this,
String.valueOf(currentLatitude) + "\n"
+ String.valueOf(currentLongitude), 5000)
.show();
}
public void onStatusChanged(String provider, int status,
Bundle extras) {
}
public void onProviderEnabled(String provider) {
}
public void onProviderDisabled(String provider) {
}
};
locationManager.requestLocationUpdates(
LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
}
void updateLocation(Location location,double currentLatitude,double currentLongitude) {
currentLocation = location;
this.currentLatitude = currentLocation.getLatitude();
this.currentLongitude = currentLocation.getLongitude();
textView1.setText(String.valueOf(this.currentLatitude) + "\n"
+ String.valueOf(this.currentLongitude));
}
}
In above code the onLocationChanged() method is not executing in S3 and the same code is not working in Samsung S3 device.In other devices it working fine.I am getting the correct lat and long in other devices.Please help me to sort out this problem..

I have trouble getting latitude and longitude on Itel A16 device (Android 8.1.0). I have used the following code, which works fine based on my test on other devices and emulators. But not on Itel A16 I would appreciate any help to fix this so that the Toast can show device location.
LocationManager locationManager = (LocationManager) getActivity().getSystemService(getContext().LOCATION_SERVICE);
LocationListener locationListener = new LocationListener() {
#Override
public void onLocationChanged(Location location) {
double MyLat = location.getLatitude();
double MyLong = location.getLongitude();
Toast.makeText(getContext(), " latitude: " + MyLat + " longitude: " + MyLong, Toast.LENGTH_LONG).show();
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
#Override
public void onProviderEnabled(String provider) {
}
#Override
public void onProviderDisabled(String provider) {
}
};
//Location test
if (checkSelfPermission(getContext(), Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && checkSelfPermission(getContext(),Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
}
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);
I fixed the issue with FusedLocationProviderClient , following Android Developers instructions

Any sugestion how I can do it? I read about the Service - GPS work in background, but how do it with TextView?
I am developing a small android application in which I want to find out the user's current location by using the network provider. I tried this in following ways but it's not giving me any output :
networklocationManager = (LocationManager) this
.getSystemService(Context.LOCATION_SERVICE);
// Define a listener that responds to location updates
LocationListener networklocationListener = new LocationListener() {
public void onLocationChanged(Location location) {
Log.i("********************************",
"this is my network location " + location);
String Location_text = "NETWORK LOCATION latitude:"
+ location.getLatitude() + " longitude:"
+ location.getLatitude();
network_location.setText(Location_text);
}
public void onStatusChanged(String provider, int status,
Bundle extras) {}
public void onProviderEnabled(String provider) {}
public void onProviderDisabled(String provider) {}
};
// Register the listener with the Location Manager to receive location
// updates
networklocationManager
.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0,
networklocationListener);
I gave permissions in my manifest file like this
<uses-permission
android:name="android.permission.INTERNET" />
<uses-permission
android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission
android:name="android.permission.ACCESS_FINE_LOCATION" />
Is there any thing which I am missing ? Is this the correct way? Need help. Thank you...

Make sure you enable Location Services in Settings! That should be the problem. It might be disabled (and this setting will usually be found in Location and Security in Settings)
Let me know if it works!
Is your network provider enabled?
boolean network_enabled;
try {
network_enabled = locManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
} catch(Exception ex) {
ex.printStackTrace();
}
I hope this part of the code will help you extracted from vogella.

Please help me out from this issue...
I adapt where am i tutorial.. hope it would help
p.s. I write it without testing .. technically,it would work.. i guess

I want to develope an app in which when i start the app it will first give me Latitude and Longitude of my current location. Here is my code:
LocationListener locLis=new LocationListener() {
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {}
#Override
public void onProviderEnabled(String provider) {}
#Override
public void onProviderDisabled(String provider) {}
#Override
public void onLocationChanged(Location location)
{
// TODO Auto-generated method stub
Double lat=location.getLatitude();
Double lon=location.getLongitude();
Log.i("Latitude=="+lat,"=="+lon);
}
};
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates( LocationManager.GPS_PROVIDER,0,0, locLis);
I use ACCESS_FINE_LOCATION in the manifest file.
But when i start the app there is no latitude and longitude it found. Why? If i change the location's latitude longitude from the command prompt then it will show the updated latitude and longitude. Please anyone help me
Take this code and enjoy
public void find_Location(Context con)
{
Log.d("Find Location", "in find_location");
this.con=con;
String location_context = Context.LOCATION_SERVICE;
locationManager = (LocationManager)con.getSystemService(location_context);
List<String> providers = locationManager.getProviders(true);
for (String provider : providers)
{
locationManager.requestLocationUpdates(provider, 1000, 0,new LocationListener()
{
public void onLocationChanged(Location location) {}
public void onProviderDisabled(String provider){}
public void onProviderEnabled(String provider){}
public void onStatusChanged(String provider, int status,Bundle extras){}
});
Location location = locationManager.getLastKnownLocation(provider);
if (location != null)
{
latitude = location.getLatitude();
longitude = location.getLongitude();
addr=ConvertPointToLocation(latitude,longitude);
String temp_c=SendToUrl(addr);
}
}
}
public String ConvertPointToLocation(double pointlat,double pointlog) {
String address = "";
Geocoder geoCoder = new Geocoder(con,
Locale.getDefault());
try {
List<Address> addresses = geoCoder.getFromLocation(pointlat,pointlog, 1);
if (addresses.size() > 0) {
for (int index = 0; index < addresses.get(0)
.getMaxAddressLineIndex(); index++)
address += addresses.get(0).getAddressLine(index) + " ";
}
}
catch (IOException e) {
e.printStackTrace();
}
return address;
}
Your code is set to display the location only when it changes.
I think in order to display it when the app starts, you should try putting it in onProviderEnabled() or some other initialization routine.
You should do like this
public class MyLocationListener implements LocationListener
{
#Override
public void onLocationChanged(Location loc)
{}
#Override
public void onProviderDisabled(String provider)
{}
#Override
public void onProviderEnabled(String provider)
{}
#Override
public void onStatusChanged(String provider, int status, Bundle extras)
{
}
}
mlocManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
mlocListener = new MyLocationListener();
mlocManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, 0, 0, mlocListener);
