I Have This Creepy problem. i am trying to get the location of my emulator. it working fine when i get the location of my emulator. but when i change my location coordinates nothing happens. gps is working fine.
Here is my code

boolean gpsEnabled;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tvStatus = (TextView) findViewById(R.id.textView1);
lm = (LocationManager) getSystemService(LOCATION_SERVICE);
if (lm.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
Log.d("", "GPS is Active");
Location l = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
tvStatus.setText(l.getLatitude()+" , "+l.getLongitude());
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0,
new LocationListener() {
#Override

Samsung phones have this problem. There is hack to this. You need to kick the locationmanager on the butt to get the latest location from the maps cache.
God.locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0,
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(final Location location) {
}
});
currentLocation = God.locationManager
.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
Call getLastKnownLocation after kicking the requestLocationUpdates with 0's.
It happens with emulators, try rebooting the emulator.
Or, close both eclipse and emulator and start both again

I'd like to get Geo location by using GPS provider. So my code will be like this
import android.location.Criteria;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.provider.Settings;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends Activity {
LocationManager lm;
TextView textLatitude, textLongitude;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textLatitude = (TextView)findViewById(R.id.textLatitude);
textLongitude = (TextView)findViewById(R.id.textLongitude);
lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
/* Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_FINE);
criteria.setAltitudeRequired(false);
criteria.setBearingRequired(false);*/
}
public void onResume() {
super.onResume();
setup();
}
public void onStart() {
super.onStart();
boolean gpsEnabled, networkEnabled;
gpsEnabled = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
Log.d("LocationService","GPS Status: "+gpsEnabled);
if(!gpsEnabled) {
networkEnabled =
lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
if(!networkEnabled) {
Intent intent =
new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(intent);
}
}
}
public void onStop() {
super.onStop();
lm.removeUpdates(listener);
}
public void setup() {
lm.removeUpdates(listener);
String latitude = "Unknown";
String longitude = "Unknown";
Location gpsLocation = requestUpdatesFromProvider(
LocationManager.GPS_PROVIDER, "GPS not supported");
if(gpsLocation != null) {
Log.d("Location Service","GET FROM GPS");
latitude = String.format("%.7f", gpsLocation.getLatitude());
longitude = String.format("%.7f", gpsLocation.getLongitude());
}
textLatitude.setText(latitude);
textLongitude.setText(longitude);
}
public Location requestUpdatesFromProvider(final String provider
, String error) {
Location location = null;
if (lm.isProviderEnabled(provider)) {
lm.requestLocationUpdates(provider, 0, 0, listener);
Log.d("LocationService","Requesting...");
location = lm.getLastKnownLocation(provider);
//Log.d("LocationSerivce", "Geo :"+location.getLatitude());
} else {
Toast.makeText(this, error, Toast.LENGTH_LONG).show();
}
return location;
}
public LocationListener listener = new LocationListener() {
public void onLocationChanged(Location location) {
textLatitude.setText(String.format("%.7f", location.getLatitude()));
textLongitude.setText(String.format("%.7f",location.getLongitude()));
}
public void onProviderDisabled(String provider) { }
public void onProviderEnabled(String provider) { }
public void onStatusChanged(String provider
, int status, Bundle extras) { }
};
}
The result is ... IT DOESN'T WORK. What have I done wrong?
I've also added permission to manifest file already.

I search a lot from Internet and I got that it'll work if I combine with Network provider and I have to use internet to get my location. This is not what I want.
I want to get Location from GPS only because I'll use for offline application.
Could you give me any great suggestion. I'll thanks a lot
I want to pop up the alert dialog on location change through service. Here i have attached my manifest , Service and broadcastReciever codes.
In the console it is giving that .apk has been installed.
But i'm not getting any toast or alertdialog.
PLease correct me if i'm wrong.
Thanks.

create an Activity and and register receiver in this activity and start service from this activity and use alert dialog in activity class
i have modified your code and its working fine with my testing mobile device (sony xperia)

still have any doubts for Receiver,Service and GPS classes let me know!!
or even your can check Start Service from Broadcast Receiver and Get Current Location links for details. hope it helps!!
I'm trying to create a program for android that constantly (every minute) gets the gps location and then sends it to my server at home (so that i always know where my phone is).
I created a gui with a start-button which starts the service:
start.setOnClickListener(new View.OnClickListener() {
synchronized public void onClick(View v) {
startService(new Intent(GpsTest2.this, GTService.class));
}
});
Then my service is declared like this:
public class GTService extends Service implements LocationListener {
}
This GTService has a method for retrieving the data:
public void onLocationChanged(Location location) {
}
#Override
public void onCreate() {
super.onCreate();
LocationManager locMgr = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locMgr.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, interval * 1000, minDist, this);
}
In AndroidManifest.xml I have:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<service android:name=".GTService">
</service>
This doesn't seem to work: no data is logged.
What am I doing wrong here?
Your code seems to be working fine except this,
You are using LocationManager.NETWORK_PROVIDER
locMgr.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, interval * 1000, minDist, this);
Where as it should be LocationManager.GPS_PROVIDER
locMgr.requestLocationUpdates(LocationManager.GPS_PROVIDER, 2 * 1000, 10, locationListener);
Hope this will surely do for you. Thanks.
The location from Network provider is not accurate. PLease use GPS instead. If you really want to user Network only then I would recomond to set minDistance param as 0
The following should work fine,
Manifest :
<uses-sdk
android:minSdkVersion="8"

Whenever I call initMyLocation, the app crashes (bot on emulator and device). Same happens when I try to implement a MiniMap. I do exactly the same as in the SampleExtensive example from the Osmdroid repository. What am I doing wrong?

In your setMap(), you never set
myMap = map;
So in initMyLocation, you are passing null for the pMapView parameter.
to use location you must have the following in your AndroidManifest.xml :
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
