i have a problem with my app getting my GPS position.
first of all i have the two things in my manifest:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
then i have a code like this for the location:
LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
LocationListener locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
// Called when a new location is found by the network location provider.
makeUseOfNewLocation(location);
}
public void onStatusChanged(String provider, int status, Bundle extras) {}
public void onProviderEnabled(String provider) {}
public void onProviderDisabled(String provider) {}
};
locationManager.requestLocationUpdates(0l, 0f, new Criteria(), locationListener, Looper.getMainLooper());
now the strange thing:
when i have wifi enabled and i'm in my network, i get a position. If i have only GPS enabled i dont get my position. even i dont see the gps icon at the top of the phone which shows when a app makes use of my gps.
what is wrong here?
For GPS:
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);
For Network:
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);

I don't want to use service which is continuously running in background ! Actually in my project user will send SMS command from any smartphone to his/her misplaced smartphone.My app will detect that particular "SMS command" and in return it will send the current location of misplaced mobile.
can it be done through intent service ? I m damn confused ... Its single time operation how to perform it efficiently ... ?
by using NETWORK_PROVIDER getting geolocation
LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
// Define a listener that responds to location updates
LocationListener locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
// Called when a new location is found by the network location provider.
makeUseOfNewLocation(location);
}
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
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
and add this permission in manifest.xml
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
I am trying to use the following code snippet on an Android app with targetSdkVersion = 22. (source)
// Acquire a reference to the system Location Manager
LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
// Define a listener that responds to location updates
LocationListener locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
// Called when a new location is found by the network location provider.
System.out.println(location);
}
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
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);
In my manifest permissions, I have:
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-feature android:name="android.hardware.location.gps" />
<uses-feature android:name="android.hardware.location.network" />
Under Settings -> Location, my phone (Galaxy S8) has three locating methods:
High accuracy, Battery Saving and Phone only. This code successfully works for the first 2 locating methods but not Phone only.
Phone only says it "Uses GPS to estimate your location", so I would expect using the GPS_PROVIDER would be sufficient to get location changes.
Why isn't it working?
How can I get continuous geo-location of android device programmatically ?
I'm having troubles of getting position coordinates continuously of android device and show the navigation move according to the geolocation.
According to Android documentation :
// Acquire a reference to the system Location Manager LocationManager locationManager = (LocationManager)
this.getSystemService(Context.LOCATION_SERVICE);
// Define a listener that responds to location updates
LocationListener locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
// Called when a new location is found by the network location provider.
makeUseOfNewLocation(location);
}
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
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,
> 0, 0, locationListener);

In Android if LocationServices is disabled, is there any way that I can get the current location through wifi/network. I know there is one way of showing the user a popup to change his LocationSettings , but I don't want to show the popup.
So is there any way of getting the current location even if LocationServices is disabled ?
use LocationManager.NETWORK_PROVIDER instead of LocationManager.GPS_PROVIDER
The entire code and how to use is given here :
http://developer.android.com/guide/topics/location/strategies.html
// Acquire a reference to the system Location Manager
LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
// Define a listener that responds to location updates
LocationListener locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
// Called when a new location is found by the network location provider.
makeUseOfNewLocation(location);
}
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
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
Yes of course, you can use:
// let Android select the right location provider for you
String myProvider = locationManager.getBestProvider(myCriteria, true);

I am getting longitude=0.0 and latitude=0.0 on tablet while this is working perfectly on the phone.
I am using LocationManager.NETWORK_PROVIDER and not the GPS_PROVIDER so what could be the cause please?
Logcat output??
that's my code:
// Acquire a reference to the system Location Manager
locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
// Define a listener that responds to location updates
locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
// Called when a new location is found by the network location provider.
longitude=location.getLongitude();
latitude=location.getLatitude();
}
public void onStatusChanged(String provider, int status, Bundle extras) {}
public void onProviderEnabled(String provider) {}
public void onProviderDisabled(String provider) {}
};
//Or use LocationManager.GPS_PROVIDER
String locationProvider = LocationManager.NETWORK_PROVIDER;
// Register the listener with the Location Manager to receive location updates
locationManager.requestLocationUpdates(locationProvider, 0, 0, locationListener);
Location lastKnownLocation = locationManager.getLastKnownLocation(locationProvider);
if(lastKnownLocation!=null){
longitude=lastKnownLocation.getLongitude();
latitude=lastKnownLocation.getLatitude();
}
Check out Location settings inside your device settings. This seems not a problem with your code, but your device settings. In my Ginger bread, it's as:
Settings -> Location&security -> Use wireless networks
