How do I log the GPS accuracy in meters with getAccuracy() in Android?
The following is my code. When I run it, I get a build error. I added in the getAccuracy() method, but strangely it returns an error.
package com.example.yires.locationdemo;
import android.Manifest;
import android.accounts.AccountAuthenticatorResponse;
import android.content.Context;
import android.content.pm.PackageManager;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.support.annotation.NonNull;
import android.support.v4.app.ActivityCompat;
import android.support.v4.content.ContextCompat;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
public class MainActivity extends AppCompatActivity {
LocationManager locationManager;
LocationListener locationListener;
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);
}
}
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
locationListener = new LocationListener() {
#Override
public void onLocationChanged(Location location) {
Log.i("Location",location.toString());
Log.i("GetAccuracy",location.getAccuracy());
}
#Override
public void onStatusChanged(String s, int i, Bundle bundle) {
}
#Override
public void onProviderEnabled(String s) {
}
#Override
public void onProviderDisabled(String s) {
}
};
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION},1);
} else {
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);
}
}
}
I am a beginner in Android, so would appreciate any code help or explanation. Thank you once again.
To log float value, use String.valueOf(location.getAccuracy());
Log.i("HasAccuracy", String.valueOf(location.getAccuracy());

Is there a way to get latitude longitude constantly updated without running Google MAPS app in emulators background. I would like to receive updated latitude and longitude from the users device. The code gets the latitude and longitude only after I change between apps or setup a driving route and press the button. I would like to update every X amount of time.

I am working on an app that has a method called PostCar that when called should create a databasereference and add a child to My Firebase Consoles Lender table a child that contains the user's id and location. The problem is the location keeps getting marked as null. The code in my PostCar method that reads "geoFire.setLocation(userId,new GeoLocation(mlastlocation.getLatitude(),mlastlocation.getLongitude()));" keeps throwing the error "attempt to invoke virtual method 'double android.location.location.getlatitude()' on a null object reference". The devices location is on and I check for location permissions. Here is the code below.

Are you testing this with the Xcode IOS simulator? The simulator can't actually access your real location so when queried it will return null unless specified manually (Features tab, Location, Custom Location.)
The reason fusedapi was not working for me is because i was not using a google maps project. So I overode onlocatiochanged instead. This worked for me, but you have to extend onlcationchanged and googleapi

I get this when I try to Send new location to phone from emulator, virtual phone (Nexus). Have tried different Coords, and also restarting both Android studio, phone, and computer.
What I expect is the Log.d (tried them all), but that doesn't get output even if I run it in debug mode.
