I am trying to get user's location but it seems like onLocationUpdate is never triggered, I tried to run this app on multiple devices same result.
I tried to Google before posting here, couldn't find any solution. And, Android Internet,GPS COARSE and GPS FINE permissions added in manifest file.
Here's my whole activity code
public class AnotherActivity extends AppCompatActivity {
LocationManager locationManager;
LocationListener locationListener;
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
// Checking if we got permission
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_nearby_restaurants);
locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
locationListener = new LocationListener() {
#Override
public void onLocationChanged(Location location) {
Toast.makeText(NearbyRestaurants.this, location.getLatitude()+String.valueOf(location.getLongitude()), Toast.LENGTH_SHORT).show();
Log.i("Location Update!", location.toString())
}
#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{
Log.i("Checking Location","Checking Location Wait");
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);
}
}
}
Can you also try to add NETWORK_PROVIDER when requesting location
requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);

I tried to send my location via SMS, but the button doesn't work.
The button was working fine before I added the code of getting current location.
Can you please help me to fix that? I tried many solutions that I found in this website, but it doesn't work with me.
I am totally new to Android Studio, so I don't know how to write my code that it will work the way I want it.

This app is supposed to display the users current location on a map.I use the FusedLocationProviderClient class to get this work done, getting the users current known location and displaying it to the user through a Toast and on the map.
The app is working but my issue is that no map gets displayed once the app is launched, only the toast
MainActivity Code:
FusedLocationProviderClient fusedLocationProviderClient;
private static int REQUEST_CODE = 101;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(MainActivity.this) ;
fetchLastLocation();
}
private void fetchLastLocation() {
if(ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION},REQUEST_CODE);
return;
}
Task<Location> task = fusedLocationProviderClient.getLastLocation();
task.addOnSuccessListener(new OnSuccessListener<Location>() {
#Override
public void onSuccess(Location location) {
if(location!=null)
currentLocation = location;
Toast.makeText(getApplicationContext(),currentLocation.getLatitude()+ "" + currentLocation.getLongitude(),Toast.LENGTH_SHORT).show();
SupportMapFragment supportMapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.google_map);
assert supportMapFragment!=null;
supportMapFragment.getMapAsync(MainActivity.this);
}
});
}
#Override
public void onMapReady(GoogleMap googleMap) {
LatLng latLng = new LatLng(currentLocation.getLatitude(), currentLocation.getLongitude());
googleMap.addMarker(new MarkerOptions().position(latLng).title("I am here"));
googleMap.animateCamera(CameraUpdateFactory.newLatLng(latLng));
googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(latLng,15));
}

I'm just fetching the current location of the device and displaying on a TextView but the TextView does not show the results, however , it seems that the java code is fetching the location correctly but not updating the TextView as I have tried a lot relevant codes without error of location fetching.
Moreover, I am using a physical device to run the Application, not the emulator.
The recent code I've tried is as below:
public class roadSideSelection extends AppCompatActivity implements AdapterView.OnItemSelectedListener, LocationListener {
int MY_PERMISSION_LOCATION=100;
int MY_PERMISSION_ACCESS_COARSE_LOCATION=100;
protected LocationManager locationManager;
protected Context context;
TextView txtLat;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_road_side_selection);
marshmallowGPSPremissionCheck();
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED ) {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.ACCESS_COARSE_LOCATION},
MY_PERMISSION_ACCESS_COARSE_LOCATION);
}
ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1);
txtLat = findViewById(R.id.latitudeTextview);
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
}
#Override
public void onLocationChanged(Location location) {
txtLat = findViewById(R.id.latitudeTextview);
String s = getString(R.string.latitude, location.getLatitude(), location.getLongitude());
txtLat.setText(s);
}
#Override
public void onProviderDisabled(String provider) {
Log.d("Latitude","disable");
}

Cast the view to TextView and make sure you are using correct view id
if i run this, for first time it will ask location permissions and gives the gps location but after closing and opening it again it wont give any data
have uninstall and re-install it agian, then it works fine, can anyone help me??

I have an activity in which I have a text view where I want to display the distance between the user's current location and a specific address. I have the Latitude and Logitude of the address but my issue is getting the user's location. My target is when the activity is created that's when I want to get his location' without pressing any button. I have tried multiple ways: getLastKnownLocation, onLocation changed etc, but the value returned is always null.
It's important to note that I am running the app on an emulator.
Sample code:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_business_list);
Bundle bundleUser = getIntent().getExtras();
final String owneruser = bundleUser.getString("username");
Bundle bundleType = getIntent().getExtras();
String type = bundleType.getString("type");
locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
final TextView t = (TextView) findViewById(R.id.textView2);
listener = new LocationListener() {
#Override
public void onLocationChanged(Location location) {
longitude = location.getLongitude();
latitude = location.getLatitude();
t.append("\n " + location.getLongitude() + " " + location.getLatitude());
}
#Override
public void onStatusChanged(String s, int i, Bundle bundle) {
}
#Override
public void onProviderEnabled(String s) {
}
#Override
public void onProviderDisabled(String s) {
Intent i = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(i);
}
};
final Location userLocation = new Location("");
userLocation.setLatitude(latitude);
userLocation.setLongitude(longitude);
}
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
switch (requestCode){
case 10:
update();
break;
default:
break;
}
}
void update(){
// first check for permissions
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestPermissions(new String[]{Manifest.permission.ACCESS_COARSE_LOCATION,Manifest.permission.ACCESS_FINE_LOCATION,Manifest.permission.INTERNET}
,10);
}
}
else {
locationManager.requestLocationUpdates("gps", 5000, 0, listener);
}
}
implement your activity to LocationListener :
public class MyActivity extends AppCompatActivity implements LocationListener {
private Location userLocation = new Location("");
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
}
#Override
public void onLocationChanged(Location location) {
if(location != null){
userLocation.setLatitude(location.getLatitude());
userLocation.setLongitude(location.getLongitude());
}
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
#Override
public void onProviderEnabled(String provider) {
}
#Override
public void onProviderDisabled(String provider) {
}
}
TRY this to grant permission:
if (ContextCompat.checkSelfPermission(context, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// Should we show an explanation?
if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION)) {
// Show an expanation to the user *asynchronously* -- don't block this thread waiting for the user's response! After the user sees the explanation, try again to request the permission.
} else {
// No explanation needed, we can request the permission.
ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, RC_ACCESS_FINE_LOCATION);
// MY_PERMISSIONS_REQUEST_READ_CONTACTS is an app-defined int constant. The callback method gets the result of the request.
}
}
and add this in your manifest:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
