Use fused Location Provider to get the current location
I have this activity and want to get the current location but now don’t know how to do it the right way: Also What is REQUEST_CODE_ASK_PERMISSIONS?
Do I have to generate one?
public class MainActivity extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener {
private double longitude;
private double latitude;
private TextView latitudeText, longitudeText;
private FusedLocationProviderClient fusedLocationProviderClient;
private GoogleApiClient googleApiClient;
private LocationManager locationManager;
private LocationListener locationListener;
private LocationRequest locationRequest;
private LocationCallback locationCallback;
final private int REQUEST_CODE_ASK_PERMISSIONS = 123;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
latitudeText = findViewById(R.id.latitudeText);
longitudeText = findViewById(R.id.longitudeText);
getLocation();
}
private void getLocation() {
locationRequest = new LocationRequest()
.setInterval(2000).setFastestInterval(2000).setPriority(1000);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(locationRequest);
SettingsClient client = LocationServices.getSettingsClient(this);
Task<LocationSettingsResponse> task = client.checkLocationSettings(builder.build());
locationCallback = new LocationCallback() {
@Override
public void onLocationResult(LocationResult locationResult) {
for (Location location : locationResult.getLocations()) {
latitude = location.getLatitude();
longitude = location.getLongitude();
latitudeText.setText(String.valueOf(latitude));
longitudeText.setText(String.valueOf(longitude));
}
}
};
task.addOnSuccessListener(this, new OnSuccessListener<LocationSettingsResponse>() {
@Override
public void onSuccess(LocationSettingsResponse locationSettingsResponse) {
}
});
}
@Override
protected void onResume() {
super.onResume();
if (ContextCompat.checkSelfPermission(this,Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(MainActivity.this,new String[]{Manifest
.permission. ACCESS_FINE_LOCATION},REQUEST_CODE_ASK_PERMISSIONS);
} else if(){
}
}
@Override
public void onConnected(@Nullable Bundle bundle) {
}
@Override
public void onConnectionSuspended(int i) {
}
@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
}
}

Solution
Add dependencies in build.gradle(Module:app).
implementation 'com.google.android.gms:play-services-location:16.0.0'
Declare the necessary permissions in the list
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
