This is my coding below, it is giving me an output but its not my exact location. (Its giving me some location in USA). I implemented a facility to get the user's current location using the Fused Location Provider API. and also i created intent service to fetch address from latitude and longitude using Geocoder. Please help me out with this issue for my project. Here is my coding below:
This is my main Activity
public class ContactDetails extends AppCompatActivity {
private static final int REQUEST_CODE_LOCATION_PERMISSION = 1;
public TextView LatLong;
ProgressBar pb;
private ResultReceiver resultReceiver;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_contact_details);
resultReceiver=new AddressResultReceiver(new Handler());
LatLong = (TextView) findViewById(R.id.latlong);
pb = (ProgressBar) findViewById(R.id.progressBar);
findViewById(R.id.buttonGetCurrentLocation).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (ContextCompat.checkSelfPermission(
getApplicationContext(), Manifest.permission.ACCESS_FINE_LOCATION
) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(
ContactDetails.this,
new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
REQUEST_CODE_LOCATION_PERMISSION
);
} else {
getCurrentLocation();
}
}
});
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == REQUEST_CODE_LOCATION_PERMISSION && grantResults.length > 0) {
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
getCurrentLocation();
} else {
Toast.makeText(this, "Permission Denied!", Toast.LENGTH_SHORT).show();
}
}
}
private void getCurrentLocation() {
pb.setVisibility(View.VISIBLE);
final LocationRequest locationRequest = new LocationRequest();
locationRequest.setInterval(10000);
locationRequest.setFastestInterval(3000);
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// ActivityCompat#requestPermissions
// here to request the missing permissions, and then overriding
// public void onRequestPermissionsResult(int requestCode, String[] permissions,
// int[] grantResults)
// to handle the case where the user grants the permission. See the documentation
// for ActivityCompat#requestPermissions for more details.
// return;
}
