android - java.lang.IndexOutOfBoundsException: Invalid index 0, size is 0

Question

Here it's my code and logcat!!!!

public void onMapReady(GoogleMap googleMap) {

 mMap = googleMap;

 mMap.setOnMapClickListener(this);

 mMap.setMyLocationEnabled(true);

mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);

 mMap.setMyLocationEnabled(true);

mLocationRequest = new LocationRequest();

 mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

 mLocationRequest.setInterval(2000);

 mLocationRequest.setFastestInterval(1000);

LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

 String provider = locationManager.getBestProvider(new Criteria(), true);

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

        return;
    }
    Location location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
    if (location != null) {
        Log.e("TAG", "GPS is on");
        latitude = location.getLatitude();
        longitude = location.getLongitude();
        Toast.makeText(getApplicationContext()
                , "latitude:" + latitude + " longitude:" + longitude, Toast.LENGTH_SHORT).show();

    } else {

        locationManager.requestLocationUpdates(provider, 4000, 0,  this);
    }
    LatLng HYDERABAD = new LatLng(latitude, longitude);
    mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(HYDERABAD, 12));
    try {
        List<Address> addresses;
        Geocoder geocoder = new Geocoder(MapsActivity.this, Locale.ENGLISH);
        addresses = geocoder.getFromLocation(latitude, longitude, 1);

        if (Geocoder.isPresent()) {
            Toast.makeText(getApplicationContext(), "geocoder present",
                    Toast.LENGTH_SHORT).show();

          Address returnAddress = addresses.get(0);
           Log.d("LIne ", returnAddress.toString());
            String localityString = returnAddress.getAddressLine(2);
           Log.d("millatary ", localityString);

            str.append(localityString).append(" ");

            marker = new MarkerOptions().position(
                    new LatLng(latitude, longitude)).title(
                    str.toString());
            etOrigin.setText(str.toString());

            mCurrLocationMarker = mMap.addMarker(marker);
            Toast.makeText(getApplicationContext(), str,
                    Toast.LENGTH_SHORT).show();
        } else
            Toast.makeText(getApplicationContext(),
                    "geocoder not present", Toast.LENGTH_SHORT).show();

    } catch (IOException e) {
        Toast.makeText(getApplicationContext(), "Exception",
                Toast.LENGTH_SHORT).show();
    }

its my logcat and error showing here Address returnAddress = addresses.get(0);

From the documentation of Geocoder.getFromLocation)()

Returns

List a list of Address objects. Returns null or empty list if no matches were found or there is no backend service available.

In your example it's returning an empty List and you must check for this case:

if (addresses != null && !addresses.isEmpty()) {
    // Your code:
    Address returnAddress = addresses.get(0);
    Log.d("LIne ", returnAddress.toString());
    String localityString = returnAddress.getAddressLine(2);
    Log.d("millatary ", localityString);

    str.append(localityString).append(" ");

    marker = new MarkerOptions().position(
        new LatLng(latitude, longitude)).title(
                str.toString());
    etOrigin.setText(str.toString());

    mCurrLocationMarker = mMap.addMarker(marker);
    Toast.makeText(getApplicationContext(), str,
        Toast.LENGTH_SHORT).show();
}
