问题:

I'm new to using SQLite on Android and I have some error here.

I have this app:

http://imgur.com/gallery/The7Q

With the code below I can click on the save button and on the first item on the list, in this case London, then go to the location of the place.

But When I add a second place and try to to the above I get a:

java.lang.IndexOutOfBoundsException: Index: 1, Size: 1

On this line:

 //Centralize the selected item
        Orientation selectedLocation = geocodingResult.getResults().get(getIntent().getIntExtra(SELECTED_POSITION, 1)).getGeometry().getLocation();

How to I solve this?

Map Activity:

public class MapActivity extends AppCompatActivity {

private GoogleMap map;
private GeocodeResult geocodingResult;

List<Address> listAddresses;

String address = "";

public LatLng latlng;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps);

    map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.activity_map_googlemap)).getMap();

    addMarkers();
}

 // Show the markers on the map
public void addMarkers() {
    Geocoder geocoder = new Geocoder(getApplicationContext(), Locale.getDefault());
    geocodingResult = getIntent().getParcelableExtra(MainActivity.RESULT);

    if (geocodingResult != null) {
        //  For each Geocoding object, get the results markers
        for (Geocoding geocoding : geocodingResult.getResults()) {
            map.addMarker(new MarkerOptions()
                    .position(new LatLng(geocoding.getGeometry().getLocation().getLat(), geocoding.getGeometry().getLocation().getLng()))
                    .icon(BitmapDescriptorFactory.defaultMarker())
                    .title(geocoding.getFormattedAddress()) //location name that will be shown when click the marker
                    .snippet(String.valueOf(geocoding.getGeometry().getLocation().getLat())
                            + ", "
                            + String.valueOf(geocoding.getGeometry().getLocation().getLng())) //coordinates that will be shown when click the marker
            );
            try {
                latlng = new LatLng(geocoding.getGeometry().getLocation().getLat(), geocoding.getGeometry().getLocation().getLng());
                listAddresses = geocoder.getFromLocation(geocoding.getGeometry().getLocation().getLat(), geocoding.getGeometry().getLocation().getLng(), 1); // Here 1 represent max location result to returned, by documents it recommended 1 to 5
            } catch (IOException e) {
                e.printStackTrace();
            }
            Log.d("LIST", String.valueOf(listAddresses));
        }


        //Centralize the selected item
        Orientation selectedLocation = geocodingResult.getResults().get(getIntent().getIntExtra(SELECTED_POSITION, 1)).getGeometry().getLocation();
        map.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(selectedLocation.getLat(), selectedLocation.getLng()), 4));
    }

Your error occurs when the coding can't reach the specific index. You may check on this thread.

IndexOutOfBound exception means you've got a problem because you're trying to access an index which doesn't exist or is empty (not null). For example if you've got an array with only two elements, so it only has index 0 and 1, and you try to access index 2 you'll get an IndexOutOfBoundException because index 2 doesn't exist. If you make an array of 10 elements and only fill 5, indexes 4-9 will be empty, accessing those might cause an IndexOutOfBoundException.

Here's a possible workaround on how to fix this:

If you're using an IDE it might help you to debug the problem by removing the throws statements. Throws statements "pass the buck" when it comes to exceptions, you're not actually handling exceptions by using throws. Try-catch statements handle exceptions much better because they narrow down the area where the problem is (because they 'test' the code within the try brackets.

Throws have their place, but for debugging try-catch can be much more helpful.
