Tjenesten er ikke tilgjengelig mens du ringer geoCoder.getFromLocation ()

API vil kaste en "tjenesten er ikke tilgjengelig exception" dersom en slik tjeneste ikke er tilgjengelig på enheten. Bruk metode isPresent()for å sjekke for eksistensen av tjenesten.

bruke dette trikset.

bare redigere project.properties

# Project target
target=Google Inc.:Google APIs:16

Årsaken er at Geocoder klassen er til stede i kjernen Android rammeverket, men er avhengig av kode bidratt med Google API-er for å fungere skikkelig. Selv om AVD inkluderer Google-API, trenger fortsatt prosjektet skal bygges mot det spesifikke bygge målet.

Løsning ved hjelp av direkte tilgang til google maps:

    public static LatLng getLocationFromString(String address)
        throws JSONException {

    HttpGet httpGet = new HttpGet(
            "http://maps.google.com/maps/api/geocode/json?address="
                    + URLEncoder.encode(address, "UTF-8") + "&ka&sensor=false");
    HttpClient client = new DefaultHttpClient();
    HttpResponse response;
    StringBuilder stringBuilder = new StringBuilder();

    try {
        response = client.execute(httpGet);
        HttpEntity entity = response.getEntity();
        InputStream stream = entity.getContent();
        int b;
        while ((b = stream.read()) != -1) {
            stringBuilder.append((char) b);
        }
    } catch (ClientProtocolException e) {
    } catch (IOException e) {
    }

    JSONObject jsonObject = new JSONObject(stringBuilder.toString());

    double lng = ((JSONArray) jsonObject.get("results")).getJSONObject(0)
            .getJSONObject("geometry").getJSONObject("location")
            .getDouble("lng");

    double lat = ((JSONArray) jsonObject.get("results")).getJSONObject(0)
            .getJSONObject("geometry").getJSONObject("location")
            .getDouble("lat");

    return new LatLng(lat, lng);
}

    public static List<Address> getStringFromLocation(double lat, double lng)
        throws ClientProtocolException, IOException, JSONException {

    String address = String
            .format(Locale.ENGLISH,                                 "http://maps.googleapis.com/maps/api/geocode/json?latlng=%1$f,%2$f&sensor=true&language="
                            + Locale.getDefault().getCountry(), lat, lng);
    HttpGet httpGet = new HttpGet(address);
    HttpClient client = new DefaultHttpClient();
    HttpResponse response;
    StringBuilder stringBuilder = new StringBuilder();

    List<Address> retList = null;

    response = client.execute(httpGet);
    HttpEntity entity = response.getEntity();
    InputStream stream = entity.getContent();
    int b;
    while ((b = stream.read()) != -1) {
        stringBuilder.append((char) b);
    }

    JSONObject jsonObject = new JSONObject(stringBuilder.toString());

    retList = new ArrayList<Address>();

    if ("OK".equalsIgnoreCase(jsonObject.getString("status"))) {
        JSONArray results = jsonObject.getJSONArray("results");
        for (int i = 0; i < results.length(); i++) {
            JSONObject result = results.getJSONObject(i);
            String indiStr = result.getString("formatted_address");
            Address addr = new Address(Locale.getDefault());
            addr.setAddressLine(0, indiStr);
            retList.add(addr);
        }
    }

    return retList;
}

Jeg hadde samme geocoder feil, men ingen av de ovennevnte brukt. Det ville ikke kjøre en av mine Android-enheter. Så husket jeg at jeg hadde accedently drept noen kjører service. Løsningen ble å ta ut batteriet i noen sekunder og re-installere den. Og det fungerte uten å endre koden :))

Noen enheter har ikke support for Geocoder, så hva du trenger å gjøre er å lage din egen geocoder.

Innerst inne må opprette en asynkron oppgave å be google for adressen og behandle json respons.

Bruke aquery, jeg gjør noe som dette:

public void asyncJson(String address){
        address = address.replace(" ", "+");

        String url = "http://maps.googleapis.com/maps/api/geocode/json?address="+ address +"&sensor=true";

        aq.ajax(url, JSONObject.class, new AjaxCallback<JSONObject>() {

                @Override
                public void callback(String url, JSONObject json, AjaxStatus status) {                        

                        if(json != null){

                                 //here you work with the response json
                                 JSONArray results = json.getJSONArray("results");                               
                                Toast.makeText(context, results.getJSONObject(1).getString("formatted_address"));

                        }else{                                
                                //ajax error, show error code
                                Toast.makeText(aq.getContext(), "Error:" + status.getCode(), Toast.LENGTH_LONG).show();
                        }
                }
        });        
}

Jeg hadde den samme feilen, legge under tillatelser for å løse det.

Den beste løsning på dette problemet er å bruke det samme som Google Geocoder klasse hvis den opprinnelige Geocoder mislykkes

addresses = geocoder.getFromLocation(...);
if (addresses == null || addresses.isEmpty())

Starte enheten på nytt, og det vil fikse problemet.

Dette fungerte utmerket for meg fordi når Geocoder ikke fungerer, jeg bruker direkte tilgang til Google Maps.

Jubel!

For følgende linje

Geocoder gCoder = new Geocoder(context, Locale.getDefault());

Bruk Contextav aktivitets og ikke brukgetApplicationContext()

Jeg har også hatt problemer med denne feilen. Det skjedde da jeg oppdaterte min enhet til Marshmallow nylig.

Hvis jeg starte på nytt, fungerer det en gang, men da vil mislykkes, og ikke i det hele tatt etterpå.

Jeg opprettet en AsyncTask som andre mennesker, som bare returnerer adresse fra det første resultatet av JSON respons.

For å bruke koden under, kaller det konstruert med api-tasten, og du bruker en plassering objekt som input for å utføre AsyncTask. Du kan importere Sted med følgende. import android.location.Location;Du må få det gjeldende steds med LocationManager, ved å be om en oppdatering til den.

    new ReverseGeoCodeTask(GOOGLE_API_KEY).execute(location);

Pass på at du erstatter API-nøkkel med din egen, og også sørge for at du aktiverer den i Google Cloud konsollen. Det er der du administrere alle Google-API for ditt prosjekt.

Kopier denne klassen som en indre klasse i aktivitet som du trenger det motsatte geokodes adresse.

Hadde det samme problemet på Android 6 . Problemet var i Apptillatelser . Selv om kartene fungerer må du la "Get posisjon" tillatelse i app tillatelser.

Den beste fall er alltid å sjekke denne tillatelsen tillatt når du forventer å få plass i resultatet.

Jeg bruker denne metoden for å få full adresse fra sted:

public Address getFullAddress(Place place){
    Address address;

    Locale aLocale = new Locale.Builder().setLanguage("en").build();
    Geocoder geocoder = new Geocoder(this, aLocale);

    try {
        List<Address> addresses = geocoder.getFromLocation(place.getLatLng().latitude,place.getLatLng().longitude, 1);

        address = addresses.get(0);

        return address;

    } catch (IOException e) {
        e.printStackTrace();
    }

    return null;
}
