Android Geocoder bazı cihazlarda farklı davranır

Android'de Geocoder gerçekten tüm cihazlarda aynı davranışı yok edilir. Ben aşağıdaki cihazlarla Geocoder test ettik:

• Samsung (Android 4.4 ve 5.1)
• Lenovo (Android 5.0)
• Vivo (Android 6.0.1)
• Andromax (Android 5.1.1)
• Xiaomi (Android 5.1)

Tüm cihazlar listesini dönen ama Xiaomi, sıfır listeleri döndürür. Yani, biz geocoder bağlı olamaz. Solüsyon kullanarak kendi Geocoder uygulaması yaratmaktır Google Geocoding API ve liste 0 döndürür zaman kullanabilirsiniz.

İşte Geocoder kullanmak gibi exatly kullanılabilir (SO onu buldum, ama kaynağını hatırlayamıyorum) geocoder uygulanması:

    String address = String.format(Locale.US,
        "https://maps.googleapis.com/maps/api/geocode/json?latlng=%1$f,%2$f&sensor=false&language="
            + Locale.getDefault().getCountry(), lat, lng);

      JSONObject jsonObject = new JSONObject(responseStr);

      retList = new ArrayList<Address>();

      if ("OK".equalsIgnoreCase(jsonObject.getString("status"))) {
        JSONArray results = jsonObject.getJSONArray("results");
        if (results.length() > 0) {
          for (int i = 0; i < results.length() && i < maxResult; i++) {
            JSONObject result = results.getJSONObject(i);
            Address addr = new Address(Locale.getDefault());

            JSONArray components = result.getJSONArray("address_components");
            String streetNumber = "";
            String route = "";

                  addr.setLocality(component.getString("long_name"));
                } else if (type.equals("street_number")) {

                } else if (type.equals("route")) {
                  route = component.getString("long_name");
                }
              }
            }
            addr.setAddressLine(0, route + " " + streetNumber);

            addr.setLatitude(
                result.getJSONObject("geometry").getJSONObject("location").getDouble("lat"));
            addr.setLongitude(
                result.getJSONObject("geometry").getJSONObject("location").getDouble("lng"));
            retList.add(addr);
          }
        }
      }
    } catch (IOException e) {
      Log.e(TAG, "Error calling Google geocode webservice.", e);
    } catch (JSONException e) {
      Log.e(TAG, "Error parsing Google geocode webservice response.", e);
    }

    return retList;
  }
}

Unutmayın Android Geocoder API olmadı günlük kota.
