グーグルAPIから緯度を取得する方法と私はそれが完璧に機能するいくつかのコードを持っていますが、時々それは私たちに、私がインドにいるときでさえ英国の価値を与えています。

String surl = "http://mobilemaps.clients.google.com/glm/mmap";
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(surl);
httppost.setEntity(new MyCellIDRequestEntity(shortcid, lac));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
DataInputStream dis = new DataInputStream(entity.getContent());

// Read some prior data
dis.readShort();
dis.readByte();
// Read the error-code
int errorCode = dis.readInt();
System.err.println("Error Code iss::" + errorCode);
int api = myPrefs2.getInt("api", 0);
if (errorCode == 0) 
{
    lat = (double) dis.readInt() / 1000000D;
    lng = (double) dis.readInt() / 1000000D;
    System.err.println("lattitude::" + Double.toString(lng) + "::long::" + Double.toString(lat));
} else {
    // System.err.println("Wrong Error Code");
}
} catch (Exception e) {
}

これを試してみてください -

関数の呼び出し アクティビティから :

String location_name = getmylocation(latitude+","+longitude)

getMyLocation()メソッドは、現在地の文字列を提供します -

public String getmylocation(String value)
{           
      JSONObject json = JSONfunctions.getJSONfromURL("http://maps.googleapis.com/maps/api/geocode/json?latlng="+value+"&sensor=true");
      try{
        JSONArray  georesult = json.getJSONArray("results");
            JSONObject e = georesult.getJSONObject(0);

            String result = e.getString("address_components");
            JSONArray jArray1 = new JSONArray(result);
            JSONObject json_data=jArray1.getJSONObject(3);

            loc = json_data.getString("long_name");

      }catch(JSONException e)
      {
        e.printStackTrace();
      }    
    return loc;
}

を使用して場所を簡単に確認できます。String location_nameまた、必要な権限を追加することを忘れないでください -

ユーザーの場所の完全なアドレスを取得するのに役立つリンクを通過するだけです.
