從Google API Geocode獲取正確的重音 - Android

Question

我使用http://maps.google.com/maps/api/geocode從某些座標獲取並解決問題。

當我在APP JSON響應，有加重的任何字符出來一個「錯誤」 ---> O = A 3

我的APP是UTF-8

這裏編碼是獲取代碼的部分是一個從API

JSONArray results = jsonObject.getJSONArray("results"); 

JSONObject r = results.getJSONObject(0); 
JSONArray addressComponentsArray = r.getJSONArray("address_components"); 

JSONObject addressComponents = addressComponentsArray.getJSONObject(0); 
numero = addressComponents.getString("short_name"); 
Log.i("Número", numero); 

JSONObject addressComponents1 = addressComponentsArray.getJSONObject(1); 
rua = addressComponents1.getString("long_name"); 
Log.i("Rua", rua); 

而這裏的信息是全班

class EncontrarEndereco extends AsyncTask<String, String, JSONObject> { 

     ProgressDialog pDialog = new ProgressDialog(GPSActivity.this); 

     @Override 
     protected void onPreExecute(){

      pDialog.show(); 
     }

Answer 1

這裏有什麼解決我的問題，該位處理的InputStream

char[] buffer = new char[2048]; 
Reader reader = new InputStreamReader(entity.getContent(), "UTF-8"); 
StringBuilder stringBuilder = new StringBuilder(); 

while (true) { 
    int n = reader.read(buffer); 
    if (n < 0) { 
     break; 
    } 
    stringBuilder.append(buffer, 0, n); 
} 

這是整個代碼中。
