는 다음의 XML 응답을받을 때하는 웹 서비스에 연결 2.3MB에 관한 서버에서 XML 응답을 수신 내가 OutOfMemoryError (I've referred this)하지만 찾을 수있는지고있어 간단한 방법입니다 내 방법은 여기OutOfMemoryError가은 : 2.3 MB

public synchronized String getUpdates(boolean news) throws Exception { 
     String response = null; 
     HttpPost httppost; 
     DefaultHttpClient httpclient; 
     ResponseHandler <String> res=new BasicResponseHandler(); 
     List<NameValuePair> nameValuePairs; 
     httppost = new HttpPost(context.getString(R.string.SYNCURL)); 
     HttpParams params = new BasicHttpParams(); 
     HttpProtocolParams.setContentCharset(params, "UTF-8"); 

     String lastupdate = null; 
     SharedPreferences preferences = context.getSharedPreferences(context.getPackageName(), Context.MODE_PRIVATE); 
     lastupdate = preferences.getString(LAST_UPDATE, DatabaseHelper.updateDate); 
     if(news) lastupdate = preferences.getString(LAST_UPDATE_NEWS, lastupdate); 

     httpclient = new DefaultHttpClient(params); 
     nameValuePairs = new ArrayList<NameValuePair>(2); 
     nameValuePairs.add(new BasicNameValuePair("reqDTTM", lastupdate)); 
     if(news)nameValuePairs.add(new BasicNameValuePair("doAction", "news")); 
     if(!preferences.getString(LAST_UPDATE, "").equalsIgnoreCase(DatabaseHelper.updateDate)) { 
      String timezon = UDFHelper.getTimeZon(context); 
      nameValuePairs.add(new BasicNameValuePair("tz", timezon)); 
     } 
     httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 
     response = httpclient.execute(httppost, res); 
     return response; 
}

가 String response에 큰 텍스트를 검색하는 문제가 발생 심하게 붙어 :

응답 = httpclient.execute (httppost, 고해상도);

응답을 String에 저장합니다. 그게 문제 야? 대체 솔루션은 무엇입니까? 여기

하지 실제로 문제가

HttpResponse r = httpclient.execute(httppost); 

HttpEntity entity = r.getEntity(); 

InputStream in = new ByteArrayInputStream(EntityUtils.toByteArray(entity)); 

File fl = new File(Environment.getDataDirectory().toString() + "/data/" + context.getPackageName() + "/" + FOLDER_NAME); 
if(!fl.exists()) fl.mkdir(); 

String PATH = Environment.getDataDirectory().toString() + "/data/" + context.getPackageName() + "/" + FOLDER_NAME + "/" + "update.xml"; 
FileOutputStream f = new FileOutputStream(PATH); 

byte[] buffer = new byte[1024]; 
int len1 = 0; 
while ((len1 = in.read(buffer)) > 0) { 
    f.write(buffer, 0, len1); 
} 
f.close();

을했다 : 그렇게하지 않습니다. 응답을 파일에 쓰거나 스트림을 파싱해야하지만 2.3 MB 문자열을 생성하지는 마십시오. 응답 뒤에 HttpEntity을 반환하는 응답 처리기를 작성한 다음 getContent 메서드를 사용하여 InputStream을 가져온 다음 파일에 저장 한 다음 파일을 처리하십시오.

제 대안 접근 방식 (다시 질문을 편집했습니다)을 다시보십시오. 튜토리얼이 있습니까? – Dharmendra

@Dharmendra EntityUtils.toByteArray (엔터티)를 호출하면 2.3MB 바이트 배열이 생성됩니다. 따라서 엔티티에서 배열을 가져 오려고하면 안됩니다. 그냥 스트림을 사용해보십시오. – kingori
