一定のチャンク化されたJSON応答を受信する必要がある状況があります。応答を受信するたびに、JSONを解析して、操作の現在のステータスでUIを更新する必要があります。

各応答を個別に受信し、応答の受信が完了するまで情報をUIにポストバックする簡単な方法を見つけることができません。

誰かがこれに光を当てることができれば、私は感謝するでしょう！

http呼び出しを行う101の異なる方法があります。応答を読み取るための正しい方法を備えた正しい方法が必要です。

-編集-これに追加するだけです。私が抱えている問題は、JSONデータを読み取っていないことです。各データチャンクを個別に取得し、各チャンク間でUIにポストバックしています–NathofGod27秒前編集

        DefaultHttpClient http_client = new DefaultHttpClient();
        HttpGet httpGet = new HttpGet(url);
        HttpResponse response = http_client.execute(httpGet);

        StatusLine statusLine = response.getStatusLine();
        int statusCode = statusLine.getStatusCode();
        HttpEntity entity = response.getEntity();

        InputStream in = entity.getContent();
        StringBuffer out = new StringBuffer();
        byte[] b = new byte[4096];
        int n =  in.read(b);
        out.append(new String(b, 0, n));        
        String resultdata = out.toString();
