apache.http.MalformedChunkCodingException: Chunked stream ended unexpectedly

產生的緣由，應該是服務器返回的數據不是規範的格式 。
我使用的xutils的httpUtils來實現網絡通訊的，關於讀取數據是在

StringDownloadHandler類中源代碼

 inputStream = entity.getContent();
 BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, charset));
 String line = "";
 while ((line = reader.readLine()) != null) {
     sb.append(line).append('\n');
     current += OtherUtils.sizeOfString(line, charset);
     if (callBackHandler != null) {
         if (!callBackHandler.updateProgress(total, current, false)) {
             break;
         }
     }
 }
這樣的實現，並不夠健壯。

使用二進制的讀取更加穩健

inputStream = entity.getContent();

byte data[] = new byte[40000];
long totalContactsCount = -1;
int readContactsCount = 0;
int currentByteReadCount = 0;
while ((currentByteReadCount = inputStream.read(data)) != -1) {
    String readData = new String(data, 0, currentByteReadCount);
    sb.append(readData);
    // then +1 progress on every ...},{... (JSON object separator)
    if (readData.indexOf("}~{") >= 0) {
        readContactsCount++;
    }

   /* // publishing the progress....
    if (totalContactsCount > 0) {
        publishProgress((int)(readContactsCount * 100 / totalContactsCount));

    }*/

}
