在android中導致異常的https文件下載

Question

我有一個servlet，我正在嘗試將文件寫入響應outputstream。

response.setContentType("application/octet-stream"); 
String value = "attachment;filename=\"" + appName + "\""; 
response.setHeader("Content-Disposition", value); 
response.setContentLength((int) file.length()); 
response.setBufferSize(99999); 
while ((length = fis.read(buffer)) > 0) { 
    sumBytes = sumBytes + length; 
os.write(buffer, 0, length); 
} 
os.flush(); 
fis.close(); 

這對HTTP工作正常，但是當我嘗試通過https下載相同的文件時出現SocketException。

我認爲在請求後https連接正在關閉。

Plase爲此提供解決方案。

這是例外。
