我在這些行上得到192行錯誤。

BufferedOutputStream out = new BufferedOutputStream(new FileOutputStream(fileData)); 
BufferedInputStream in = new BufferedInputStream(urlConn.getInputStream(), 8192); 

如何解決問題。

Answer 1

urlConn.setReadTimeout（10000）;

您將讀取超時設置爲10秒。

java.net.SocketTimeoutException：讀超時

超時讀取。

您的超時時間太短，或者不是太短，並且您在設置超時時檢測到您嘗試檢測到的情況。
