Android：java.net.SocketException的原因是什麼：連接超時？

Question

在我的應用程序中下載加載數據。每一件事情都很好，但有一些事情給出了很奇怪的反應，並拋出了socketException：connectiontimout？

請任何人告訴我這些異常的原因是什麼？所以我可以找出問題？

給我一些解決方案，以避免這些類型的異常

這裏記錄的那張............

Answer 1

「連接超時」是網絡環境中的預期行爲。在網絡連接可能不可靠的移動環境中，這一點甚至更令人期待。這意味着服務器無法響應一定的秒數。

因爲這是正常的行爲，你需要在你的android應用程序中處理它。嘗試重試，向用戶顯示錯誤消息，或者執行其他適當的操作。
