我在這個問題上花了2周的時間。我寫了下面的代碼（Android和PHP）。它看起來好，但不工作或工作不正常。客戶端Android似乎發送了一些東西服務器端收到的東西，但我不知道它是什麼。Android：使用php腳本將圖像上傳到遠程MySql數據庫
下面的客戶端Android和服務器上的代碼。
謝謝。

總是很高興看到非練習五可讀的名字......這使得閱讀代碼變得如此美妙簡單易懂... – WarrenFaith 2013-02-13 10:44:10
爲什麼不把它轉儲到任何它正在獲取的位置，或者可能是SERVER變量下載到文件進行調試？ – 2013-02-13 11:32:54
我使用外部服務提供商。我怎樣才能做到這一點 ？ – 2013-02-13 12:36:15
