android選擇圖片或拍照圖片上傳到服務器(包括上傳參數) （轉）

 

最近要搞一個項目，須要上傳相冊和拍照的圖片，不負所望，終於完成了！  不過須要說明一下，其實網上不少教程拍照的圖片，都是縮略圖不是很清晰，因此須要在調用照相機的時候，事先生成一個地址，用於標識拍照的圖片URI

具體上傳代碼：

1.選擇圖片和上傳界面，包括上傳完成和異常的回調監聽

注意：通常是下面兩種狀況：
一、若是攝像的時候手動傳入一個URI，則onActivityResult不會返回URI。
二、若是攝像的時候沒有傳入一個URI，則onActivityResult會返回URI，而後查詢獲得文件名。
 
還有極少數比較特別的狀況，但都是一些定製系統的問題。 
 
解析Intent的Data要用ContentProvider去查系統數據庫，獲得文件路徑，進而獲得文件名。轉自：　http://blog.csdn.net/blueangle17/article/details/9613807
