當我嘗試將文件附加到電子郵件時，出現java.io.FileNotFoundException：沒有內容提供者logcat輸出。 如果有人能告訴我我做錯了什麼，或者我應該做什麼，那就太好了。謝謝。什麼時候做 - java.io.FileNotFoundException：沒有內容提供者？
這是我如何將文件添加到電子郵件..：
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_STREAM, uri);
sendIntent.setType("video/3gp");
sendIntent.setType("video/mp4");
startActivity(sendIntent);
...這裏是整個logcat的錯誤輸出：

的事情是，當我嘗試使用 sendIntent.putExtra（Intent.EXTRA_STREAM，Uri.fromFile（新文件（URI）））; 它告訴我改變一個URI而不是一個字符串的URI，當我這樣做時，它告訴將Uri更改爲一個字符串......我不知道我該怎麼做。 – kivy 2010-07-20 10:31:55
如果沒有SD卡會怎麼樣？ – kadik 2016-03-16 09:56:41
@kadik然後該文件將不會被存儲在SD卡上，但該URI將仍然是相同的**形式** ...'file：// [分區] /路徑/到/文件 – SirDarius 2016-03-16 19:37:00
