Android通過Intent發送電子郵件含附件（另附） 如何在Android系統中發送帶附件的電子郵件呢? 其實通過Intent可以很方便的發送Email，只需要短短10行代碼就可以處理，這裏Android開發網就以在sdcard上的 android123.cwj文件爲例，通過Intent來發送電子郵件。完整代碼如下

File file = new File("\sdcard\android123.cwj"); //附件文件地址

Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra("subject", file.getName()); //
intent.putExtra("body", "android123 - email sender"); //正文
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file)); //添加附件，附件爲file對象
            if (file.getName().endsWith(".gz")) {
                intent.setType("application/x-gzip"); //如果是gz使用gzip的mime
            } else if (file.getName().endsWith(".txt")) {
                intent.setType("text/plain"); //純文本則用text/plain的mime
            } else {
                intent.setType("application/octet-stream"); //其他的均使用流當做二進制數據來發送
            }
  startActivity(intent); //調用系統的mail客戶端進行發送
