Android \ Intent：發送帶有圖片附件的電子郵件

Question

收件人正在收到電子郵件，但沒有附件。下面是代碼，哪位高手知道爲什麼我有什麼錯？

Intent messageIntent = new Intent(android.content.Intent.ACTION_SEND); 

String aEmailList[] = { "mymailgmail.com" }; 
messageIntent.putExtra(android.content.Intent.EXTRA_EMAIL, aEmailList); 

messageIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject); 
...  
messageIntent.setType("image/jpeg"); 
File downloadedPic = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS), "MyApp.jpg"); 

messageIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(downloadedPic)); 

startActivity(Intent.createChooser(messageIntent, getResources().getString(R.string.chooser_pic))); 

我得到：

文件：//附件路徑必須指向文件：// SD卡。忽略附件文件：//...file name is MyApp.jpg

我沒有收到圖片，只在文本消息之上。謝謝。

試試下面的代碼...

Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND); 
emailIntent.setType("application/image"); 
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{strEmail}); 
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,"Test Subject"); 
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "From My App"); 
emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///mnt/sdcard/Myimage.jpeg")); 
startActivity(Intent.createChooser(emailIntent, "Send mail...")); 

Answer 2

Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND); 
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, emailaddress); 
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, message); 
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject); 
emailIntent.setType("application/image"); 

Uri uri = Uri.parse("file://" + filepath); 
emailIntent.putExtra(Intent.EXTRA_STREAM, uri); 
startActivity(emailIntent);
