Gmail中的附件使用代碼

Question

我有用於使用gmail帳戶發送電子郵件的工作代碼，現在我只想使用無需用戶交互的代碼進行附件。

Answer 1

public synchronized void sendMail(String subject, String body, String sender, String recipients, File attachment) throws Exception { 
    try{ 
    MimeMessage message = new MimeMessage(session); 
    message.setSender(new InternetAddress(sender)); 
    message.setSubject(subject); 

    MimeBodyPart mbp1 = new MimeBodyPart(); 
    mbp1.setText(body); 

    MimeBodyPart mbp2 = new MimeBodyPart(); 
    FileDataSource fds = new FileDataSource(attachment); 
    mbp2.setDataHandler(new DataHandler(fds)); 
    mbp2.setFileName(fds.getName()); 

    Multipart mp = new MimeMultipart(); 
    mp.addBodyPart(mbp1); 
    mp.addBodyPart(mbp2); 

    message.setContent(mp); 

    if (recipients.indexOf(',') > 0) 
     message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(recipients)); 
    else 
     message.setRecipient(Message.RecipientType.TO, new InternetAddress(recipients)); 
    Transport.send(message); 
    }catch(Exception e){ 

    } 
}

如果你想從SD卡發送一些文件，請使用這些代碼：

public static void email(Context context, String emailTo, String emailCC, 
    String subject, String emailText, List<String> filePaths) 
{ 
    //need to "send multiple" to get more than one attachment 
    final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND_MULTIPLE); 
    emailIntent.setType("text/plain"); 
    emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, 
     new String[]{emailTo}); 
    emailIntent.putExtra(android.content.Intent.EXTRA_CC, 
     new String[]{emailCC}); 
    //has to be an ArrayList 
    ArrayList<Uri> uris = new ArrayList<Uri>(); 
    //convert from paths to Android friendly Parcelable Uri's 
    for (String file : filePaths) 
    { 
     File fileIn = new File(file); 
     Uri u = Uri.fromFile(fileIn); 
     uris.add(u); 
    } 
    emailIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris); 
    context.startActivity(Intent.createChooser(emailIntent, "Send mail...")); 
}

我想你是不使用任何第三方庫發送郵件。

 Intent i = new Intent(Intent.ACTION_SEND); 
     i.setType("image/jpg"); 
     i.putExtra(Intent.EXTRA_EMAIL, new String[] {"someone@gmail.com"}); 
     i.putExtra(Intent.EXTRA_SUBJECT, "Subject"); 
     i.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///mnt/sdcard/myImage.gif")); 
     startActivity(i);
