First I am getting can't connect to local host , thus I added a few lines of code to propery of session like below to OAuth2Authenticator class , still authenicated successfully. But can't send out the mail.
首先，我无法连接到本地主机，因此我向 OAuth2Authenticator 类的会话属性添加了几行代码，但仍然成功通过身份验证。但是发不了邮件。
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "587");
I am using the same session object and SMTP transport objectwhich will be returned from OAuth2Authenticator class when I first authenticated successfully.
我正在使用相同的会话对象和 SMTP 传输对象，当我第一次成功进行身份验证时，它们将从 OAuth2Authenticator 类返回。
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress(msg.getFrom()));
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse(msg.getTo()));
message.setSubject(msg.getSubject());
message.setText(msg.getBody());
transport.send(message);

byte[] response = String.format("user=%sauth=Bearer %s",

Sorry people, answer is here: Javamail api in android using XOauthI tested, it works.
对不起的人，答案在这里：我测试过的使用 XOauth 的 android 中的 Javamail api，它有效。
"SMS style login" failure - Secure accounts with 2 step login (via phone SMS) reject sending email via SMTP (both RAW password & OAuth style, fail with a Authentication error). They will let you create the OAuth token but will not send email.
“短信式登录”失败 - 使用 2 步登录（通过电话短信）的安全帐户拒绝通过 SMTP 发送电子邮件（RAW 密码和 OAuth 样式，因身份验证错误而失败）。他们会让您创建 OAuth 令牌，但不会发送电子邮件。

You just need to authenticate. Follow this example, it also uses gmail: http://www.mkyong.com/java/javamail-api-sending-email-via-gmail-smtp-example/
您只需要进行身份验证。按照这个例子，它也使用 gmail：http: //www.mkyong.com/java/javamail-api-sending-email-via-gmail-smtp-example/

This is an old thread but it took me a very long time to figure this out after going through numerous forums (and none of them had the right answer) so I'll post it if it helps someone. Many of the answers above suggest using password which is incorrect
这是一个旧线程，但在浏览了许多论坛后，我花了很长时间才弄明白这一点（没有一个论坛给出正确答案），所以如果对某人有帮助，我会发布它。上面的许多答案都建议使用不正确的密码
If you are using the latest google apis with OAuth2 and also using the sample code @ http://code.google.com/p/google-mail-oauth2-tools/downloads/detail?name=oauth2-java-sample-20120904.zip&can=2&q=

Here are the steps to fix the problem
以下是解决问题的步骤
Run python oauth2.pyexactly as the instruction suggest in the zip download. The OAuth2Argument is the oauthtoken you must use in the code.
oauth2.py完全按照 zip 下载中的说明运行 python 。该OAuth2参数是你必须在代码中使用oauthtoken。
After running the OAuth2Authenticator.connectToSmtp("smtp.googlemail.com", 587, email, oauthToken, true)method to get the SMTPTransport. To send the message:
运行该OAuth2Authenticator.connectToSmtp("smtp.googlemail.com", 587, email, oauthToken, true)方法以获取SMTPTransport. 要发送消息：
//create the message
//Note that you do need to get the same session object that gets created within the connectToSmtp method.
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress("[email protected]"));
message.addRecipient(Message.RecipientType.TO, new InternetAddress("[email protected]"));
message.setSubject("This is the Subject Line!");
message.setText("This is actual message");
//this was the magic line that is needed - for authentication
transport.issueCommand("AUTH XOAUTH2 " + oauthToken, 235);
//send the message
transport.sendMessage(message, message.getAllRecipients());

I think so it is asking for authentication of your username.
我认为这是要求对您的用户名进行身份验证。
session=Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(fromUsername, password);
}
});
And then use above session in your code.
然后在您的代码中使用上面的会话。
I haven't use the code specified in the google link u mentioned but i use java mail api to send email from my gmail account.Use above code for authentication
我没有使用你提到的谷歌链接中指定的代码，但我使用 java mail api 从我的 gmail 帐户发送电子邮件。使用上面的代码进行身份验证
