所以我想制作一个按钮发送邮件，就像申请注册一样。用户通过编辑文本向我发送他的电子邮件，并且电子邮件将从他的邮件发送到指定的电子邮件，例如“example@gmail.com”。该应用程序没有错误，但它没有发送任何电子邮件。
我已经拥有JSSEProvider，GMailsender和互联网许可。

}
}

}
});
}
}
如果有人能提供帮助我会感激不尽。

它为我工作....发送电子邮件的最简单方法。
像这样呼叫SendMail.class
SendMail sm = new SendMail(context, "receiver@gmail.com", "Emergency Alert", email_message);
sm.execute();
<强> SendMail.class
public class SendMail extends AsyncTask<Void,Void,Void> {
//Declaring Variables
private Context context;
private Session session;
//Information to send email
private String email;
private String subject;
private String message;
//Class Constructor
public SendMail(Context context,String email,String subject,String message){
//Initializing variables
this.context = context;
this.email = email;
this.subject = subject;
this.message = message;
}
@Override
protected Void doInBackground(Void... params) {
//Creating properties
Properties props = new Properties();
//Configuring properties for gmail
//If you are not using gmail you may need to change the values
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");
//Creating a new session
session = Session.getDefaultInstance(props,
new javax.mail.Authenticator() {
//Authenticating the password
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("sender@gmail.com", "example@2018");
}
});
try {
//Creating MimeMessage object
MimeMessage mm = new MimeMessage(session);
//Setting sender address
mm.setFrom(new InternetAddress(email));
//Adding receiver
mm.addRecipient(Message.RecipientType.TO, new InternetAddress(email));
//Adding subject
mm.setSubject(subject);
//Adding messageZZ
mm.setText(message);
//Sending email
Transport.send(mm);
} catch (MessagingException e) {
e.printStackTrace();
}
return null;
}
}
还在jar文件夹
lib个文件
