从Android应用程序发送邮件时出现“不太安全的应用程序”错误

Question

我使用Android Studio和这个库；https://github.com/yesidlazaro/GmailBackground .

我正在尝试从我的android应用程序发送电子邮件。但是每当我尝试从Gmail帐户发送电子邮件时，它都不起作用。因为谷歌将我的应用程序固定为“不太安全的应用程序”并阻止它。

我不得不从gmail的安全设置中允许不太安全的应用程序。但我不想这样做。我如何解决这个问题？使我的应用程序不成为不安全的应用程序？谢谢

创建SendMail。Java语言

 public class SendMail extends AsyncTask<Void,Void,Void> {
 private Context context;
 private Session session;

//Information to send email
private String email;
private String subject;
private String message;

private static int SPLASH_TIME_OUT = 3000;
//Send button


//Progressdialog to show while sending email
private ProgressDialog progressDialog;

//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 onPreExecute() {
    super.onPreExecute();
    //Showing progress dialog while sending email
    progressDialog = ProgressDialog.show(context,"Sending message","Please wait...",false,false);
}

@Override
protected void onPostExecute(Void aVoid) {
    super.onPostExecute(aVoid);
    //Dismissing the progress dialog
    progressDialog.dismiss();
    //Showing a success message
    Toast.makeText(context,"Message Sent",Toast.LENGTH_LONG).show();



}

@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("[e-mail]", "password");
                }
            });

    try {
        //Creating MimeMessage object
        MimeMessage mm = new MimeMessage(session);

        //Setting sender address
        mm.setFrom(new InternetAddress("[e-mail]"));
        //Adding receiver
        mm.addRecipient(Message.RecipientType.TO, new InternetAddress(email));
        //Adding subject
        mm.setSubject(subject);
        //Adding message
        mm.setText(message);

        //Sending email
        Transport.send(mm);

    } catch (MessagingException e) {
        e.printStackTrace();
    }
    return null;
}} 

然后在你的主要活动中。java：

    //Creating SendMail object
    SendMail sm = new SendMail(this, email_id, fullname, message);

    //Executing sendmail to send email
    sm.execute();
