我已经在我的应用程序中设置了类，以根据用户的姓名、电子邮件和消息发送邮件。在应用程序中似乎工作正常，但没有发送实际的电子邮件。有人可以帮忙吗？预先感谢您。

这是我设置的 Gmail 类:

公共(public)类 GMail {

final String emailPort = "587"; // this is gMail's smtp port number
final String smtpAuth = "true";
final String starttls = "true";
final String emailHost = "smtp.gmail.com";
String fromEmail;
String fromPassword;
List<String> toEmailList;
String emailSubject;
String emailBody;
Properties emailProperties;
Session mailSession;
MimeMessage emailMessage;

// this will be the constructor of the email
public GMail(String fromEmail, String fromPassword, List<String> toEmailList, String emailSubject, String emailBody)
{
    this.fromEmail = fromEmail;
    this.fromPassword = fromPassword;
    this.toEmailList = toEmailList;
    this.emailBody = emailBody;

    //setting the server settings for Gmail
    emailProperties = System.getProperties();
    emailProperties.put("mail.smtp.port", emailPort);
    emailProperties.put("mail.smtp.auth", smtpAuth);
    emailProperties.put("mail.smtp.starttls.enable", starttls);
    Log.i("Gmail", "Mail server properties are now set.");

}

public MimeMessage createEmailMessage() throws AddressException,
        MessagingException, UnsupportedEncodingException{
        mailSession = Session.getDefaultInstance(emailProperties, null);
        emailMessage = new MimeMessage(mailSession);
        emailMessage.setFrom(new InternetAddress(fromEmail, fromEmail));//address setup
        for(String toEmail : toEmailList){
            Log.i("GMail", "toEmail" + toEmail);
            emailMessage.addRecipient(Message.RecipientType.TO,
                    new InternetAddress(toEmail));
        }
        emailMessage.setSubject(emailSubject); //email Subject
        emailMessage.setContent(emailBody, "text/html");
        return emailMessage;
}

public void sendEmail() throws AddressException, MessagingException
{
    Transport transport = mailSession.getTransport("smtp");
    transport.connect(emailHost, fromEmail, fromPassword);
    Log.i("Gmail", "allrecipients: " + emailMessage.getAllRecipients());
    transport.close();
    Log.i("Gmail", "Your Email has successfully been sent.");
}

}

这是我的 SendMailTask 类

公共(public)类 SendMailTask 扩展 AsyncTask {

private ProgressDialog statusDialog;
private Activity sendMailActivity;

public SendMailTask(Activity activity) {
    sendMailActivity = activity;
}

// make the method for showing dialog progress
protected void onPreExecute() {
    statusDialog = new ProgressDialog(sendMailActivity);
    statusDialog.setMessage("Setting up..");
    statusDialog.setIndeterminate(false);
    statusDialog.setCancelable(false);
    statusDialog.show();
}
//method for creation and sending of email
@Override
protected Object doInBackground(Object... args) {
    try{
        Log.i("SendMailTask", "Setting up your email ..");
        publishProgress("Processing all your information ..");
        GMail androidEmail = new GMail(args[0].toString(),
                args[1].toString(), (List) args[2], args[3].toString(),
                args[4].toString());
        publishProgress("Preparing your information ..");
        androidEmail.createEmailMessage();
        publishProgress("Sending your information ..");
        androidEmail.sendEmail();
        publishProgress("Information sent.");
        Log.i("SendMailTask", "Information sent.");

    }catch(Exception e){
        publishProgress(e.getMessage());
        Log.e("SendMailTask", e.getMessage(), e);
    }
    return null;
}
// creating method for dialog messages.
@Override
public void onProgressUpdate(Object... values){
    statusDialog.setMessage(values[0].toString());
}
//method to get rid of the dialog message.
@Override
public void onPostExecute(Object result){
    statusDialog.dismiss();
}

}

这是我试图获取发送邮件的类:

公共(public)类HelpPage扩展了AppCompatActivity{

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_help_page2);

    final EditText mail1 = findViewById(R.id.email1);
    final EditText mail2 = findViewById(R.id.email2);
    final EditText nameIn = findViewById(R.id.hName1);
    final Button btnSub = findViewById(R.id.helpBtn);
    final EditText msgIn = findViewById(R.id.hMsg);
    final String password = "xxxxxxxx";
    final String sendemail = "come2gopj@gmail.com";
    final String recemail = "c2grecieve@gmail.com";
    final boolean connt;

    ConnectivityManager connectivityManager = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
    if(connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE).getState() == NetworkInfo.State.CONNECTED ||
            connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI).getState() == NetworkInfo.State.CONNECTED){
        // Connection affirmative:)
        connt = true;
    }
    else {
        connt = false;
        Toast.makeText(getApplicationContext(), "You're not connected to the internet",
                Toast.LENGTH_LONG).show();
    }
    btnSub.setOnClickListener(
            arg0 -> {
                //method to make sure all fields are checked
                if(nameIn.getText().toString().equals("")||mail1.getText().toString().equals("")||mail2.getText().toString().equals("")||msgIn.getText().toString().equals(""))
                {
                    Toast.makeText(getApplicationContext(), "Please check you've filled all fields.",
                            Toast.LENGTH_LONG).show();
                }
                else if(connt!=true){
                    Toast.makeText(getApplicationContext(), "You're internet connection needs to be checked",
                            Toast.LENGTH_LONG).show();
                }
                else{
                    if(mail1.getText().toString().equals(mail2.getText().toString())){
                        Log.i("SendMailActivity", "Send Button Clicked.");
                        //declaring the recieving, password and sending of the email
                        List<String> toEmailList = Arrays.asList(recemail.split("\\s*,\\s*")); //Recipient List
                        Log.i("SendMailActivity", "To List: " + toEmailList);
                        String emailSubject = ((EditText) findViewById(R.id.hName1)).getText().toString();
                        String emailEmail = ((EditText) findViewById(R.id.email1)).getText().toString();
                        String emailBody = "User's Email : " + ((EditText) findViewById(R.id.email1)).getText().toString() + "\n" +
                                "User's message: "+((EditText) findViewById(R.id.hMsg)).getText().toString();
                        new SendMailTask(HelpPage.this).execute(sendemail, password,toEmailList,emailSubject,emailBody,emailEmail);//send the email with all the relevant data included
                        startActivity(new Intent(getApplicationContext(),AfterMail.class)); //this will start the next activity that i have included after the mail is sent
                    }
                    else{//method for checking the email inputs
                        Toast.makeText(getApplicationContext(), "Your emails don't match please try again.",
                                Toast.LENGTH_LONG).show();
                    }


                }

            });

}

这些是我按下发送按钮后在运行对话框中收到的消息:

I/SendMailActivity:单击发送按钮。I/SendMailActivity:到列表:[c2grecieve@gmail.com]

I/SendMailTask:设置您的电子邮件..

I/Gmail:邮件服务器属性现已设置。
