Android工作室邮件问题

Question

I have set up classes in my app to send a mail based on the user's name email and message.我在我的应用程序中设置了类，以根据用户名 email 和消息发送邮件。 It seems in app as if it's working fine but no actual email is being sent.在应用程序中似乎工作正常，但没有发送实际的 email。 Can Anybody help?有人可以帮忙吗？ Thank you in advance.先感谢您。

Here is the Gmail class i have set:这是我设置的 Gmail class ：

public class GMail {公共 class 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.");
}

} }

Here's my SendMailTask class这是我的 SendMailTask class

public class SendMailTask extends AsyncTask {公共 class 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();
}

} }

and here is the class that im trying to get the mail sent from:这是 class ，我试图从中获取邮件：

public class HelpPage extends AppCompatActivity {公共 class 帮助页面扩展 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();
                    }


                }

            });

}
