Вы должны использовать GMailSender для этого
добавить это к деятельности, где вы хотите отправить почту
Я использую подписку, поэтому я положил ее в AlertDialog
@OnClick({R.id.btn_newsLetter_ok, R.id.btn_newsLetter_cancel})
public void onClick(View view) {
switch (view.getId()) {
case R.id.btn_newsLetter_ok:
email = etNewsLetterEmail.getText().toString().trim();
if (email.isEmpty()|| !android.util.Patterns.EMAIL_ADDRESS.matcher(email).matches()) {
Toast.makeText(context, "please enter a valid email address!!", Toast.LENGTH_SHORT).show();
}
else if(NetworkManager.isNetworkAvailable(context)){
try {
mailBody = mailBody.replace("@email",email);
sender = new GMailSender("yourEmail@gmail.com", "yourPassword");
StrictMode.setThreadPolicy(policy);
new MyAsyncClass().execute();
} catch (Exception ex) {
Toast.makeText(context, ex.toString(), Toast.LENGTH_SHORT).show();
}
dismiss();
}
break;
case R.id.btn_newsLetter_cancel:
dismiss();
break;
}
}
public class MyAsyncClass extends AsyncTask<Void, Void, Void> {
ProgressDialog pDialog;
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(context);
pDialog.setMessage("Please wait...");
pDialog.show();
}
@Override
protected Void doInBackground(Void... mApi) {
try {
// Add subject, Body, your mail Id, and receiver mail Id.
sender.sendMail("hi kevin", mailBody, "from@gmail.com", "to@gmail.com");
}
catch (Exception ex) {
}
return null;
}
@Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
pDialog.cancel();
Toast.makeText(context, "Email send", Toast.LENGTH_SHORT).show();
}
}
создайте Java-файл с именем GMailSender и вставьте
public class GMailSender extends javax.mail.Authenticator {
private String mailhost = "smtp.gmail.com";
private String user;
private String password;
private Session session;
static {
Security.addProvider(new JSSEProvider());
}
public GMailSender(final String user, final String password) {
this.user = user;
this.password = password;
Properties props = new Properties();
props.setProperty("mail.transport.protocol", "smtp");
props.setProperty("mail.host", mailhost);
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.class",
"javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");
props.put("mail.smtp.starttls.enable", "true");
props.setProperty("mail.smtp.quitwait", "false");
session = Session.getInstance(props, new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(user, password);
}
});
session = Session.getDefaultInstance(props, this);
}
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(user, password);
}
public synchronized void sendMail(String subject, String body,
String sender, String recipients) throws Exception {
MimeMessage message = new MimeMessage(session);
DataHandler handler = new DataHandler(new ByteArrayDataSource(
body.getBytes(), "text/plain"));
message.setSender(new InternetAddress(sender));
message.setSubject(subject);
message.setDataHandler(handler);
if (recipients.indexOf(',') > 0)
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse(recipients));
else
message.setRecipient(Message.RecipientType.TO, new InternetAddress(
recipients));
Transport.send(message);
}
public class ByteArrayDataSource implements DataSource {
private byte[] data;
private String type;
public ByteArrayDataSource(byte[] data, String type) {
super();
this.data = data;
this.type = type;
}
public ByteArrayDataSource(byte[] data) {
super();
this.data = data;
}
public void setType(String type) {
this.type = type;
}
public String getContentType() {
if (type == null)
return "application/octet-stream";
else
return type;
}
public InputStream getInputStream() throws IOException {
return new ByteArrayInputStream(data);
}
public String getName() {
return "ByteArrayDataSource";
}
public OutputStream getOutputStream() throws IOException {
throw new IOException("Not Supported");
}
}
}
создайте другой класс с именем JESSEProvider и вставьте его
public class JSSEProvider extends Provider {
public JSSEProvider() {
super("HarmonyJSSE", 1.0, "Harmony JSSE Provider");
AccessController
.doPrivileged(new java.security.PrivilegedAction<Void>() {
public Void run() {
put("SSLContext.TLS","org.apache.harmony.xnet.provider.jsse.SSLContextImpl");
put("Alg.Alias.SSLContext.TLSv1", "TLS");
put("KeyManagerFactory.X509","org.apache.harmony.xnet.provider.jsse.KeyManagerFactoryImpl");
put("TrustManagerFactory.X509","org.apache.harmony.xnet.provider.jsse.TrustManagerFactoryImpl");
return null;
}
});
}
}
если я что-то забыл, скажи мне.
