推荐答案
是的,您可以看到示例
Yes sure you can see the example
public class MyService extends IntentService {
public MyService(String name) {
super("");
}
@Override
protected void onHandleIntent(Intent arg0) {
sendEmail();
}
public void sendEmail() {
try {
String host = "smtp.gmail.com";
String address = "biraj@gmail.com";
String from = "biraj@gmial.com";
String pass = "biraj123";
String to = "akash@gmail.com";
Multipart multiPart;
String finalString = "";
Properties props = System.getProperties();
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", host);
props.put("mail.smtp.user", address);
props.put("mail.smtp.password", pass);
props.put("mail.smtp.port", "587");
props.put("mail.smtp.auth", "true");
props.setProperty("mail.store.protocol", "imaps");
Log.i("Check", "done pops");
Session session = Session.getDefaultInstance(props, null);
Store store = session.getStore();
store.connect(host, address, pass);
DataHandler handler = new DataHandler(new ByteArrayDataSource(finalString.getBytes(), "text/plain"));
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
message.setDataHandler(handler);
Log.i("Check", "done sessions");
multiPart = new MimeMultipart();
InternetAddress toAddress;
toAddress = new InternetAddress(to);
message.addRecipient(Message.RecipientType.TO, toAddress);
Log.i("Check", "added recipient");
message.setSubject("Send Auto-Mail");
message.setContent(multiPart);
message.setText("Demo For Sending Mail in Android Automatically");
Log.i("check", "transport");
Transport transport = session.getTransport("smtp");
Log.i("check", "connecting");
transport.connect(host, address, pass);
Log.i("check", "wana send");
transport.sendMessage(message, message.getAllRecipients());
transport.close();
Log.i("check", "sent");
} catch (Exception e) {
e.printStackTrace();
}
}
}
注意:
无需制作单独的线程或异步任务.将要执行的代码直接放入onHandleIntent()
方法中.
No need to make separate thread or asynctask. Put the code directly that you want to execute in onHandleIntent()
method.
服务将在任务完成时自行停止.
Service will stop itself as task gets completed.
