Android 服务在推送通知发送时启动并在服务任务完成后停止

Question

我想在我通过 parse.com 发送推送通知时启动服务，并且当服务任务（后台工作）完成时我停止服务。 编辑：在我发送邮件的服务中

 try {
                sender = new GMailSender("id",
                        "password");

                sender.sendMail(
                        "subject",
                        "This is Body", "sender mail id",
                        "recei. id");


            } catch (Exception e) {
                Log.e("SendMail", e.getMessage(), e);
            }

Gmail 发件人类别

  public class GMailSender extends javax.mail.Authenticator{
  //public class GMailSender extends javax.mail.Authenticator {   
private String mailhost ="smtp.gmail.com";

    Security.addProvider(new com.provider.JSSEProvider());

    this.user = user;   
    this.password = password;   

    Properties props = new Properties();   
    props.setProperty("mail.transport.protocol", "smtp");   
    props.setProperty("mail.host", mailhost);

            "javax.net.ssl.SSLSocketFactory");   
    props.put("mail.smtp.socketFactory.fallback", "false");   
    props.setProperty("mail.smtp.quitwait", "false");   

    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 {   
    try{
    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);   
    }catch(Exception e){

    }
    Transport.send(message);
}   

    public void addAttachment(String filename) throws Exception { 
        BodyPart messageBodyPart = new MimeBodyPart(); 
        DataSource source = new FileDataSource(filename); 
        messageBodyPart.setDataHandler(new DataHandler(source)); 
        messageBodyPart.setFileName(filename); 

        multipart.addBodyPart(messageBodyPart); 
        message.setContent(multipart);
        System.out.println("u r in add attachment"+multipart);
      } 

// } // 公共类 ByteArrayDataSource 实现 DataSource {
私有字节[] 数据；
私有字符串类型；

    public ByteArrayDataSource(byte[] data, String type) {   
        super();   
        this.data = data;   
        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");   
    }   
}   

}

Jsse 类

    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;
        }
    });
}

}

是的，你可以看到例子

    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：

无需创建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。

服务将在任务完成后自行停止。
