【中文标题】Android 服务在推送通知发送时启动并在服务任务完成后停止【英文标题】：Android Service start when push notification send and stop after service task complete 【发布时间】：2014-05-13 05:26:26 【问题描述】：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

"password");

"subject",

【问题讨论】：
你的服务在做什么？ 我将我的问题添加到包含我的整个代码的以下链接中：***.com/questions/23602926/… 使用 IntentService 而不是服务。 IntentService 将创建单独的线程并执行给定的任务并在任务完成时自行停止 如果您给出任何 IntentService 示例以及我在哪里调用了哪个方法 【参考方案1】：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。
【讨论】：
做了以上修改后，其实我发现我的发送邮件有问题，我把发送邮件的代码分开，知道邮件发送有问题，我用发送邮件代码编辑我的问题以上，请帮助查找一次发送两次邮件的问题。 Weldon，它为我工作的朋友，非常感谢你加标记:)以上是关于Android 服务在推送通知发送时启动并在服务任务完成后停止的主要内容，如果未能解决你的问题，请参考以下文章
