Android编程-发送邮件
我在Android中使用以下代码发送邮件:Android编程-发送邮件,android,email,mms,Android,Email,Mms,我在Android中使用以下代码发送邮件: Intent emailIntent = new Intent(Intent.ACTION_SEND); emailIntent.setType("text/html"); emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,sendTo ); emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "test" );
Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.setType("text/html");
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,sendTo );
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "test" );
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "msg" );
在编译和运行代码时,它会询问我选择“GMail”、“BlueTooth”等应用程序的选项,但我希望邮件在没有用户干预的情况下发送。即使通过彩信发送,对我来说也会更好。有人能建议我怎么做吗?您需要在项目中包含java邮件库和依赖项,然后编写一个类似下面的帮助器类
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(String user, 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.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 {
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");
}
}
}
JSSEProvider类

发送电子邮件就这么简单了
Gmail发件人=新的Gmail发件人(“用户名”、“密码”);
发件人。sendMail(“主题”,正文,“发件人”,收件人);
没有用户干预,您无法使用内置应用发送电子邮件或短信。你必须像其他回答提到的那样使用外部邮件库。Android已经有了“GMail”应用程序。我怎样才能使用同一个帐户发送邮件,而不是提醒用户提供这些详细信息?我想你不能:要么你询问用户的密码,要么你让gmail应用程序为你发送邮件。假设用户的凭据存储在gmail应用程序中,如果他们被公开,你可能可以通过内容提供商检索他们。否则,您必须要求提供凭据或使用您为应用程序设置的gmail帐户发送邮件。我使用上面的类来报告未捕获的异常。这个“JSSEProvider”来自哪里?我在“security”包中找不到它……这是抽象提供者类的具体实现,我在上面编辑了这篇文章,以显示有效的实现。很抱歉对你的评论回复太晚了,我已经有一段时间没上这个网站了
