最近几天做好了应用【
贱泰迪】,其中有个意见反馈,发送邮件,
我知道可以调用系统发送邮件,但这种方法有个弊端,就是您的手机必须安装Mail的客户端,
因此我想不用系统发送邮件这种方式,能不能向任意邮箱发送邮件呢?给我自己丢下了一个命题。
于是我调查,发现SMTP发送email 无需系统支持,无需配置,
经过多次尝试,多次失败,终于完成了此项功能。
先来看应用【
贱泰迪】的效果,
填写您的邮箱、密码等,我就能收到您的反馈意见,是不是很方便呢,
更多的效果,您可以下载贱泰迪(
http://down.mumayi.com/464309)查看。
此贴,讲这个功能给扣出来了,并附上其他的两种方法发送邮件。
效果图如下:
1、使用Mail客户端发送邮件
这种方法前提您的手机必须安装Mail客户端,您可以测试的时候下载QQ邮箱客户端,看看运行的效果。
- case R.id.button1:
- // 创建Intent
- Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
- // 设置内容类型
- emailIntent.setType(“plain/text”);
- // 设置额外信息
- emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,
- new String[] { “收件人邮箱” });// 比如qq邮箱,测试的时候可以手机安装qq邮箱客户端
- emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, “主题”);
- emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, “内容”);
- // 启动Activity
- startActivity(Intent.createChooser(emailIntent, “发送邮件…”));
- break;
复制代码
2、使用SMTP发送邮件
这是此贴的重点所在,SMTP的全称是“Simple Mail Transfer Protocol”,即简单邮件传输协议。
它是一组用于从源地址到目的地址传输邮件的规范,通过它来控制邮件的中转方式。
SMTP 协议属于 TCP/IP 协议簇,它帮助每台计算机在发送或中转信件时找到下一个目的地。
SMTP 服务器就是遵循 SMTP 协议的发送邮件服务器。
它需要三个jar包,下载地址:
https://code.google.com/p/javamail-android/downloads/list
下载后复制libs,即可。
下面介绍两种方法实现使用SMTP发送邮件
(1)方法一
- case R.id.button2:
- new Thread() {
- @Override
- public void run() {
- EmailSender sender = new EmailSender();
- // 设置服务器地址和端口,网上搜的到
- sender.setProperties(“smtp.qq.com”, “465”);
- // 分别设置发件人,邮件标题和文本内容
- try {
- sender.setMessage(“发件人邮箱”, “主题主题1”, “内容内容1”);
- sender.setReceiver(new String[] { “收件人邮箱” });
- sender.sendEmail(“smtp.qq.com”, “发件人邮箱”, “发件人邮箱密码”);
- } catch (AddressException e) {
- e.printStackTrace();
- Log.e(“wxl”, “AddressException”, e);
- } catch (MessagingException e) {
- e.printStackTrace();
- Log.e(“wxl”, “MessagingException”, e);
- }
- }
- }.start();
- break;
复制代码

- break;
复制代码

- }
- @Override
- protected void onProgressUpdate(Integer… progress) {
- // 这个函数在doInBackground调用publishProgress时触发,虽然调用时只有一个参数
- // 但是这里取到的是一个数组,所以要用progesss[0]来取值
- // 第n个参数就用progress[n]来取值
- super.onProgressUpdate(progress);
- }
- @Override
- protected void onPostExecute(String result) {
- // doInBackground返回时触发,换句话说,就是doInBackground执行完后触发
- // 这里的result就是上面doInBackground执行后的返回值,所以这里是”执行完毕”
- // setTitle(result);
- if (“ok”.equals(result)) {
- Toast.makeText(getApplicationContext(), “发送成功”,
- Toast.LENGTH_SHORT).show();
- } else {
- Toast.makeText(getApplicationContext(), “发送失败”,
- Toast.LENGTH_SHORT).show();
- }
- super.onPostExecute(result);

代码粘完了,这里采用了线程和异步,对于新手可以学学。【贱泰迪】采用的是第二种方法。
下面开始说一下注意点:
首先加上联网的权限,<uses-permission android:name=”android.permission.INTERNET” />,这是小问题
以上代码完成没有问题,但是运行会抛这样的异常:
这是为什么,使用SMTP来发送E-mail,因此您的邮箱必须开启此项服务,
【QQ邮箱】【设置】【账户】【POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV服务】如下图:
