needs to send mail, how can invoke that intent
答
您可以不要直接使用JavaMail API的版本，黑客发送一封电子邮件，但你可以很容易地让用户发送一个你使用Intent.ACTION_SEND为和意图选配。
You can't send an email directly without using a hacked version of the javamail apis, but you can easily have the user send one for you using Intent.ACTION_SEND and an Intent Chooser.
final Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.setType("text/plain");
emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[]{"webmaster@website.com"});
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "my subject");
emailIntent.putExtra(Intent.EXTRA_TEXT, "body text");
context.startActivity(Intent.createChooser(emailIntent, "Send mail..."));
请确保你是在实际设备上，当你测试这个code，因为它不会在模拟器中工作。
Make sure you're on an actual device when you test this code as it won't work from within the emulator.
