android - 在 Android 中发送电子邮件

Question

我正在尝试通过单击按钮发送电子邮件，发送邮件是用户给定的识别码。但是电子邮件发送不正确。谁能帮我解决这个问题。

我根据这个创建了我的应用程序:-

Sending Email in Android using JavaMail API without using the default/built-in app

这是我收到的 logcat 消息。

我用这个方法，

Intent intent = new Intent(Intent.ACTION_SEND);
    intent.setType("message/rfc822");

    String possibleEmail = new String();
    mailArray = new String[]{getString(R.string.mail), possibleEmail};

    Pattern emailPattern = Patterns.EMAIL_ADDRESS;
    Account[] accounts = AccountManager.get(getBaseContext()).getAccounts();

    for (Account account : accounts) {
        if (emailPattern.matcher(account.name).matches()) {
            possibleEmail = account.name;
        }
    }

    if(sendToMeCheckBox.isChecked()){

        mailArray [1] = possibleEmail;
    }

    intent.putExtra(Intent.EXTRA_EMAIL, mailArray );
    intent.putExtra(Intent.EXTRA_SUBJECT, "Some random subject");
    intent.putExtra(Intent.EXTRA_TEXT, "Some random text");

    try {
        startActivity(Intent.createChooser(intent, "Send email..."));
    } catch (Exception e) {
        Toast.makeText(this, "There are no mail applications on the device!", Toast.LENGTH_LONG).show();
    }
}
