Java 不幸的是，我的程序在单击“发送邮件”按钮时停止。我已经添加了三个jar文件和对internet的许可

一段时间以来，我一直在尝试使用android的java mail api发送电子邮件。我在互联网上尝试了几个代码，但当apk在移动设备上运行时，仍然会收到相同的错误消息，上面写着“appName不幸停止”。我是android新手，如果有人能在这个平台上帮助我，我会非常高兴。我也使用android studio作为我的IDE。谢谢你
下面是我的XML的代码

SendMail类：

        private ProgressDialog progressDialog;

        @Override
        protected void onPreExecute() {
            super.onPreExecute();

                Message message = new MimeMessage(session);
                message.setFrom(new InternetAddress("busben97@gmail.com"));

                Transport.send(message);

            } catch(Exception e) {
                Toast.makeText(MainActivity.this,e.toString(),Toast.LENGTH_LONG).show();
            }
            return null;
        }
    }
