我正在尝试使用通过Mandrill API和flat构建的Android应用发送电子邮件。而且我已经在Mandrill中注册了我的应用程序，并且从Mandrill网站上获得了API密钥，然后将其放入我的应用程序中，但是该应用程序崩溃了。
我的设备（仿真器）已经连接到互联网。
这是我的API密钥状态：
这是我的方法和代码
public void sendEmail(){
MandrillMessage allMessage = new MandrillMessage("545b0acfc446e44f6734be###########");
// create your message
EmailMessage message = new EmailMessage();
message.setFromEmail("info@mydocapp.net");
message.setFromName("buddy");
message.setHtml("<p>Your appointment added was successfully</p>");
message.setText("Your appointment date was fixed to 2018");
message.setSubject("Your appointment added was successfully");
// add recipients
Recipient recipient = new Recipient();
List<Recipient> recipients = new ArrayList<Recipient>();
recipient.setEmail("sahanpasindu07@gmail.com");
recipient.setName("Sahan");
recipients.add(recipient);
// add attachment if you want
// Attachment attachment = new Attachment();
// List<Attachment> attachments = new ArrayList<Attachment>();
//
// attachment.setType("image/png");
// attachment.setName("Image name");
// attachment.setContent(" set your base64 encode of your file");
// attachments.add(attachment);
message.setTo(recipients);
// message.setImages(attachments);
allMessage.setMessage(message);
allMessage.send();
}
我的logcat是

我知道有一些方法可以实现我的流程，但是我认为Mandrill比Java Mail API容易。但是在Java邮件api中，我注意到了一些错误，并且还需要对邮件设置进行一些更改，因此我选择了Mandrill。我愿意采取更好的方法。

此行告诉您问题的原因。
Caused by: java.lang.SecurityException: Permission denied (missing INTERNET permission?)
在您的清单顶部添加<uses-permission android:name="android.permission.INTERNET" />行。
