尝试使用Android版JavaMail时应用程序崩溃,android,android-asynctask,jakarta-mail,Android,Android Asynctask,Jakarta Mail,我试图在我的应用程序中使用JavaMail Android端口，但当我尝试发送任何内容时，我的应用程序崩溃。我按照指南创建了Mail类。然后在我的main活动中添加了 protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Mail m = new Mail("mailt

我试图在我的应用程序中使用JavaMail Android端口，但当我尝试发送任何内容时，我的应用程序崩溃。我按照指南创建了

Mail

类。然后在我的

main活动中

添加了

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Mail m = new Mail("mailtosendfrom", "mypassword");
    new SendMailTask().execute(m);
}

private class SendMailTask extends AsyncTask<Mail, Void, Void> {
    @Override
    protected Void doInBackground(Mail... mail) {
        Mail m = mail[0];

        String[] toArr = {"mailtosendto"};
        m.setTo(toArr);
        m.setFrom("mailtosendfrom");
        m.setSubject("This is an email sent using my Mail JavaMail wrapper from an Android device.");
        m.setBody("Email body.");
        try {
            m.send();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }
}

创建时受保护的void（Bundle savedInstanceState）{
super.onCreate（savedInstanceState）；
setContentView（R.layout.activity_main）；
Mail m=新邮件（“mailtosendfrom”、“mypassword”）；
新建SendMailTask（）.execute（m）；
}
私有类SendMailTask扩展了AsyncTask{
@凌驾
受保护的Void doInBackground（邮件…邮件）{
邮件m=邮件[0]；
字符串[]toArr={“mailtosendto”}；
m、 设置为（toArr）；
m、 setFrom（“mailtosendfrom”）；
m、 setSubject（“这是一封使用my Mail JavaMail包装器从Android设备发送的电子邮件。”）；
m、 setBody（“电子邮件正文”）；
试一试{
m、 send（）；
}捕获（例外e）{
e、 printStackTrace（）；
}
返回null；
}
}

我之前对异步任务有一个问题。希望有帮助
 代码不是问题，模拟器是
我只是在一台设备上而不是在模拟器上尝试了这一点，它工作得完美无缺。
你在清单文件中给出了“”吗？发布整个错误。你能把完整的日志放进去吗？@Oskar崩溃异常在哪里？它看起来像04-19 18:13:42.200 3730-3746/com.oskar.ratingapp E/
。现在添加了一个E
。我删除了logcat中只针对我的应用程序的过滤器。
