如何在安卓中打开gmail

Question

我只是想通过我的应用程序打开 Gmail 应用程序，并想从我的应用程序设置电子邮件、主题和消息。

我尝试过 GmailService，但它不支持密件抄送或抄送电子邮件。链接：https ://github.com/yesidlazaro/GmailBackground

BackgroundMail.newBuilder(this)

    .withUsername("[e-mail]")

    .withPassword("password12345")

    .withMailto("[e-mail]")

    .withType(BackgroundMail.TYPE_PLAIN)

    .withSubject("this is the subject")

    .withBody("this is the body")

    .withOnSuccessCallback(new BackgroundMail.OnSuccessCallback() {

        @Override

        public void onSuccess() {

            //do some magic

        }

    }).withOnFailCallback(new BackgroundMail.OnFailCallback() {

        @Override

        public void onFail() {

            //do some magic

        }

    }).send();

我想将密件抄送和抄送功能与附件、主题和消息一起使用。
