Android 后台发邮件
Android 后台发邮件
基于sun公司的javamail,发送邮件：
1.下载三个jar：
依赖包
2.添加权限：
<
uses-permission
android:name
=
"android.permission.INTERNET"
/>
<
uses-permission
android:name
=
"android.permission.READ_EXTERNAL_STORAGE"
/>
<
uses-permission
android:name
=
"android.permission.WRITE_EXTERNAL_STORAGE"
/>
3.以下以qq邮箱为例,需要提前在qq邮箱设置里面开启smtp.在activity 调用：sendEMail();
