电子邮件程序不能访问你的应用程序的私有文件，在这种情况下，你要发送的数据库。将数据库复制到文件夹在SD卡，并从那里将其安装。

                              }


        } 

解决方案

The email program can't access your application's private files, in this case, the database you are trying to send. Copy the database to a folder in the SD card and attach it from there.
