Last week, Google released the desktop version of Gmail online app's support for office document preview, and today they released the mobile version of Google Docs's support for office document preview, now users of Android, iPhone, and iPad can see the document preview interface that is more suitable for mobile devices. Supported document formats include PowerPoint, PDF, and word (unfortunately, Excel tables are not supported ).
The preview of these documents is based on the original format, including the title, footer, and tail note. You can even use dual-finger scaling on devices that support multi-touch.
Currently, Google Docs's mobile device preview function only allows you to directly access Google Docs using a browser. If you are in Gmail of mobile edition, you cannot directly use Google Docs of mobile edition to open the file attachment in the email.
