Google Drive SDK Update announced at the Google I/O comes with a number of updates including an expanded API, a simplified developer experience and mobile app support.

"The new Drive API exposes all standard file operations as well as methods to list and search files, convert between formats, copy files, manage revisions, and share files with users. The API is based on open standards, including a RESTful service architecture, JSON data exchange format, and OAuth2 for authorization. And with a simplified design and drop-in client libraries available in eight languages, using the API has never been easier," explains Google.

Also, Google today, announced full mobile support for Android and iOS apps using the Drive SDK.

"Mobile apps can securely use the Drive API to read and write files directly to Google Drive. Users can also "Open with" on mobile devices to view or edit content from their phone or tablet just like they do on the web. (Installation of apps via the Chrome Web Store is no longer required.)," posted Mike Procopio is a Software Engineer for Google Drive.

Also, the company introduced today several new features for Drive apps for the web including sharing to your apps with the familiar Drive sharing box. "With just a few lines of JavaScript added to your app, users can share their files with the new embeddable sharing component," Google said.

Also, users can now open Google document formats in any app that supports one of the many export formats available. For example, an app that faxes PDFs can now fax a Google document, spreadsheet, or presentation directly.

Finally, some new Drive apps include: mobile photo editors for cropping photos on a phone to a web-based IDE for slingin' code in the cloud will soon join the apps already available today.

Google also announced today enhancements to Google Apps Script to help build richer applications and share apps with users.

"You can now create scripts from or from Google Drive. Plus, your projects are now stored in Google Drive, and you can share them just like a Google document or spreadsheet," Google informs.

HtmlService launched today allows you to create web apps using HTML, client-side JavaScript, CSS and Apps Script. You can also use jQuery to build web apps. HtmlService uses Google Caja to ensure that the HTML content served by your web apps is safer for you and your users.

And, "ScriptDb," brings a better way to store application's data.

"Every script now has an embedded JSON database. You no longer have to rely on a spreadsheet to store the data. Using ScriptDb, you can store a larger volume of data and search easily," Google said.

You can learn more about ScriptDb on the Google Apps Script Developers page.

Also, your apps can now, with authorization, run as the user behind the keyboard, not just the script owner. This brings a new level of versatility to web apps built with Apps Script.

Finally, Google also made it easier to distribute apps. "You can now publish your apps in the Chrome Web Store. Register and package your app directly from the Publish menu in Google Apps Script. Then customize your listing from the Chrome Web Store and publish your app to the world," Google adds.

Google also posted an updated developer reference documentation, and also created a new user guide for Apps Script.

Google App Engine platform version 1.7.0 released at the I/O, now let developers serve their applications via HTTPS on custom domains. "We're offering both SNI and VIP based SSL, which provide both a low cost and universally supported option, respectively," Google said.

If you are interested in signing up for a Premier Account to get access to our European cluster, as well as Premium Support and invoice billing, please contact our sales team at," Google said.
