Google PDF Viewer
PDF files can now be opened directly in Google Drive.
For environments where this is not available, Google PDF Viewer offers the same functionality in a standalone app. This allows you to view, print and search for and copy PDF documents on the go.
First note: PDF Viewer is primarily intended for use with the Android for Work program (http://android.com/work).
Second note: No icon is available in the launcher. The app launches when a PDF from the downloads or other app is opened.
