PDF Viewing for Android
PDF Viewing is now available directly in Google Drive. For environments where this cannot be deployed, Google PDF Viewer offers the same capabilities in a standalone app. View, print, search and copy text from pdf documents while you’re on the go.
Note 1: PDF Viewer is primarily meant for use in the context of the Android for Work Program (android.com/work).
Note 2: No icon is available in launcher, the app is launched when opening a pdf (from Downloads or another app).
