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