问题 http://developer.android.com/training/printing/index.html documentation tells how to print a custom content by rendering it on a PDF canvas and sending thus created PDF document for printing.

问题 I have an app that needs to be full screen most of the time. I know that if an alert is shown or other window is displayed, over the top of the activity window, full screen is temporarily removed.
