70. Android Picture-in-Picture Mode
When multi-tasking in Android was covered in earlier chapters, Picture-in-picture (PiP) mode was mentioned briefly but not covered in any detail. Intended primarily for video playback, PiP mode allows an activity screen to be reduced in size and positioned at any location on the screen. While in this state, the activity continues to run and the window remains visible regardless of any other activities running on the device. This allows the user to, for example, continue watching video playback while performing tasks such as checking email or working on a spreadsheet.
This chapter will provide an overview of Picture-in-Picture mode before Picture-in-Picture support is added to the VideoPlayer project in the next chapter.
