To take a screenshot of the Android Emulator, click the Take screenshot button.
In the Screen Capture dialog that appears, you can recapture, edit, or copy
the captured image. Once you're satisfied with the image, click Save. The
emulator creates a PNG file with the name
Screenshot_yyyymmdd-hhmmss.png, using the year, month,
day, hour, minute, and second of the capture. You can change the name, if you prefer, and
choose where to save the file.
You can also take screenshots from the command line with either of the following commands:
screenrecord screenshot [destination-directory]
adb emu screenrecord screenshot [destination-directory]
