Based on sample script from Demo Mode for the Android System UI, with a few tweaks to make it work as expected.

Added screen grabbing option if save path is specified.

e.g.
./android-screenshooting-demo-mode.sh on 1400 .

will apply the demo mode options and save a screenshot on the current path.

reminder: make sure the script is executable (chmod +x android-screenshooting-demo-mode.sh
