I use the FigerPaint.java and ColorPickerDialog.java in a SampleProject "ApiDemos".
I added ability to save a screen image to a file "FigerPaint.java".
I use "ColorPickerDialog.java" without modification.
You can draw a picture on the screen,and save drawing to the gallery as PNG file.
If you are installing the Paint2SS, draw a picture on the screen shot.
Added support for screen rotation.
