User input on mobile devices
User input is handled very differently on mobile devices.
PocketPC
A PocketPC has a pointing device but no cursor. So for
this reason the rollover event is meaningless when creating
buttons, you only need to consider the default image and the
image to use if the button is pressed. Just as with a desktop
machine you can have Input text boxes and embedded fonts.
Mobile phones
Mobile phones have generally less screen space, no pointing
device and no such thing as an Input text box. Flash Lite for
i-mode, DoCoMo mobile phones, uses three keys for navigation:
Up, Down and Select. The Left and Right keys are
reserved for the i-mode browser. These three keys correspond
to the Shift+Tab, Tab, and Enter keys on the desktop
versions of the Flash Player. The keys 0,1,2,3,4,5,6,7,8,9,*,
and # are also available. These correspond to the same keys
on the desktop versions of the Flash Player.

Ten top tips for migrating content from
desktop to mobile
Not all content that you have created for a desktop will port to a mobile device but there are some
golden rules to follow when creating artwork:

2 Convert bitmaps to the correct colour depth for the device.
3 Don’t use gradients.
4 Don’t use alpha transparency.
5 Avoid full screen redraws, such as occur when fading up a scene or doing a full screen
tween.
6 Set the quality to medium.
7 Use ‘Modify/Shape/Optimize...’ to reduce the number of curves in a scene to the
minimum.
8 Don’t have an outline around a fill unless absolutely necessary.
9 Simplify detail where possible.
10 Use a thick line instead of a fill if possible.
You should also limit the number of simultaneous tweens. Don’t tween symbols that have alpha
levels that are not fully opaque (less than 100 per cent). Avoid large masks, extensive motion, alpha
