Areas of mobile design1. Mobile web or mobile app?
2. Does size really matter?
3. Human Interaction - what?
4. Wireframing/prototyping
5. Choices, choices..
Mobile web, or app?

From Hard Boiled Web Design, by Andy Clarke
Example for iPhone
.myImage { height: 40px; width: 100px; -webkit-background-size: 100px 40px; background: url("images/myImage.jpg");}
@media screen and (-webkit-device-pixel-ratio: 2) { .myImage { background: url("images/[email protected]"); }}
Flex media queries ActionBar { chromeColor: #000000; }
@media (os-platform: "Android"){ ActionBar { chromeColor: #999999; /* dark gray */ }}@media (os-platform: "IOS"){ ActionBar { chromeColor: #6DA482; /* blue */ }}
This example code uses the default ActionBarSkin skin class from the Mobile theme and changes thechromeColor property. You can use this same technique to completely replace the default skin with your own platform-specific skin.
Choices using themes
• Create your own build scripts
• Manually change the arguments per platform
• Refactor your project into multiple projects that share the same base project and/or libraries
Design for..• latency
• segment your content (provide your own app structure and navigation
• pixel denisty and screen size
• use true full screen for video
• reinforce spation relationships with motion
If you are going to bother making a web app, consider the experience
Decide things like,
How is the user going to navigate?
SizeDoes it matter?
Pixel Density/Screen sizeTo get the ppi, you first need to find out how many pixels there are diagonally.
This is the square root of each side squared, added together (from a2 + b2 = c2)
Android densities: low, medium, high and extra highDensity-independent pixel (dp)A virtual pixel unit that you should use when defining UI layout, to express layout dimensions or position in a density-independent way.
The density-independent pixel is equivalent to one physical pixel on a 160 dpi screen, which is the baseline density assumed by the system for a "medium" density screen. At runtime, the system transparently handles any scaling of the dp units, as necessary, based on the actual density of the screen in use. The conversion of dp units to screen pixels is simple: px = dp * (dpi / 160). For example, on a 240 dpi screen, 1 dp equals 1.5 physical pixels. You should always use dp units when defining your application's UI, to ensure proper display of your UI on screens with different densities.http://developer.android.com/guide/practices/screens_support.html
So much for easyResolutionThe total number of physical pixels on a screen.
• Screen densityThe quantity of pixels within a physical area of the screen, usually referred to as DPI (dots per inch).
• Density-independent pixel (DP)This is a virtual pixel unit that you would use when defining a layout’s UI in order to express the layout’s dimensions or position in a density-independent way. The density-independent pixel is equivalent to one physical pixel on a 160 DPI screen, which is the baseline density assumed by the system of a “medium”-density screen. At runtime, the system transparently handles any scaling of the DP units as necessary, based on the actual density of the screen in use. The conversion of DP units to screen pixels is simple: pixels = DP * (DPI / 160). For example, on a 240 DPI screen, 1 DP equals 1.5 physical pixels. Always use DP units when defining your application’s UI to ensure that the UI displays properly on screens with different densities.
Device Screen res (height x width)
iPhone - 320 x 480iPhone 4 - 320 x 480 (scaled up by a factor of 2)
Nokia N97 - 360 x 640
HTC Legend - 320 x 480
LG eXpo - 480 x 800
Apple Human Interface Guidelines recommends a
hit target no less than 44 X 44px
Pixel Screen Densities. Bad above, and good below
From Apple’s guidelines
Fingers, where to go
Gestures
by Steven Hoober
Human Interactioin Guidelines
Be aware of orientation
Add detail and depth
Typography is just as important
Think twice before you designa standard control!
Create a great brand experience
Think top down
Where is their hand going to be?
Make usage easy and logical
Design using physicality and realism
Always work at a higher resolutionthan you need.
Where to gohttp://developer.android.com/guide/practices/screens_support.html

Wireframing/prototyping
Fireworks Android template
Vector or Raster?
Vector is fine for simple shapes
If it is complex... rasterize it!
Think in terms of render times

Using Fireworks Pages/Master Pages
Why I use FireworksCanvas size
Vectors vs bitmaps
Layers, sublayers
Master pages
States and sharing to layers
slices
9-alice scaling guides
symbols
orientation and resizing
Choices and more choices!Flex 4.5.x (design view has improved!)
Fireworks: Great for wireframing, is a vector web graphics too, has 9-slice scaling, master pages, great export options, symbols, drag and drop to Flash for continued functionality. States, click throughs, and more.
Photoshop: pixel-level control
Illustrator: Visuals, Flash integration, SVG
After Effects: High-fidelity prototyping, transitions
Flash Pro: Interactive design, High-fidelity prototypes, AIR applications, export for mobile, works great with Flash Builder
Flash Catalyst: Great for wireframing, prototyping click-through and transitions
