First, if you need to use the softkeys, you have to write down the code as below to enable it.
fscommand2(“SetSoftKeys”, “Left”, “Right”);

Then we need a KeyLinstener:Object to access the button event and define the behavior.

var keyListener:Object = new Object();
keyListener.onKeyUp = function() {
if (Key.getCode() == ExtendedKey.SOFT1) {
//Left Softkey
} else if (Key.getCode() == ExtendedKey.SOFT2) {
//Right Softky
} else if (Key.getCode() == Key.LEFT) {
} else if (Key.getCode() == Key.RIGHT) {
} else if (Key.getCode() == Key.UP) {
} else if (Key.getCode() == Key.DOWN) {
} else if (Key.getCode() == Key.ENTER) {
}
};
Key.addListener(keyListener);

If you would like to define the numeric keys(0-9), you need to use the Key.getAscii() start from 48 to 57.
use 43 to define the “*”
use 35 to define the “#”

[ Notice ] Don’t use getCode() for numeric keys, because the keyCode of 3=# and 8=*.

Reference: Get Key Code(Execute in your mobile phone or emulator in Flash 8

For the mobile phone, getURL( ) has more functions.

1. make a call: getURL(“tel:0800080080″);
2. send short message: getURL(“sms:0943434454″);
3. send multimedia message: getURL(“mms:0943434454″);

If you would like to know more, you can refer to the official document.
Flash Lite 1.x ActionScript Language Reference.pdf (p20-22)

If you use Macromedia Flash MX 2004 to create your Flash Lite content, you need a Flash Lite Bundler to let Flash Lite recognize the formats like MIDI, 3gp..supported by your device.

[ Sound Support ]
MIDI: Device dependent/Device dependent
PCM and ADPCM: Support/Support
MP3: Support/Support

[ Image & Video Support ]
PNG: During authoring/During authoring or device dependent
JPG: Support/Support
GIF: During authoring/During authoring or device dependent
Animation GIF: During authoring/During authoring
MPG-4 and other video formats: Not support/Device dependent

Three ways to optimizing graphics and animations
1. Simplifing animation
When you use tween shape, try to covert to the keyframes and remove the tween settings.

2.Use bmps in place of vectors
It will increase the memory if you use the vectors. So try to use bmp as possible.
Flash Lite [8] Bmp v.s. Vector

3.Adjusting the render quality
Use fscommand2(“SetQuality”, “low/high”) to adjust the render quality.
But you can’t test this function via emulation, you need to test it on your device.

1. Out of Memory
2. Stack Limit Reached
3. Currupted SWF
4. ActionScript Stuck
5. ActionScript Processing
6. ActionScript Infinity Loop
7. Invalid Frame Buffer
8. Invalid Display Rect
9. Invalid Frame Number
10. Invalid Key
11. Bad JPEG Data
12. Bad Sound Data
13. Root Movie Unloaded

You can get more details from this document Developing Flash Lite Applications(p.75-76). It will appears in the output window, but you can’t see these informations in your device until Macromedia update the Flash Lite Player.

1. Out of memory
2. Stack limit reached
3. Corrupt SWF data
4. ActionScript stuck
5. Infinite AS loop
6. Bad JPEG data
7. Bad sound data
8. Cannot find host
9. ActionScript error
10. URL too long

But there is a problem, because it won’t focus on the input text field directly. User need to press UP/DOWN to set it focus, as below right state. If the text field as left, it won’t open the text input state when user press ENTER.

If you don’t like the text field show yellow frame, just write down the below ActionScript.
_focusrect = false;

So you need to use another way to indicate which was focused item.

Below means include numbers 0-9, “:”, and “/”, it will increase 2-3 kb when export to swf file.

You can select “Auto Fill” to add the characters used in this text field, but if you dynamic provide data to it, and you need to add the characters manually.

PS. Flash Lite will add one time when you use the same character with the same font, but you need set each text field which use it.

You can use slash or dot syntax,

If you use slash syntax, just write down below Action Script in the button.
on(keyPress “＜Up＞”){
tellTarget(“/”){
content.scroll–;
}
}

If you would like to use dot syntax, you need to covert the text field to a MovieClip.
on(keyPress “＜Up＞”){
_root.page_mc.content.scroll–;
}

Please notice the text field’s height, if your device use different font, maybe it will show uncompleted content.
