Sound
Flash Lite for 505i phones does not support the standard Flash Player audio formats—Raw,
ADPCM or MP3. Instead, only MFi (Melody Format for i-mode) is supported. In addition, each
manufacturer’s 505i phone supports the standard MFi format, plus its own proprietary
extensions.
Flash Lite does not support streaming sound, sound mixing, or looping of sound. Only event
sound is supported and only one sound can be played at a time.
For detailed information about embedding sound into Flash Lite movies for i-mode phones, see
Chapter 3, “Sound,” on page 15 .
Network access
The Flash Lite specification for i-mode supports the
getURL()
function in a restricted manner.
The
getURL()
function is ignored unless the user first presses one of the following keys: 0-9, *, #,
or the Select key. Only the first
getURL()
call in a keypress statement block is executed; all
subsequent
getURL()
calls in the same block are ignored.
The
getURL()
function can be used to load another SWF or HTML page (
http
), a secured (SSL-
Secure Sockets Layer) HTTP page (
https
), send e-mail (
mailto
), or dial a phone number (
tel
).
Screen size
The i-mode phone screen size is one of the most important factors to keep in mind when
developing Flash Lite movies for i-mode phones. Generally, content looks better scaling up, rather
than scaling down, so it is best to create content for the smallest screen area. The screen area
available to Flash Lite varies from phone model to phone model, and across the applications
featuring Flash Lite. In order for a Flash Lite movie to look the best in the browser on all 505i
phones, a resolution of 240x240 is recommended. The screen area available to Flash Lite in the
My Picture and Standby Screen applications varies depending on the specific 505i phone.
Detailed information on the screen area available to Flash Lite on i-mode phones is available on
the DoCoMo website. (See
Appendix D, “References,” on page 47 ).
Movie size
There are limitations on file size and run-time memory usage for Flash Lite movies running on i-
mode phones. There is a prescribed limit on how large a web page can be, whether it includes
Flash Lite movies or not. For 505i phones, this limit is 20KB. Full details can be found at the
DoCoMo website (see
Appendix D, “References,” on page 47 ). This limit applies to an i-mode
page’s HTML, SWF content, and all graphic images combined. Web pages larger than this limit
cannot be downloaded to an i-mode phone and no error message appears. This limitation also
applies to Flash Lite movies played directly in the browser without being embedded in an i-mode
compatible HTML file.
The run-time memory available to Flash Lite movies running on i-mode phones is limited and
may vary from model to model. Generally, for the 505i phones, this limit is not less than
200KB. Because Flash MX Professional 2004 does not provide a mechanism for checking a
phone’s run-time memory consumption, Macromedia strongly recommends that you test all
content on actual i-mode phones.
