MIDP (Mobile Information Device Profile), like the
CLDC (Connected Limited Device Configuration), is a specification
document. The MIDP is the API (Application Programming Interface)
that sits on top of the core to let you do interesting things on a mobile device
(handheld, cellphone), such as the user interface. version 2.0, MIDP-2, adds multimedia and gaming, over-the-air and end-to-end
is not compatible with AWT (Advanced Windowing Toolkit) or Swing. It uses the
stripped down javax.microedition.lcdui api as its
GUI (Graphic User Interface). Personal profile in common on
PDAs (Personal Digital Assistants)
and PDA/cells. MIDP
in common on pure cellphones.
application has some jar files each with a MANIFEST.MF, similar to an application manifest and a jad file which lists the midlets and jars for a bundle.
How does Software get into a Cell Phone?
If the phone has Internet access, I presume it is possible to download the
jad file (mime text/vnd.sun.j2me.app-descriptor) from an ordinary website given the
URL (Uniform Resource Locator).
If the phone has WAP (Wireless Application Protocol) access, you upload the
jad file to a host. Your app gets assigned a number. Anyone
wanting to load the software uses their cellphone wap browser to navigate to the
site and enters the number.
Each phone may have a proprietary way to upload code over a proprietary cable,
sometimes called a conduit, with proprietary software
from a desktop computer. For example, for Sanyo, the software is a
add on. Nokia uses PC-Suite. Some phones let you upload with Bluetooth. Some
phones let you upload over in infrared link. Some phones look like a
USB (Universal Serial Bus) storage device (flash drive) to the desktop. Some
phones you program by plugging a memory card into them that you have loaded with
your memory card writer slot.
