In-Depth Information
There are many Symbian smartphones. In many cases, giving a single
answer that applies to all models, versions, manufacturers, and so on,
is not possible. Attempting to give such an answer is simply is not the
right approach. Instead, our intention is to direct you towards asking the
right questions and to equip you with the right mindset, approach, tools
and the relevant information sources. Knowing what you know, you can
safely steer yourself in a direction appropriate for you.
So let's start the journey. There is fun to be had!
3.1 Running a MIDlet on a Symbian Smartphone
(not another 'Hello World')
Being able to deploy and run an application on a target Symbian smart-
phone is a prerequisite for any discussion or development.
A Symbian smartphone can be built on different versions of Symbian
OS, can come from different phone manufacturers, can have different
form factors and different UI designs. For that reason, we choose three
devices that represent the different flavors of Symbian smartphones that
are currently in the market (see Figure 3.1). The Nokia N95 is an S60
3rd Edition device that can be operated with one hand; the Nokia 5800
XpressMusic is an S60 5th Edition device with a resistive touch screen
and tactile feedback; the Sony Ericsson W960i is a UIQ 3 device with a
touch screen.
