Mobile devices have seen an extensive amount of
development in recent years, but one question is still
looming and nobody seems to have the answer: what is
’standard’ for the mobile platform?Many companies have
already written their own in-house operating systems for the
devices they manufacture such as Symbian or iPhone OS.
However, with the existence of so many closed-source
operating systems, no rational company would want to
disclose their secrets and lose their edge on the competition.
This presents a problem where software developers can’t
write their code to be generalized. The Android team hopes
to solve this on two levels. Firstly, it seeks to arrive at a
common open-source operating system that any mobile
device can run on. Secondly, it seeks to make developing
applications for these mobile phones more general and
hardware-agnostic.

Android is a truly open, free development platform based
on Linux andopen source. Handset makers can use and
customize the platform without paying aroyalty. A
component-based architecture inspired by Internet mashups.
Parts of oneapplication can be used in another in
ways not originally envisioned by the developer. can even
replace built-in components with own improved versions.
This will unleash a new round of creativity in the mobile
space.
