Part I: The Nuts and Bolts of Android
Market share
As a developer, you have an opportunity to develop apps for a fairly new
market that is booming on a daily basis. Android is currently set to outpace
many other carriers in market share in the industry in coming months. With
so many users, it’s never been easier to write an application that can be
downloaded and used by real people! The Android Market puts your app
right into your users’ hands easily! Users don’t have to go searching the
Internet to find an app to install. They just simply go to the Android Market
that is preinstalled on their device, and they have access to all your apps.
Because the Android Market comes preinstalled on most Android devices (I
discuss a few exceptions later), users typically search the Android Market for
all of their app needs. It’s not hard to see an app’s number of downloads soar
in just a few days.

Time to market
With all the application programming interfaces (APIs) that Android comes
packed with, it’s easy to develop full-featured applications in a relatively
short time frame. After you’ve signed up with the Android Market, just
upload your apps and publish them. “Wait,” you may say, “are you sure?”
Why, yes, I am! Unlike other mobile marketplaces, the Android Market has no
app-approval process. All you have to do is write apps and publish them.

Technically, anyone can publish anything, but it’s good karma to keep within
Google’s terms of service and keep your apps family-friendly. Remember
that Android users come from diverse areas of the world and are in all age
categories.

Open platform
The Android operating system is open platform, meaning that it’s not tied to
one hardware manufacturer and/or one provider. As you can imagine, the
openness of Android is allowing it to gain market share quickly. All hard-
ware manufacturers and providers can make and sell Android devices. The
Android source code is available at http://source.android.com for
you to view and/or modify. Nothing is holding you back from digging into
the source code to see how a certain task is handled. The open-source code
allows phone manufacturers to create custom user interfaces (UIs) and add
built-in features to some devices. This also puts all developers on an even
playing field. Everyone can access the raw Android source code.
