Benefits of Using Android OS in Mobile Phones
Growing demand of smart phones and mobile phone devices has increase
the demand and popularity of Android application development these days,
and as a result of this there are lots of companies which are available in the
market which are developing android applications.

2. Android has become a need rather than luxury these days, and its popularity
has increased rapidly among the smart phones. Android App Development is
nowadays has become an important tool for developing mobile applications.
There are lots of OS which are available these days but among all of them
android is the best one, as it can be handled easily and also it is very easy to
implement because of its open source nature. The (SDK) facilitated by the
Android assists the developers to start developing and working on the
applications instantaneously and the app can be implemented faster. Android
is a product of Google and it is owned by open handset alliance group.
The android mobile platform constitutes of an operating system (OS), the
middle ware, main applications, and a (SDK). The SDK facilitates the
developers with the APIs and tools needed for Development. The distribution
platform is of an open nature which allows the android developers to develop

Android is an open source operating system for mobile devices that offer
numerous possibilities for developers who want to make a unique user
friendly applications in the industry of mobile applications. The developers

mobiles such as Bluetooth, Display, Views, etc.
Requirement for the project:
1. In Android mobile there will be an application which shows different colors

4. 2. The phone will be interfaced with PIC184550 Micro controller using blue
tooth.
3. The PIC will also be interfaced with different color leds (like red, green,
blue, white etc)
4. If anybody opens the application and touch one color in the phone screen,
then the corresponding LED should glow.
