INTRODUCTION
 A Software platform and operating system for

 Based on the Linux kernel.
 Android was found way back in 2003.

 It’s the only way to transfer data between applications in Android
(no shared files, shared memory, pipes, etc.)
Other applications use a Content Resolver object to access the data
provided via a Content Provider

kits
Java – Android Studio (ADK)
Python – Kivy

security applications

Features & Limitations
Features
Android has built-in services like GPS, SQL
Database, browser and maps
Support optimized graphics VGA, 2D and 3D
graphics
Low investment and easy to develop
Integrating inter-applications

Limitations :
 Ui problems- not following a common Ui process in
app development
 s/w fragmentation – several vers available for diff
devices. It is not comfortable for many users to
upgrade since manufacturers play a vital role in
device configuration
 Copyright Issue – No particular quality check rules
for uploading apps in android
 Uses more battery when compared to java and
symbian mobile phones

Conclusion and Future
Scope
 Android applications stepping up not only in mobile internet but also in
