Android application architecture allows the simplification and reuse of any application. It provides a better way to publish the capabilities of the application so that any other application can make good use of those capabilities.

This architecture includes the following components:

☆ Intent to perform some operation on some activity and service

☆ Resource Externalization - such as strings and graphics

☆ Notification signaling users - light, sound, icon etc.

☆ Content Providers - sharing of data between various applications
