Functional Implementation for Android App
This involves the controlling of application state, saving the settings and launching of a specific activity. These activities are achieved by the Android Application Development through the below mentioned steps:
Using the Android Application context – The application context is used for accessing the settings and the resources that forms a part of multiple activity instances.
Retrieving of Android Application Resource – The method of retrieving a resource in the android application development would involve the usage of the unique resource identifier.

These includes launching of activity instances, retrieval of assets package of the android application, request for system level service provider, management of private application files, inspection and enforcement of application permissions
Working with the Android Activity – This would involve the implementation of android activity for every screen of android application.
Launching of Android Application activity – Launching of the Android Application Development could be conducted through designating launch activity within the manifest file, launching through the activity context and launching of the child activity from the parent activity.
Management of the activity state – Android application manages their own state, which includes the memory, resource and data. This means that the activity of the android application which is not in use would face automatic shut down.
Implementation of activity callback – Activity call back methods like on create, setting layout with set content view, on resume, on pause, stop audio, video or animation and on destroy.
