How
to develop android app?
This will certainly come to your mind, if you have boiling business
idea or you are running a business. Android is the operating system
that brought in revolution in the world of Smartphone and mobile
application. Through Android, Google targets to emerge in the world
of low cost smart phones. Have you ever thought of developing an
Android App? As per the Android
Application Developers,
developing
an android app
is an easy task. Before getting into the different phrases of
developing android app, it is essential to gain knowledge about
android app.

What
is Android App?
Android
App is a software application, which is developed operate and perform
on Google's android platform. Android application could be easily
available in different platforms like Google Play store, Amazon App
stores and various sites specific to Android Apps. These Android apps
are compatible with smartphone, tablets and Google TV, operating on
Android Platform.
Development
of Android Application
An
App developer has the capability of developing
mobile application
on android, iOS and windows OS. Here we would concentrate on the
development
of an android application
for the Google's android operating system. At present there is an
increase in the demand for the low-cost Smart phones. Along with the
rising demand of the smart phones, the demand for the mobile
application for these phones has also increased. Let’s go through
the whole process of development of an application on the most used
mobile platform called Android OS.
Step
1 – Designing the features of the Android Application (For example,
an android
game development
is considered here)
The
designing of the android app consists of following five steps. These
steps are
Splash-
This is the first screen that the user will be able to view that
would comprise of the logo of the android application, the version of
android app and any kind of music depending on the requirement.
Menu-
The menu screen of the android application would provide the user
with the option like playing the game, viewing the current score,
viewing the previous score and instruction regarding the operation of
the android application.
Play-
The user would be taken to this screen when he/she chooses the option
of play from the menu screen. The user can start playing the mobile
application from the play option.
Score-
This screen of the android apps would display the highest score by
the current user, the score of the previous user and the last option
would be challenging the current user to improve the score by playing
the android game for one more time.
Help-
The option in the android
application development
provide the user with the instruction in regards to playing of the
game. The option would also enable the user to refer to different
kinds of query that he has in regards to playing of the android
application.
Step
2 - Determining the Android App activity requirement
The
requirement for each activity has to be determined. The splash
activity acts as the default activity used while launching
the Android Application.
The menu activity comprises of different button each corresponding to
a particular feature of the application. The play activity is
involved in drawing onscreen drawing of stuff, handle the various
user inputs, and keep the score following the game dynamics as per
the android application developer. Score activity is concerned with
loading of score screen to the android application. Help activity is
involved in the display of help text instead of displaying the score.
Step
3 - Implementation of functionality of the application
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.
Accessing
the Android Application preference – Shared application preference
could be retrieved by implementing the “get shared preference”
method of the android application context.
Accessing
the functionality of other applications- The application context
could be used for many other activities for android application
development. 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.
Android
Application Development
& android
game development
could take place with the implementation of three components namely
context, intent and activity.
