Brief Architecture of the proposed application:
The Android operating system is divided into five sections and four layers.
The architecture of Android operating systems:
 Application
 Application Framework
 Libraries
 Linux Kernel
 Android Runtime
The above mentioned five android operating system architecture is most important to build an
android application. Our food consumption android application is developed under the
guidance of these all architecture. This Android operating system architecture provides the best
mobile device compatibility. To make effective Android application developers have to be
aware of that architecture of the Android operating systems. The kernel of the Android
operating system is written in Linux and the Android operating system is written in C language.
C language very first programming language in the computer world.
The architecture of our food consumption android application is also based upon the above
android operating system architecture. As the introduction of this mobile app cleared that this
android application is based upon the food consumption process. The architecture of our
Android application is very efficient and very easy to use. Our food consumption android
application having a homepage describing the name of the application and some function of
this app. In the footer of this android application, we have some function icon to use the
application. We have defined some launched icons in our android application such as user icon
and menu icon and others.
The architecture of application:
 In our food consumption android application, there is a home page describing the name
of our android application and some launched icons. The launcher icons are given in the
footer area of the application. The user of this android application can easily understand
the function of the application seeing this launched icons.
 In the user profile area, there are authentication features is given in our food
consumption android app. If the user is already signed in the app then the user has to
click on the login button to get the access of this android application. But if the user is
new on this food consumption android application then the user has to sign up to get
authentication in this android application. This android application gives an extra login
facility by directly accessing your Facebook account. After login with your Facebook
account, the user will get direct access to this food consumption android application.

 To maintain the diet plan there is an additional feature of e-diary where the user can
directly write the diet plan and can save the plan in the application.
 In this android application, we have used activity and fragments to make the app more
attractive. The fragments define the better user interface and very effective also. The UI
of this android application is designed under the efficiency of every generation users.
 The most attractive part of this food consumption architecture is that gives the
functionality of online storage in our diet plans. Suppose the application uninstalled
from your android devices then you can’t able to restore your e-diary. This food
consumption android application gives the online storage of your diet plan over the
Dropbox, mail, and googles drive also.
