At present, the Android Platform is only used in Mobile Phones or Tablets, it is not so. In fact, the Android Platform is an operating system developed for small devices like Windows, Linux,Unix, which can be used as a platform in any digital device.

1. What is Android:
That's why At present, the Android app development company in lucknow is only
used in Mobile Phones or not only mobile phones and tablet PCs are coming
based on the Android platform, but Google has also started adding it to set-top
boxes and TVs, which is known as Google TV. In the same way, the Android
Platform has been used as the main platform in various types of other digital
devices such as Cars, Airplanes and Robots. Nevertheless, the Android Platform
was originally developed only for such small screen devices, which do not have
any hardware input device like keyboard, as with computer system, but to input
data to these devices. In this, using their Touch Screens only, Virtual Keyboard is
made on it.Therefore it can be assumed that the Android Platform is going to be
developed basically for Small Screen Devices such as Smart-Phones in the future
as well and this situation is an advantage for us as an Android Developer and also
a drawback.

3. Android App Architecture
When we develop Desktop Application, then we have full control over our
application, under which we can launch the Main Window of our application at
any time according to our need and have any specific Child Window like Dialog in
it. You can open the box.That is, while developing a desktop application, we have
complete control over various aspects of our application, whose various needs are
met by the operating system. Android View – Whatever the user sees on the
screen, it is called User Interface (UI) and it is the responsibility of the Activity to
set which User Interface will be visible in front of the user.
User Interface in any Android App is basically made up of two sub-components,
which are known as Views and Layouts or ViewGroups.
The User Interface (UI) elements of an Android App development company in
lucknow such as Button, Label, Text Box, Radio Button, Checkbox, etc. are called
Views which create the User Interface of the Android App, so that the User can
interact with that Android App

5. Android Activity – The Basic Fundamentals
Android Activity – Activity is a User Interface (UI)
concept that usually represents a single screen of an Android application. There
can be one or more Views on this User Interface Screen as per the requirement
but having Views is not Compulsory. That is, there can also be an Android App
that does not have any View in its Activity.
We can consider an Activity as a part of our Android App, which helps the user to
perform an action. In simple words, Activity is the medium in the form of User
Interface, which handles the various actions that are performed due to User
Interactions.

7. Android Fragment – ​​The Basic Fundamentals
When the screen of an Android App development company in lucknow is so big
that it is difficult to manage all its functionalities in a single Activity, then in this
situation that big Activity is divided into many smaller Sub-Activities. These small
sub-activities are called fragments and an activity can display one or more
fragments on the screen at the same time.
When the screen is small, there is usually only one fragment in an Activity and
the same fragment is visible on a large screen as well.
