What is Android Development?

Any application developed to be supported by the Android Operating system using the android software development kit (SDK) on android studio is the process of android development. The open-source operating system designed by Google, especially for mobiles is Android. Android OS has been developed using Linux Kernel. Because of the ability of easily modifiable (as it’s open source), most android developers have used different GUIs even when all of them use the same basic operating system. The open source code used for the development of android applications is the Android Open Source Project (AOSP), Any application for the android systems can be easily created by installing the freely available SDK. These applications support any device which is built in android OS and written In Java. These run on Java Virtual Machines (JVM).

Programming languages

In my experience, you need to have a firm grasp of Java to develop Android apps. Knowledge of Kotlin and C++ languages can also help. You can also choose to develop an app with other languages using a tool. Doing this however may restrict your API access.

API Level

As android has different versions in the market each having distinct features, the main asset behind it is the Application Programming Interface (also known as API) Level which is the specific API framework identifier. Different versions of Android have different features and advancements.

Android Architecture for development:

The Android architecture starts with the main user interface which supports the front end of the android applications; these can include applications such as calculators, clocks, Emails, alarms, etc.

The second layer of the android architecture is the android framework which consists of the windows firewall, service providers, and all the various managers such as packages manager and activity manager, etc. The third layer consists of the Libraries and Android runtime which consists of SQL, SSL, SQLite, Lib-c, etc. The lowest layer of an OS system consists of the Kernel which has all the drivers such as the Wi-Fi driver and Bluetooth driver etc.

Android Development Basics – Libraries:

The libraries are the basic tools for the development of android applications. Some of the libraries used in android development and their main features are:

    1) Android. app

    2) Android. content

    3) Android. database

    4) Android.OpenGL

    5) Android. os

    6) Android. text

    7) Android. View

    8) Android. widget

    9) Android.WebKit

What is Android Application Framework:

The Android applications are created in the dedicated IDE Android Studio, using which any specific resolution can be set for any version of android. The front-end high-level services are provided by the Application framework – Java in the form of classes. The basic activities in the android application framework are:

1) Activity Manager

2) Content Providers

3) Resource Managers

4) Notifications Managers

5) View System. (Layouts)

Why build Android apps?

Android is the largest mobile OS in the world in terms of market share. To reach a global audience, your best bet is to build an Android app that works on mobile devices.

    1)  A large audience. Android is used by 3 billion users in the world.

   2)  As it’s open source, you can customize Android any way you like. This is a great way to build different types of applications.

   3) Geographically, Android is ubiquitous across the world compared to other mobile operating systems like iOS.

    4)  Most major smartphone manufacturers run Android on their devices.
