3- Android platform

The Android platform consists of three main parts: the hardware part, the operating system part, and the application part. In the following, we explain each of these sections.

Hardware section

This section includes all the hardware parts of the Android device, such as the processor, memory, camera, display, and other parts. This part performs hardware operations such as processing, storing, displaying data, and communicating with other devices. For applications to be able to communicate with this section and use them, they must be familiar with how to work with the device’s hardware and use the relevant APIs.

Operating system section

This section includes the Android operating system installed on the device and is responsible for managing and controlling the device and running applications. Android operating system based on Linux

Set and provide an interface for communication between the hardware and application parts. This section includes codes related to devising boot, hardware resource management, network and communication management, security management, energy and battery management, and other operating system-related tasks. In fact, this part of the Android operating system allows applications to communicate with the hardware and access device features such as the camera, GPS, and sensors.

Applications section

This section includes all the applications that are installed on the Android device. Developers can develop applications using various programming languages and tools and publish them to run on Android devices. These applications can perform various tasks such as sending messages, managing calendars, playing music and videos, browsing the web, playing games, etc. Also, applications can access and use the device’s features using Android OS APIs. Applications and developers can also use the SDK and development tools to manipulate and make changes to the functionality of the Android operating system and provide applications with special and varied features. This section acts as an interface between the user and the Android operating system, executing and displaying all the user’s actions.

4- Programming languages

Android apps can be developed using Java and Kotlin programming languages. Also, by using NDK (Native Development Kit), programmers can also use C and C++ languages.

In Android, various programming languages can be used to develop Android applications. In general, programming languages for Android are divided into two categories: Java and non-Java.

Java is the main language for developing Android applications and is supported by Google for developing Android applications. Also, languages like Kotlin and Groovy are used to develop Android applications. Kotlin is a modern and reliable language supported by Google and was introduced as the official second language for Android application development. Groovy is a dynamic programming language used to develop Android applications.

Besides, non-Java languages such as C and C++ are also used to develop Android applications. These languages are used natively and are suitable for developing high-performance programs and special applications such as games.

In addition, languages like JavaScript and Python are used to develop Android applications. In this case, these languages can be used using frameworks such as React Native or Kivy. These solutions help developers develop cross-platform apps for iOS and Android using non-Java languages.

5- Default programs

Android has many default apps provided by Google and various Android device manufacturers. Some of these default programs are:
