About IDE:

We are using android studio here. Android Studio is the official integrated development environment (IDE) for Google's Android operating system, built on JetBrains' IntelliJ IDEA software and designed specifically for Android development. It is available for download on Windows, macOS and Linux based operating systems or as a subscription-based service in 2020. It is a replacement for the Eclipse Android Development Tools.

Android Architecture

What is Android Architecture?

Before studying the Architecture, let us go through some of the features of the Android Operating system.

1. Android OS can be customized as per the need, and hence we can notice many avatars of this OS are deployed in different mobile devices with multiple unique features.

2. It supports all mobile connectivity technologies viz., Wi-Fi, CDMA, GSM, NFC, Bluetooth etc., and basic functionalities like telephony, SMS and data transfer. With this connectivity, data can be transferred back and forth between devices thru various apps.

3. It provides Interfaces (APIs) that support location dependent services such as GPS.

4. SQLite database provides storage functionalities needed by Android. Being a lightweight database, it enables simpler storage and quicker retrieval of data.

5. It supports all versions of multimedia files (Audio/Video) and integrates a Microphone, Camera, Accelerometer and speaker for effective management of recording, playback operations.

6. HTML5 and CSS3 are supported for the development of an intuitive and impressive front end screen.

7. It allows multiple windows to be active at a time, performing different tasks.

8. Graphics 2D/3D are supported.

9. Supports NFC technology that enables connectivity between two NFC enabled devices just by touching devices with each other.

10. Multi-languages support, User-adjustable widgets, Google cloud messaging are the other features.

What are the components of an Android application?

There are some necessary building blocks that an Android application consists of. These loosely coupled components are bound by the application manifest file which contains the description of each component and how they interact. The manifest file also contains the app’s metadata, its hardware configuration, and platform requirements, external libraries, and required permissions. There are the following main components of an android app:

1. Activities

2. Services

3. Content Providers

4. Broadcast Receivers

5. Intents

6. Widgets

7. Notifications
