What is android software development?
Android software development is a branch of software engineering that focuses on developing applications for Android-powered devices. Android development may involve a variety of programming languages, and there are four main components of an Android app that allow it to function.
Which language is used in android software development?
Most Android APIs are designed to work with Java, which is also the default coding language in Android Studio.
Four main components of an android app
- The activity is the single-screen user interface that serves as the user’s entry point for interacting with an app. Independent activities collaborate to create a unified user experience and are in charge of facilitating key interactions between the system and the app, such as keeping track of what is on the screen to ensure the system continues to run the process hosting the activity. This prioritizes previously used processes in order for the user to return to them, allowing apps to restore previous states after being killed and to implement user flows between them.
- Services serve as a general-purpose entry point for running an app in the background while another app is running or the user is not actively navigating the device. Music playing in the background while a user is in another app is an example of a service. Services are classified into two types:
- Services that have been started, which keep an app running in the background until its process is complete.
- Bound services that continue to run because another app or the system relies on them to function
- Content providers
- A content provider manages shared sets of data that can be saved to the file system and accessed later by an app. Approved apps can query or modify data from content providers. A content provider that manages a user’s contact information and allows apps with the appropriate permissions to query the content provider and read and write information about a specific contact is an example.
- Broadcasts receivers
- A broadcast receiver enables the system to send events to an app that are not part of its normal user flow, such as system-wide broadcast announcements. An app scheduling an alarm to notify the user of an upcoming event is an example of this. The app can send that alarm to the broadcast receiver, allowing it to remain closed until the alarm sounds. Broadcasts are frequently sent by the system itself, informing users of things like system shutdowns, low battery levels, or when a picture has been taken.
The platform provides app developers with structured code modules that allow them to divide projects into functional units for independent building, testing, and debugging. It is capable of intelligent code editing with advanced code completion, refactoring, and code analysis, as well as a feature-rich emulator, code templates, a layout editor, and other tools.
