The Android apps that we use today have changed the way we communicate or interact with the whole world just sitting at one place. The Android app developer jobs has become more necessary, enriching and fulfilling to this modern global economy. It wouldn’t be wrong if you think Android app development is one of the coolest jobs at the moment.

Necessary Tools for Android App Development

An Android application can be developed on different operating systems like Windows, Mac or Linux. The list of tools that you require to develop Android applications are listed below:

  1. Java Development Kit                                                                                                                                                                                                                                                                                                                                              Java Development Kit (JDK) is the collection of tools such as Java Virtual Machine (JVM) and Java Runtime Environment (JRE) that were required to write, compile and run any applications written in Java programming language. Java is the basic building block of Android app development. To build any Android application, you must have good knowledge of Java and its key features                                                                                                                                       
  2. Android Studio

    Android Studio is the official Integrated Development Environment (IDE) for Android app development based on IntelliJ IDEA. This IDE offers more exciting features that helps to enhance the productivity while building apps. This official IDE is available at https://developer.android.com/studio/index.html with no cost involved for building apps on all types of Android devices with different screen size and resolution.

Terminologies Related to Android

  1. XML

    In Android, XML is used for designing the application’s UI like creating layouts, views, buttons, text fields etc. and also used in parsing data feeds from the internet.

  2. View

     A view is an UI which occupies rectangular area on the screen to draw and handle user events.

  3. Layout

    Layout is the parent of view. It arranges all the views in a proper manner on the screen.

  4. Activity

     An activity can be referred as your device’s screen which you see. User can place UI elements in any order in the created window of user’s choice.

  5. Emulator

    An emulator is an Android virtual device through which you can select the target Android version or platform to run and test your developed application.

  6. Manifest file

    Manifest file acts as a metadata for every application. This file contains all the essential information about the application like app icon, app name, launcher activity, and required permissions etc.

  7. Service

    Service is an application component that can be used for long-running background processes. It is not bounded with any activity as there is no UI. Any other application component can start a service and this service will continue to run even when the user switches from one application to another.

  8. Broadcast Receiver

    Broadcast Receiver is another building block of Android application development which allows you to register for system and application events. It works in such a way that, when the event triggers for the first time all the registered receivers through this broadcast receiver will get notified for all the events by Android Runtime. To know more about the broadcast receivers, kindly refer Android Basic Building Blocks.

  9. Content Providers

    Content Providers are used to share data between two applications. This can be implemented in two ways:

    1. When you want to implement the existing content provider in another application.
    2. When you want to create a new content provider that can share its data with other applications
  10. Intent

    Intent is a messaging object which can be used to communicate between two or more components like activities, services, broadcast receiver etc. Intent can also be used to start an activity or service or to deliver a broadcast messages.
