The tutorial will help you understand an Android application’s different components. Any Android application must have four components. The article below will guide you through the process of understanding each component and implementing them in Android Studio.
What is an Android Application?
Android applications are software programs that run on Android devices and can perform several functions. Android applications can be built using any one of these programming languages.
- Java
- Kotlin
- C++
You should use Android Studio for Android mobile app development and choose from the abovementioned languages. An Android application comprises four essential components and several additional components. Each of the four components has a distinct purpose and a lifecycle. The four components define the path users and systems can take to start or exit an application.
Android Application Components
- Android Activity
The Activity screen is always the first to appear when a user launches an application. The user can interact with the application through this screen. This screen can appear in several applications. Each activity comprises UI components of Android application that assist the user in determining the action he wishes to take. Each activity is distinct and has its life cycle.
Imagine, for example, taking a photo and sending it directly to a friend. You switch from WhatsApp to the Camera Activity. This doesn’t mean that WhatsApp is deleted, just paused. The Activity Manager manages all of these things.
- Android Services
Service processes do not allow any user interface to interact with them. The service runs quietly in the background to perform the task. The services can be running whether or not the application is open. The services are an important component that allows the user to do various things like play music, trigger notifications, receive warnings and more. For instance, you left your music app open and returned to it. The background music will continue to play even if you exit the application.
Your messaging app is another example. You will still be notified of any messages that arrive on your device, even if you do not have your messaging application open. Have you been thinking of an Android app for your business? In that case, WP Bunch, an Android application development company in India, can help you.
- Android Content Providers
The Content Provider acts as an intermediary for various applications to communicate. It looks after the applications’ data and connects to the SQLite Database. It only provides exclusive data for the application user and doesn’t allow access to other data. The content provider is the only one who can access data. When you need data from another application, the content provider will ask the user for permission.
You will often see your gallery as an example. When an application wants to use some images from your gallery, the app asks for permission, and then the content provider sends you the necessary content.
- Android Broadcast Receivers
This is one of the main components of Android application. The Broadcast Receiver’s job is to accept any intents other applications may send. The receivers respond with a specific behaviour to these intents. Broadcast receivers are used to inform users about any application or process. The user can be notified through the status bar or notification. Not all notifications require your application to be running. These broadcasts were usually system-generated and did not require an app user interface. Alarm applications are the most popular example. You close the application when you set an alarm. You receive a notification at a specific time.
Android App Development: Additional Features
The Android application development includes several additional features:
- Intentions
Android applications are powerful because of their intent. This allows different applications to talk with one another. The intent carries the information about which activities should be stopped or destroyed. Even the intent is used to move data between activities.
- The Widgets
One of the major benefits of Android application is the widgets. The widget is a component of design and customization. You can see widgets such as clocks, weather and more on your home screen. You can change your device’s home screen appearance with these widgets and easily access certain frequently used items.
- Views
Views can be used to design and handle events. Views are used in both coding and designing. We can use views to describe the behaviour or interaction of an element with the user.
- Notifications
The notification alerts users to any updates or new announcements by application providers. The notification can appear in the foreground and background of an app. A notification will still be sent even if you don’t have the app open.
- Fragments
By creating an activity, you can provide multiple functionality. You can perform multiple tasks within the same activity by using fragments. The fragments are reusable, and they can be applied to different activities. This fragment is composed of Views, View Pager and other Views.
- File XML
An XML document creates the layout of any Android application. Using XML, we can design or create unique layouts for our app. XML allows data to be transferred from our database into the layout file.
