Who is an Android developer?
An android developer is a software developer with proficient skills and knowledge in creating and developing software-based applications for mobile devices- which must be compatible with all types of devices, such as systems, desktops, tablets and mobile phones.
The android developer is involved in the android development process for creating software code, executing backend services and testing the application on various devices. Many top companies focus on android development because it is an ever growing and never daunting industry. The purpose of sourcing new and updated mobile apps by the organization is to reach the world wide people and numerous people through Google Play Store. The android operating system is used in Google devices and other OEMs.

Now, we shall discuss 10 skills you need to succeed as an Android developer.
Android foundations
The essential skill required for an android app developer is a programming language. Most developers prefer to choose Java and Kotlin. So developers can choose either Java or Kotlin or even both for application development. Android development with java would be the best choice for many developers.
If you intend to learn programming language, you can join Java Training in Chennai and learn the core concepts of Java such as Data Types, Operators, Variables,Methods, Objects, Constructors, Strings, etc.
So, suppose you intend to become an android developer. In that case, you must have an in-depth understanding of any programming and its core concepts, such as syntaxes, collection framework, concurrency and multithreading, generics and functional programming.
To design a user interface layout in Android, the developer can use XML. Like hypertext markup language, extensible markup language is also a markup language. After creating this extensible markup language, Layouts are linked to Java/Kotlin files where business logic is written.

There is a useful tool called Android Studio that allows you to create fluid XML layouts and write procedural code in an integrated environment. Gradle, an advanced build toolkit, is used by Android Studio to automate and manage your build process. There is a plugin called the Android plugin for Gradle that allows you to integrate Gradle with Android Studio.
Before you can begin, you must comprehend what Gradle is and how to utilize it specifically for handling dependencies.
In Android Studio, Gradle and Android plugins can run independently. So, you can build Android apps with the in-built feature of Android Studio.
Android interactivity
In the android app development, user interaction with the android app will be given priority. A seamless user experience largely depends on using callbacks to respond to events, implementing appropriate gestures like drag and drop, providing the correct keyboard for user input, and utilize pan and zoom appropriately. Although very small, these are very helpful in enhancing user interaction. Above all, the Activity component of Android is where this user interaction takes place.
A user can perform a single, narrowly focused task activity. The Activity class keeps track of creating a door for you to locate your user interface since almost all Activities interact with the user. For the Android device, various screen configurations are available. Screen orientation is one of them. There are two possible orientations: portrait and landscape.
There are versions of each Activity in both portrait and landscape orientations. The current Activity is destroyed when the screen is turned and recreated in a different orientation. Always maintain an Activity's stability when the screen's orientation changes.
Android User Interface
The application process will only be complete with the user interface. So, if you are creating an android-based app, it must have the main component and functionalities. If it fails to adapt to the new technology or does not meet the essential requirement, your effort will end up in vain. So, if you are an android developer, keep updating yourself and adapt to the new trends.
When designing layouts, it's important to remember to account for different screen sizes. The same app should behave differently on other devices. For example, the tablet's screen should show dual-pane layouts to utilize a widescreen fully. On a smartphone, a single pane is used. This behaviour can be achieved using fragments. Additionally, you might need to alter Views in several situations to suit your needs. You can do this by developing distinctive components for your Views.

Implementing navigation
While building an app, navigation is crucial in interaction, which allows the user to navigate from one piece of content to another within the in-built feature of the app. So, integrating multiple User Interface elements will enable you to execute effective User Interface navigation.
The app bar, also known as a toolbar, is the most fundamental. A popup menu, menu icons, and a navigation drawer icon can all be added to your toolbar. You can use this icon to open and close the navigation drawer, which is another component of effective navigation.
You can add better menu items to the navigation drawer, which can be used to swap out pieces of your current Activity or carry out other necessary operations.
A BottomNavigationView is another navigational element that lets you switch between different Fragments within the same Activity by utilizing tabs at the bottom of the screen. If you swipe between Fragments and use tabs attached to the Toolbar, ViewPager is the best option for you.
User intention is the most crucial part of navigation. A new Activity, a previous Activity, or even sharing data with another app may be what the user wants to do. These intentions can be carried out using Android Intents feature. If you are aware of your target Activity, use Explicit Intent; otherwise, use Implicit Intent. Your intentions can be configured whenever you want.
Above all, the Navigation component of Android Jetpack assists you in implementing navigation, from simple and direct button clicks to more complex patterns like app bars and the navigation drawer. Before you begin implementing navigation in Android, take a look at this component.

Android Testing
The end user will interact with your app at different levels, like pressing buttons, dragging, dropping, selecting and many other activities. As you iteratively develop your app, you should evaluate various use cases and interactions. The most widely used testing libraries are:
-
UI Automator
-
Expresso
-
Robolectric
-
Mockito
-
Junit
Working with data
Your application's data is an essential component that cannot be neglected. You should manage files, store user preferences, retrieve data from the server, and run queries against the local database in addition to handling files.
You can choose the Room database if you intend to utilize the local database. The room database is a component of Android Jetpack's architecture. Using ContentProvider, you should share your database with other apps securely.
Use Jetpack's DataStore, which uses Kotlin coroutines and Flow to store data, to save small amounts of data like key-value pairs or typed objects.
Use the Data Binding Library to declaratively bind your UI elements in your layouts to a data source in your app.
You can use the extensive file system APIs made available to you to manage files in your app. Above all, use the Retrofit 2 library to access network data, which Jake Wharton has made available to all Android developers.
If you are interested in learning Kotlin programming language, you can join Kotlin Training in Chennai, which will help you understand functions, variables, OOPs concepts, collections of Kotlin.
Notifications
Notification is the best way to boost user attention. Outside of the user's user interface (UI), your app will display reminders, messages from other users, and other notifications. Users can click the notification to open your app or carry out a task there and then. An alert can be created, have its layout customized, actions added to it, and multiple alerts grouped using notification channels.

Firebase on Android
If you dislike becoming a backend developer, Firebase on Android is the best way for you. Firebase is the best android app development platform which helps you build a compelling app with high quality.
This also helps you grow your user base and income. Firebase provides several valuable features for the comfort of Android developers.
Moreover, Make your app visible in Google searches by using the Firebase App Indexing API. Utilizing cloud storage and cloud firestore will allow you to store data on your server. Use Cloud Functions to automatically execute backend code in response to events brought on by Firebase features and HTTPS requests.
The Firebase Cloud Messaging (FCM) feature comes next, allowing you to notify your clients. You can alert a client app that new email or other information is available for updating by using FCM. Utilize Firebase Crashlytics, a legitimate crash reporter that is small and lightweight that enables you to identify and address stability issues. Try Dynamic links if you've ever used deep links in your app. When you use dynamic links, your users receive the best possible experience for the platform.
Android security
Android has an in-built security feature that remarkably lessens the impact of application security problems. You can shield the user's confidentiality by using permissions. So, with this feature, users can share information securely by utilizing signature-based permissions. Moreover, it is compatible with handling data security by internal and external storage and content providers. Never, unless necessary, export an Android component like a ContentProvider, Service, or BroadcastReceiver.
Android has WebView, which has minimum functionality to prevent web security issues like cross-site scripting. You should still limit how often you ask users for their login information. Use an authorization token in its place, and refresh it often.
Git: Version control system
Git is open-source, free software that is used for version control. Git enables you to try out new application features and coding approaches confidently. You can quickly go back to the previous version of your project when you realize you need to evolve it in the right direction. It is the best feature that GitHub has.
