I’m here. To be a successful Android developer, you need to develop a variety of skills and apply them at the right place and time to give your users the best possible experience.

Here are 10 must-have skills you need to be a successful Android developer

Android Basics

The most basic building block of Android development is the programming language. Kotlin and Java are the most preferred languages ​​for building Android apps. You can develop apps using either Kotlin or Java, or both at the same time. You should be familiar with the core concepts of one or both of these two programming languages, such as basics and syntax, collection frameworks, concurrency and multithreading, generics, and functional programming.

Android Interactivity

User interaction with your Android app should be your top priority. Responding to events using callbacks, implementing appropriate gestures such as drag and drop, providing appropriate keyboards for user input, and using pan and zoom where appropriate provide a seamless user experience play an important role on These are very small, but very useful for improving the user experience. This user interaction is mostly done in android component called Activity.

An activity is a single focus that a user can perform. Almost all activities interact with the user, so creating the window in which to place the UI is handled by the activity class.

Android User Interface

An application is incomplete without a modern user interface. Applications can contain useful features, but are ultimately doomed to failure if they do not adapt to the latest of UI guidelines.

Implement lists and grids with RecyclerView, design complex layouts with Constraint Layout, apply animations to improve user experience, use proper menus, follow Material Design guidelines, raster graphics using drawable vector graphics instead of graphics is part of the basic rule that every developer should follow. Follow their app.

When designing layouts, remember to consider devices with multiple screen types. The same app should look different on different devices. For example, tablet screens should display a 2-split layout to effectively use the widescreen. Smartphones must use Single Pane. This behavior can be achieved using fragments.

Implement Navigation

Navigation refers to interactions that allow users to move between different pieces of content within your app. There are various UI elements that can be used to implement effective UI navigation.

The most basic is the app bar, commonly known as the toolbar. You can add pop-up menus, menu icons, and navigation bar icons to toolbars. This navigation bar icon helps open and close the navigation bar, another element of implementing effective navigation. A navigation bar allows you to add menu items that help you swap fragments or perform other related actions in the current activity.

Android Test

Users interact with your app on multiple levels, from pressing a submit button to downloading information to their device. Therefore, as you iteratively develop your app, you should test different use cases and interactions. The most commonly used test libraries are Expresso, Junit, Mockito, Robolectric, and UI Automator.

Manipulating Data

Data is an important part of your application and should not be ignored. You may need to retrieve data from servers, query data from local databases, save user preferences, and edit files.

To use a local database, use the Room database which is part of the Android Jetpack architecture components. There are times when you want to securely share a database outside your app using a Content Provider.


Notifications are one of the best ways to increase user engagement. Appear outside the app’s user interface to provide the user with reminders, notifications from other users, or other updates from the app. Users can tap the notification to open the app or take action directly from the notification. You can also create notifications, customize their layout, add actions, and use notification channels to group multiple notifications.

Firebase on Android

If you don’t want to be a backend developer, Firebase for Android is for you. Firebase is a mobile platform that lets you build high-quality apps quickly, grow your user base, and earn more. Firebase provides some utility features to simplify the life of Android developers.

Android Security

Android has built-in security features that significantly reduce the frequency and impact of application security issues. Permissions can be used to protect user privacy. Securely share data with signature-based permissions. Pay close attention to data security when working with internal storage, external storage, and ContentProviders. By default, don’t export Android components like ContentProvider, Service, and BroadcastReceiver unless you need to Android limits the functionality of WebViews to a bare minimum to avoid web security issues such as cross-site scripting (JavaScript injection). However, care should be taken to minimize the frequency of prompting for user credentials. Instead, use an authentication token and refresh it periodically.

Git: Version Control System

It’s free and open source version control software. Git allows you to experiment with new application features and coding techniques with confidence. You can tackle new crazy ideas for your project while keeping your previous working copy safe and secure. The moment you realize you are developing your project in the wrong direction, you can easily and of course restore the previous version correctly.


Android uses the Android Studio program to support Android app developers. This program allows you to create a skeleton of your app without any hassle. By answering a few basic app questions, you can start building the app you’ve always dreamed of.
