Mobile apps have revolutionized our lives, from the way we conduct our businesses, to the way we educate or create and even find fun! This has made developing mobile apps one of the most interesting and interesting jobs in the world. Android is certainly the definitive leader in global mobile market share. This market leadership means an extremely high level of job security to Android developers.In the era of Android apps continue to connect users across the globe and enable users to connect in engaging and innovative ways, a career in Android development is growing more fulfilling, rewarding and demanded by the world economy. To be a successful Android designer, you have develop a range of skills and apply them at the right time and place for the best user experience to your users.

Here are the 10 most important qualities you must have to succeed in your career as developer for Android developer.

Android foundations

The most fundamental element of Android development is the programming language. The most preferred languages to create Android apps comprise Kotlin as well as Java. It is possible to utilize either Kotlin or Java - or even both at the same time--to develop apps. You need to be familiar with the core concepts for either of these two languages, including basics and syntaxes, collection framework multithreading, concurrency and multithreading functional programming, and generics.

For the layouts (user interface) for user interfaces in Android the application, we employ XML. Much like HTML, XML is also an XML markup language. It stands as eXtensible Markup Language. After the creation of these XML Layouts, they are linked to Kotlin/Java files where business logic is written.

For smooth XML layouts and write business logic in an integrated environment, there exists an effective tool, known as Android Studio. Android Studio uses Gradle, an advanced build toolkit for automatizing and managing the build process. In order to integrate Gradle into Android Studio, there is a plugin known as"the" Android plugin for Gradle. Before you can begin, you need to understand what Gradle is , and also how to use it specifically for managing external dependencies.

Gradle and Android plugin run independently of Android Studio. This means you can build your Android apps using Android Studio, the command line on your machine or on machines which Android Studio is not installed (such as continuous integration servers). If you do not have Android Studio, you can learn how to build and run your app from commands.

Interactivity on Android

The user experience with Android apps must be taken into consideration with the utmost importance. Responding to incidents using callsbacks, using appropriate gestures such as dropping and drag, providing proper keyboards for user input as well as using pan and zoom at the correct place play essential roles in delivering the seamless user experience. They're not big, but are extremely beneficial in improving user interaction. Most importantly, the interactions with users are performed in an Android component known as Activity.

An Activity is a single specific thing that the user is able to do. Almost all Activities interact with the user, and the Activity class is in charge of creating a window for you that you can use to create the user's interface.

The Android device is available with a variety of screen layouts. Screen orientation is one of them. It is possible to choose either landscape or portrait. Each Activity can exist in either portrait or landscape mode. When the screen is rotated the activity that is currently running is destroyed and recreated in a fresh orientation. A stable activity must be ensured even when the screen orientation changes.

Android UI

An application isn't complete if it lacks modern UI. A program may have useful capabilities, but if it does not adapt to the latest UI guidelines, then it's likely to be a failure.

Utilizing RecyclerView to build lists and grids Utilizing ConstraintLayout to design complicated layouts, incorporating animations to increase the user experience, using appropriate menus, observing the guidelines of Material Design and using vector drawables instead of the raster graphics are just a few of the most fundamental guidelines that every developer must adhere to in their applications.

When designing layouts, one should not forget to consider the different screen types of devices. The exact same app must appear different for different devices. For instance, the screen on tablets should have dual-pane layouts to effectively utilize a widescreen. While on a smartphone it should have a single-pane. This could be accomplished with the help of Fragments. Additionally, in several cases, you might need to alter the Views to meet the requirements of your business. This is possible by designing custom components for your Views.

Implementing navigation

Navigation refers to the interactions that let users move across, into and back out of various pieces of content in your app. There are a variety of UI elements that permit you to design and implement an effective UI navigation.

The most basic of them will be the App bar which is also known as Toolbar. In your Toolbar you can include a popup menuor menu icon, and add a navigation drawer icon. The navigation drawer icon allows you to switch between opening and closing the drawer, which is a further element that can be used to create a more efficient navigation. The navigation drawer permits you to add menu items that will allow you swap out fragments of your current Activity or to perform additional actions.

Another option for navigation is A BottomNavigationView which allows you to change between various Fragments within the same activity by using tabs on in the lower part of the display. If you need to make use of tabs that are attached to the Toolbar and swipe between different pages (different pages), then ViewPager is the best option.

The intention of the user is the most crucial element of navigation. Users may want to start a new Activity or return to the previous Activity or share information with another app. This goal can be accomplished via Intents in Android. If you are aware of your desired Activity , then use Explicit Intent otherwise use Implicit Intents. You're always able to modify your intents.

The most important thing is that the The Navigation component of Android Jetpack helps in implementing navigation, from simple buttons to more sophisticated patterns, such as bar-like navigation or the drawer. It is worth taking a look at this component prior to starting to implement navigation on Android.

Android testing

Your app's users interact with it in various ways such as pressing the Submit button to downloading data onto their devices. In this regard, you should experiment with a variety of scenarios and interactions when you iteratively develop your app. The most popular testing tools are Expresso, Junit, Mockito, Robolectric and UI Automator.

Working with data

Data is an integral part of your application , and it should not be left out. It is possible to pull data from the internet, request data from the local database, save user preferences and do data handling.

For local databases, use Room database that is part of the Android Jetpack architecture component. You might want to share your database outside your app securely with ContentProvider.

To store a tiny amount of data like key-value pairs or types of objects, you can use Jetpack's DataStore which utilizes Kotlin coroutines and Flow to store data.

If you want to bind your UI elements within your layouts to a data source in your app using an declarative format, make use of Data Binding Library.

To manage files within your application, benefit from the massive file system APIs provided to you.

Most importantly, to access the information over the internet (i.e. when consuming REST APIs) Utilize the Retrofit 2 library, which is a gift by Jake Wharton to all Android developers.

Notifications

Notifications are one of the best methods to increase engagement with users. They appear outside of your app's UI , providing the user with reminders, notifications from others or other information that is timely from your application. Users can click on the notification to launch your app, or take an action directly by clicking the notification. You can make notifications, alter the layout, add actions to it and even combine several Notifications by using Notification channels.

Firebase on Android

If you're not a fan of being a backend programmer, Firebase on Android is the right choice for you. Firebase is a mobile platform that helps to quickly build high-quality apps and increase your user base and earn more cash. Firebase offers a variety of utility features to make the life for an Android developer simple.

To ensure that your application is visible on Google search results, you can make use of Firebase App Indexing API. Cloud storage, as well as the cloud's firestore to store data in your server. If you're looking to automate run backend scripts in response to events initiated by Firebase features or HTTPS requests, then use Cloud Functions. The next is Firebase Cloud Messaging (FCM) which allows you to push notifications to clients. Using FCM it is possible to notify an app on your client that a new email or other data is available to sync. Utilize Firebase Crashlytics, which is an extremely lightweight real-time crash reporting tool that can help you prioritize and fix stability issues. If you've ever used deep links within your application Try Dynamic Links. With Dynamic Links your customers get the best available experience on the device they access your link.

Android security

Android has built-in security features that significantly reduce the frequency and impact of application security issues. You can safeguard the users' privacy by utilizing permissions. Use secure sharing of data with signature-based permissions. Manage data security using internal storage as well as external storage as ContentProviders carefully. By default, don't export any Android component, like ContentProvider Services, ContentProvider or BroadcastReceiver in the event that you have to.

Android has limited the capabilities of WebView down to its bare minimum to avoid web security issues like cross-site scripting (JavaScript injection). But still you need to be careful and reduce the frequency that you request your user's password. Instead, opt for an authorization token, and then refresh it at regular intervals.

Git: Version control system

Git is an open-source and free software that is used to manage version control. Git lets you play with new features of the application and programming techniques with confidence. You can come up with new wild concepts for your project and your previous working copy stays secured and safe. In the event that you find you've shifted your project in the wrong direction, you can back up your old version hassle-free and course correct.

As the world is moving ever closer to the mobile world, Android app developers can be sure to find an audience for their creations or provide a significant benefit to companies in need of the skills to develop mobile apps.
