Android App Development in 7 Easy Steps

There have been many innovations in the development industry over the past few years. There have been many arguments about development being more important than code and vice versa. All these arguments are myths. It is recommended that Android app developer be well versed in basic mathematical concepts.

You don’t have to choose between coding and development. Software development is a converging aspect of real-world technical situations. Coding and development are both interrelated. Both development and coding are simultaneous and go hand-in-hand. Development is a prerequisite and development is an application.

The entire development process revolves around algorithm design and logic building. Therefore, developers should be familiar with various graphical paradigms.

It can be difficult to get started with Android application development, especially if you have no prior programming experience. While Android app creation may seem difficult, it is possible with determination, curiosity, and motivation.

Although Android Studio has been around for a decade, the tutorials and reference materials are still very well-structured and in good condition. It is easy for beginners to navigate the complex process of building their first app with the help of a well-written document, and a large community.

Apps are now dominating all sectors of society, whether they be commercial or media. Every sector has a show-stealer application. Millions of Android developers work for multinational corporations (MNCs), start ups, and freelancers around the world.

You may end up creating the next great app, such as Netflix, Whatsapp or Twitter. Any productive app can be created, and used as a tool by students like the Adobe Scanner and the Microsoft Lens.

The Android Studio used to be limited to the Android operating system. But now, it can also work with iOS, giving more opportunities for beginners. One of the largest communities in the world is the Android developer community.

Many Android developers are skilled and eager to share their experience with other Android app designers. A sequential learning strategy is necessary to learn about all types of development.

Learn the 7 Most Important Steps to Learn Android App Development.
First, learn about any programming language.

Development and coding should not be separated. While development and coding are two different aspects of software development they should not be considered separate. Coding is an essential part of development. Two programming languages are used to drive the Android Studio: Java, and Kotlin. Both Java and Kotlin can be used to develop object-oriented programming languages. Kotlin is a more powerful programming language than Java, and can be used to develop cross-platform applications. An android app development company can help develop apps through their strategies.

Your project’s target audience will determine which language you choose. If you don’t have a target audience of around 1 million iPhone users, you can choose Java. Otherwise, you can learn Kotlin.

It will be easy to move from Java to C++ if you are proficient in C++ . Then you can take the next step and learn Kotlin. If you don’t have any programming languages to choose Kotlin, as it is the most user-friendly and bug-prone.

Kotlin was chosen to replace Java few years ago and it became the preferred language for App Development in the Android Studio. Java is still supported by the Android Studio to preserve the integrity of Java Developers. The documentation on Java libraries in Android is very detailed and extensive. Android Studio has an integrated feature that allows developers typecast Java codes into Kotlin without having to do any extra work.

Two ways can you convert Java code to Kotlin

  • To convert Java code into Kotlin open the Java Android Studio. Select > Convert Java to Kotlin .
  • You can also create a new file (File>> New > File/Class), then copy your Java code to that particular file.
Step 2 – Collect all relevant learning resources

You don’t have to be an Android expert if you don’t have any prior experience. There are many tutorials, blogs, courses, and videos online that you can reference. We recommend that you start with the is the official Android website.

This section explains in detail each of the libraries and their functionality. You can also check out blogs written by experienced Android developers. These developers have gone through the learning phase and can help beginners by sharing their experiences.

Many learners learn faster if they are presented with multimedia elements, such as videos tutorials. You might be one of these people and you could enroll in any of the Android development professional courses. Many courses can be found online. Some of these are very useful for budding developers, while others have an extensive alumni base.

You should ensure that you receive a certificate of completion for any course you are considering purchasing. There should also be enough assignments and assessments to allow you to self-evaluate, explore, and grow.

For information on the different implementation strategies, you can also look at the pre-existing GitHub repositories. You should read the README file before you fork any repository. This will ensure that all hardware and software requirements have been met.

Copyrights may apply to these repositories. Do not publish them. You can still learn from them and get ideas. GitHub allows you to communicate with the repository’s owner.

Step 3 – Install the android studio.

Open-source developer productivity tools are available that allow for collaboration and speed up the development process. This makes projects more scalable and reduces the critical path. Before you install productivity tools, ensure that you have the Android Studio, the most important tool.

The official website contains the Android Studio.

Android Studio includes everything you need to develop Android apps, from code editor to emulator. Before the introduction of Android Studio, Eclipse was the main IDE used for developing native Android apps. Android Studio works with all major operating systems, including Windows, macOS, and Linux.

This eliminates compatibility problems. Android Studio is recommended for elementary development. However, high-configured platforms like Visual Studio with Xamarin and Unity are highly recommended for graphics designers or game developers.

Many productivity tools can be used to speed up development processes, such as Jamboard, Cloud app, and TimeToggle. These tools keep developers alert and help them keep track of time and deadlines. This prevents them from wasting their time.

Multiple developers may be working on the same project in the real world. Collaboration plays an integral role in this scenario. Collaboration tools like GitHub, SourceTree and Meld are essential.

Step 4 – Get familiarized with data structures and algorithms

Before you take the big leap and create your first Android project, it is important to familiarize yourself with data structures in Java and other programming languages. While it is helpful to be familiar with the Android Studio object-oriented programming languages, it does not guarantee that your app will be efficient.
The following concepts are essential for maximizing the efficiency of Android and ensuring that it doesn’t crash:

  • Design The algorithm design is a mathematical method of creating and solving problems. Designing algorithms is part solution building. This includes dynamic programming, backtracking, divide-and-conquer, dynamic programming, greedy strategy, backtracking, and dynamic programming. The algorithm must take up the least space and be as fast as possible. It should also be consistent with any input.
  • Complexity: A program’s time complexity is the amount of time it takes to complete a task. Most commonly, the asymptotic notation big O is used to express the time complexity of an algorithm.

Three possible scenarios are:

  • The function that takes the least steps on input data of n elements is the best.
  • The worst case scenario is that function which performs the most steps with input data of size N.
  • The average case is a function that executes an average number steps on input data of n elements.
  • Space Complexity A space complexity refers to the amount of memory required to solve a particular instance of a computational problem. It is determined by the input characteristics. It refers to the maximum amount of memory an algorithm needs to execute a program, and then produce output, over its entire lifecycle.
  • Data Structures: Java and Kotlin have many data structures such as vectors, graphs and trees. They also include trie, linked list, stacks and queues. These data structures can help to compress time and space complexity. Data structures can reduce the time it takes to run an app and help you save memory. The number of floating point operations is significantly reduced, which helps to prevent the app from being crashed during execution.
Step 5 – Locating files and folders

It is important to know the locations and contents of all the files and folders in Android Studio. and MainActivity.kt are the most important files. These files change depending on the programming language used.

Understanding the XML folders is important as well as the folder responsible for hosting Gradle files. You can get lost in the activity and cause your project to lapse.

Step 6 – Enhance your debugging abilities

After you have learned how to use Android Studio, it is time to learn how to read and work on the logcat. This will allow you to identify the bug-ridden thread. It is common for code logic to have other or segmentation errors that are not highlighted in the editor. This can cause system failure. Space complexities can cause your app to crash during execution.

You can find the bug and fix it if you are able to read the logcat both in error and verbose modes. Otherwise, you could end up scanning thousands of lines of code.

Step 7 – Become part of the Android community

You must also become part of the global Android community. With millions of developers worldwide, the Android developers’ community is one of the most impressive communities. This community includes some of the original creators of Android Studio. Newbies can post questions about anything they find on the Android Studio and receive immediate assistance from the experienced developers. This community is both friendly and competitive, which allows you to grow as a developer.
