Creating your own video game for a mobile platform is an exciting but challenging path that requires a systematic approach and a willingness to learn new technologies. Many beginners, wondering where to start writing a game on Android, immediately rush to look for complex programming tutorials, forgetting about fundamental preparation. In fact, the development process begins long before the first line of code is written, and a successful start depends on the right choice of tools and understanding of the architecture of mobile applications.
Mobile game development is fundamentally different from development for PCs or consoles, since optimizing battery resources, managing touch input, and adapting to thousands of different device models are critical here. You have to immerse yourself in a world where productivity is at the forefront, and every megabyte of memory counts. Don’t be intimidated by the amount of knowledge: the industry offers many ready-made solutions that allow you to create high-quality projects even without a deep background in programming.
In this article we will analyze all stages of preparation, from choosing a programming language to publishing on Google Play, so that you have a clear map of actions. You will learn which Integrated development environments (IDEs) are industry standards, and why the choice of engine can determine the fate of your project. Let's define a vector of movement that will allow you not to abandon the idea halfway, but to bring the prototype to a full release.
Selecting a programming language and ecosystem
The first and most important step is to determine the technical stack on which your application will be built. For native development for Android, the Java and Kotlinlanguages are traditionally used. Kotlin is now Google's preferred choice due to its conciseness and security, but Java still has a huge base of documentation and libraries. If you plan to write a game from scratch without using heavy engines, knowledge of one of these languages is a must.
On the other hand, most modern games are created on cross-platform engines such as Unity or Godot, which use their own scripting languages. For example, Unity is based on C#which is easier for beginners to learn than Java and has a powerful memory management system. Godot offers its GDScript, which is syntactically similar to Python, which makes the entry into development as smooth as possible.
⚠️ Attention: Don't try to learn all languages at once. Choose one stack (for example, Unity + C#) and focus only on it until the first prototype is released, otherwise you risk getting confused by syntax differences.
The choice between native development and engines depends on the genre of your game. For simple 2D puzzles or text quests, native Android Studio tools may be sufficient, which will ensure a minimal APK file size. However, for 3D shooters, complex RPGs or projects with rich graphics, the use of a specialized one is practically no alternative. SDK game engine is practically no alternative solution.
Preparing the working environment and installing the SDK
After selecting the language, you need to prepare the computer for operation. The basic tool for any Android developer is Android Studio. This is the official IDE from Google, which includes emulators, debuggers and, most importantly, Android SDK (Software Development Kit). Even if you use Unity, having the Android SDK components installed is often required to build the final APK or AAB file.
The installation process requires care: when you first launch Android Studio, it will offer to install the necessary packages through the SDK Manager. You will need to select a specific version of Android (API Level) for which you will develop. It is recommended to install not only the latest available version, but also one of the previous ones (for example, Android 10 or 11) in order to test compatibility your application on different devices.
In addition, to debug on a real device, you must activate developer mode on your smartphone. To do this, go to Settings → About phone and quickly click on the build number seven times. After this, an item For developerswill appear in the menu where you need to enable USB debugging. This will allow you to run and test the game directly on your phone connected to the computer with a cable.

Review of popular game engines
Choosing a Game Engine is a decision that will determine your capabilities in creating graphics, physics and game logic. The market leader has remained for many years Unity, which is famous for its huge asset store, strong community support and flexibility. More than 50% of all mobile games are created on Unity, which guarantees ready-made solutions for any mechanic, from a simple jump to complex artificial intelligence.
The second popular option is Unreal Engine, which sets the standard for high-quality 3D graphics. If your goal is to create a photorealistic shooter, then Unreal may be preferable, although it is more resource-intensive on a mobile device and is more difficult to learn for a beginner. For 2D projects, it is also worth paying attention to Godot or Defold —lightweight engines that are great for indie developers.
The table below compares the main characteristics of popular engines for mobile development:
| Engine | Language | Graphics | Difficulty |
|---|---|---|---|
| Unity | C# | 2D / 3D | Medium |
| Unreal Engine | C++ / Blueprints | High 3D | High |
| Godot | GDScript | 2D / Easy 3D | Low |
| Defold | Lua | 2D | Low |
It is worth noting that many engines allow the use of visual programming (nodes), which can be a great start for those who are afraid of code. However, to create truly unique mechanics, knowledge of the basics of programming is still required. The choice of engine also affects the size of the final file: heavy engines can significantly increase the weight of the application, which is critical for users with limited traffic.
Is it worth writing your own engine?
Creating your own game engine from scratch is a great way to deeply understand how computer graphics and the game loop work. However, for a commercial product this is almost always a bad idea, as you will spend years developing tools instead of making the game itself. Use ready-made solutions.
Basics of mobile games architecture
Development for Android has its own specific features that must be taken into account when designing the application architecture. Unlike PC games, a mobile app goes through various Lifecycle states. The game should be able to correctly pause when there is an incoming call, save progress when minimized, and quickly restore when returning. Ignoring these aspects will lead to crash and negative reviews.
The most important aspect is memory management. Mobile devices have a limited amount of RAM, and the Android operating system can terminate your game at any time if it consumes too many resources. It is necessary to use Garbage Collector (garbage collector) correctly, avoid creating unnecessary objects in the Update loop and timely free textures that are no longer needed.
It is also worth thinking about the input system in advance. The touch screen does not have tactile feedback from the buttons, so the interfaces should be larger and the click zones more forgiving (forgiving of inaccuracies). In addition, you need to provide support for different screen aspect ratios, from elongated modern flagships to older tablets, so that the important interface is not cut off by the edges of the display.
⚠️ Attention: Always test the game on a real mid-range device. Emulators and powerful flagships of developers will not show the performance problems that the majority of users will experience.
Optimizing code and resources is not the final stage, but an ongoing process. Using texture atlasescompressing audio formats and object pooling (object pooling) are standard techniques that every mobile developer should master. They allow you to keep the number of frames per second (FPS) stable even on weak devices.
Use the Profiler in your engine or Android Studio constantly. It shows how much memory is consumed and where delays (lags) occur, helping to find performance bottlenecks.
Graphics, assets and sound
Visuals and sound create atmosphere, but in mobile development they are subject to strict technical requirements. Graphics must be optimized: the number of polygons in 3D models is limited, and textures must be compressed into formats that are understandable for video cards of mobile devices (for example, ASTC or ETC2). Using assets that are too heavy will result in long loading times and heating of the smartphone.
Beginners do not have to be artists or composers to search for graphics and sounds. There are many asset stores such as Unity Asset Store, itch.io or Kenney.nl where you can find free or paid assets. It is important to keep an eye on licenses: some sets are free for personal use only, and require the purchase of a license or attribution for commercial publication.
Sound also requires optimization. It is better to store long music tracks in a compressed format (OGG, MP3), and short sound effects (gunshots, jumps) in an uncompressed WAV for quick access. The wrong choice of format can lead to playback delays or an increase in the size of the application by several times.
Testing, debugging and publication
The final stage before release is thorough testing. It includes not only searching for bugs, but also checking the usability of the interface (UX). Ask your friends to play your game without giving them any instructions. If they can't figure out what to do, or the interface overlaps important elements, then some work is needed. Debugging tools, such as Logcat in Android Studio, will help you track down errors in real time.
To publish your game, you must register with Google Play Console. This is a paid procedure: the fee is $25, which is paid once when creating a developer account. After payment, you get access to the control panel where you can upload application files, fill out a description, add screenshots and videos.
The moderation process on Google Play takes from several hours to several days. Algorithms and live moderators check the application for compliance with security policies, the absence of malicious code and copyright compliance. It is important to carefully fill out the content rating form and indicate the target audience.
⚠️ Attention: Google Play rules change frequently. Before each publication, be sure to check the Developer Policies section of the console to ensure your app is not rejected due to outdated permissions or advertising requirements.
After successful completion of moderation, the game becomes available to users. However, the developer’s work does not end there: it is necessary to monitor statistics, read reviews and release updates that correct errors and add new content. This is the only way to build a loyal audience.
Publishing on Google Play is just the beginning of the journey. The success of the game depends on constant updates, working with the community and analyzing user retention metrics.
Frequently asked questions (FAQ)
Do you need to know mathematics and physics to create games?
Basic understanding of linear algebra (vectors, matrices) and trigonometry is highly desirable, especially for 3D development. However, modern engines take on most of the complex calculations by providing ready-made physics engines. For simple 2D games, a school course in mathematics is enough.
How long does it take to create the first game?
Creating a simple prototype (a clone of Flappy Bird or Arkanoid) can take from 1 to 3 weeks, subject to training in the process. The development of a full-fledged commercial project usually takes from 3 to 6 months or more, depending on the complexity of the mechanics and the volume of content.
Is it possible to write games on Android directly from your phone?
Theoretically, there are mobile IDEs (for example, AIDE or Termux), but they are extremely inconvenient for full-fledged development. The screen is too small, performance is limited, and the lack of a mouse and keyboard makes work difficult. For serious work, you need a computer (PC or Mac).
How to monetize your first game?
There are three main ways: selling the game (paid access), in-game purchases (IAP) and advertising (AdMob, Unity Ads). For beginners, the easiest way to start is with the integration of advertising, since this does not require a complex economy within the game, but requires careful implementation so as not to irritate players.
